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.

Net Present Value (NPV) Calculator

This calculator will calculate the Net Present Value (NPV) for a series of future uneven cash flows. Plus the calculator will display a printer friendly Discounted Cash Flows Schedule that you can print out and use for sensitivity analysis. The Learn tab includes:

  • What is NPV?
  • What is Discounting?
  • What is the Discounted Cash Flow (DCF) Method?
  • Importance and benefits of conducting NPV analysis on prospective investments.

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".

DataData recordData recordSelected data record: None
Disc rate:Discount rate:Discount rate:Discount rate:

Discount rate:

Enter the rate you want the NPV Calculator to discount the entered cash flows. Note that the discount rate is also commonly referred to as the Cost of Capital. Enter as a percentage, but without the percent sign (for .06 or 6%, enter 6).

Begin year:Begin year:Year of initial investment:Year of initial investment:

Year of initial investment:

Optional. If you would like the calculator to populate the Year column with the actual year labels, enter the 4-digit year of the initial outflow (capital outlay). Otherwise leave blank. Note that if you make changes to this field after creating and/or completing the cash flow entry form, the entry form will be cleared. So be sure you are happy with this entry before creating and completing the entry form.

# of yrs:# of years:Number of years to include:Number of years to include in form:

Number of years to include in form:

Enter the number of years you would like included in the outflow/inflow form. Optionally, if you entered a 4-digit start year you can enter the 4-digit end year. In either case, this is a required field. Note that if you make changes to this field after creating and/or completing the cash flow entry form, the entry form will be cleared. So feel free to enter more years than you think you might need as the calculator will simply ignore any extra blank years.

Year entry column:

If you entered a 4-digit year above, then this column will be automatically populated with the appropriate years based on the year entered in the line above.

Outflow entry column:

Enter the initial outflow amount on the first line (required) and then on any subsequent lines where additional amounts were invested (enter as positive values). Note that numbers entered in this column are usually entered as negative values when using an NPV spreadsheet function, however this NPV Calculator converts the values to negative for you.

Inflow entry column:

Enter cash inflows in the years they are projected to be received. You must have at least one value in this column for the NPV calculation to begin.

Net CF:Net cash flow:Net cash flow:Net cash flow:

Net cash flow:

The is the sum of all outflows less the sum of all inflows.

# of years:# of years:Number of years:Number of years:

Number of years:

This is the total number of cash flow years that were included in the calculations -- which includes the year of the initial cash outflow.

NPV:NPV:Net Present Value:Net Present Value:

Net Present Value:

This is the total of all discounted cash flows (NPV). If this result is positive, the project is considered to be desirable. If the NPV is a negative number, the project is considered to be undesirable.
