How buying power is worked out

The calculation runs month by month. The yearly return of 6.5 percent becomes a monthly rate of 0.5417 percent. Each month the balance grows by that rate and then the deposit of $250 is added. Your $15,000 start and every deposit after it keep growing for the rest of the 10 years. Two rates are at work. Your money grows at 6.5 percent a year while prices rise at 2 percent. The calculator divides the final balance by the price growth over 10 years to show its buying power.
