How to use it

Use this calculator for a simple start-to-end return when there are no intermediate cash flows.

  1. Enter the positive amount invested and the non-negative ending value.
  2. Optionally enter positive years to request a compound annual growth rate.
  3. Calculate gain or loss, simple ROI, and annualised return when defined.

Worked example

Input
Invested 1,000 · returned 1,210 · 2 years
Output
Gain 210 · ROI 21% · annualised return 10%

Annualised return is CAGR, not simple ROI divided by years.

Method and definitions

  • Gain equals returned value minus investment; ROI equals gain divided by investment.
  • Annualised return is (returned/invested)^(1/years) − 1; a zero ending value produces −100%.

Limits and edge cases

  • Intermediate deposits, withdrawals, cash-flow timing, fees, tax, inflation, and risk are excluded.
  • Use an IRR or time-weighted-return method when cash flows occur during the period.
