The Arithmetic Return Calculator is used to calculate the Arithmetic Return of an investment, given the initial and final values of the investment.

**Initial Value** - Use this field to enter the initial value of the investment. This is the value of the investment on the day you bought it. This value must be a positive amount.

**Final Value** - Use this field to enter the final value of the investment. This is the the current value of the investment, or the value when you sold it. This value must be 0 or greater (although using 0 will always give you a result of -100%).

When entering values, you can use whatever currency you like, as long as both values are in the same currency. You don't need to use a currency symbol such as $ or £ (and doing so will cause an error).

Click the **Calculate** button to calculate the Arithmetic Return. The value, displayed as a percentage, will be shown below the button.

If either of the values has been entered incorrectly an error message will be displayed next to the field. Fix the error, then click **Calculate** again to perform the calculation.
