House Payment Calculator Texas

Buying a home in Texas means weighing some of the highest property tax rates in the country against the advantage of no state income tax, and the monthly payment on a Texas mortgage reflects that trade-off every single month. A House Payment Calculator Texas gives you a fast, realistic estimate of the principal-and-interest portion of that payment from just three numbers: the home price, your down payment, and the interest rate.

This page explains how Texas house payments are put together, walks through the exact math the calculator uses, and shows two fully worked examples with real numbers so you can sanity-check every figure. Whether you are buying in Houston, Dallas, Austin, or San Antonio, the method below will help you budget with confidence before you ever talk to a lender.

What Is a House Payment Calculator Texas?

A house payment calculator built for Texas takes your home price, subtracts your down payment to find the loan amount, and then applies the standard amortization formula over a 30-year fixed term to compute the monthly principal-and-interest payment. It also totals the interest you will pay over the life of the loan and the all-in cost of the purchase including your down payment.

Texas buyers need this estimate more than most because the state's property taxes are among the steepest in the nation, averaging roughly 1.6 to 1.8 percent of assessed value per year depending on the county. While the calculator below focuses on principal and interest, the article explains how to layer Texas property taxes, homeowner's insurance, and any HOA dues on top so your budget reflects the true monthly outlay.

Texas also offers meaningful help to first-time buyers through programs like those run by the Texas State Affordable Housing Corporation (TSAHC), which provides down payment assistance and mortgage credit certificates. Knowing your baseline principal-and-interest payment first makes it far easier to evaluate whether those programs actually improve your monthly picture.

How the Texas House Payment Math Works

The calculator converts your annual interest rate into a monthly rate by dividing by 12, then applies the amortization formula: monthly payment equals the loan amount times the monthly rate times one plus the monthly rate raised to 360, divided by that same quantity minus one. For a 30-year fixed loan there are always 360 monthly payments.

Early in the loan, most of each payment goes to interest rather than principal, because interest is charged on the full outstanding balance. Over time the balance shrinks, the interest slice shrinks with it, and more of every payment attacks the principal. This is why the total interest on a 30-year Texas mortgage can exceed the original loan amount at higher rates.

The two companion figures complete the picture. Total interest paid is the monthly payment times 360 minus the loan amount, showing the true long-run cost of borrowing. Total cost including the down payment adds your upfront cash back in, which is the number to compare against renting over the same period.

How to Use This Calculator

Using the calculator takes less than a minute. Enter realistic Texas numbers and read the three results as a set, not in isolation.

1. Enter the home price, for example the list price of a house in the Dallas suburbs.
2. Enter your down payment in dollars. Twenty percent avoids private mortgage insurance; Texas assistance programs can help if you have less.
3. Enter the annual interest rate you were quoted, or a rate you are shopping for.
4. Press Calculate to see the monthly payment, total interest, and total cost.
5. Add your county's estimated property tax and insurance to the monthly payment for the full Texas monthly housing cost.

Worked Example 1: A $350,000 Home Near Austin

Suppose you buy a home in the Austin area for $350,000.00 with $70,000.00 down and a 30-year fixed rate of 6.50%. The loan amount is $350,000.00 minus $70,000.00, which equals $280,000.00.

The monthly rate is 6.5 divided by 1,200, or about 0.005417. Plugging the loan amount into the amortization formula over 360 payments gives a monthly principal-and-interest payment of $1,769.79. That is the core number your lender will quote, before taxes and insurance.

Over 360 payments you will pay $1,769.79 times 360, equal to $637,124.57 in total payments. Subtract the $280,000.00 loan and the total interest comes to $357,124.57. Add your $70,000.00 down payment back and the total cost of the home is $707,124.57, which shows how much borrowing really costs at this rate.

In Texas you would then add property tax. At a typical Travis County effective rate near 1.8 percent, annual tax on a $350,000 home is about $6,300, or $525 per month on top of the $1,769.79 payment, plus insurance. This is why Texas buyers must always budget beyond principal and interest.

Try the what-if that matters most in Texas: raise the rate by half a point and watch the total interest jump by tens of thousands, then raise the down payment to 25 percent and watch PMI disappear from your mental budget. The calculator rewards this kind of play because every scenario uses the same transparent formula.

Worked Example 2: A $275,000 Starter Home in San Antonio

Now consider a starter home in San Antonio priced at $275,000.00 with a 10 percent down payment of $27,500.00 and a rate of 7.00%. The loan amount is $247,500.00.

The monthly rate is 7.0 divided by 1,200, or about 0.005833. The amortization formula gives a monthly payment of $1,646.62. Because the rate is half a point higher than the first example and the down payment is smaller, the payment per borrowed dollar is noticeably larger.

