ROI Calculator

Calculate return on investment as a percentage, plus net profit and annualised return.

How it works

  • ROI ignores the time value of money — use CAGR to compare investments over different periods.
  • Annualised ROI = (1 + ROI)^(1/years) − 1, which is what you should compare across investments.
  • A negative ROI means the investment lost money.
