How to Use This Calculator

Using our mortgage rate calculator is simple:

Enter the principal loan amount (the total amount you're borrowing)

Select the loan term in years
Click "Calculate" to see your estimated monthly payment

The calculator will display your monthly payment amount and the total interest paid over the life of the loan. You can also view a payment breakdown chart.

Formula Used

The calculator uses the standard mortgage payment formula:

Monthly Payment = 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 × 12)

This formula calculates the fixed monthly payment required to pay off a loan with compound interest.

Worked Example

Let's calculate a mortgage payment for a $300,000 loan at 5% annual interest over 25 years:

Principal (P) = $300,000
Annual interest rate = 5% (0.05)
Monthly interest rate (r) = 0.05/12 ≈ 0.004167
Number of payments (n) = 25 × 12 = 300

Plugging these values into the formula:

Monthly Payment = 300,000 × [0.004167(1 + 0.004167)³⁰⁰] / [(1 + 0.004167)³⁰⁰ - 1]

≈ $1,824.84 per month

Over 25 years, you would pay approximately $1,824.84 each month, with a total interest payment of about $365,700.

Interpreting Results

When you get your mortgage calculation results, consider these factors:

Monthly Payment: This is the fixed amount you'll pay each month
Total Interest: This shows how much more you'll pay in interest over the life of the loan
Amortization Schedule: The chart shows how your payments are divided between principal and interest over time

Remember that these are estimates. Your actual mortgage terms may vary based on your lender's specific requirements and any additional fees or closing costs.
