How much house can you afford based on your income and debts?
Leave property tax and insurance blank for estimates based on home price.

Debt-to-Income Ratio (DTI)
0%—
Lenders typically require DTI below 43% (some accept up to 50%). Your housing costs should not exceed 28% of gross monthly income.
How is this calculated?
Your maximum affordable home price is determined by the back-end debt-to-income ratio — your total monthly debt obligations (including the new mortgage) divided by your gross monthly income.
Front-end ratio (28% rule): Housing costs (PITI) should be no more than 28% of gross monthly income
Back-end ratio (36-43% rule): All debts combined should be no more than 36-43%
PITI: Principal & Interest + Property Tax + Home Insurance (± PMI)
The calculator uses the stricter of the two ratios to determine your maximum mortgage, then adds your down payment to get the total home price.
Can I improve my buying power?
Pay down existing debt — lower credit card and auto payments directly increase affordability
Save for a larger down payment — reduces the mortgage principal and may eliminate PMI
Improve your credit score — even a 50-point increase can drop your rate by 0.25-0.5%
Consider a 15-year mortgage — higher monthly payment but much more buying power
Look for gift funds — family contributions to down payment count toward your equity
