Mortgage Calculator: Estimate Your Monthly Home Payment
Estimate monthly home loan payments, calculate interest costs, compare mortgage options, and plan your home purchase with confidence.
Buying a home is one of the biggest financial decisions you'll ever make, and understanding your monthly mortgage payment is essential before signing any loan agreement.
A mortgage isn't just about the purchase price of a property. Your monthly payment depends on several factors, including the loan amount, interest rate, repayment term, property taxes, insurance, and sometimes private mortgage insurance (PMI).

What Is a Mortgage Calculator?
A Mortgage Calculator is an online financial tool that estimates your monthly home loan payment based on several important variables.
By entering your loan details, you can instantly calculate:
- Monthly mortgage payment
- Total interest paid
- Total repayment amount
- Loan payoff schedule
- Cost of borrowing over time
Whether you're buying your first home, refinancing an existing mortgage, or comparing lenders, a mortgage calculator helps you make informed decisions before committing to a loan.
How Does a Mortgage Calculator Work?
A mortgage payment is calculated using several factors:
- Home purchase price
- Down payment
- Loan amount
- Interest rate
- Loan term
- Property taxes (optional)
- Homeowners insurance (optional)
- PMI (if applicable)
The calculator combines these variables to estimate your monthly payment and total loan cost.
Example Mortgage Calculation
Imagine you purchase a home with a Home Price of $350,000, a Down Payment of 20%, a Loan Amount of $280,000, an Interest Rate of 6.25%, and a Loan Term of 30 years.
Estimated results:
- Monthly Payment: Approximately $1,724
- Total Interest Paid: Approximately $340,000
- Total Loan Cost: More than $620,000
Why Use a Mortgage Calculator?
Using a mortgage calculator helps you:
- Estimate monthly payments before buying.
- Compare different loan offers.
- Understand the long-term cost of borrowing.
- Adjust your budget based on different scenarios.
- Determine how much home you can realistically afford.
- Evaluate the impact of a larger down payment.
- Plan your financial future with greater confidence.
Instead of relying on rough estimates, you receive accurate projections within seconds.
Factors That Affect Your Mortgage Payment
Home Price
Higher property prices generally result in larger loan amounts and higher monthly payments.
Down Payment
A larger down payment reduces your loan balance and may lower your monthly payment.
Interest Rate
Even a small difference in interest rates can save—or cost—you thousands of dollars over the life of the loan. You can review current benchmark rates published by the Federal Reserve before locking in an offer.
Loan Term
Longer loan terms usually reduce monthly payments but increase total interest paid. Shorter loan terms have higher monthly payments but lower lifetime borrowing costs.
Property Taxes
Many lenders include estimated annual property taxes in your monthly mortgage payment.
Homeowners Insurance
Insurance premiums are often collected monthly along with your mortgage payment. The Consumer Financial Protection Bureau offers helpful guidance on escrow, insurance, and closing costs.
