How Much House Can I Afford on a $100K Salary? (Real 2026 Math)
Six figures feels like a lot — until you see what 7% mortgage rates do to it. Here is the honest math, with a table for other salaries too.
Let’s do this like friends splitting a coffee bill: simple numbers, no fancy formulas on screen. (The formulas are hiding inside our affordability calculator if you want to play.)
Step 1: Your monthly housing budget
$100,000 a year is about $8,333 a month before taxes. The classic 28% rule says your total housing payment — mortgage, property tax, insurance and any mortgage insurance — should stay under 28% of that.
$8,333 × 28% = about $2,333 a month.
There is a second check, the 36% rule: all your debts together (house + car + student loans + cards) under 36% of income, which is $3,000. If you already pay $700 a month in other debts, your housing budget shrinks to $2,300.
Step 2: Turn $2,333 into a home price
We assumed a 30-year fixed loan at 7.25%, property tax plus insurance of about 1.6% of the home value per year, and PMI of about 0.6% a year when you put down less than 20%. Here is what fits:
| Down payment | Comfortable home price | Cash needed for down payment |
|---|---|---|
| 10% | about $295,000 | about $29,500 |
| 20% | about $344,000 | about $68,800 |
Do not forget closing costs on top, often 2% to 5% of the loan. Our closing cost estimator gives you a range.
Other salaries at a glance
| Salary | Max housing payment (28%) | Home price, 10% down | Home price, 20% down |
|---|---|---|---|
| $60,000 | $1,400 | ~$177,000 | ~$206,000 |
| $80,000 | $1,867 | ~$236,000 | ~$275,000 |
| $100,000 | $2,333 | ~$295,000 | ~$344,000 |
| $120,000 | $2,800 | ~$353,000 | ~$412,000 |
| $150,000 | $3,500 | ~$442,000 | ~$515,000 |
Assumes no other debts, 7.25% 30-year fixed rate, taxes and insurance about 1.6% of value per year, PMI about 0.6% per year under 20% down. Your area’s taxes and insurance can move these numbers a lot.
“But the lender said I could borrow way more!”
Lenders often allow total debt up to 43% to 50% of income. On $100,000, that could mean a housing payment of $3,500 or more. The bank is checking whether you are likely to pay them back. It is not checking whether you can also afford groceries, a new water heater, retirement savings and the occasional vacation.
5 ways to afford more (without being house-poor)
- Pay off a car loan or credit card before applying. Lower debts mean a bigger housing budget under the 36% rule.
- Raise your credit score. A better score can mean a lower rate, and a lower rate means more house per dollar.
- Look at FHA, VA or USDA loans if you qualify. Read our FHA requirements guide.
- Check down payment assistance programs from your state housing finance agency.
- Shop three lenders. Even a small rate difference changes your budget.
FAQ
Is the 28% rule based on gross or take-home pay?
Gross (before-tax) income. Since take-home pay is lower, also check that the payment feels okay against what actually lands in your bank account.
Can two incomes of $50k each afford the same as one $100k?
Usually yes, since lenders combine household income. But both borrowers’ debts and credit scores count too.
Does a bigger down payment always help?
It lowers your monthly payment and can remove PMI at 20%. Just keep an emergency fund after closing — draining every dollar into the down payment is risky.
