How to Calculate NPV in Excel: Step-by-Step Guide

Calculating Net Present Value (NPV) in Excel is essential for assessing the profitability of an investment. This step-by-step guide will walk you through the process using a simple NPV formula in Excel. Additionally, a downloadable Excel NPV template is provided for your convenience.

What is NPV in Excel?

NPV, or net present value, is a financial metric used to evaluate the profitability of an investment. It calculates the difference between the present value of an investment's cash inflows and the present value of its cash outflows, discounted by the required rate of return. The NPV formula is:

NPV = (Present Value of Cash Inflows) − (Present Value of Cash Outflows)

To calculate NPV, you'll need to determine the present value of expected future cash inflows and outflows. Let's explore how to calculate present value and then use it to calculate NPV.

How to Calculate Present Value in Excel

Present value is calculated using the formula:

Present Value = Future Cash Flow / (1+Discount Rate)

Where:

  • Future Cash Flow: Expected cash flow at a future point.
  • Discount Rate: Required rate of return.
  • n: Number of time periods until the future cash flow occurs.

Let's consider an example where you expect to receive $1,000 in one year with a required rate of return of 10%. The present value would be:

Present Value = 1,000 / 1+0.10 ≈ 909.09

How to Calculate NPV in Excel

Now that we know how to calculate present value, let's use this information to calculate NPV. Suppose you're evaluating an investment with cash flows as follows:

  • Year 1: $500
  • Year 2: $1,000
  • Year 3: $1,500
  • Year 4: $2,000

The required rate of return is 10%. Calculate the present value of each cash flow:

  • Year 1: $500 / (1 + 10%) = $455.45
  • Year 2: $1,000 / (1 + 10%)² = $909.09
  • Year 3: $1,500 / (1 + 10%)³ = $826.45
  • Year 4: $2,000 / (1 + 10%)⁴ = $751.36

Now, calculate the NPV:

NPV = (Present Value of Cash Inflows) = 455.45 + 909.09 + 826.45 + 751.36 ≈ 2,842.35

Download our free NPV Excel template to simplify the NPV calculation for your investments. The template includes an NPV calculator, and a separate tab provides instructions on how to use it.

To use the NPV calculator in the template, enter the required rate of return, cash flows for each year, and the investment duration. The calculator will then compute the present value of each cash flow and the overall NPV.

Conclusion

Net Present Value (NPV) is a crucial financial metric for evaluating investment profitability. The NPV formula calculates the difference between the present value of cash inflows and cash outflows, discounted by the required rate of return. By understanding how to calculate present value and NPV in Excel, you can make informed investment decisions.
