A common rule of thumb is that you can afford a home priced at about 3 to 4 times your annual income. On a $75,000 salary that points to roughly $225,000 to $300,000, assuming a standard down payment and no heavy existing debt. The more precise way to find your number is the 28/36 rule, which caps housing at 28% of gross monthly income and total debt at 36%.
This guide shows how those two checks work, gives worked figures for incomes from $50,000 to $150,000, and explains what pushes your number up or down. For the exact payment at today's rate, plug a price into the Mortgage Calculator.
The 28/36 Rule, Explained
Lenders rarely decide affordability from the sticker price alone. They look at two ratios against your gross monthly income, which is your pay before taxes.
- The front-end ratio caps total housing cost at 28% of gross monthly income. Housing here means principal, interest, property tax, and insurance, often shortened to PITI.
- The back-end ratio caps all monthly debt at 36% of gross monthly income. That adds car loans, student loans, and minimum credit card payments on top of housing.
For example, on a $75,000 salary your gross monthly income is $6,250. The 28% front-end limit is $1,750 for housing, and the 36% back-end limit is $2,250 for all debt combined. If you already pay $400 a month toward a car and student loans, the back-end rule leaves $1,850 for housing, so the front-end limit of $1,750 is the one that binds.
The smaller of the two limits is your real ceiling. People with no other debt are usually held back by the 28% housing cap, while people with car or student loan payments often hit the 36% total-debt cap first.
How Much House by Income
The table below applies the 28% housing cap to common salaries, then translates it into an approximate home price. The price range uses the 3-to-4-times-income rule of thumb, which already bakes in a typical down payment and a moderate interest rate.
- $50,000 a year: $4,167 gross monthly, about $1,167 for housing, home price near $150,000 to $200,000
- $75,000 a year: $6,250 gross monthly, about $1,750 for housing, home price near $225,000 to $300,000
- $100,000 a year: $8,333 gross monthly, about $2,333 for housing, home price near $300,000 to $400,000
- $125,000 a year: $10,417 gross monthly, about $2,917 for housing, home price near $375,000 to $500,000
- $150,000 a year: $12,500 gross monthly, about $3,500 for housing, home price near $450,000 to $600,000
There is a rough pattern here: every extra $25,000 of salary adds about $75,000 to $100,000 of buying power. The ranges are wide on purpose, because the interest rate and your down payment move the result more than most buyers expect.
To see your own take-home alongside the gross figure, the Paycheck Calculator shows what actually lands in your account after taxes, which is the money that has to cover the payment in real life.
What Changes Your Number
Two buyers with the same salary can afford very different homes. These factors explain the gap.
Existing debt
Every monthly payment you already owe eats into the 36% back-end limit. A $700 car payment on a $75,000 salary leaves only $1,550 of the $2,250 debt ceiling for housing, below the $1,750 front-end limit, so it becomes the binding cap. Clearing high-payment debt before you shop is often the fastest way to raise your price range. The Debt Payoff Calculator helps you plan which balances to clear first.
Property tax and insurance
The 28% cap covers full PITI, not just the loan. In a high-tax county, taxes and insurance can eat $500 or more of your monthly housing budget, leaving less for principal and interest and lowering the price you can support. Two identical incomes in different states can land $50,000 apart on price for this reason alone.
Credit score
Your score does not change the 28/36 ratios, but it changes the interest rate you are offered, which changes how much house a given payment buys. A stronger score can mean a meaningfully lower rate, and even a small rate difference shifts your affordable price by tens of thousands of dollars.
Down Payment and Interest Rate
These two levers move your number the most, so they deserve their own look.
A larger down payment lowers the loan amount, so the same monthly budget supports a higher purchase price. It can also push you past 20% down, which removes private mortgage insurance and frees up part of your monthly payment for principal and interest. As an example, going from 10% to 20% down on a $300,000 home both shrinks the loan and drops the PMI line, which together can free up well over $100 a month.
The interest rate works in the opposite direction. When rates are high, more of each payment goes to interest, so a fixed monthly budget buys a smaller loan. This is why the rule of thumb says 3 times income in a high-rate market and closer to 4 times when rates are low. The practical step is to fix a comfortable monthly payment first, then use the Mortgage Calculator to find the loan that payment supports at the rate you are quoted.
A safe habit is to shop below your maximum. Approval tells you the lender's ceiling, not the payment that leaves room for savings, repairs, and the rest of your life. Many buyers target the 28% housing figure or a little under it, then treat anything left as breathing room.
Putting It Together
To estimate your own number in three steps:
- Multiply your gross monthly income by 0.28 to get your housing ceiling, and by 0.36 to get your total-debt ceiling.
- Subtract your existing monthly debt payments from the 36% figure, then take the smaller of that result and the 28% figure as your real housing budget.
- Enter a home price in the Mortgage Calculator and adjust until the monthly payment matches that budget at your quoted rate, down payment, and local tax estimate.
That gives a grounded price range rather than a single guess, and it adapts as rates and your finances change. Browse the Finance hub for the down payment, loan, and payoff tools that fill in the rest of the picture.
Important Note
This article provides educational estimates of home affordability. It is not lending, tax, or financial advice. The amount you can actually borrow depends on your full financial profile, the lender's underwriting, local taxes and insurance, and current interest rates, so confirm the figures with a qualified mortgage professional before making an offer.
