Quick guide
How to use this calculator
- Enter the cash flows, values, rates, timing, or portfolio assumptions named in the fields.
- Use one consistent period and currency convention throughout the scenario.
- Read the calculator-specific model limits before interpreting the result.
Calculation method
Calculation method
MIRR = (future value of positive flows ÷ present value of negative flows)^(1/n) − 1.
Model, simulation, root, square-root, and compounding outputs are estimates and are visibly marked approximate.
Worked example
Worked example
Enter time-zero and later flows plus periodic finance and reinvestment rates.
MIRR = (future value of positive flows ÷ present value of negative flows)^(1/n) − 1.
Supported inputs
Precision and limits
Visible input limits
Inputs support up to 12 decimal places and lists support at most 1,200 rows. Iteration and simulation bounds are displayed in their fields.
International scope
No exchange, tax system, reporting standard, currency, fund rule, trading calendar, or market convention is selected automatically.
Decision boundary
Outputs are entered scenarios, not valuations, forecasts, risk limits, executable trades, suitability decisions, or recommendations.
Calculator-specific assumptions
At least one negative and one positive cash flow are required; rows are equally spaced.
