How this calculator works

NPV = sum of cash flow at time t / (1 + discount rate) ^ t, including time zero.

Before you use the result

  • Cash flows must be equally spaced. For dated irregular flows use XIRR. IRR is per period, not automatically annual. Multiple detected roots are rejected.

What is NPV Calculator?

NPV Calculator helps you compare discounted cash inflows with an investment's initial outlay.

The main result is net present value. The formula, example and assumptions below explain how to interpret it.

How to use NPV Calculator

Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.

  1. Gather equally spaced cash flows, starting at time zero and discount rate per period (%). Use values from the same situation or reporting period.
  2. Replace the example equally spaced cash flows, starting at time zero with your own value, then complete the other fields. Check the displayed units.
  3. Select Calculate and read net present value. Change one input and calculate again to compare a second scenario. Reset restores the original example.
  • Enter equally spaced cash flows, starting at time zero in the format shown by the example. Keep the same separators and row structure. Negative = invested / paid; positive = received. Include the initial investment as the first entry.
  • Enter discount rate per period in %, at least 0 and at most 100. Decimals are accepted.

NPV Calculator: a worked example

With the inputs below, the result is ₹-2,103.68 (net present value). Follow the example, then replace these illustrative values with your own.

Example inputs and output
Input or outputExample value
Equally spaced cash flows, starting at time zero-100000, 30000, 40000, 50000
Discount rate per period (%)10 %
Net present value₹-2,103.68

Understanding the NPV result

The main output is net present value, expressed in ₹. It applies to the inputs and operation you selected.

Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.

NPV Calculator: assumptions and common mistakes

A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.

  • Cash flows must be equally spaced. For dated irregular flows use XIRR. IRR is per period, not automatically annual. Multiple detected roots are rejected.
  • A projected return is an assumption. Check whether fees, tax and inflation are included before comparing products.

NPV Calculator FAQs

What does NPV Calculator calculate?

NPV Calculator helps you compare discounted cash inflows with an investment's initial outlay. Its main output is net present value in ₹.

What inputs do I need for NPV Calculator?

You need equally spaced cash flows, starting at time zero and discount rate per period (%). Negative = invested / paid; positive = received. Include the initial investment as the first entry.

Which formula does NPV Calculator use?

NPV = sum of cash flow at time t / (1 + discount rate) ^ t, including time zero.

What is a worked example for NPV Calculator?

Example inputs: Equally spaced cash flows, starting at time zero: -100000, 30000, 40000, 50000; Discount rate per period: 10 %. The result is ₹-2,103.68 (net present value).

How should I enter equally spaced cash flows, starting at time zero?

Enter equally spaced cash flows, starting at time zero in the format shown by the example. Keep the same separators and row structure. Negative = invested / paid; positive = received. Include the initial investment as the first entry.

How do I choose discount rate per period?

Enter discount rate per period in %, at least 0 and at most 100. Decimals are accepted. The example uses 10 %; replace it if your circumstances differ.

How should I read net present value?

The main output is net present value, expressed in ₹. It applies to the inputs and operation you selected.

Why might my NPV Calculator result differ from my records?

Cash flows must be equally spaced. For dated irregular flows use XIRR. IRR is per period, not automatically annual. Multiple detected roots are rejected. Differences in entered values, units or rounding can also change the comparison.

Can I compare two scenarios in NPV Calculator?

Yes. Note your first net present value, change equally spaced cash flows, starting at time zero or another input, and select Calculate again. Editing a field clears the old result so it is not mistaken for a new calculation.

Is NPV Calculator free, and where are my inputs calculated?

This calculator is free to use without signing in. Its formula runs in your browser; calculator inputs are not sent to a calculation API. The inputs reset to the example values when you reset the form or start a fresh page.
