What is the method for calculating the difference in accumulated value within a specified time period?

edit

The method for calculating the difference in accumulated value within a specified time period is as follows:

1. Determine the starting value of the investment or account.

2. Determine the ending value of the investment or account at the end of the specified time period.

3. Subtract the starting value from the ending value to find the difference in accumulated value.

For example, if an investment account starts with $10,000 and after a year it has grown to $12,500, the difference in accumulated value over that period would be $2,500.
