How much house can I actually afford?

Income, debts, rate and down payment → the price range your budget supports under the classic 28/36 rule.

—
Max monthly payment (28% rule)
—
Max total debt payment (36%)
—
Max affordable home price
—
Comfortable range
What is the 28/36 rule?Lenders' loose ceiling: housing should cost under 28% of gross income, total debt payments under 36%. At $8k/month: $2,240 for housing, $2,880 total debt. This tool derives the max mortgage and price from those caps.
Is that my budget or the bank's?Both, roughly. You'll be denied above these ratios, but the practical number is often lower — property tax, insurance and maintenance aren't in the 28% check. The 'comfortable range' row is the realistic budget.
How is price derived?Max housing payment (includes taxes/insurance assumed ~1.25%) → solve the mortgage that fits after P&I → add the down payment. The tool walks backward from your income to a price.
Why does the rate matter so much?On a 30-year mortgage every 0.5% shifts affordability by thousands of dollars. The same $2,240 payment buys more house at 5.5% than 7.5% — the tool shows both implicitly when you move the rate.
