How to Use This Calculator
How Much Home Can I Afford? tab
The default tab. Enter your annual gross income, monthly debts, down payment, and credit score range. The calculator finds your maximum home price using the 28/36 DTI rule. Expand "More options" to adjust mortgage rate, loan term, property tax rate, insurance, and HOA.
Can I Afford This Home? tab
Have a specific home in mind? Enter the home price and your financials. Get an instant verdict — Comfortable, Stretched, or Over Budget — plus the exact income you'd need and how much more down payment would bring you within safe DTI limits.
Compare Loan Types tab

The Formula
Home affordability is determined by two ratios:
Front-end DTI = Monthly Housing Payment ÷ Monthly Gross Income
Back-end DTI = (Housing + All Debts) ÷ Monthly Gross Income
Standard limits: 28% front-end, 36% back-end
Monthly Payment (PMT):
PMT = P × [r(1+r)n] ÷ [(1+r)n − 1]
P = loan principal, r = monthly rate, n = total payments
Your front-end DTI (housing costs only) should stay at or below 28% of gross income. The back-end DTI (housing + car payments, student loans, credit cards) should stay at or below 36%. FHA loans allow higher DTIs (up to 43–50% with compensating factors).
The calculator works backwards from these limits to find the maximum home price you can afford, accounting for property tax, insurance, PMI, and HOA.
Example
Jason & Priya — First-time buyers, Austin TX
Combined income $120K, $60K saved for down payment, $800/mo in debts (car + student loans), Good credit (710). Looking at a $420K home. Texas property tax: 1.8%, no state income tax.
How Much Home Can I Afford? tab
Their budget is tighter than expected — the $420K home puts them at ~30% front-end DTI. The calculator shows they'd be comfortable at ~$396K with 28% DTI.
Compare Loan Types tab
With $60K down (15%), conventional wins despite PMI — it cancels at 78% LTV, while FHA MIP stays for the life of the loan.
