What is the difference between IRR and ROI for investment analysis?

IRR calculates the annualized rate of return that makes net present value zero, while ROI measures total percentage return over the entire investment period without accounting for timing of cash flows.

Can the IRR Calculator handle irregular cash flow schedules?

Yes, the tool accepts both fixed recurring amounts and irregular annual streams, allowing users to model diverse investment scenarios with varying return timing.

How does the NPV profile curve help interpret IRR results?

The NPV profile curve visually shows where the net present value crosses zero, with the IRR being the specific discount rate at that intersection point, helping users understand the sensitivity of their investment to discount rate changes.

What is Modified IRR (MIRR) and when should it be used?

MIRR adjusts the standard IRR by incorporating a separate reinvestment rate for positive cash flows, providing a more realistic return measure when reinvestment opportunities differ from the project's own rate of return.

About this tool

What IRR Calculator does

The IRR Calculator on Financial Toolset determines the annualized return implied by a series of cash flows, allowing users to compare investment deals with different timing patterns. By entering an initial investment and subsequent returns, the tool computes the Internal Rate of Return as the discount rate that makes the net present value of all cash flows equal zero. The site distinguishes itself by offering a visual NPV profile curve and a side-by-side deal comparison feature that highlights how timing affects returns, even when total profits are identical. Users can also adjust a reinvestment rate for Modified IRR (MIRR) calculations, providing flexibility beyond standard IRR outputs.
