How Monthly Mortgage Payment Is Calculated

The monthly mortgage payment is calculated using the standard fixed-rate amortization formula. This formula takes your loan amount, divides the annual interest rate by 12 to get a monthly rate, and multiplies the loan term by 12 to get the total number of payments. The result is a fixed monthly payment that pays off both principal and interest over the entire loan term.

This formula assumes a fixed interest rate that stays the same for the entire loan term. If the interest rate changes, the payment amount would also change.

What Your Mortgage Calculation Means

Your monthly mortgage payment is the amount you would pay each month to fully repay your loan over the specified term. This payment includes both principal (the amount you borrowed) and interest (the cost of borrowing). In the early years of a mortgage, more of your payment goes toward interest. Over time, more goes toward principal. For example, on a $300,000 loan at 6.5% for 30 years, your monthly payment would be approximately $1,896. A shorter 15-year term at 6.0% would have a higher monthly payment of about $2,532 but would save you tens of thousands in interest.

Consider your budget and long-term financial goals when choosing a loan term. A longer term means lower monthly payments but more interest paid over the life of the loan.

Accuracy, Limitations & Common Mistakes of the Mortgage Calculator

How Accurate Is the Mortgage Calculator?

This calculator provides estimates based on the standard fixed-rate amortization formula used by lenders. The monthly payment estimate is generally close to what lenders would calculate for a fixed-rate mortgage. However, actual payments may differ due to rounding methods used by different lenders, the exact day your first payment is due, and other factors specific to your loan agreement.

Limitations of the Mortgage Calculator

This calculator does not include property taxes, homeowners insurance, mortgage insurance, or homeowners association fees, which are often part of actual monthly housing costs. It also assumes a fixed interest rate for the entire loan term and does not account for adjustable-rate mortgages. The calculator does not consider extra payments, prepayment penalties, or closing costs. For a complete picture of home affordability, consider all monthly housing expenses.

Common Mistakes to Avoid

• Entering the interest rate as a decimal instead of a percentage. Enter 6.5 for 6.5%, not 0.065.
• Forgetting that this calculator only shows principal and interest, not the full monthly housing payment including taxes and insurance.
• Comparing only monthly payments without considering total interest paid over the life of different loan terms.
