New! Multiplication Table Exercise to Learn Times Tables

After getting feedback stating the Multiplication Quiz was too difficult, I decided to create an additional tool for learning times tables.

Specifically, this new interactive worksheet will ...

  • Display any size times table up to 1-12.
  • Display a blank entry field for each multiplication in the table.
  • Tell you if your answer is correct or incorrect after tabbing out of the field.
  • Allow you to switch between a Practice view and a Study view.
  • Allow you to print out a blank multiplication table, as well as a filled-in table, so you can practice and study offline.

New! Long Multiplication Calculator for Multiplying Decimals and Integers

Long Multiplication Calculator Image

I would have never guessed there would be a need for a calculator that multiplied numbers. That is, until I added a suggestion form beneath each section's calculator listing.

Low and behold, requests for a "Multiplying Decimals Calculator" started pouring in!

So I'm thrilled to report that I just launched a new Long Multiplication Calculator that shows how to multiply decimals, integers, and whole numbers ... without a calculator!

Specifically, this new calculator will ...

  • Give the product of the two numbers.
  • Display the long multiplication grid used to find the product.
  • Display buttons for each Multiplier digit, which when clicked will show its carryovers and multiplication steps.

From my perspective, it's one the coolest calculators I've ever created. I hope you agree!

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Redesign Launched!

After 18 months of working on it, I'm thrilled to report that I've finally launched the new design!

Of course, I may still have a lot of work to do depending on your feedback.

And as thrilled as I am, I also know I can't please everyone. So if you're not happy with the new design, I sincerely apologize.

To be honest, I would have much preferred to keep the old, much simpler desktop design. Unfortunately ...

  1. The majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices.
  2. Google is now penalizing websites for not being mobile/thumb friendly.
  3. I could no longer keep up with trying to maintain and improve three separate versions of the site (mobile, desktop, and member).

... so I felt I was left with no choice but to combine all three sites into a single, responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site into a single design, this will eventually free up a ton of my time for working to make the mobile-optimized calculators more desktop/laptop friendly.

In fact, some of the redesigned calculators already offer a desktop-optimized form that becomes visible when you increase the width setting of the calculator (setting within the "Calculator Preferences" expandable panel).

Finally, if the new page layout is not working for you, please Contact Me and let me know what device, operating system, and web browser (with version numbers) you are using so I can attempt to get the layout working for your setup.

Thank you in advance for your help and patience as I work to improve the redesign.

Redesign Test Underway!

I hope you are having a great summer.

If you're a regular reader of this "What's New" page, you're probably aware that I've been working on a site redesign for what seems like forever (March of 2017).

I won't bore you with all of the setback and restart details. Let's just say I've given up on countless occasions only to later re-acknowledge that I need to see this through to the end -- for better or worse.

Fearing repeat visitors wouldn't like it, I initially launched a demo page of the new design last summer hoping to ease my fears of breaking what might not need fixing.

Millionaire Calculator

Unfortunately I have yet to receive even a single word of feedback.

Recently a wise associate suggested that instead of waiting for someone to give me feedback on the demo calculator, I should just launch the redesign on 5 of my more popular calculators and measure what happens. That way, if the testing proves the redesign to be a major fail, I can just turn those pages back to the old design and get back to creating and improving calculators using the old design.

So that's what I've done. The following 5 calculators have been converted to new design.

If you feel strongly for or against the redesign, please let me know. Otherwise, if I don't hear from you, I will assume you don't have a preference one way or the other.

Thank you for your continued support!

Why Nothing New Lately?

In case you're wondering why I haven't created any new calculators of late, I thought I would let you know that I'm still busy working on the site. It's just that most of the work involves critical projects that are not visible.

EU GDPR Compliance:

Earlier this year, the European Union enacted a law referred to as the General Data Protection Regulation (GDPR) to supposedly help their citizens to get control over their online personal data. And even though my website is based in the U.S., I was still forced to comply since a small portion of my traffic are citizens of the EU. Considering the stiff fines for non-compliance, I had no choice but to spend nearly the entire month of May implementing changes to comply with the 85-page law.

