When should I use XIRR instead of IRR?

Use XIRR whenever your investments and withdrawals happen on irregular dates — real brokerage or business cash flows almost never land on perfectly even annual intervals.

What if the calculator shows no result?

XIRR requires at least one negative and one positive cash flow — if all your entries are the same sign, or the numbers don’t converge to a sensible rate, no result is shown rather than a misleading guess.

XIRR Calculator

Investing

Calculate the annualized return on a series of cash flows made on irregular dates.

Display currency

Changing the display currency only changes the symbol shown — amounts aren't converted, since this tool doesn't use live exchange rates.

Enter each cash flow with its date. Investments (money going out) are negative; returns and the final value (money coming back) are positive.

How this is calculated

XIRR solves for the discount rate that makes the net present value of all dated cash flows equal zero, accounting for the exact number of days between each cash flow — solved numerically (Newton-Raphson with a bisection fallback), since irregular-interval cash flows have no closed-form solution.
