Net Present Value Calculator

Calculate net present value for periodic cash flows using a discount rate per period, with discounted future cash flows and undiscounted total.

How to use

This NPV calculator discounts each periodic cash flow back to time 0 using the rate you enter. Enter signed cash flows: negative for outflows and positive for inflows.

  1. Enter the discount rate per period; it must be greater than -100%.
  2. Enter CF0 followed by CF1, CF2… separated by commas or lines.
  3. Calculate NPV and the present value of future cash flows.

How it is calculated

NPV=Σ CFₜ÷(1+r)ᵗ, starting at t=0

Example

Example: cash flows -1000, 400, 400, 400 at 10% produce a small positive NPV because discounted inflows slightly exceed 1000.

Important notes

This is a mathematical estimate, not investment advice. The discount-rate period must match the cash-flow period.

Frequently asked questions

Is CF0 discounted?

No. CF0 is at time 0, so its discount factor is 1.

Is this XNPV?

No. This calculator assumes equally spaced periods; irregular dates require an XNPV-style calculation.

Is this calculator free?

Yes. It is free to use and requires no account.
