Affordability by Home Price

Home Price	Down Pmt (current)	Loan Amount	Monthly P&I	Total Pmt	Front-End Ratio

The 28/36 Rule: Most lenders use two ratios. The front-end ratio limits your monthly housing costs (P&I + tax + insurance) to 28% of gross monthly income. The back-end ratio (DTI) limits total debt payments (housing + car + student loans + credit cards) to 36% of gross income.

Max home price calculation: We find the maximum monthly P&I payment that keeps both ratios within limits, then back-calculate the home price using your interest rate, term, and down payment.

Important: Lenders may allow DTI up to 43–50% for FHA or VA loans. This calculator uses the conservative conventional standard. Your actual limit depends on credit score, loan type, and lender.

⚠️ These are estimates based on the 28/36 rule. Actual loan approval depends on credit score, employment history, loan type, and lender requirements. Consult a licensed mortgage professional before making home-buying decisions.