Total interest over the 30 years is $1,646.62 times 360 minus $247,500.00, which equals $345,284.52. Notice that the interest is larger than the original loan, a common surprise for first-time buyers. Every extra half point of rate on a 30-year loan adds tens of thousands in lifetime interest.

If this buyer later refinances to 6 percent after building equity, the payment would drop substantially. The calculator makes that what-if comparison instant: change only the rate field and compare the two monthly payments side by side.

Another useful test is the five-year view: multiply the monthly payment by 60 and compare it against five years of renting a comparable home. In most Texas markets the ownership math wins once appreciation and principal paydown are included, but the calculator's total-cost figure keeps the comparison honest.

Texas Property Taxes and Your True Monthly Payment

Texas has no state income tax, but it funds local government largely through property taxes, and the median effective rate sits near 1.6 percent with many urban counties above 1.8 percent. On a $350,000 home that is $5,600 to $6,300 per year, or roughly $470 to $525 per month, escrowed by your lender and added to every mortgage payment.

Texas does offer a homestead exemption that removes at least $100,000 of value from school-district taxation for a primary residence, plus extra exemptions for homeowners over 65 and disabled veterans. Filing for the homestead exemption is free and is one of the highest-return paperwork tasks a Texas homeowner can do.

When lenders pre-approve you, they use the full PITI payment, principal, interest, taxes, and insurance, against your income. A calculator that shows principal and interest is step one; step two is calling your county appraisal district for the real tax figure so the payment you budget is the payment you will actually make.

Down Payments, PMI, and Texas Assistance Programs

A 20 percent down payment remains the gold standard because it avoids private mortgage insurance (PMI), which typically costs 0.5 to 1 percent of the loan per year. On a $280,000 loan that is $1,400 to $2,800 annually, or $117 to $233 added to each monthly payment until you reach 20 percent equity.

If 20 percent is out of reach, Texas buyers have options beyond standard low-down-payment loans. TSAHC offers down payment assistance as grants or deferred loans, and a mortgage credit certificate can turn part of your mortgage interest into a federal tax credit every year you live in the home.

Run the calculator twice, once with your actual down payment and once with a 20 percent down payment, and compare the monthly payments. The difference, including avoided PMI, tells you exactly what saving a larger down payment is worth in monthly cash flow.

How to Build Your Full Texas Monthly Payment Estimate

Start with the calculator's principal-and-interest figure, then add property tax. Find your county's effective tax rate through the county appraisal district website, multiply it by the purchase price, and divide by 12. On a $350,000 home at 1.8 percent, that is $6,300 a year or $525 a month, and it is usually the largest add-on.

Next add homeowner's insurance. Texas premiums average higher than the national median because of hail, wind, and hurricane exposure along the Gulf Coast. Get a real quote early, because insurance in coastal counties can exceed $3,000 a year, adding $250 or more monthly. Inland areas like Dallas-Fort Worth run meaningfully cheaper.

Finally, add HOA dues if the neighborhood has them and PMI if your down payment is under 20 percent. Sum all five components and you have the true monthly housing cost to test against the 28 percent affordability guideline. Buyers who skip this build-up routinely underestimate their payment by 30 percent or more.

Texas First-Time Buyer Programs Worth Knowing

The Texas State Affordable Housing Corporation offers several paths for first-time buyers. Its down payment assistance can come as a grant or a deferred second loan, and it pairs with conventional, FHA, and VA first mortgages. Income and purchase-price limits apply, and a homebuyer education course is typically required.

The mortgage credit certificate (MCC) deserves special attention: it converts a portion of your annual mortgage interest into a dollar-for-dollar federal tax credit, up to $2,000 per year, for as long as you live in the home and keep the mortgage. Unlike a deduction, a credit reduces your tax bill directly, which effectively lowers your monthly cost of borrowing.

Many Texas cities and counties run their own assistance programs with additional grants, so check local housing finance agencies too. Stack a state program with a local one and the combined help can cover the entire down payment, though you will still need cash for closing costs and reserves.

7 Tips for Texas Home Buyers

1. File your homestead exemption immediately. It is free, and it can cut hundreds off your annual school tax bill.
2. Get quotes from at least three Texas lenders. Rates and fees vary widely, and even an eighth of a point matters over 30 years.
3. Budget the full PITI payment. Principal and interest is only part of the Texas monthly cost; taxes and insurance are the rest.
4. Check the flood zone. Parts of Houston and the Gulf Coast require flood insurance, which can add significantly to monthly costs.
5. Ask about TSAHC programs. Down payment assistance can move your purchase timeline up by years.
6. Lock your rate in writing. A verbal quote is not a lock; get the lock confirmation with the expiration date.
7. Keep an emergency fund after closing. Aim for three to six months of the full housing payment, not just principal and interest.
8. Compare insurance quotes early. Texas premiums vary wildly by county and carrier; the cheapest quote can save $1,000-plus yearly.
9. Check flood maps before offering. FEMA flood zone status determines whether costly flood insurance is mandatory.
10. Model a rate buydown. Builder incentives and seller credits can buy your rate down for the first years; run the math before accepting.

