Frequently asked questions

What does IRR tell me about an investment?

It's the rate of return at which the investment breaks even in present-value terms — comparing IRR to your required rate of return (or cost of capital) tells you whether the investment is worthwhile.

How is IRR different from a simple average return?

IRR accounts for the time value of money — cash flows received sooner are worth more than those received later, which a simple average of returns ignores.

When should I use XIRR instead of IRR?

Use XIRR when your cash flows don't occur at perfectly regular intervals (e.g. dates vary or amounts are added irregularly) — IRR assumes evenly spaced periods.
