To find the compounded amount, we start with the interest rate, exponentiate that over the number of periods, and multiply that figure by the starting value. So, in this case, we have 4.7% interest, or 1.047, applied to a starting balance of $22,500 over a compounding period of 6 years. Thus, the value in 6 years is $22500*(1.047^6), or $29,639.
