    What is Mortgage Calculator?

    What is Mortgage Calculator?

    The Mortgage Calculator is a free online tool that estimates your monthly mortgage payment based on the home price, down payment, interest rate, loan term, property taxes, and home insurance. It gives you a clear breakdown of what you can expect to pay each month — including principal and interest, property tax, and insurance — so you can budget accurately before committing to a home purchase. All calculations update instantly as you change any input, making it easy to explore different scenarios.
    How Mortgage Calculator Works

    How Mortgage Calculator Works

    The calculator uses the standard mortgage amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where M is the monthly payment, P is the loan principal (home price minus down payment), r is the monthly interest rate (annual rate divided by 12), and n is the total number of payments (years × 12). Property tax and home insurance are divided by 12 and added to the principal and interest payment to give you the full PITI (Principal, Interest, Tax, Insurance) estimate.
    Why Use Mortgage Calculator?

    Why Use Mortgage Calculator?

    Buying a home is one of the largest financial decisions most people make, and understanding the true monthly cost is critical to making the right choice. This calculator helps you avoid overextending your budget by giving you a realistic picture of your total monthly housing cost before you start shopping. It is especially useful for comparing how different loan terms (15 vs 30 years) or down payment sizes affect your monthly obligation and total interest paid over the life of the loan.
    Tips

    Tips & Best Practices

    • 1A 20% down payment eliminates PMI and significantly reduces your monthly payment
    • 2Even a 0.5% difference in interest rate can change your payment by hundreds of dollars — shop multiple lenders
    • 3Shorter loan terms (15 years) have higher payments but save tens of thousands in interest over the loan life
    • 4Factor in HOA fees and maintenance costs on top of the calculated payment for a true budget
    • 5Use the current property tax rate for the specific county, not a national average
    Understanding Your Payment Breakdown

    Understanding Your Payment Breakdown

    Your monthly mortgage payment has multiple components. Principal is the portion that reduces your loan balance. Interest is the lender's fee for the loan — it starts high and decreases over time as you pay down the balance. Property tax is collected monthly and held in escrow to pay your annual tax bill. Home insurance (hazard insurance) protects the property and is also typically escrowed. Together, these four components make up what mortgage professionals call PITI.
    How Loan Term Affects Your Payment

    How Loan Term Affects Your Payment

    A 30-year mortgage spreads the loan over 360 payments, resulting in a lower monthly payment but significantly more total interest paid. A 15-year mortgage has higher monthly payments but typically offers a lower interest rate and you pay the loan off in half the time, saving substantial interest. A 20-year mortgage is a middle ground. As a rule of thumb, choosing a 15-year over 30-year loan at the same rate roughly doubles the monthly payment but reduces total interest by 50-60%.
