Free USA Home Affordability Calculator — How Much House Can You Buy?
The #1 question for American homebuyers: how much house can I afford? USA mortgage lenders use the 28/36 rule — your housing costs should not exceed 28% of gross income (front-end DTI) and total debt should not exceed 36% (back-end DTI). With the median USA household income of $77,400 and current mortgage rates around 6.5-7%, the average American household can afford approximately $300,000-$350,000 depending on debt load and down payment. This calculator uses real USA lending guidelines to determine your maximum home price and monthly payment.
🇺🇸 USA Home Affordability Guidelines
Fannie Mae and Freddie Mac — the government-sponsored enterprises that back most USA conventional mortgages — set the affordability guidelines that lenders follow. The standard 28/36 rule applies to conventional loans. FHA allows higher DTIs (31/43), making homeownership accessible to more Americans. VA loans use residual income rather than strict DTI ratios. Local USA housing market conditions also matter — affordability varies dramatically from affordable Midwest cities to expensive coastal markets.