Site Redesign Setbacks:

I have been working on a site redesign of the website since March of 2017. It was supposed to save me time since it will combine the three separate versions of the site (desktop, mobile, member) into a single version. But each time I get close to completing it, something major happens that either causes me to take time away from the redesign (Google HTTPS compliance, EU GDPR compliance, etc.), or to start over from scratch (Google mobile page-speed compliance, discontinuation of the mobile framework I used for the redesign, etc.).

Once again I'm about a month or so away from launching the redesign, but this time I won't be surprised if the powers that be come out with yet another law or policy/ranking/framework change that forces me to start over a 4th time.

Thank you for your continued patience.

Wishing You a Safe and Happy 4th Of July!

New! Daily Interest Calculator for Tracking Promissory Notes and Personal Loans

Daily Interest Calculator Image

This calculator was created in response to a site visitor who was looking for an easier way to track the running balance of loans made to others in the form of promissory notes. Furthermore, the notes have no prescribed payment, accrue 10% simple interest on a daily basis -- based on a 360-day year, and borrowers randomly decrease (pay down) and increase (add to) the principal owed.

Wow! It's no wonder the visitor was looking for an easier way to keep track of who owes how much at any given time.

I'm hoping this new Daily Interest Loan Calculator will be useful to aforementioned visitor, as well as to others who are also trying to keep track of these types of promissory notes, personal loans, or owner-financed arrangements.

Specifically, this new calculator will allow you to:

  • Calculate daily interest between dates or for a specified number of days.
  • Choose between simple or compounding daily interest.
  • Choose to base the daily rate on a 360, 364, or 365 days per year.
  • Calculate interest and payoff for a single period, or create a printable running-balance schedule for multiple transaction periods.
  • Change the annual interest rate for any interest period.
  • And, if you print out the running balance schedule, start from where you left off on your next use of the calculator.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Happy Easter!

-Dan

P.S. The new calculator was also added to the mobile version if you are accessing from a small-screen device, and to the Ad-Free Member Version.

Automatic Budget Generator Based On Income

Automatic Budget Generator Based On Income

Just letting you know that I just finished updating the Budgeting Percentages Average Calculator with the latest figures from the Consumer Expenditure Survey conducted by the U.S. Bureau of Labor Statics.

Simply enter your annual before-tax income amount and the calculator will instantly show you the average budget percentages and expenditures for other households in your income bracket -- for 14 main spending categories and up to 97 sub-categories!

Plus, you can then create a sample budget based on income that you can print out and use as a reference point for revising or setting up your own budget.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Happy Budgeting!

How Will The New Tax Bill Affect My Paycheck?

Free Online PayCheck Calculator

Like every year around this time, I have updated the federal tax withholding rates in the paycheck calculator.

However, given the major changes in the 2018 tax reform bill, this year I decided to keep the 2017 rates so you could compare your net pay before and after the tax bill is implemented by your employer.

2017 vs 2018 Tax Brackets

To see the difference between the two tax withholding tables, calculate your paycheck as usual and print out the report (leave the default Use 2018 Federal Tax Table selected).

Next, select Use 2017 Federal Tax Table from the new drop-down menu, then click "Calculate My Paycheck" again. Then print out the report to see what effect the new tax bill is having (or will have) on your take-home pay.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Happy Groundhog Day!

P.S. The update was also added to the mobile version if you are accessing from a small-screen device, and to the Ad-Free Member Version if you wish to save your entries in between visits.

Happy New Year and Site Redesign Update Update Update ...

Hope you had a safe and happy new year.

Since it's been a while since I last posted anything new on this page, I at least wanted to let you know I've been busy behind the scenes.

After failing to get any feedback on the Site Redesign Beta Page (as in zip, zero, none, nada), I decided to build the new design into the Ad-Free Member Version of the site to see if I can get any feedback from the members.

I'm happy to report that I have completed the member redesign and plan to launch it to the members this coming weekend.

Hopefully I will finally get the feedback I need to ease my concerns about launching the redesign for the free-with-ads version of the site. If not, or if I get complaints from the members, I will likely delay the free site launch until any complaints have been addressed and until web traffic slows down for the summer.

