If you invest $8,700 per period for the following number of periods, how much would you have: Use Appendix C for an approximate answer, but calculate your final answer using the formula and financial calculator methods.
a. |
In 14 years at 7 percent? (Do not round intermediate calculations. Round your final answer to 2 decimal places.)

a) If you invest $8700 per year for 14 years at 7%, you will have:
Since the cash invested per year is same, we can also add up the compounding factor and the multiply it with the sum invested.
= 8700[(1+0.07)1+(1+0.07)2+(1+0.07)3+(1+0.07)4+(1+0.07)5+(1+0.07)6+(1+0.07)7+ (1+0.07)8+ (1+0.07)9+(1+0.07)10+(1+0.07)11+(1+0.07)12+(1+0.07)13+(1+0.07)1+(1+0.07)14]
= 8700 [ 1.07+1.1449+1.225+1.31+1.42+1.50+1.60+1.71+1.83+1.96+2.10+2.25+2.41+2.58]
= 8700 ( 24.12 ) = $209830.38 approx.
b) If you invest $8700 per year for 25 years at 7%:
Future value= 8700[(1+0.07)1+(1+0.07)2+(1+0.07)3+(1+0.07)4+(1+0.07)5+(1+0.07)6+(1+0.07)7+ (1+0.07)8+ (1+0.07)9+(1+0.07)10+(1+0.07)11+(1+0.07)12+(1+0.07)13+(1+0.07)14+(1+0.07)15+ (1+0.07)16+(1+0.07)17+(1+0.07)18+(1+0.07)19+(1+0.07)20+(1+0.07)21+(1+0.07)22+(1+0.07)23+ (1+0.07)24+(1+0.07)25]
=8700[1.07+1.1449+1.225+1.31+1.42+1.50+1.60+1.71+1.83+1.96+2.10+2.25+2.41+2.58+2.76+ 2.95+3.16+ 3.38+3.62+3.87+4.14+4.43+4.74+5.07+5.42]
= 8700 ( 67.65) = $588554.13 approx
