Yearly return (annualized)

How to work out ROI

  1. Enter the amount invested, with fees and other costs.
  2. Enter the amount returned, or what it is worth now.
  3. Add the years held to see the yearly return.

ROI and yearly return

ROI is the gain divided by what you put in: 50,000 that became 68,000 is a gain of 18,000, an ROI of 36%.

ROI ignores time, so the calculator also gives the annualized return: the yearly rate that grows the investment to the same amount in the same time. 36% over 3 years is 10.8% a year, not 12%, because returns compound.

Good to know

  • Count every cost in the amount invested (fees, taxes paid, repairs for a property) for an honest ROI.
  • A loss shows as a negative ROI.
  • Use the CAGR Calculator to find the end value at a given yearly rate.

Frequently asked questions

Why is the yearly return lower than ROI divided by the years?

Because growth compounds: each year's gain also grows in the following years, so a smaller yearly rate is enough to reach the same total.
