Aman deposits $ 14 comma 14,000 at the beginning of each year for 8 years in an account paying 4% compounded annually. he then puts the total amount on deposit in another account paying 7% compounded semiannually for another 7 years. find the final amount on deposit after the entire 15-year period.

Value of deposit after 15 years is $264,581.64

Explanation:

Given:

Amount deposited every year for 8 years = $14,000

Compound interest rate = 4%

It is an annuity as same amount is deposited every year. Using present value of annuity table to compute the value of deposits at present.

Present value of annuity factor at 4%, 8 years is 6.7327

Present value of deposits = 14,000 × 6.7327

                                           = $94,257.8

This amount is deposited another account earning 7% semi-annually. Annual rate will be 7÷2 = 3.5%

Compounding period is 15×2=30 periods

Value of deposit after 15 years =

where, P is present value of deposits that is $94,257.8

i = 0.035

n = 30

Substitute these values in the above formula:

Value of deposit after 15 years =

                                                         = 94,257.8 × 2.807

                                                         = $264,581.64

it is a i took the test.
