## Calculating Net Present Value and Net Future Value Shown above is an HP 10bII calculator. There is no easier way to calculate NPV or NFV than with a calculator.

## Introduction

Without getting into the fancy equations, I'm going to show you how to plug numbers into an HP baII+ calculator to find net present value (NPV) and net future value (NFV). If you are following along with a calculator, make sure the calculator is set for payments to occur at the end of the month. Also, make sure that that periods per year is set to 1. The analysis of investment projects is carried out using discounted cash flow (DCF) analysis. Performance criteria such as net present value (NPV) needs to be known to understand if a project is worth undertaking. NFV may be obtained indirectly by compounding the NPV by the number of years of the project life. To find the net present value of cash payments we need to first clear the calculator by pressing the orange shift key, then press the "C ALL" key. Next, follow the instructions to save cash flow and interest data from the example to the calculator.

## Buttons Used To Calculate NPV & NFV NPV calculation formula as well as the NFV calculation can be made with a calculator. This photo of an HP 10bII+ Calculator show the exact buttons that are used to calculate NFV and NPV.

## Example

Imagine that you will receive \$100 at the end of each year for the next 3 years, \$300 at the end of Year 4, \$600 at the end of Year 5, and \$700 at the end of Year 6. At the time, other investments of equal risk earn 12% annually, what is its PV?

Step 1: Type 0, then press the "CFj" button

Because the payments are being made at the end of the year we won't have a payment for year zero. All payments will be positive since they are cash inflows.

Step 2: Type 100, then press "CFj" button three times

The first time you press "CFj" you will save 100 as the first cash flow. The next two times you press "CFj", you will save 100 as cash flow 2 and 3.

Step 3: Type 300, then press "CFj"

300 is saved as cash flow 4

Step 4: Type 600, then press "CFj"

600 is saved as cash flow 5

Step 5: Type 700, then press "CFj"

700 is saved as cash flow 6

Step 6: Type 12, then press "I/Y"

Now that all of our data is in the calculator we can solve for NPV. Press the orange shift button, then press the "NVP" button labeled in orange. Your answer should be \$1,125.94.

Now we can solve for NFV. Since this particular calculator does not have a NFV button we are going to have to utilize the TVM keys to find our answer. Start off by pressing the orange shift key, then press the "C ALL" button to clear the TVM function.

Step 1: Type 6, then press the "N" button

Step 2: Type 12, then press the "I/Y" button

Step 3: Type -1,125.94, then press the "PV" button

Step 4: Type 0, then press the PMT button

Now you can solve for the FV by pressing the "FV" button. The answer should be \$2,222.41.
