A^(-b) = 1 / (a^b)

examples : 4^(-3) = 1 / (4^3) = 1 / 64

2 + 4^(-2) = 2 + 1/(4^2) = 2 + 1/16 = 2 1/16

3 * 2^(-2) = 3 * 1 / (2^2) = 3 * 1/4 = 3/4

Ymorist [56]

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

We have to determine

In calculating the monthly payment for a five-year loan, what value should be used for n, the number of periods over which the loan is repaid, as it appears in the following formula?

<h3>What formula is used to calculate the monthly payment?</h3>

The value of the monthly payment is given by;

\rm P=PV\times \dfrac{i}{1-(1+i)^{-n}}

Where,

  • PV is the present value or the amount of the loan.
  • i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.
  • n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Therefore,

The value should be used for n, the number of periods over which the loan is repaid;

n = 6 years × 12 months/year = 60 months = 60 periods.

Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.
