Internal Rate Of Return Calculator

Use this calculator to calculate an Internal Rate of Return! Inputs include regular deposits and withdrawals, up to 20 irregular withdrawals, and whether to calculate based on deposits at the beginning or end of the period.

The Internal Rate of Return or “IRR” is an important concept in math, finance and economics. It is frequently used to find out how attractive an investment is. The IRR will give you a measure of how much, in percentage terms, the yield will be for the given investment. The IRR is calculated by setting the Net Present Value to zero.

The Calculated IRR is in yearly terms even if you use a different period for withdrawals and payments or a different start and end date. That is, it will give you the equivalent interest rate per year with the selected values.
