How to figure out the salary you need to afford a house

Most affordability calculators run forward: you enter an income and they tell you how much house you can buy. This one runs the other way. You name the home price you want, and it finds the gross salary a lender would require to approve it. That's the version of the question most buyers actually type into a search bar: what income do I need for a $400,000 (or $500,000) home?

The math has two steps. First, build the full monthly payment, called PITI: principal and interest on the loan, plus property taxes, homeowners insurance, private mortgage insurance (PMI) if your down payment is under 20 percent, and any HOA dues. For a $400,000 home with 20 percent down at 6.75 percent over 30 years, principal and interest run about $2,075 a month, taxes and insurance add roughly $500, and there's no PMI, for a PITI near $2,575. Second, divide that payment by the 28 percent housing ratio, which puts the required gross income around $110,000 a year. Add other debts and the 36 percent back-end test can push it higher.

The 28/36 rule, explained

Lenders judge affordability with two ratios. The front-end ratio caps your housing payment at 28 percent of gross monthly income. The back-end ratio caps all your monthly debt, housing plus car loans, student loans, and credit card minimums, at 36 percent. Both use gross (pretax) income, because that's the figure on your pay stub before deductions, and it's what lenders can verify quickly.

With no other debt, the front-end ratio almost always sets the salary you need, since housing is your only tracked payment. Once you carry meaningful monthly debt, the back-end ratio can take over as the number that really limits you. The calculator flags which ratio governs with a badge, so you can tell whether trimming other debt (not just the mortgage) is what would lower the income you need.

What changes the income you need

The required salary is sensitive to a handful of inputs. Down payment is the biggest lever: a larger one shrinks the loan and, at 20 percent, removes PMI entirely, so the income needed steps down at that boundary. Interest rate moves the principal-and-interest payment directly, which is why a half-point swing can change the salary by several thousand dollars a year. Loan term matters too: stretching from 15 to 30 years lowers each monthly payment and the qualifying income, at the cost of more total interest.

Then there are escrow costs and existing debt. A high property tax rate or a pricey insurance market adds to PITI, and every extra $100 of monthly housing cost raises the required annual salary by roughly $4,300 under the 28 percent rule. Other monthly debts feed the 36 percent back-end test, so a car payment or student loan can lift the income you need even when the house itself hasn't changed.

Required salary vs. real take-home pay

Here's the catch lenders won't spell out: the salary this tool reports is gross, before a dollar of tax comes out. Your actual paycheck is smaller after federal income tax, state tax, and FICA, so a home that fits the 28/36 rule on paper can still feel tight in real life. Two people earning the same gross salary keep very different amounts depending on their state and filing status.

That's where the Salary Calculator app comes in. Take the gross figure from this page and run it through the Stub44 Salary Calculator app to see your monthly take-home after federal, state, and FICA taxes, and use saved profiles to weigh a home against the paycheck you actually bring home rather than the pretax number on a mortgage application.

Frequently Asked Questions

Common questions about salary needed to afford a house

What salary do I need to afford a $500,000 house?

Somewhere around $140,000 to $175,000 a year, and where you land depends on your down payment, interest rate, and other debts. With 20 percent down at about 6.75 percent, the full PITI payment comes to roughly $3,200 a month, and dividing by the 28 percent housing ratio puts the required gross income near $138,000. Put less than 20 percent down and PMI plus a bigger loan push the figure toward $167,000 or more. Enter your own numbers above to see what they add up to.

How much income do I need to buy a $300,000 or $400,000 home?

The required income scales with the price. Under the 28/36 rule with 20 percent down at current rates, a $300,000 home needs roughly $85,000 a year, and a $400,000 home needs roughly $110,000. Put less down and you add PMI on top of a larger loan, so the income needed climbs. Use the home-price chips above to jump straight to $300k, $400k, or $500k and read the salary the calculator returns.

What is the 28/36 rule and how does it decide the salary I need?

The 28/36 rule is the guideline most lenders use. The front-end ratio says your monthly housing payment should stay at or below 28 percent of gross monthly income. The back-end ratio says all your monthly debt (housing plus car loans, student loans, and credit cards) should stay at or below 36 percent. To find the salary you need, the calculator builds your full PITI payment, divides it by 0.28 (and the debt-inclusive figure by 0.36), then keeps whichever result is larger.

Does my down payment change the salary I need to afford a house?

Yes, in two ways. A larger down payment shrinks the loan, which lowers your principal and interest and the income you need to cover it. It also matters at the 20 percent mark: put down less than 20 percent and lenders add private mortgage insurance (PMI), which raises the monthly payment and the required salary. Hit 20 percent down and PMI drops to zero, so the income needed takes a noticeable step down at that boundary.

How do property taxes, insurance, and PMI affect the income I need?

They all fold into the monthly housing payment (PITI) that your salary is measured against, so higher escrow costs mean a higher required income. Property tax runs about 1.1 percent of home value a year on average, homeowners insurance about 0.35 to 0.5 percent, and PMI about 0.5 percent of the loan a year when your down payment is under 20 percent. A high-tax county or a small down payment can add hundreds a month, which raises the salary you need by thousands a year.

Is the salary shown before or after taxes?

Before taxes. Lenders qualify you on gross (pretax) income, so the figure this tool returns is a gross annual salary, not take-home pay. Your actual paycheck is smaller after federal tax, state tax, and FICA, which is why the same salary buys less house than it looks like it should. To see what that gross salary leaves in your pocket each month, check the take-home with the Stub44 Salary Calculator app.

How much of my income should go toward a mortgage?

A common target is 25 to 28 percent of gross monthly income for the full housing payment, and no more than 36 percent for all debt combined. Conservative budgets aim lower, around 25 percent for housing, while some lenders stretch the back-end ratio to 43 percent or higher. The affordability-rule selector above lets you switch between the conservative 28/36 rule, a strict 25/28 rule, an FHA-style 33/38 rule, and a 43 percent lender-max cap.

Can I afford a house on a lower salary with a bigger down payment or longer loan term?

Both help. A bigger down payment reduces the loan and can remove PMI, which lowers the monthly payment and the income required. A longer term (30 years instead of 15) spreads the loan over more payments, so each monthly principal-and-interest amount is smaller and the qualifying salary drops, though you pay more interest over the life of the loan. One thing to keep in mind: the required salary here does not include saving the down payment itself, which you still need in cash up front.
