Understanding Return Calculation
Returns are computed by compounding the annual rate over the holding period. The tool shows both the total return (growth amount) and the final value (principal + return), so you can compare scenarios by changing any input.
- Principal & Duration: Enter the starting amount and choose years, months, weeks, or days as the period unit.
- Annual Return Rate: Set the expected annual rate (%) and the tool compounds it across the full period.
- Flexible Inputs: Change any field to instantly re-project — ideal for comparing different investment options.
