Short answer: with a $100,000 salary and no other debts, a comfortable home price is about $300,000 to $370,000, with a total housing payment around $2,333 a month. A lender may approve you for considerably more, up to roughly $480,000 in this example, but that's a very different budget.
How it's calculated
$100,000 a year is about $8,333 a month before taxes. With the conservative 28/36 guideline:
- Housing costs up to 28%: $2,333 a month.
- All debts including housing up to 36%: $3,000 a month, which leaves about $667 for other debts before your budget shrinks.
Home price by down payment
| Down payment | Approx. home price | Cash for down payment | Principal & interest |
|---|---|---|---|
| 5% | $302,000 | $15,100 | $1,812 |
| 10% | $316,000 | $31,600 | $1,800 |
| 20% | $370,000 | $73,900 | $1,869 |
Assumptions unless noted: 30-year fixed at an illustrative 6.5%, property tax 1.1% of price per year, homeowners insurance $1,500 per year, no HOA, PMI estimated at 0.5% per year when the down payment is under 20%, and no other debts. Figures are rounded.
Comfortable vs. approved
Many lenders will approve debt-to-income ratios well above 36%. Here's how the same $100,000 income looks under different limits, with 20% down:
| Ratio limits | Housing payment | Approx. home price |
|---|---|---|
| Conservative (28% / 36%) | $2,333 | $370,000 |
| Moderate (31% / 43%) | $2,583 | $412,000 |
| Aggressive (36% / 45%) | $3,000 | $481,000 |
The aggressive budget buys about $111,000 more house, but costs $667 more every month. On a $100,000 salary, take-home pay after taxes, health insurance, and a 401(k) contribution is often somewhere around $5,600 to $6,300 a month, depending on your state and benefits. A $3,000 housing payment would be roughly half of it. That's approved, but it leaves little room for saving, retirement, childcare, or repairs.
A practical rule: let the lender tell you your maximum, and let your own budget decide your target. The affordability calculator lets you switch between these limits.

Lifestyle creep and the house
At six figures, buyers often stretch for a bigger home because the approval number is there. The risk is that the mortgage crowds out goals that compound over time. For example, $667 a month invested for 30 years at a 7% average return grows to roughly $800,000. See our compound interest calculator. That doesn't mean buying the smaller house is always right, but the true cost of the extra house includes what that money could have become.
How other debts change it
| Other monthly debts | Housing payment allowed | Approx. price (20% down) |
|---|---|---|
| $0 – $667 | $2,333 | $370,000 |
| $1,200 | $1,800 | $280,000 |
| $1,500 | $1,500 | $230,000 |
Higher earners often carry larger student loans, such as from graduate or professional school, and more expensive car payments. A $1,200 monthly total, for example $700 in student loans plus a $500 car payment, cuts the comfortable budget by $90,000.
Should you consider a 15-year loan?
At 28% of income, a 15-year mortgage at an illustrative 5.75% supports a home price of about $292,000 with 20% down. That's less house than the 30-year budget of $370,000, but you'd own it outright in 15 years and pay far less interest. See 15- vs. 30-year mortgage and pay off early or invest.
Cash to close
For a $370,000 home with 20% down, you'd need about $74,000 for the down payment plus roughly $9,000 in closing costs: around $83,000. If you'd rather keep more savings invested or in an emergency fund, putting 10% down is common at this income. Your credit score will largely determine the PMI cost. See what PMI costs.
Next steps
- Decide your comfortable monthly payment from your take-home pay, not just the ratio.
- Get pre-approved by several lenders and compare APRs.
- Test real listings, with their actual taxes and HOA dues, in the mortgage calculator.
Frequently asked questions
Can I afford a $500,000 house on $100,000 a year?
Only with a stretch. With 20% down at 6.5%, a $500,000 home costs about $3,110 a month including taxes and insurance, about 37% of gross income. Some lenders approve ratios like that, but it would take roughly half of a typical take-home paycheck at this income.
What is the 3x salary rule for buying a house?
An older rule of thumb says to spend no more than about three times your annual income on a home. At current rates, the 28% guideline works out to roughly 3.7 times income with 20% down, and less with a smaller down payment, so the two rules land in a similar range.
How much should I put down on a $100,000 salary?
There's no single right answer. 20% avoids PMI and gives you the lowest payment. 10% keeps more cash available for emergencies and investing, at the cost of PMI until you reach 20% equity. Many buyers at this income choose 10% to 15% and prepay later.