Thank you for your continued support and patience.

Wishing you a happy, healthy, and prosperous 2018!

New! Count Up Timer for Counting Time (and Money) From Past Event

Count Up Timer Image

A few months ago I became aware that a person dear to my heart was struggling to overcome an addiction to pills and alcohol. Later, out of the blue, I received an email from this person asking if I could create a sobriety calculator to help them track the time they've been sober.

Of course, since I love creating online calculators, and I love the person asking for my help, creating this new calculator was a Labor of Love in the purest sense of the phrase.

This new calculator will not only count up the years, months, weeks, days, hours, minutes, and seconds that have passed since a past date and time, but it can even be set to automatically update the next time you visit the page.

Plus, if the past event resulted in saving or earning money (quit smoking or working on a billable project), the calculator will even count up the money saved or earned.

This explains why I named it the "Count Up Timer" instead of the "Sobriety Calculator", because it can be useful for counting time (and money) for many other types of past events.

If you like the "Sobriety Calculator" and you know someone who is struggling to overcome an addiction, I invite you to share the new Count Up Timer with them.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Thank you!

P.S. The new calculator was also added to the mobile version if you are accessing from a small-screen device, and to the Ad-Free Member Version.

Free-Online-Calculator-Use.com Is Now Secure!

free-online-calculator-use.com https image

Just letting you know that you should now see a green padlock in the address bar whenever you access a web page on free-online-calculator-use.com.

That's because this past weekend, after many weeks of prep work, I converted the web site to "https". This means that all communication between the web site and your web browser will be encrypted.

If you don't see the green padlock, please contact me and let me know the web address of the page I missed.

New Design On Hold Until After Switch to HTTPS

In case you've been wondering why the new design hasn't been launched yet, I thought I'd give you an update.

Just before the planned launch date of the new design (September 30th), I discovered an issue with a Google module that broke the new design. It took nearly two weeks to resolve the issue, but by that time it was too close to Google's HTTPS deadline to launch.

What's the HTTPS Deadline?

Sometime after October 17, 2017, Google's Chrome web browser will start displaying a "Not Secure" message in the address bar for websites not using the HTTPS protocol -- even for sites like mine that don't ask for any sensitive personal information.

This is basically forcing all websites to purchase a secure certificate and to switch the beginning of their web address from "http://www" to "https://www", or risk losing visitors who might get scared away by the "Not Secure" message.

So Why Delay The Design Launch?

As with any big change to a website, there are always unforeseen issues that show up after the change. Therefore I've decided to delay the launch of the new design until after the conversion to https and any https-related issues have been resolved.

IMPORTANT! HTTPS Will Result In Lost Calculator Data!

If you use any of the calculators that allow you to save your entries in between visits, it's important to know that data saved using the HTTP protocol can't be accessed from the HTTPS protocol -- even though the data is stored on your own web browser.

Therefore, if you've saved any calculator entries to your web browser, please visit the applicable calculators and follow the instructions for transferring your data from http to https. Or, at the very least, print out the reports so you can re-enter the data once the conversion to https has been made.

Note that this does not apply to members of the secure, Ad-Free Version.

When Will The Conversion To HTTPS Occur?

I already have the site set up to be accessed by the HTTPS protocol. In other words, you can access the secure version of any calculator by adding "https://" in front of "www.free-online-calculator-use.com" in your web browser address bar.

The next and final step will be for me to turn on a redirect that will force all HTTP visits to go to the HTTPS version. But due to the loss of saved calculator entries that some users will experience, I will delay turning on the redirect for as long as I can.

Please Give Me Your Feedback On The New Design

The good thing about the https conversion delaying the launch of the new design, is that you still have time to offer your feedback on the beta page:

New Design Beta Page

Thank you for your patience and understanding.

-Dan

P.S. Switching to HTTPS means I will lose the social Like and Share counts I've spent 7 years working to earn. Your help in regrowing my HTTPS social Like and Share counts will be greatly appreciated!

