How Much House Can I Afford on an $80,000 Salary?
Quick answer
On an $80,000 salary, the usual 28% guideline allows about $1,867 a month for housing. Leaving out property tax and insurance, that would support roughly a $369,000 home with 20% down at 6.5% over 30 years. Once you set aside a realistic amount for tax and insurance from that same budget, the price you can really afford falls to about $296,000, a fifth lower than the headline figure.
"How much house can I afford?" has a quick answer and a right answer, and they aren't the same number. The quick answer applies a rule of thumb to your gross salary and stops there. The right answer looks at what actually leaves your account each month, where the mortgage is only one line among several.
This guide works through the full calculation on an $80,000 salary. That figure is close to the US median household income, so the same reasoning carries over well to incomes nearby.
The two ratios lenders actually use
Conventional lenders apply two tests, not one, and a loan has to pass both. The front-end ratio limits housing costs on their own, commonly to around 28% of gross monthly income. The back-end ratio limits housing plus every other required debt payment, commonly to around 36%, with 43% often quoted as the outer limit for a Qualified Mortgage.
On $80,000 a year, gross monthly income is $6,667. The 28% front-end test allows $1,867 a month for housing. The 36% back-end test allows $2,400 for all debts together, so with $300 a month of existing car or student loan payments, it still leaves $2,100 for housing, which is more room than the front-end test gives. Here the front-end ratio is the one that limits you, at $1,867. Someone with more existing debt might find the back-end ratio bites first.
What $1,867 buys, the simple version
Treat the whole $1,867 as principal and interest, borrow at 6.5% over 30 years, and work backwards: that payment supports a loan of about $295,000. Add a 20% down payment and the price it points to is about $369,000.
That's where most online calculators stop, and it's the figure that gets passed around in casual advice. It's also wrong, because nobody's mortgage payment is just principal and interest.
The Home Affordability Calculator gives you the ceiling this rule points to. Then the Mortgage Calculator, with its optional tax, insurance and PMI fields, shows the real monthly cost of a particular price.
What the same budget buys once tax and insurance are included
In the US, the full monthly cost of a home is PITI: principal, interest, taxes and insurance, plus PMI if you put down less than 20%, and any HOA fee. All of it has to fit inside the same $1,867, not only the principal and interest.
Find the price where principal and interest, a typical property tax bill of 1.1% of the price a year, and $1,200 a year of insurance together come to exactly $1,867 a month, and the affordable price drops to about $296,000. That's 20% lower than the principal-and-interest answer. At that price, the monthly split is about $1,496 of principal and interest, $271 of property tax and $100 of insurance.
So treat the principal-and-interest figure as the very top of your range, not the number to take house-hunting.
- The gap between the simple answer and the real one grows with local property tax. On the same salary, a county charging 2.5% a year leaves you a noticeably lower price than one charging 0.5% a year.
- PMI takes a further bite if your down payment is under 20%, and it doesn't show up in the principal-and-interest figure at all.
- HOA fees, common on condos and managed developments, come out of the same budget and are easy to overlook when you're comparing listings.
Checking the answer against the ratios
The affordability ceiling and your debt-to-income ratio are two views of the same limit, and it's worth checking both rather than trusting a single calculation. Put the same $6,667 monthly income, the $1,867 PITI figure and any existing debts into the DTI Calculator, and it will show your front-end and back-end percentages against the 28/36/43 guidelines. That can catch a mistake the affordability figure on its own wouldn't reveal.
Frequently Asked Questions
Is $80,000 enough to buy a house?
⌄
In most US markets, yes, in the roughly $270,000-$300,000 range this guide arrives at once property tax and insurance are included. Local prices vary hugely, though, and the same salary buys far less in an expensive city.
Should I use the 28% or 36% rule?
⌄
Whichever is stricter for you. Work out both: 28% of your gross income for housing alone, and 36% of your gross income minus your other monthly debts. The lower of the two is your real ceiling.
Does this include closing costs?
⌄
No. Closing costs (typically 2-5% of the loan amount) are cash you need once, when you buy, separate from the monthly affordability worked out here.
What if I have a large down payment saved?
⌄
A bigger down payment means a smaller loan, and it removes PMI once you reach 20%. Both raise the price you can afford on the same monthly budget, and you can try it in the Home Affordability Calculator.
