How this is calculated

Max housing = min(28% income, 36% income − debts)

Max loan = PV of max housing payment at given rate & term

Comfortable price (80%) is a buffer — leaves room for taxes, insurance, and life.

FAQ

Common questions

What's the 28/36 rule?

Front-end DTI (housing payment) shouldn't exceed 28% of gross monthly income. Back-end DTI (housing + all other debt) shouldn't exceed 36%. Most conventional lenders allow up to 43%–45% back-end, but the 28/36 rule is a healthier sustainability target.

Why is my pre-approval higher than this calculator?

Lenders often pre-approve at 43%–50% DTI, especially for FHA or conventional loans with strong credit. That's the maximum you can borrow, not the maximum you should. The 28/36 rule reflects what's livable, not just what's loanable.

Should I include taxes and insurance?

Yes, for accuracy, your housing payment should include principal, interest, property taxes, insurance, and HOA (PITIA). This calculator estimates total payment from rate and term; in real underwriting, taxes and insurance can add 20%–30% on top of P+I.

How does down payment affect what I can afford?

A larger down payment lowers the loan size and the monthly payment, which lets you afford a higher purchase price within the same DTI. It also avoids PMI below 80% LTV. Trade-off: cash you put down can't fund repairs, reserves, or a second property.
