Frequently Asked Questions

What NPV should I accept a project at?

Accept projects with NPV > 0, which means the project returns more than your required rate. Higher NPV means more value created. Always compare NPV across competing projects.

What is a good IRR?

IRR should exceed your cost of capital (hurdle rate). For Indian businesses, a good IRR is typically 15–25%. Compare IRR with bank FD rates (7%) and equity returns (12–15%) as benchmarks.
