NPV & IRR calculator
Calculate the net present value (NPV) and internal rate of return (IRR) of a project from its initial investment and a series of future cash flows. Enter the cash flows separated by commas, one per period.
What they mean
NPV discounts each future cash flow back to today at your discount rate and subtracts the investment: positive NPV means the project adds value. IRR is the discount rate at which NPV equals zero — compare it to your required return. NPV = −investment + Σ CFₜ/(1+r)ᵗ.
Frequently asked questions
What does a positive NPV mean? The project is expected to create value at your chosen discount rate.
How is IRR used? If the IRR is above your required rate of return, the project is generally worth pursuing.
