Loan term: The length of your mortgage in years

Click "Calculate" to see your estimated monthly payment and other key figures. The calculator will also show you an amortization schedule chart that breaks down your payments over time.

Note

This calculator provides estimates only. Actual mortgage terms may vary based on your lender, loan type, and other factors. Always consult with a mortgage professional for personalized advice.

Formula Used

The calculator uses the standard mortgage payment 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 calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.

Worked Example

Let's calculate a mortgage payment for a $200,000 loan at 4.5% interest over 30 years:

Principal (P) = $200,000
Annual interest rate = 4.5% or 0.045
Monthly interest rate (i) = 0.045 / 12 ≈ 0.0037917
Number of payments (n) = 30 years × 12 = 360

Plugging these values into the formula:

Calculation

M = 200,000 [ 0.0037917(1 + 0.0037917)^360 ] / [ (1 + 0.0037917)^360 - 1 ]

M ≈ $1,073.64 per month

This example shows that a $200,000 mortgage at 4.5% interest over 30 years would require approximately $1,073.64 monthly payments.

Interpreting Results

When you run the calculator, you'll see several key figures:

Monthly Payment: Your regular payment amount
Total Interest: The total amount paid in interest over the life of the loan
Total Cost: The sum of the principal and total interest paid

These figures help you understand the true cost of your mortgage and how different loan terms affect your financial situation.

Tip

Consider comparing different loan terms and interest rates to find the most affordable option. Even small differences in interest rates can significantly impact your total payments over time.

Frequently Asked Questions

What is the difference between APR and interest rate?

The annual percentage rate (APR) is the total cost of borrowing, including fees and other charges, while the interest rate is the cost of borrowing without these additional costs. The APR is always higher than the interest rate.

How does a mortgage term affect my payments?

A longer mortgage term means lower monthly payments but more interest paid over time. A shorter term means higher monthly payments but less interest paid. Choose a term that fits your budget and financial goals.

What is an amortization schedule?

An amortization schedule shows how much of each payment goes toward interest and how much goes toward the principal balance. It helps you track your loan progress and see when you'll be debt-free.

Can I pay extra toward my mortgage?

Yes, paying extra principal can reduce your interest costs and pay off your loan faster. Many lenders allow prepayment without penalty. Our calculator can help you estimate the savings from extra payments.
