Illustrative: 36% DTI, 30-yr term at the selected sample rate. Not a pre-approval, quote, or financial advice.
How this estimate works
We cap your housing payment at 36% of gross monthly income minus existing monthly debts, convert that into a loan amount using a standard 30-year amortization at the rate you select, and add your down payment. It’s the same logic a lender starts with — simplified for a quick gut check.
What it doesn’t include
- Property taxes, insurance, and HOA (these lower your max in reality).
- PMI on low down payments.
- Lender-specific overlays and reserve requirements.
