About the Redesign

If you visited this site prior to September 15th, 2018, you've no doubt noticed that I've since launched a complete redesign of the website.

If you're not happy with the new design, I sincerely apologize. I would have preferred to keep the old desktop design, but considering the majority of my site's users are now accessing the site from small-screen, touch-enabled, mobile devices, and considering Google is now penalizing websites for not being mobile/thumb friendly, I was left with no choice but to switch to a responsive, mobile-first design.

The good news is that now that I have combined the three separate versions of the site (mobile, desktop, and ad-free member) into a single design, this will 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 (within the "Calculator Preferences" expandable panel).

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

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

APY:APY:Annual percentage yield:Annual percentage yield:

Annual percentage yield:

Given the number of months and interest rate, this is the annual percentage yield (APY) of the certificate of deposit.

APY (also know as Effective Annual Rate, or EAR) is a formula used by investors to compare one quoted interest rate with another -- because savings institutions like to quote their interest rates in ways that make them appear higher than they actually are. The APY formula allows investors to compare apples to apples -- regardless of the method used to quote the rates.

If you would like to save the current entries to the secure database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.
