Internal Rate of Return · NPV Analysis · Project Comparison
The Internal Rate of Return (IRR) is the discount rate that makes the Net Present Value (NPV) of all cash flows equal to zero. It's the annualised return an investment generates. If IRR > your hurdle rate, the project creates value. Enter cash flows period by period — negative for outflows, positive for inflows.

IRR Insights
Net Present Value (NPV) is the total value created by a project in today's dollars. Unlike IRR, NPV directly shows how much wealth a project adds. A positive NPV means the project earns more than your required return. It's generally preferred over IRR for capital allocation decisions.

NPV Insights
Compare two capital projects side-by-side across IRR, NPV, MOIC, and payback period. When IRR and NPV conflict — a common problem — this tool reveals which metric to trust and why, and shows the crossover discount rate where the rankings reverse.
