How Much House Can I Afford?
Published 11/11/2025 · 3 min read · Finance calculators
A common rule is that a home should cost no more than about 3 to 5 times your gross annual income, and your total housing payment should stay under 28% of your gross monthly income. On $4,000 a month, that caps the payment near $1,120. Your down payment, other debts and the interest rate then set the actual price you can afford.

The income-multiple and 28/36 rules give you a ceiling in minutes. Here's how to work out an affordable price from your income, debts and down payment.
The income multiple rule
The quickest sanity check is a multiple of your income: lenders have long treated roughly 3 to 5 times your gross annual salary as the range a household can carry. Earn $60,000 a year and that points to a home somewhere between $180,000 and $300,000. It ignores your deposit and debts, so it is only a starting ceiling — but it tells you instantly whether a listing is in your world or a fantasy.
The 28/36 rule
Lenders look harder at your monthly cash flow through the 28/36 rule. Your housing payment — loan, taxes and insurance — should stay under 28% of gross monthly income, and all your debt payments together under 36%. On $4,000 a month, that is $1,120 for housing and $1,440 for total debt. If a car loan already eats $300, your housing room shrinks accordingly. This is usually the binding limit, not the income multiple.
Why the down payment changes everything
Two people with the same salary can afford very different homes if one has a bigger deposit. The down payment doesn't just cover part of the price — it shrinks the loan, so the monthly payment falls, and a payment within the 28% limit now stretches to a higher price. A larger deposit also often avoids extra mortgage insurance and can earn a lower interest rate, which lowers the payment again. Saving more before you buy is one of the most powerful levers you control.
Don't forget the true monthly cost
The mortgage is only part of what a home costs each month. Property taxes, home insurance, maintenance and — for a flat — condo or service charges all land on top of principal and interest. A rough rule is to budget around 1% of the home's value a year for upkeep alone. A price that looks affordable on the loan payment can quietly break the 28% rule once these are added, so include them before you decide.
