$250 a Month at 8 Percent

Deposits total $62,000 and interest adds $95,109. The final balance is $157,109.
How the growth is worked out
The calculation runs month by month. The yearly return of 8 percent becomes a monthly rate of 0.6667 percent. Each month the balance grows by that rate and then the deposit of $250 is added. Your $2,000 start and every deposit after it keep growing for the rest of the 20 years.
