How This Calculator Works
ROI measures total percentage gain. Annualized return normalizes it to a yearly rate so you can compare investments held for different periods.
Formula
ROI = (Final − Initial) / Initial × 100%; Annualized = (Final/Initial)^(1/t) − 1
Example
Turning $10,000 into $15,000 over 3 years is a 50% ROI, or ~14.5% annualized.
Practical Use Cases
- Investment comparison
- Marketing campaign ROI
- Real estate flips
