<PRE><B>Question 766418</B>
formula to use is:


fv = pv * (1 + air/c) ^ (y * c)


fv = future value
pv = present value
apr = annual percent interest rate
air = annual interest rate = apr / 100
c = number of compounding periods per year.
y = number of years
y1 = 10
y2 = 20
y3 = 30
pv = 6516.90
apr = 6
air = .06


in your problem, this is what happens:


y1 * c = 10 * 12 = 120
y2 * c = 20 * 12 = 240
y3 * c = 30 * 12 = 360


air / c = .06 / 12 = .005
1 + air / c = 1 + .005 = 1.005


your formulas become:


fv1 = 6516.90 * (1.005)^120 = 11856.83
fv2 = 6516.90 * (1.005)^240 = 21572.27
fv3 = 6516.90 * (1.005)^360 = 39248.52
