Our calculation utilizes industry standard mortgage qualification mathematics enforced by major US lenders and backed by consumer guidelines.

What is the 28/36 rule in home affordability?
The 28/36 rule is an established personal finance guideline stating that your household should spend a maximum of 28% of gross monthly income on total housing expenses (principal, interest, taxes, insurance) and no more than 36% on total debt obligations combined (housing plus car loans, student loans, and credit cards).
Does this calculator include taxes and insurance (PITI)?
Yes! A proper affordability assessment must evaluate PITI (Principal, Interest, Taxes, and Insurance). Our tool allocates estimated national averages (1.2% property tax and 0.35% homeowners insurance) out of your allowable monthly housing payment before computing the principal loan amount you qualify for.
How does my debt-to-income (DTI) ratio affect my purchasing power?
Your debt-to-income ratio (DTI) directly throttles how much a bank will lend you. If you carry heavy auto loans or student loans, lenders will reduce your approved mortgage payment so your total monthly debt burdens do not exceed supervisory thresholds like 43%.
Should I always borrow the maximum amount shown by the calculator?
No! Borrowing at your absolute upper limit leaves zero breathing room for unexpected household emergencies, rising property assessments, or maintenance costs. Most prudent homeowners aim to purchase well below their mathematical limit.
