How buying power is worked out

Turn the yearly return of 6.5 percent into a monthly rate of 0.5417 percent by dividing by twelve. Apply that rate to the balance once a month for 360 months. Add $250 at the end of each month. Nothing else goes into the result. To see buying power, take the final balance and divide it by 1.811. That number is one plus the inflation rate of 2 percent raised to the power of 30.
