Return on Investment (ROI) Calculator
Calculate your profit percentage and annualised return on any investment
// ROI Formula
ROI = (Return - Investment) / Investment × 100. A 44% ROI means you earned 44 cents for every dollar invested. Simple, powerful, universal.
// Annualised Return
Annualised ROI accounts for time. 44% over 3 years is ~12.9% per year. This lets you compare investments with different time horizons fairly.
// Benchmarks
S&P 500 historical average: ~10%/year. SA JSE All Share: ~11%/year. SA property: ~7-9%. If your investment beats these, you're outperforming the market.
// After Inflation
Always consider real returns (after inflation). A 10% return with 6% inflation gives a real return of only ~3.8%. SA inflation averages 5-6%.
