How Much Mortgage Can I Afford on My Salary in the US: A Practical Guide

Understanding how much mortgage you can afford on your salary in the US is the first step toward buying a home without financial strain. Lenders and financial planners use several benchmarks, but the final number depends on your income, debts, credit profile, and the size of your down payment. This guide breaks down the key rules so you can estimate your borrowing limit with confidence.

The 28/36 Rule: A Standard Starting Point

Most US lenders rely on the 28/36 rule. It suggests your monthly housing costs — principal, interest, taxes, and insurance (PITI) — should not exceed 28% of your gross monthly income. Total debt payments, including the mortgage, car loans, student loans, and credit cards, should stay under 36%.

For example, if your gross annual salary is $80,000, your monthly income is about $6,667. Under the 28% rule, your maximum housing payment would be roughly $1,867. Under the 36% rule, total debt payments should stay below $2,400.

How Lenders Calculate Your Borrowing Limit

When you apply for a mortgage, underwriters examine your debt-to-income ratio (DTI), credit score, employment history, and savings. Many conventional loans allow a DTI up to 43–50%, while FHA loans may accept higher ratios with compensating factors. A strong credit score can lower your interest rate, which directly increases how much mortgage you can afford on your salary.

Your down payment also matters. A 20% down payment removes private mortgage insurance (PMI) and reduces the loan amount. On a $400,000 home, that means $80,000 upfront. First-time buyer programs and FHA loans allow down payments as low as 3–3.5%, but expect higher monthly costs.

Estimating Your Number in Practice

Use this simple formula: take your gross monthly income, multiply by 0.28, and subtract estimated taxes, insurance, and HOA fees. The remainder is your approximate principal and interest budget. Then compare it with current mortgage rates to see the loan size you can support.

Keep in mind that how much mortgage you can afford on your salary in the US is not just a lender calculation — it is a personal budget decision. Leave room for maintenance, utilities, emergency savings, and lifestyle expenses. A mortgage that fits your bank's criteria may still feel tight if you have other financial goals.

Conclusion

Your affordable mortgage amount depends on income, debts, credit, and down payment. Start with the 28/36 rule, verify your DTI with a lender, and stress-test your budget before committing. Being conservative today protects your finances for years to come.
