Question

Assume the total cost of a college education will be $184,061 when your child enters college in 19 years. You presently have $49,327 to invest. What annual rate of interest must you earn on your investment to cover the cost of your child's college education? Enter answer as 3 decimal places (e.g. 0.123)

Answer 1

Interest rate = 0.9313

Step-by-step explanation:

Future value or the cost of edcuation after 19 years = $184061

Present value, money in hand at present = $49327

Time period, n = 19

Future value = Present value (1 + r)²

184061 = 49327 (1 + r )²

(1 + r )² = 184061 ÷ 49327

(1 + r )² = 3.73

(1 + r) = √3.73

(1 + r) = 1.9313

r = 1.9313 - 1

r = 0.9313

Or Interest rate = 0.9313
