If Tom invests $30,000 in a taxable corporate bond that provides a 6 percent before-tax return, how much will Tom's investment be worth in either 8 or 20 years from now when the bond matures? Assume Tom's marginal tax rate is 35 percent.
Tom's before tax investment worth in 8 years:
PV = 30,000
n = 8
r = 6%
FV = PV * (1 + r)^n
FV = 30,000 * (1 + 0.06)^8
FV = 30,000 * 1.5938480745
FV = $47,815.442235
Tom's before tax investment worth in 8 years is $47,815.442235
Tom's after tax investment worth in 8 years = Tom's before tax investment worth in 8 years is * (1 - tax rate)
Tom's after tax investment worth in 8 years = 47,815.442235 * (1 - 0.35)
Tom's after tax investment worth in 8 years = $31,080.03745275
Tom's before tax investment worth in 20 years:
PV = 30,000
n = 29
r = 6%
FV = PV * (1 + r)^n
FV = 30,000 * (1 + 0.06)^20
FV = 30,000 * 3.2071354722
FV = $96,214.064166
Tom's before tax investment worth in 20 years is $96,214.064166
Tom's after tax investment worth in 20 years = Tom's before tax investment worth in 20 years * (1 - tax rate)
Tom's after tax investment worth in 20 years = 96,214.064166 * (1 - 0.35)
Tom's after tax investment worth in 20 years = $62,539.1417079
