How this is calculated
Your housing budget is the lower of two caps: 28% of gross monthly income, or 36% of income minus your existing debt payments. From that monthly budget the calculator subtracts taxes and insurance, converts the remainder into a supportable loan at your rate and term, and adds your down payment to get the maximum price. The "comfortable" figure uses a stricter 25% housing ratio — a common rule for not being house-poor.
Frequently asked questions
What is the 28/36 rule?
Housing costs ≤ 28% of gross monthly income, total debts ≤ 36%. Most conventional lenders underwrite near these ratios (some allow up to 43–50% DTI).
Should I borrow the maximum?
Usually not. The bank's maximum ignores retirement savings, childcare, and your actual lifestyle. The 25%-rule figure leaves margin for real life.
How much should I put down?
20% avoids PMI and improves your rate, but 3–5% down is allowed on many loans. Less down = bigger loan + PMI + higher payment.
