Formula Used

Loan Payment Formula

The monthly payment (PMT) for a loan is calculated using the formula:

PMT = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount ($19,000)
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the specified term. The total interest paid is the total of all payments minus the principal amount.

Worked Example

Let's calculate a $19,000 loan at 7% annual interest over 15 years:

Convert annual rate to monthly: 7% ÷ 12 = 0.5833%
Calculate number of payments: 15 × 12 = 180
Plug values into formula:
PMT = 19000 × (0.005833(1 + 0.005833)^180) / ((1 + 0.005833)^180 - 1)
Result: Monthly payment = $142.45
Total interest paid = (142.45 × 180) - 19000 = $1,662.70

This example shows that with a 7% interest rate, you would pay $142.45 per month with $1,662.70 in total interest over 15 years.

Frequently Asked Questions

What is the difference between simple and compound interest?

Simple interest is calculated only on the original principal amount, while compound interest is calculated on the principal plus any accumulated interest from previous periods. Compound interest typically results in higher total payments over time.

How does changing the interest rate affect my payments?

A higher interest rate will increase your monthly payments and the total amount paid over the life of the loan. Conversely, a lower interest rate will reduce these amounts.

Can I pay off my loan early without penalty?

Most loans allow prepayment without penalty, but you should check your loan agreement. Paying early can save you money on interest and reduce the total cost of the loan.
