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
  • r = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years multiplied by 12)

This formula accounts for the interest on both the original principal and the accumulated interest over the life of the loan, providing an accurate estimate of your monthly payments.

Worked Example

Let's calculate the monthly payment for a $200,000 loan with a 4.5% annual interest rate over 30 years.

  1. Convert the annual interest rate to a monthly rate: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal form.
  2. Calculate the number of payments: 30 years × 12 = 360 payments.
  3. Plug the values into the formula:

    PMT = $200,000 × (0.00375(1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1)

  4. The calculation results in a monthly payment of approximately $1,143.25.

This means you would pay about $1,143.25 each month for 30 years, with a total interest payment of approximately $343,930 and a total repayment amount of $543,930.

Frequently Asked Questions

What is the difference between APR and interest rate?
The interest rate is the cost of borrowing, while the APR (Annual Percentage Rate) includes additional fees and costs associated with the loan. The APR is typically higher than the interest rate.
How does loan term affect my monthly payments?
A longer loan term means lower monthly payments but more total interest paid over the life of the loan. A shorter loan term means higher monthly payments but less total interest paid.
Can I pay extra toward my loan without penalty?
Yes, most loans allow you to make additional payments without penalty. Paying extra can help you pay off your loan faster and save on interest.
What happens if I miss a loan payment?
Missing a loan payment can result in late fees, a higher interest rate, or damage to your credit score. It's important to make your payments on time to avoid these consequences.
How can I lower my loan payments?
You can lower your loan payments by making larger down payments, extending the loan term, or refinancing to a lower interest rate.
