Formula Explained
The mortgage payment is calculated using the standard mortgage formula:
Mortgage Payment Formula
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = 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 the loan balance each month, which is added to the principal each month until the loan is paid off.
Worked Example
Let's calculate a mortgage payment for a $120,000 loan with a 4.5% annual interest rate and a 30-year term.
- Convert the annual interest rate to a monthly rate: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal form.
- Calculate the number of payments: 30 years × 12 = 360 payments.
- Plug the values into the formula:
M = $120,000 [ 0.00375(1 + 0.00375)^360 ] / [ (1 + 0.00375)^360 - 1 ]
M ≈ $1,000.00
Your estimated monthly payment would be $1,000.00, with a total interest paid of approximately $180,000 over the life of the loan.
Frequently Asked Questions
What is a mortgage payment?
A mortgage payment is the amount you pay each month to repay your home loan. It includes principal (the amount you're paying off) and interest (the cost of borrowing the money).
How does the interest rate affect my payment?
A higher interest rate means you'll pay more in interest over the life of the loan, which increases your total payment. Conversely, a lower interest rate reduces your total payment.
Can I pay extra toward my mortgage?
Yes, paying extra toward your mortgage can reduce the principal balance faster, lower your total interest paid, and potentially save you thousands of dollars over the life of the loan.
