Question

One of your customers is delinquent on his accounts payable balance. You’ve mutually agreed to a repayment schedule of $500 per month. You will charge 1.20 percent per month interest on the overdue balance.

If the current balance is $11,000, how long will it take for the account to be paid off? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

Explanation / Answer

Periods of annuity payments can be computed using formula for PV of annuity as:

PV = P x [1-(1+r)-n/r]     

PV = Present value of annuity or current balance = $ 11,000

P = Periodic cash flow = $ 500

r = Rate per period = 1.2 % or 0.012 p.m.

n = Numbers of periods

$ 11,000 = $ 500 x [1-(1 + 0.012)-n/ 0.012]

$ 11,000/$ 500 = 1-(1.012)-n/ 0.012

     22 = (1-(1.012)-n)/ 0.012

    22 x 0.012 = 1 - (1.012)-n

     0.264 = 1 - (1.012)-n

    (1.012)-n = 1 - 0.264

   (1.012)-n = 0.736

Taking log of both sides and solving for n, we get:

-n x log 1.012 = log 0.736

-n x 0.0051805125 = - 0.13312218566

n = 0.13312218566/0.0051805125

n = 25.69672125 or 25.70 months

Months for account to be paid off are 25.70 months.
