How Much House Can I Afford on a $100,000 Salary?
A $100,000 salary is a strong starting point for buying, but the right home price still depends on debt, down payment, interest rates, and local taxes. This guide walks through the 28/36 rule, rough price ranges, and how to turn a salary into a comfortable monthly payment, without the jargon.
The Quick Answer Using the 28/36 Rule
A $100,000 salary is about $8,333 per month before taxes. The classic 28/36 guideline suggests:
- 28% for housing: about $2,333 per month for mortgage, taxes, insurance, and HOA
- 36% for all debts: about $3,000 per month including housing plus car loans, student loans, and credit cards
That $2,333 figure is a planning target, not a hard limit. If you have little other debt, you may have more room. If debt is high, aim lower so buying does not crowd out savings.
Conservative, Balanced, and Stretch Ranges
Here is a plain-English way to think about monthly housing on $100,000:
| Approach | % of Gross | Monthly Housing | Best For |
|---|---|---|---|
| Conservative | 25% | ~$2,083 | Debt payoff or aggressive saving |
| Balanced (28%) | 28% | ~$2,333 | Most buyers with typical expenses |
| Stretch | 32% | ~$2,667 | Low debt, stable income |
Rough Home Price Examples at 6.5%
To turn a monthly payment into a home price, you need an interest rate, loan term, and down payment. These educational examples assume a 6.5% 30-year fixed mortgage with 20% down, looking at principal and interest only. Taxes and insurance would raise your total housing cost.
| Approach | Est. PI Payment | Loan Amount | Home Price (20% Down) |
|---|---|---|---|
| Conservative | ~$2,083 | ~$330,000 | ~$410,000 |
| Balanced | ~$2,333 | ~$370,000 | ~$460,000 |
| Stretch | ~$2,667 | ~$420,000 | ~$525,000 |
A smaller down payment usually means a larger loan, higher monthly payment, and possibly PMI. A larger down payment does the opposite. Rates also matter a lot: a lower rate can support a higher price at the same payment.

- Other monthly debts: Car loans and student loans reduce the room left under the 36% cap.
- Down payment size: More cash down lowers the loan and the payment. See our down payment guide.
- Property taxes and insurance: These can add hundreds each month, especially in high-tax areas.
- Interest rate and loan term: Small rate changes move your max price more than most people expect.
- Closing costs and reserves: Keep cash set aside so the purchase does not wipe out your emergency fund.

After-Tax Reality on $100,000
Lenders look at gross income, but you live on take-home pay. On $100,000, many people keep roughly $6,000 to $6,800 per month after federal, state, and payroll taxes, depending on location and deductions.
A $2,333 housing payment is 28% of gross, but it can feel closer to 34% to 39% of take-home. If that feels tight, the conservative range leaves more room for groceries, childcare, repairs, and saving.
Renting vs Buying on $100k
Buying is not automatically better than renting. If you may move within a few years, or if local prices are far above the payment you can handle calmly, renting can be the smarter short-term choice. Compare both paths with our rent vs buy calculator.
Frequently Asked Questions
How much house can I afford on $100k a year?
Using the 28% rule, many buyers target about $2,333 in monthly housing costs. With a 6.5% 30-year loan and 20% down, that often lines up near the mid-$400,000s before taxes and insurance, but your debts and local costs matter a lot.
What is the 28/36 rule?
Keep housing near 28% of gross income and all monthly debts near 36%. On $100,000, that is about $2,333 for housing and $3,000 for total debt payments.
Should I stretch to buy more house?
Only if your other debts are low, your income is stable, and you still have room to save. A stretch payment can work in a high-cost city, but it leaves less margin for repairs, rate changes, or job surprises.
