How much house can I afford on my salary?
Lenders commonly look at two limits: housing costs near 28% of gross monthly income and total monthly debts near 36%, with some loans allowing up to 43% or more. On $100,000 a year, gross income is about $8,333 a month, so 28% is roughly $2,333 for principal, interest, taxes, insurance, and PMI.
Your home price from that budget depends on the interest rate, down payment, property taxes, and other debts. A higher down payment or lower rate raises the price you can afford, and a car loan or student debt lowers it.
How much mortgage can I borrow?
You will often see a rule of thumb of three to five times your annual income, but the real limit is your debt-to-income ratio, credit score, and down payment. Enter your income, monthly debts, rate, and down payment above to see a loan amount that fits typical lender limits.
How much house can I afford?
“How much house can I afford” and mortgage affordability calculator are among the highest-intent searches in U.S. real estate. Lenders look at gross income, recurring debts, credit, and down payment, not just your salary, to set a limit.
Our affordability workflow will translate income and debts into a suggested price range using DTI ratios you can adjust. That helps you shop with confidence before you get pre-approved.
Understanding debt-to-income (DTI)
Back-end DTI compares all monthly debt payments plus housing to gross income. Front-end DTI looks at housing alone. Many conventional loans use 43% back-end as a guideline, while stricter budgets target 36% or lower.
Use this calculator to see how paying off a car loan or increasing your down payment changes the home price you can support, without guessing.
