NPV & IRR Calculator — free online
You have a project or an investment in front of you, and a row of numbers: money going out, money coming back over the years. The hard part is turning that into a clear yes or no. We added a free tool that does it — NPV & IRR Calculator — right in your browser.
What it does
You enter your cash flows and it works out the net present value (NPV), the internal rate of return (IRR), and how long it takes to pay back. That's the math people usually do in a spreadsheet, ready in a moment.
Nothing leaves your device
It all runs in your browser. Your numbers are never uploaded and never saved anywhere. When you close the page, they're gone — nothing is stored on a server.
How to use it
- Open the NPV & IRR Calculator and type in your starting amount and the cash flows for each period.
- Set your discount rate so the present value is calculated the way you want.
- Read the NPV, IRR and payback right on the page, and use them in your decision.
It's free with no limit. There are more small tools on the Apps page.
