XIRR calculator

Get the annualised return for dated cash flows on the actual/365 convention, with a discounted flow table and the solver's steps shown.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Paste dated flows to solve the annualised return.

This is the spreadsheet XIRR definition: each flow is discounted at an actual/365 day count from the first date, and the rate that brings the discounted column to zero is the annualised return. It is not CAGR, which needs one in and one out on fixed dates, and it is not a calendar-year return. Rates above 100,000,000 percent are refused; one-day windfalls annualise to numbers that large anyway.

Flows

One per line: date then amount, comma, tab or semicolon separated. Money out is negative, money back is positive.
Date orderISO dates (2025-01-01) ignore this
A display label only, up to 8 characters
More settings▾
Where the solver starts, 10 works for most portfolios. Flows with several sign changes may need a different one.

Paste up to 1 million characters and 2,000 flows. The first non-dated line is treated as a header and skipped.