Frequently Asked Questions

1. How much is the monthly payment on a $350,000 house in Texas?

With 20 percent down ($70,000) and a 6.5 percent 30-year fixed rate, the principal-and-interest payment is about $1,769.79 per month. Add Texas property tax and homeowner's insurance, often $500 to $800 combined, for the full monthly cost. For the most accurate figure, pull your county's current tax rate and a real insurance quote, since those two add-ons vary more than the loan math itself.

2. Why are Texas property taxes so high?

Texas has no state income tax, so counties, cities, and school districts rely heavily on property taxes for revenue. Effective rates commonly run 1.6 to 1.8 percent of market value, among the highest in the United States.

3. What is the Texas homestead exemption?

It is a constitutional provision that exempts at least $100,000 of your primary residence's value from school-district property taxes, with additional exemptions for seniors and disabled veterans. You must apply through your county appraisal district.

4. How much do I need for a down payment in Texas?

Conventional loans allow as little as 3 to 5 percent down, FHA loans 3.5 percent, and VA and USDA loans zero percent for eligible buyers. Twenty percent avoids PMI, but assistance programs can bridge the gap.

5. What credit score do I need for a Texas mortgage?

Conventional loans generally want 620 or higher, FHA loans can go down to 580 with 3.5 percent down, and the best rates typically require 740 or above. Texas assistance programs follow the same underlying loan guidelines.

6. Does the calculator include property taxes?

No. It computes principal and interest only, which is the part determined by the loan itself. Add your county's property tax and insurance separately for the complete monthly payment.

7. What is PMI and when do I pay it?

Private mortgage insurance protects the lender when your down payment is under 20 percent. It typically costs 0.5 to 1 percent of the loan amount per year and drops off once you reach 20 percent equity on a conventional loan.

8. Are closing costs higher in Texas?

Texas closing costs run roughly 2 to 5 percent of the purchase price, similar to national averages, but title insurance rates are regulated by the state, which keeps that line item predictable.

9. What is TSAHC?

The Texas State Affordable Housing Corporation is a nonprofit that offers down payment assistance, affordable mortgage options, and mortgage credit certificates to qualifying Texas homebuyers, especially first-time buyers.

10. Should I choose a 15-year or 30-year mortgage in Texas?

A 15-year loan has a higher payment but a much lower rate and far less total interest. A 30-year loan keeps payments lower and preserves cash flow. Many Texas buyers take the 30-year and make extra principal payments when they can.

11. How does the homestead exemption affect my payment?

It lowers your taxable value for school taxes, which lowers the tax portion escrowed into your monthly payment. The principal-and-interest portion is unchanged.

12. Can I buy a house in Texas with no down payment?

Yes, through VA loans for eligible veterans and USDA loans in qualifying rural areas, both of which allow zero down. Some assistance programs can also cover the down payment on conventional and FHA loans.

13. What is an escrow account?

It is an account your lender uses to collect one-twelfth of your annual property tax and insurance bills with each mortgage payment, then pays those bills for you. Most Texas mortgages with less than 20 percent down require escrow.

14. How do Texas mortgage rates compare nationally?

Texas rates track national averages closely since mortgages are priced in national markets. Local competition among Texas lenders can still produce meaningful differences, so shopping multiple quotes pays off.

15. When should I refinance my Texas mortgage?

Consider refinancing when rates drop at least 0.75 to 1 percent below your current rate, when you can remove PMI after gaining equity, or when switching from an adjustable to a fixed rate improves your stability. Compare closing costs against monthly savings first.

CONCLUSION

A Texas house payment is built from three loan numbers, home price, down payment, and rate, and then shaped by some of the highest property taxes in the country. The calculator on this page handles the loan math precisely: a $350,000 purchase with 20 percent down at 6.5 percent costs about $1,769.79 a month in principal and interest, with roughly $357,124.57 of lifetime interest.

Use that baseline, add your county's real tax and insurance figures, file your homestead exemption, and shop at least three lenders before you commit. Do that, and the monthly payment you sign up for will be one you chose deliberately, not one that surprised you at the closing table.

Texas rewards prepared buyers: the homestead exemption, assistance programs, and competitive lender market all favor those who do the homework. Build the full payment estimate, file the exemption, and let the calculator's baseline keep every quote honest.
