Loan Payment Calculator in Texas

Calculate your monthly loan payment for any loan in Texas. Based on a median household income of $80K, the 36% DTI rule allows up to $2,391/month in total debt payments. Formula shown, sources cited โ€” no account required.

Closing costs in Texas average 1.4% of the purchase price โ€” lower than the national average โ€” which translates to about $4,800 on a $342,000 home. That efficient closing structure helps buyers preserve more cash for the down payment, which at 10% runs $34,200. At the current average rate of 6.51%, monthly principal and interest on a $307,800 loan over 30 years lands near $1,950. Add the 1.80% property tax โ€” roughly $513 per month โ€” and the true housing cost jumps substantially above the mortgage payment alone. A household at the median income of $79,721 needs to keep total debt payments below about $2,860 per month to stay inside the standard 43% debt-to-income limit most lenders apply. TSAHC programs and the My First Texas Home loan can help qualifying buyers access assistance that offsets part of that upfront cash requirement. Run a loan payment calculator using Texas property data to see your full monthly obligation before you sign a purchase agreement.

How Loan Payments Work in Texas: No State Tax Means More Room

Every fixed-rate loan payment is calculated using the same amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1]. The formula produces equal monthly payments where each payment covers accrued interest first, then principal โ€” so early payments are mostly interest and later payments are mostly principal.

In Texas, borrowers earning the median $$79,721/year should cap total monthly debt (including housing) at $$2,391 (36% of $$6,643/month gross income). Exceeding this threshold makes qualifying for mortgages and other loans significantly harder.

Questions You Might Ask โ€” Loan Payment Calculator in Texas

How much loan can I afford in Texas?

With Texas's median household income of $79,721/year ($6,643/month), lenders typically allow total debt payments (including any mortgage or rent, car loans, and personal loans) of up to 36% of gross monthly income โ€” $2,391/month. If you have no other debts, you could qualify for a personal loan with a payment up to $2,391/month. At 8% over 48 months, that would finance approximately $97,932.

What is a good interest rate for a personal loan in Texas?

Personal loan rates in Texas range from 6โ€“36% depending on your credit score and lender. As of 2026, borrowers with excellent credit (750+) typically qualify for 6โ€“10% from banks and credit unions. Rates of 10โ€“20% are common for good credit (680โ€“749). Rates above 20% typically signal poor credit or high risk. Texas residents can compare rates at local credit unions, national banks, and online lenders like LightStream, SoFi, and Marcus. Credit unions in Texas often offer lower rates than banks for members in good standing.

What is the debt-to-income ratio requirement for loans in Texas?

Lenders in Texas (and nationally) use the debt-to-income (DTI) ratio to assess loan eligibility. For personal loans, most lenders prefer a DTI below 36%. For mortgages, the qualified mortgage limit is 43% DTI, though 36% is preferred. In Texas, with median household income of $79,721/year, a 36% DTI ceiling allows $2,391/month in total debt payments. Texas's cost of living index of 91.1 means housing costs may be more manageable, giving more room for other debt payments.

Should I get a fixed or variable rate loan in Texas?

For personal loans in Texas, fixed rates are almost always preferable โ€” they make budgeting predictable and protect against rate increases. Variable rate personal loans are rare; they're more common in HELOCs and student loans. For personal loans under $50,000 with terms of 2โ€“7 years, lock in a fixed rate. Since Texas has no state income tax, interest deductions (which are limited anyway for personal loans) are primarily a federal consideration.

How does Texas's cost of living affect loan affordability?

Texas's cost of living index of 91.1 (national average = 100) means that everyday expenses in Texas run about 8.900000000000006% below the national average, which can free up more income for loan repayment compared to higher-cost states. When evaluating how much to borrow, use your actual take-home pay after taxes and fixed expenses rather than gross income rules of thumb.
