Math Problem Statement
Dr. & Mr. Wilson were delighted to find a house for sale that they loved which required them to borrow $160,000. They need to decide between a 20-year or 30-year loan. Both loans charge interest at a rate of 9.6% per year compounded monthly. 20-year Loan (a.) Find the monthly payments for the 20-year loan.
Solution
To calculate the monthly payment for the 20-year loan, we can use the formula for the monthly payment on an amortized loan:
Where:
- = monthly payment
- = loan principal (the amount borrowed) = $160,000
- = monthly interest rate (annual rate divided by 12)
- = total number of payments (loan term in years multiplied by 12)
Given:
- Annual interest rate = 9.6% = 0.096
- Loan term = 20 years
- Monthly interest rate
- Total number of payments
Let's compute the monthly payment using these values.The monthly payment for the 20-year loan would be approximately $1,501.87.

Here are 5 related questions to consider:
- How much interest will be paid over the life of the 20-year loan?
- How do monthly payments differ if the loan term is increased to 30 years?
- How does a change in interest rate affect monthly payments?
- What is the total cost of the house with interest included for the 20-year loan?
- What is the benefit of paying off a loan in 20 years versus 30 years?
Tip: Making extra payments on a loan can significantly reduce the total interest paid over the life of the loan.
