Calculate net gain and return percentage from an initial cost and a final value. Optionally compare an annualized rate over a chosen number of years.

## How to use it

1. Enter the numbers, dates or units you want to compare.
2. Choose the calculation options and calculate.
3. Review the result together with the assumptions shown.

## Example

Compare an investment costing 10000 with a final value of 12500 over two years.
