Monthly P&I Payment ($M$):
$$ M = P \frac{i(1+i)^n}{(1+i)^n – 1} $$
Total Monthly PITI:
$$ \text{PITI} = M + \frac{\text{Annual Tax}}{12} + \frac{\text{Annual Ins.}}{12} + \frac{\text{Annual PMI}}{12} $$

Variables Explanation
- Principal Loan Amount ($P$): The amount borrowed, excluding your down payment.
- $i$: Monthly Interest Rate – Annual Rate / 12 / 100.
- $n$: Total Payments – Loan Term in years $\times 12$.
- Annual Property Taxes (T): Crucial in Houston, as Texas has no state income tax and relies heavily on local property taxes.
- Annual Home Insurance (I): Must account for standard hazard plus potential windstorm/hurricane coverage in the Gulf region.

What is a Mortgage Calculator Houston?
A **mortgage calculator Houston** is a specialized version of the standard PITI calculator that emphasizes the cost components unique to the Houston-Sugar Land-The Woodlands metropolitan area. While the Principal and Interest (P&I) are determined by your loan terms, the Taxes and Insurance (TI) are heavily influenced by local Texas factors. Houston area property taxes are notoriously high—often ranging from 2.2% to 3.0% of the home’s value annually—due to the state’s lack of income tax. This significantly inflates the total monthly payment.
Furthermore, home insurance in Houston, located near the Gulf Coast, often requires specialized or separate windstorm and hurricane coverage, pushing insurance costs higher than in inland areas. This calculator provides a realistic estimate of the total PITI payment, making it an indispensable budgeting tool for anyone considering purchasing a home in Harris County or the surrounding areas.
How to Calculate a Houston Mortgage Payment (Example)
-
Gather Loan Details:
Principal Loan Amount: $\$350,000$. Rate: $6.0\%$. Term: 30 years.
-
Calculate Escrow Costs (Houston Example):
Annual Taxes: $\$8,750$ (2.5% tax rate on a typical home value). Annual Insurance: $\$2,000$. Annual PMI: $\$0$. Total Monthly Escrow = $(\$8,750 + \$2,000) / 12 = \textbf{\$900.00}$.
-
Calculate Monthly P&I:
Monthly Rate ($i$) is $0.005$. Total payments ($n$) are $360$. Using the amortization formula, the P&I payment ($M$) is $\textbf{\$2,098.43}$.
-
Determine Total PITI:
Total Monthly PITI = P&I $(\$2,098.43) + \text{Escrow} (\$900.00) = \textbf{\$2,998.43}$.
Frequently Asked Questions (FAQ)
Texas does not have a state income tax. To compensate for this, local government entities (including cities, counties, and school districts) rely heavily on property taxes to fund public services. This results in significantly higher property tax rates compared to states with income taxes.
Does this calculator include windstorm or hurricane insurance?It includes a field for “Annual Home Insurance,” which should be an accurate estimate. Homeowners in the Houston area often need standard hazard insurance plus a separate policy for windstorm/hurricane damage, which should be included in your total annual insurance input for a realistic PITI calculation.
How often do Houston property taxes change?Property values are typically reappraised annually by the Harris County Appraisal District (HCAD) or surrounding counties. While homestead exemptions limit increases for primary residences, taxes can and often do increase yearly, leading to adjustments in your monthly escrow payment.
Is a fixed-rate mortgage recommended in Houston?Fixed-rate mortgages (15-year or 30-year) are overwhelmingly popular in Texas and highly recommended for predictable budgeting, especially given the variable nature of other costs like property taxes and insurance.
