House hunting can be stressful, but online tools can simplify the process of setting a house budget and deciding on the terms of a home loan. Our Texas mortgage calculator can provide a quick overview of your potential monthly payments and the total interest you’ll pay over the life of your loan. You simply type in a few key numbers: the home price, down payment amount, loan term, interest rate, and property tax rate. The mortgage calculator allows you to try out different scenarios to find the cost and mortgage terms that best suit your budget. Let’s get started.

Calculator Definitions

• Home price: The home price is the purchase price you have agreed to with the home seller, which may differ from the listing price or your initial offer.

• Down payment: The down payment is the amount the homebuyer pays upfront, often expressed as a percentage of the total purchase price. Buyers typically put down between 3% and 20%; payments under 20% usually result in the need for private mortgage insurance (PMI).

• Loan term: The loan term is the time you have to repay the home loan, from 10 to 30 years. A 30-year term offers lower monthly payments but results in more interest paid overall. A shorter term helps you build equity faster and pay less interest, but has higher monthly payments.

• Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. Interest rates can vary based on borrower qualifications, market trends, and the type of mortgage loan.

• Annual property tax: Property tax is levied by local governments on both land and buildings. To find a property’s tax rate, search the ZIP code or county name and “effective tax rate” or use the Texas average of 1.36%.

• Monthly payment: The monthly payment is what you would pay toward the principal and interest each month. This Texas mortgage calculator includes property taxes in the monthly payment. Some lenders will also include home insurance and, if applicable, PMI and homeowners association (HOA) dues.

• Total interest paid: The total interest paid represents the total amount of interest you will pay over the life of the loan.
