You have a goal of paying off your school loans in five years. You will graduate with a loan debt if GHS20,000 at an interest rate of 6%. How much will you need to pay each month to have the debt paid off in five years? Question 1Select one: A.
To calculate the monthly payment needed to pay off a loan, we can use the formula for the monthly payment of an amortizing loan:
\[
M = P \frac{r(1 + r)^n}{(1 + r)^n - 1}
\]
Where:
- \(M\) = monthly payment
- \(P\) = loan principal (amount borrowed)
- \(r\) = monthly interest rate (annual interest rate divided by 12)
- \(n\) = total number of payments (loan term in months)
Given:
- \(P = 20,000\) GHS
- Annual interest rate = 6% => Monthly interest rate, \(r = \frac{0.06}{12} = 0.005\)
- Loan term = 5 years => Total number of payments, \(n = 5 \times 12 = 60\)
Now, substituting the values into the formula:
\[
M = 20000 \cdot \frac{0.005(1 + 0.005)^{60}}{(1 + 0.005)^{60} - 1}
\]
Calculating \((1 + 0.005)^{60}\):
\[
(1 + 0.005)^{60} \approx 1.34885
\]
Now the formula becomes:
\[
M = 20000 \cdot \frac{0.005 \cdot 1.34885}{1.34885 - 1}
\]
Calculating the terms:
\[
M = 20000 \cdot \frac{0.00674425}{0.34885} \approx 20000 \cdot 0.019327 \approx 386.66
\]
So, the monthly payment is approximately GHS 386.66.
Thus, the correct answer is **A. GHS 386.66**.
