IRR is the break-even discount rate for an investment. A project is generally accepted if its IRR exceeds the required rate of return (hurdle rate). It is widely used in private equity and project finance to express returns as a single percentage.
Formula
0 = Σ [Cash Flowₜ ÷ (1 + IRR)ᵗ] − Initial Investment
Example
If a fund turns ₹100 into ₹200 over 5 years, its IRR is roughly 15% per year.
