What is Internal Rate of Return (IRR)?

IRR is the discount rate that makes the net present value (NPV) equal to zero. It represents the expected annual return rate of a project. A higher IRR indicates a better investment. This tool uses an iterative approximation method to calculate it.

What is the difference between IRR and NPV?

IRR returns a percentage (the rate of return), while NPV returns an amount (the value of the project). Use them together: IRR tells you whether the return exceeds the cost of capital, and NPV tells you whether the project creates value. This tool shows both at the same time.

How do I handle irregular cash flows?

This calculator supports adding any number of period cash flows (inflows and outflows). Each period can have its own amount, making it suitable for evaluating irregular returns, staged investments, and similar scenarios.