New! Millionaire Calculator with Redesign Sneak Peek!

Millionaire Calculator Image

I have added a new calculator to the site for the primary purpose of getting your feedback from a sneak peek at the new design I've been working on since April.

As I posted back in May, the redesign is necessary to allow me to eventually combine the mobile, desktop, and member versions of the site into a single code base.

In turn, this will allow me to spend a lot more time adding and upgrading calculators.

The Launch

I still have a lot of work to do to build the redesign into all of the calculator pages, but I hope to be ready to launch the redesign within the next 2-4 weeks.

This preliminary launch will combine the mobile and desktop versions into one. The final step will be to build the redesign into the member version, which I hope to complete by year end.

What You Can Expect

If you typically access the site from a mobile device, you likely won't notice much of a change. That's because the mobile versions of the calculators are being incorporated into the new design (they already resize to fit any device).

On the other hand, if you typically access the site from a laptop or desktop computer, you will notice a significant change in the calculators and in the site navigation. I hope you find the changes to your liking, but please let me know if you don't.

In either case, the new redesign includes new features for saving entries and notes, as well as features for quick access to your favorite calculator(s). That is, if you are using a newer version of your web browser software.

Older Web Browser Versions

If you are using an outdated version of your web browser software (Firefox, Internet Explorer, Chrome, Safari, etc.), the redesign and save features may misbehave until you upgrade your browser to a newer version. I sincerely apologize if this is true in your case, but I've held off adopting the required technologies for as long as I possibly could.

Do You Prefer the Old "Desktop" Design?

If you find you like the old, outdated calculator design on the desktop version better than the new design, please let me know. I may decide to link to the old desktop versions from the redesigned versions. However, just know that the old versions will no longer be updated or supported.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements -- either with the calculator or the new design.

Thank you!

New Design In The Works!

In case you've been wondering why I haven't posted anything new lately, it's because I've spent the last 2 months working to combine all three versions of the website (desktop, mobile, member) into one responsive design.

The Problem: Being a one-person show, trying to maintain three separate versions of 241 calculators leaves little time for creating and improving calculators.

The Solution: Combine all three versions of the site into a single design that will resize to fit the screen of any device, and will accommodate both touch and mouse interaction.

The Plan: I have a new calculator ready to release, so the plan is to build the new design into just the new calculator at at first. I will then ask you to give me feedback on the new design until I get it right, before building it into all of the calculators.

My goal is to have the new calculator -- with the new design -- published to the site by this time next month. I will then post a link here so you to take a look and let me know what you think.

In the meantime I sincerely thank you for your patience.

-Dan

P.S. If you want to be one of the first to see the new design, be sure to subscribe to my Monthly "What's New" Email Update (signup form in right-hand column of all pages).

New Video! How to Use the Lender Loan Balance Calculator

I just finished my second "How to" video. This one attempts to demonstrate how to use the Lender Loan Balance Calculator.

So if you ever need to track the balance of a loan (either as a lender or as a borrower) when irregular, skipped, extra, or partial payments have been made, hopefully this new video will help you quickly get up to speed with the Loan Balance Calculator.

Click the following image if you wouldn't mind giving me some feedback on the video (please use the expandable feedback form beneath the calculator).

New! Pregnancy Countdown Calculator with Printable Calendar

Pregnancy Countdown Calculator Image

I created this new calculator to help me keep track of our youngest daughter's pregnancy term, but thought I'd add it to the site in case others might find it useful.

Now, whenever someone asks me how far along she is, I can refresh the calculator and tell them exactly instead of trying to do the date math in my head.

Just enter the baby's due date and this calculator will tell you, in days, weeks, and months, how far along and how long is left in a pregnancy term.

The calculated results also include a due date countdown meter, and a printable countdown calendar -- wherein each date cell displays the days, weeks, and months along and remaining, as well as the date's trimester.

Plus, you can even tell the calculator to remember the due date so the results will automatically recalculate whenever your revisit or refresh the page.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Thank you!

This new school calendar calculator will calculate the number of class days remaining in the school year.

