About IRR

Internal Rate of Return (IRR) is the discount rate that makes the Net Present Value (NPV) of all cash flows equal to zero.

How to Use

  • Enter your initial investment as a negative number (money going out)
  • Enter expected returns as positive numbers (money coming in)
  • Add multiple periods to reflect your investment timeline
  • Click Calculate to see your IRR

Interpreting Results

  • A higher IRR indicates a more profitable investment
  • Compare IRR to your required rate of return or cost of capital
  • If IRR exceeds your hurdle rate, the investment may be worthwhile

Formula

NPV = CF₀/(1+r)⁰ + CF₁/(1+r)¹ + ... + CFₙ/(1+r)ⁿ = 0

IRR is the value of r that satisfies this equation.
