Peyton Holt · Answer 1

Future value (FV) = $57,908

Present value (PV) = $8,860

Number of years (n) = 18 years

Interest rate = ?

FV = PV (1 + r) n

$57,908 = $8,860 (1 + r) 18

$57,908 = $8,860 (1 + r) 18

$57,908 = (1 + r) 18

$8,860

6.535891648 = (1 + r) 18

18√6.535891648 = 1 + r

1.10993 - 1 = r

r = 0.10992 = 10.99%

Explanation:

In this case, we will apply the future value of a lump sum (single investment) formula. The present value, future value and number of years are given with the exception of interest rate. Thus, interest rate is made the subject of the formula.
