You expect that you will need to replace your furnace in 5 years at a cost of $15,729. How much must you save today in an account that pays 3.42% APR (compounded monthly) to exactly pay the $15,729 in 5 years?
We use the formula:
A=P(1+r/12)^12n
where
A=future value
P=present value
r=rate of interest
n=time period.
15729=P*(1+0.0342/12)^(12*5)
P=15729/(1+0.0342/12)^(12*5)
=15729*0.843026584
=$13259.97(Approx)
