CategoriesBusiness & Finance

MIRR stands for Modified internal rate of return, a finance abbreviation.

Variant of IRR that assumes positive cash flows are reinvested at a specified rate, usually the cost of capital, and that outflows are financed at a set rate. The result is a single, usually more conservative, annual return figure.

Example: The project's IRR looks like 32 percent, but its MIRR at a 9 percent reinvestment rate is only 18 percent.

Usage notes

MIRR solves two problems with IRR: the possibility of multiple answers when cash flows change sign and the unrealistic assumption that interim cash earns the IRR. Excel provides an MIRR function that takes both a finance rate and a reinvestment rate. Despite its advantages, MIRR is used far less often than IRR in practice.
