About this calculator
Mortgage lenders qualify borrowers using debt-to-income ratios: your total housing payment (principal, interest, taxes, insurance) generally shouldn't exceed 28% of gross monthly income, and your total debt payments including housing shouldn't exceed 36%. This calculator applies both caps, backs out the lower resulting monthly housing budget, and converts that into an estimated maximum loan amount and home price at your interest rate and down payment.

FAQ
How much house can I afford?
On $95,000 income with $400 in other monthly debt, a $40,000 down payment, and a 6.5% rate, the 28/36 rule caps your housing payment around $2,020/month, which supports roughly a $335,000-$345,000 home price.
What is the 28/36 rule?
It's the standard lender guideline: housing costs at or below 28% of gross monthly income, and total debt (housing plus car loans, student loans, credit cards) at or below 36%.
Does this include property taxes and insurance?
Yes — the calculator estimates taxes and insurance as a percentage of home value and folds them into your housing payment cap alongside principal and interest.
Why is my affordable price lower than my bank's pre-approval?
Banks sometimes stretch to 43-45% back-end DTI on strong credit files, which raises the number but also raises your financial risk if income dips or rates reset on an ARM.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
