How this calculator works
Lenders commonly use the 28/36 rule: your housing payment should stay near 28% of your gross monthly income, and your total debt — housing plus everything else — should stay under your chosen back-end limit (36% by default).
A bigger down payment raises the price you can reach, because your budget caps the loan you can carry — the down payment sits on top of that maximum.
Frequently asked questions
What is the 28/36 rule?
A lending guideline: aim to spend no more than 28% of gross monthly income on housing, and no more than 36% on total debt including housing. Many programs allow higher back-end ratios (43–45%).
Does this guarantee loan approval?
No. It estimates comfortable affordability. Approval depends on your credit score, employment history, loan type, and the lender’s underwriting.
Should I borrow the maximum?
Not necessarily. This shows a ceiling, not a target. Leaving room in your budget for savings, maintenance, and emergencies is usually wise.
