ROI Calculator

Computes the return on any investment from its cost (plus optional extra costs) and final value — as a simple percentage and, when you give a holding period, annualized for fair comparison.

Notes

  • A 50% ROI over ten years is under 4.2% a year — always annualize before comparing investments of different lengths.
  • This is an educational estimate, not financial advice; talk to a qualified adviser before making money decisions.
