What is the difference between IRR and MIRR?

IRR assumes cash inflows are reinvested at the same rate as the project's return, while MIRR allows users to specify separate financing and reinvestment rates, providing a more realistic measure of a project's profitability by accounting for the actual cost of capital and expected return on intermediate profits.

Can I use the MIRR calculator for projects with irregular cash flow timing?

The calculator is designed for periodic cash flows entered by year (Year 1 through Year 5). For projects with irregular timing between cash flows, users may need to adjust the inputs or use a different financial analysis tool that handles exact date-based cash flows.

What happens if I don't enter values for all five years?

Users can leave years blank if they have fewer than five cash flow periods. The calculator will only consider the years with entered values when computing the modified internal rate of return.

Is the MIRR result affected by the order of cash inflows and outflows?

Yes, the calculator processes cash flows in the order entered, with the initial investment typically entered as a negative value or separate from subsequent inflows. The timing and sequence of positive and negative cash flows directly impacts the calculated MIRR percentage.

About this tool

What MIRR Calculator - Modified Internal Rate of Return does

The MIRR Calculator on Omni Calculator determines the modified internal rate of return for investment projects with periodic cash flows. Users input an initial investment amount, subsequent inflows and outflows across up to five years, along with financing and reinvestment rates. The tool outputs the MIRR percentage, representing the project's profitability after adjusting for the timing of money and a specified reinvestment rate on interim profits. This provides a more accurate profitability measure than the traditional internal rate of return by accounting for realistic reinvestment assumptions. The result helps users compare mutually exclusive investments and assess which project offers the highest expected return. The site also links to related calculators for present value, future value, and compound interest if users need additional financial analysis tools.
