🧠 How this is calculated
Maximum payment = the lower of (income ÷ 12 × housing %) and (income ÷ 12 × total-debt % − other debts). The home price is solved so that principal and interest, property tax, insurance, HOA dues and PMI (if the down payment is under 20%) equal that payment.

❓ FAQs
How much house can I afford?
Lenders compare your monthly housing payment and your total monthly debts with your gross income. This calculator uses the lower of the two limits you set (28% and 36% by default) and shows the price that fits.
Does this replace a pre-approval?
No. A lender considers credit score, assets, employment and loan type. Use this for planning and get a Loan Estimate for real numbers.
Is this financial advice?
No. The calculator shows what happens under the numbers you enter. Rates, limits and tax rules change; confirm with the provider or a licensed professional.
