U.S. Mortgage Calculator 2026: Estimate Your Monthly Payment

A mortgage calculator helps you estimate more than the loan payment. This free U.S. tool combines principal and interest with annual property taxes, homeowners insurance, monthly PMI, and HOA dues, so you can compare a more complete housing-cost estimate before you shop.

How to use this mortgage payment calculator

1. Enter the home price you are considering.
2. Choose whether your down payment is a dollar amount or a percentage, then enter it. The loan amount updates automatically.
3. Enter the annual interest rate quoted to you and choose a 15-, 20-, or 30-year fixed loan term.
4. Add annual property taxes and homeowners insurance, plus monthly PMI or HOA dues when they apply.

The results update as you edit the fields. Start with a realistic home price and your lender’s rate estimate, then adjust the down payment or term to compare scenarios. The estimate is for planning; your lender’s Loan Estimate and closing documents determine your actual costs. For a plain-language explanation of the standardized form, see the CFPB’s Loan Estimate guide.

What your estimated monthly mortgage payment includes

Principal is the amount that reduces what you owe. Interest is the lender’s charge for borrowing. The calculator combines these into one monthly principal-and-interest amount using a standard fixed-rate amortization formula. A longer term generally lowers the required monthly principal-and-interest payment but spreads repayment over more months, which can increase total interest.

Property taxes and homeowners insurance are entered as annual amounts and divided by 12 for a monthly estimate. Your actual tax bill depends on local rates, assessed value, exemptions, and reassessments. Insurance premiums vary by location, home features, coverage, and carrier. If these costs are paid through escrow, your servicer may adjust the amount collected as bills change.

Private mortgage insurance (PMI) is a lender or insurer charge that may apply to some conventional loans when the down payment is below 20%. Rules and cancellation timing depend on the loan and servicer. Enter the monthly PMI estimate from your lender; use zero when it does not apply. HOA dues are also entered separately because communities set their own amounts and billing schedules.

Compare down payments and loan terms

A larger down payment reduces the loan principal and may reduce or avoid PMI, but it also uses more cash up front. A smaller down payment can preserve savings while increasing the amount borrowed and possibly adding PMI. Compare the monthly estimate with the cash you need for closing, moving, repairs, and an emergency reserve.

Use the 15-, 20-, and 30-year options to see the trade-off between payment size and total interest. A shorter term typically requires a larger principal-and-interest payment but pays down the balance faster. The annual amortization summary shows how the principal share generally grows over time while the interest share declines. This table assumes scheduled payments and does not model extra payments, adjustable rates, or a future refinance.

Use a full housing budget, not just the loan payment

A monthly payment estimate is one part of affordability. Budget separately for utilities, maintenance, repairs, closing costs, and any one-time assessments. Those costs are not included in the calculator. For a broader view of take-home income, compare your plans with our U.S. salary after-tax calculator.

This mortgage calculator with taxes and insurance is an educational planning tool, not a loan offer or financial, tax, or legal advice. It uses the figures you enter and does not verify a property’s tax record, insurance quote, PMI eligibility, or HOA assessment. Ask a lender, insurance professional, tax assessor, and HOA for property-specific numbers before committing.

Frequently asked questions

How is the monthly mortgage payment calculated?

The principal-and-interest portion uses the loan amount, monthly interest rate, and number of monthly payments. The calculator then adds one-twelfth of annual property tax and insurance, plus the monthly PMI and HOA amounts you provide. That makes it a monthly mortgage payment calculator for estimating recurring costs, not just the loan payment.

Does this mortgage calculator include taxes and insurance?

Yes. Enter annual property taxes and homeowners insurance in dollars. The tool divides each amount by 12 and displays it separately so you can see how it contributes to the monthly estimate.

How do I use the mortgage calculator with PMI?

Enter the monthly PMI amount supplied by your lender or use zero if PMI does not apply. PMI requirements and cancellation rules vary by loan type and circumstances, so confirm them with your lender or servicer.

Is the mortgage payment calculator an exact quote?

No. It is an estimate based on your inputs. Your actual payment can differ because of lender terms, escrow adjustments, insurance costs, taxes, PMI, and fees. Review the official Loan Estimate and closing disclosure for transaction-specific figures.

What does total loan cost mean here?

Total loan cost is the loan principal plus the interest scheduled across the selected fixed-rate term. It excludes the down payment, property taxes, insurance, PMI, HOA dues, closing costs, and any optional extra payments.
