Mortgage Calculator
After sitting across from a first-time buyer in 2021 who froze up when I tried to break down their $320,000 mortgage’s principal and interest, I realized spreadsheets and quick mental math weren’t enough to cut through the stress of home financing. I built this mortgage calculator to mirror the exact breakdowns I use with my clients—factoring in local Dallas-area tax rates and typical PMI thresholds—to turn overwhelming numbers into clear, actionable next steps. Now I pull it up in every initial consultation, because I want every buyer to walk away feeling confident, not confused, about what their dream home will actually cost each month.

How to Use This Mortgage Calculator
This calculator estimates your monthly mortgage payment including:
- Principal: The amount that goes toward paying down your loan balance

- Property Tax: Annual property taxes divided by 12 months
- Insurance: Homeowners insurance divided by 12 months
- PMI: Private Mortgage Insurance (if down payment is less than 20%)
Understanding Your Numbers
The 28/36 rule is a common guideline for home affordability:
- Your mortgage payment (PITI) should be no more than 28% of your gross monthly income
- Your total debt payments should be no more than 36% of your gross monthly income
