How we calculate return rate
Total return = (final value − initial value) / initial value × 100%. CAGR = (final value / initial value)^(1 / years) − 1. Profit = final value − initial value. Multiple = final value / initial value. Results are nominal — inflation and capital gains tax are not included.
Example: PLN 10,000 → PLN 15,000 over 5 years
Initial investment: PLN 10,000, value after 5 years: PLN 15,000. Total return = 50%, CAGR = 8.45% per year, profit = PLN 5,000, return multiple = 1.5x. This means the capital grew by 8.45% on average each year.
