How this calculator works
The IRR Calculator gives you a fast way to turn a simple investment setup into an annualized return signal. IRR stands for Internal Rate of Return, and it is useful when you want to compare one opportunity against another, pressure test exit assumptions, or create a quick screening view before opening a deeper model. Instead of manually translating cost, proceeds, and holding period into a comparable annual return number, the calculator summarizes the result directly so you can move faster.
This page now supports a more standards-based review with interim annual cash flows, end-of-year or mid-year timing, annual fee drag, exit costs, tax on gains, hurdle-rate NPV, and MIRR. That makes the result more useful for shortlist reviews, portfolio comparisons, and screening discussions while still staying lighter than a full underwriting workbook.
- Enter the values requested by the calculator and run the scenario.
- Review the headline return metrics and the visual mix together.
- Use copies or exports to compare multiple investment cases side by side.

FAQs
What does IRR stand for?
IRR stands for Internal Rate of Return, a common measure used to compare the annualized attractiveness of an investment.
Is this a full IRR model?
No. It uses the existing shared calculator logic for a compact return view and is best treated as a screening tool.
Can I use this for irregular cash flows?
This version handles regular interim annual cash flows with timing convention options. For fully irregular dated flows, use a dedicated XIRR or cash-flow model.
Why is annualized return useful?
It makes deals with different holding periods easier to compare on a common yearly basis.
Should I rely on this for investment approval?
No. Use it as a fast comparison aid before preparing a full investment case with complete assumptions.
