Smart Mortgage Calculator helps buyers and homeowners see principal, interest, taxes, insurance, PMI, and HOA together — then dig into the scenario that matches their loan. Specialized calculators model refinance break-even, FHA upfront and annual MIP, and ARM intro vs. stress payments. State and county selectors add local tax and insurance context.
Formulas and assumptions are documented on our methodology page. Estimates are educational — confirm pricing with a licensed lender.
How a mortgage payment is built (PITI)
Most people shop a mortgage by the interest rate alone. Lenders and escrow accounts care about the full housing payment — often called PITI: principal, interest, taxes, and insurance. Private mortgage insurance (PMI) or FHA mortgage insurance premiums (MIP), plus HOA dues when they apply, sit on top of that stack. A slightly higher rate in a low-tax county can still beat a lower rate in a high-millage area once escrow is included.
Worked example (illustrative only): on a $400,000 purchase with 20% down, the loan amount is $320,000. At a 6.75% 30-year fixed rate, principal and interest alone are about $2,075 per month. Add a 1.1% effective property-tax rate (~$367/mo), $1,800/year homeowners insurance (~$150/mo), and $0 PMI because the down payment is 20%, and the full housing payment is closer to $2,590 before HOA. Drop the down payment to 5% and PMI appears; switch to FHA and MIP rules replace PMI. Our calculator lets you change those inputs and see the payment update immediately.
Principal and interest are calculated with the standard amortization formula documented on our methodology page. Taxes and insurance defaults can be refined by state and county after you press Go — they are planning estimates, not your exact mill rate or insurer quote.
Which calculator should you use?
Smart Mortgage Calculator is a toolkit. Start here for a conventional-style payment with taxes, insurance, PMI, and HOA. Open a specialized tool when the product rules change the math:
Affordability — works backward from income and debts to a payment you can carry, then to a price range.
FHA — models upfront and annual MIP and low-down-payment scenarios against county loan limits.
VA — focuses on funding-fee and $0-down payment structure for eligible borrowers.
Refinance — compares current vs new principal and interest, break-even months, and lifetime interest — not payment alone.
ARM — stress-tests an introductory payment against a higher reset-rate payment on the same balance.
The same loan amount produces different total payments across the United States because property taxes, homeowners insurance, and sometimes HOA norms vary widely. Selecting a state and county and pressing Go loads planning defaults for tax and insurance and, where data is available, FHA and conforming loan-limit context for specialized tools. That does not replace your county assessor, insurance agent, or Loan Estimate — it stops a national average from hiding a local escrow surprise.
After you apply a location, you can expand an amortization schedule and download a PDF of the payment path you just modeled. Change rate, term, or price and the schedule updates with the calculator.
What these tools are — and are not
Smart Mortgage Calculator is an educational product from Michael Hubbard / Axion Integration Services, LLC. We are not a mortgage lender, broker, or creditor, and nothing on this site is a loan offer, pre-approval, or personalized financial advice. Rate averages shown with the calculator come from public Freddie Mac / FRED series when available, with a documented fallback. Loan limits reference published HUD and FHFA figures for 2026 where we cite them.
Always compare official Loan Estimates from licensed lenders on the same day, verify taxes with local authorities, and confirm insurance with carriers that write in your ZIP code. Use our disclaimer and methodology pages if you need the full list of assumptions and limitations.
A practical workflow for first-time and repeat buyers
A useful session on this site usually looks like: (1) pick a comfortable monthly housing budget using the affordability tool or your own pay stubs; (2) model a purchase price and down payment here with taxes and insurance turned on; (3) compare FHA, VA, or conventional paths if your credit or cash-to-close situation suggests it; (4) if you already have a loan, run refinance break-even before you pay for an appraisal; and (5) read one Smart Buying guide on rates, PMI, or closing costs so the Loan Estimate does not surprise you. Save or print the amortization PDF only after the inputs match the scenario you intend to discuss with a lender.
If national headlines about rates worry you, remember that your quoted rate depends on credit, loan type, points, and lock period — and that escrow often moves the payment more than a small rate change. Use the live Freddie Mac averages on this page as context, then shop multiple Loan Estimates the same day. That combination of transparent math and local defaults is what Smart Mortgage Calculator is built for.

Texas market guide
Local tax, insurance, program, and payment context for the location you selected — county defaults refine the calculator; the guide remains state-level.
Housing market snapshot
Texas spans high-growth metros (Dallas - Fort Worth, Austin, Houston, San Antonio) and far more affordable secondary markets. No state income tax shifts more of the housing cost into property taxes and insurance. With an indicative median near $350,000, Texas sits in the middle of the national price distribution. Small rate changes move the payment more than many first-time buyers expect.
Property taxes and homestead notes
Texas's average effective property tax rate of roughly 1.60% ranks among the higher statewide averages nationally. On a median-priced home, taxes can rival or exceed the insurance line item in your payment. Texas property taxes are among the higher effective rates nationally. Homestead exemptions (general, over-65, disability) and appraisal caps for homesteads can help - file with your county appraisal district.
Homeowners insurance
Indicative average homeowners insurance around $2,400/year is elevated versus many states. Treat insurance shopping as part of your offer strategy, not an afterthought. Hail in North Texas, wind/hurricane on the Gulf Coast, and rising premiums statewide make insurance a first-class budget item. Percentage wind/hail deductibles are common.
Worked payment example
Using Texas's indicative median of $350,000, a 20% down payment of $70,000, a 6.75% rate, and local tax/insurance defaults, principal and interest is about $1,816 with a full monthly payment near $2,483 (including roughly $467 tax and $200 insurance). With only 5% down ($17,500), the same price point jumps to about $2,976 per month because the loan is larger and PMI is typically required — roughly $152 of that total.
A common comfort check is keeping total housing cost near 28% of gross income. At $2,483/month, that implies ballpark gross income around $106,403 per year before other debts. Run your real income and debts through our home affordability calculator rather than relying on this rule of thumb alone.

Common questions about estimating a mortgage payment in Texas, including local tax and insurance context.
What is the average property tax rate in Texas?
Texas's indicative average effective property tax rate is about 1.60% of home value per year. On a $350,000 home, that is roughly $5,600 annually, usually collected monthly through escrow. Your county bill can differ — and homestead programs may reduce what you owe.
How much is a typical mortgage payment in Texas?
On the indicative median of $350,000 with 20% down, local tax/insurance defaults, and a 6.75% rate, a full monthly payment is about $2,483. Your quote will differ with price, credit, loan type, and exact escrow items.
Does this calculator include Texas homeowners insurance?
Yes. We default to an indicative Texas average near $2,400 per year ($200/month). Replace it with a real quote for your address — especially if you need wind, hurricane, wildfire, or flood endorsements.
What assistance programs should Texas buyers know about?
Texas State Affordable Housing Corporation / TDHCA programs. Also explore: Local bond and DPA programs in major metros; VA loans widely used near large military installations. Program rules change — confirm eligibility with the agency or a participating lender.
