How to use IRR Calculator

Provide the investment outlay and the projected cash flows, and the calculator will estimate the discount rate at which that stream breaks even in present-value terms.

What this calculator is for

This calculator is for capital budgeting, deal comparison, and investment-analysis coursework. It helps summarize uneven cash flows with a single annualized return measure, while reminding users that IRR has interpretation limits in more complex projects.

Tips

IRR can be misleading when cash flows change sign more than once, so pair it with NPV or simple cash-flow review when a project is complex.
Use realistic cash-flow timing and order because IRR is sensitive to when money arrives, not only to how much arrives.
