# ROI Calculator

> Calculate return on investment and the annualised rate.

To calculate return on investment, enter what you put in, what it is worth now and how long you held it. Total ROI shows the overall percentage gain, while the annualised CAGR accounts for compounding and is the figure to use when comparing investments of different lengths.

## FAQ

### Why is CAGR lower than total ROI divided by years?

Because compounding means later gains build on earlier ones. A 50% return over three years is 14.5% CAGR, not 16.7% — dividing by the number of years ignores that the base grows each year.
