Introduction
This mortgage calculator shows what a home loan may cost you each month. Type in the home price, your down payment, the loan term, and your ZIP code. The tool then gives you a full monthly payment estimate.
Your payment is more than just the loan. It also includes property taxes, homeowners insurance, PMI (if your down payment is under 20%), and HOA dues. This calculator adds all of them up, so you see the real number.
You also get:
- Your loan-to-value (LTV) ratio and whether PMI applies
- A housing debt-to-income (DTI) estimate if you add your income
- Total interest, taxes, and insurance paid over the life of the loan
- A full year-by-year or month-by-month payment schedule
- Step-by-step math so you can see how each number was found
Change any number and the results update right away. Use it to compare a 15-year loan to a 30-year loan, test a bigger down payment, or see how a small rate change moves your payment. It helps you plan before you talk to a lender.
How to use our Mortgage Calculator
Enter the home price, your down payment, the loan term, your ZIP code, and your tax and insurance costs. The calculator shows your total monthly mortgage payment, a full breakdown of principal, interest, taxes, insurance, PMI and HOA, your LTV and DTI ratios, lifetime costs, and a year‑by‑year amortization schedule.
Home Purchase Price: Type the price of the home you want to buy. This is the base for your loan, taxes and closing cost estimates. Not sure what price range fits your budget? Start with the Home Affordability Calculator.
Down Payment (amount): Type the cash you plan to pay up front in dollars. The percent field updates on its own.
Down Payment (percent): Or type your down payment as a percent of the price. Under 20% adds PMI to your monthly payment.
Loan Amount: You do not fill this in. It is the home price minus your down payment.
Loan Term & Type: Pick a fixed loan (10, 15, 20 or 30 years) or an ARM (5/6, 7/6 or 10/6). Fixed loans keep the same rate. ARMs can change after the fixed years end. To weigh two offers side by side, try the Mortgage Comparison Calculator.
Property ZIP Code: Enter the 5‑digit ZIP code of the home. This sets your estimated local mortgage rate, property tax rate and insurance cost.
Interest Rate: We fill this in for you. Change it if you want to test a different rate. Click "Reset to estimated rate" to go back. To see the fee-adjusted cost of a rate, use the APR Calculator.
Annual Property Tax Rate: Enter your yearly tax rate as a percent of the home price. The monthly amount updates on its own.
Property Tax (monthly): Or enter your monthly tax bill in dollars if you already know it.
Homeowners Insurance (annual): Enter what you pay for home insurance each year.
Homeowners Insurance (monthly): Or enter the monthly amount. Both fields stay in sync.
HOA Dues (monthly): Enter your monthly HOA fee. Use 0 if the home has no HOA.
Annual Gross Household Income: Optional. Enter your pre‑tax yearly income for everyone on the loan to see your housing debt‑to‑income ratio. Leave it blank to skip it. If you only know your hourly wage, the Annual Income Calculator can convert it.

What a Mortgage Payment Is Made Of
A mortgage is a loan you use to buy a home. You pay it back in monthly payments over many years. Most people think a mortgage payment is just the loan, but it is really five smaller costs added together.
- Principal — the part that pays down what you borrowed.
- Interest — what the lender charges you to borrow the money. See the lifetime total with the Mortgage Interest Calculator.
- Property taxes — what your city or county charges each year for owning the home.
- Homeowners insurance — protects your home from fire, storms, and other damage.
- PMI and HOA dues — extra costs that only some buyers pay.
People often call the first four costs PITI. Together they make your total monthly housing cost, which you can also model with the PITI Calculator.
Down Payment and Loan Amount
Your down payment is the cash you pay up front. The rest is your loan. If a home costs $300,000 and you put down $60,000, your loan is $240,000. A bigger down payment means a smaller loan, a smaller monthly payment, and less interest over time. The Down Payment Calculator shows how long it takes to save a target amount, and the Savings Goal Calculator helps you build a plan.
Loan-to-Value (LTV) and PMI
Loan-to-value compares your loan to the home price. A $240,000 loan on a $300,000 home is 80% LTV. If your LTV is over 80% (a down payment under 20%), lenders usually add private mortgage insurance, or PMI. PMI protects the lender, not you. It costs about 0.30% to 1.10% of your loan each year. PMI usually stops once your balance drops to 78% of the home price. Check your own numbers with the LTV Calculator and the PMI Calculator. Low-down-payment buyers may also want to compare an FHA loan, a VA loan, or a USDA loan.
Fixed Rate vs. Adjustable Rate (ARM)
A fixed-rate loan keeps the same interest rate and the same principal and interest payment for the whole term. A 30-year fixed loan has 360 payments. Shorter terms like 15 years cost more each month but save a lot of interest.
An ARM starts with a lower fixed rate for a set number of years. A 5/6 ARM is fixed for 5 years, then the rate can change every 6 months. Your payment can go up or down after that. ARMs have caps that limit how high the rate can go. If rates drop later, the Refinance Calculator can show whether switching makes sense.
Debt-to-Income (DTI)
Lenders look at how much of your income goes to housing. A common rule is to keep your housing payment at or under 28% of your gross monthly income. Many lenders stop at about 36% for housing plus other debts. Lower is safer and easier to get approved. Run the full picture with the DTI Calculator, and if other balances are holding you back, the Debt Payoff Calculator can help you clear them first.
How Amortization Works
Amortization is the schedule that splits each payment between interest and principal. In the early years, most of your money goes to interest. Over time, more goes to principal. At some point, the total principal you have paid passes the total interest. That is when you start building equity faster. Adding extra to each payment speeds this up — see the Mortgage Extra Payment Calculator, the Biweekly Mortgage Calculator, or the Mortgage Payoff Calculator. You can track equity growth with the Home Equity Calculator.
Other Costs to Plan For
Closing costs usually run 2% to 5% of the home price and are due when you buy — estimate yours with the Closing Cost Calculator. Your APR is a bit higher than your interest rate because it includes lender fees. Taxes, insurance, and HOA dues also tend to rise over the years, so your real payment may grow even with a fixed rate. Before you commit, it also helps to compare buying against renting using the Rent vs Buy Calculator and to budget the move itself with the Moving Cost Calculator.