Simply select the starting and ending dates and the calculator will generate an interactive school calendar wherein you can exclude "no school" days based on your own school's calendar.

Plus, the calculator even provides a printer friendly calendar with the number of days-left displayed in each date cell!

New! Student Loan Repayment Calculator For Up To 24 Loans!

Student Loan Repayment Calculator Image

This calculator was born out of an email I received from a Financial Aid Director of a large public university who was in search of a good calculator for parents and students to use. Of course, I couldn't resist when she accepted my request for her guidance.

Unlike other online student loan calculators that only handle 1 loan at a time, this new Student Loan Repayment Calculator will handle up to 24 separate loans (up to 4 loans per year for up to 6 years).

The new calculator will accommodate subsidized, unsubsidized, PLUS, and private loans, and allows you to play with the payment amounts to see how much interest you could save by paying more than the minimums.

And for unsubsidized loans you can even choose to begin making principal and interest payments right away, or just interest payments, or have the accruing interest added to the loan balance (interest capitalization).

Finally, you can either view and print a combined loan payment schedule for all loans, or a loan payment schedule for each individual loan.

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Thank you!

New! All-Possible-Combinations Calculator

Combination Calculator Image

Not sure if this calculator will be useful for anyone else, but after receiving the following from a site visitor I just couldn't pass up the challenge of making one that would accommodate the visitor's needs.

I want the 24 combinations for the numbers 9567. I would like the numbers in a list collated with the lowest to the highest. Hope you can direct me to the right calculator.

Done!

This new combinations calculator will accept any combination of up to 6 numbers, letters, or a combination of both (123456, ABCDEF, or 1A2B3C), and then generate a list of all possible combinations -- sorted to your preference.

Why limit the characters to 6? Because any more than 6 characters generates a result with more than 5,000 possible combinations.

Any guess as to how many combinations there are in a 12-character string? If you guessed 479,001,600 ... congratulations!

As always, please use the expandable feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Thank you!

Update: New Feature Added To Annual Salary To Hourly Pay Calculator!

Annual Salary to Hourly Pay Calculator

On A Salary, But Working More Than 40 Hours Per Week?

If so, then you'll appreciate the new feature I've added to the Hourly Pay Calculator.

If you are getting paid on a salary basis but you are consistently working more than 40 hours per week, you can now plug in the number of unpaid overtime hours you work per week.

The new feature will then search for an hourly wage that closely matches what an hourly employee would be earning when time-and-a-half for overtime is factored in.

This is useful for comparing a salaried-based job opportunity with an hourly-plus-overtime opportunity.

As always, please use the feedback form beneath the calculator to let me know if you discover any issues and/or have any suggestions for improvements.

Thank you!

Drive Time Calculator Now Available In App Stores

Drive Time Calculator available in app stores.

The Drive Time Calculator is the 4th calculator to be published to the app stores.

The major upgrade of the Drive Time/ETA Calculator and subsequent creation of the app all began on March 13, 2016. That was the day I received the following feedback:

"Please PLEASE make this in to an App"

And rest, as they say, is history.

Here is what others are saying about the app:

"This is one of the best if not the best trip calculator I have ever used....Thank you!"

"Great app, you couldn't ask for anything more."

"I like the comparison drive times, they are helpful and definitely sets this calculator apart from the rest, great job!"

"Awesome app.....not sure how to rate based on options....whichever is the highest rating that is what I rate."

You can now take this popular trip calculator with you wherever you go.

You can purchase and download this ad-free app (only $2.99) using any of the following methods:

QR Code for Drive Time Calculator App
  • Open a QR Code Reader on your device and point it at the QR Code at right.
  • Visit the Drive Time Calculator page and scroll down to beneath the calculator to click the app store badge applicable to your device.
  • Go to iTunes and search for "drive-time-calculator" or go to Google Play and search for the "drivetimecalc1" app.

As always, let me know what you think of the new app.

-Dan

P.S. I am in the process of creating app versions of all of the most popular calculators on the site -- in the order of their popularity (you can now see the current list here). If you have one you would like me to prioritize, please let me know.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
