How it works
Max housing budget = min(28% of monthly income, 36% of income − existing debts); loan = budget × (1−(1+r)⁻ⁿ)/rFrequently Asked Questions
How much house can I afford on my salary?
Lenders typically allow housing costs up to 28% of gross monthly income (front-end ratio), provided all debts stay under 36% (back-end). On a $90,000 salary with no other debt, that is about $2,100/month for housing, which supports roughly a $310,000–$340,000 home at typical rates with 10% down.
Does this include property tax and insurance?
Yes — the calculator reserves about 25% of your housing budget for property taxes, homeowners insurance and PMI, and sizes the loan on the remaining 75%, which mirrors how pre-approvals work in practice.
What is the 28/36 rule?
A lending guideline: spend at most 28% of gross monthly income on housing, and at most 36% on housing plus all other debt payments (cars, cards, student loans). Many lenders stretch further, but staying inside 28/36 keeps the payment comfortable.
