The question "how much house can I afford on my salary" is one of the most searched home buying questions — and one of the most incompletely answered. Most calculators spit out a maximum loan amount based on lender approval criteria. That number is not what you can comfortably afford. It is what a lender will approve. This article gives you the salary-by-salary guide to what you can genuinely afford based on the 28% rule — the figure that keeps your finances intact after buying, not just on paper at the mortgage application.
Quick Answer: Using the 28% rule (housing costs should not exceed 28% of gross monthly income) at current 6.33% mortgage rates with 20% down: $50,000 salary supports approximately $175,000–$200,000 home; $75,000 salary: $265,000–$300,000; $100,000 salary: $350,000–$380,000; $125,000 salary: $440,000–$475,000; $150,000 salary: $530,000–$570,000. Lenders may approve 30–40% higher prices — that approval ceiling is not what this guide recommends spending.
From a financial planning perspective, the salary-to-home-price relationship is the foundational calculation every buyer must run before beginning a home search — not after finding a property they want. Searching in the wrong price range wastes time and creates emotional attachment to homes you cannot comfortably afford. This builds directly on the affordability framework at how much house can I afford and the down payment detail at how much down payment you really need.
The 28% rule — salary by salary
| Annual Salary | Monthly Gross | 28% Max Housing | Home Price (20% down, 6.33%) | Home Price (10% down, 6.33%) |
|---|---|---|---|---|
| $40,000 | $3,333 | $933/mo | ~$140,000 | ~$125,000 |
| $50,000 | $4,167 | $1,167/mo | ~$175,000 | ~$155,000 |
| $60,000 | $5,000 | $1,400/mo | ~$210,000 | ~$190,000 |
| $75,000 | $6,250 | $1,750/mo | ~$265,000 | ~$240,000 |
| $100,000 | $8,333 | $2,333/mo | ~$355,000 | ~$320,000 |
| $125,000 | $10,417 | $2,917/mo | ~$445,000 | ~$400,000 |
| $150,000 | $12,500 | $3,500/mo | ~$535,000 | ~$480,000 |
| $200,000 | $16,667 | $4,667/mo | ~$715,000 | ~$645,000 |
*Estimates based on 6.33% 30-year fixed, with property taxes and insurance at approximately 1.5% of home value annually. Assumes no existing debt. Reduce figures by $20,000–$50,000 if you carry significant car loans or student debt.
How debt reduces your buying power
The table above assumes no existing debt. Every $300/month in existing debt payments (car loan, student loans, credit cards) reduces your available housing budget by that same $300/month — which translates to approximately $45,000–$55,000 less in home price at current rates. The 36% total debt rule: all debt payments combined (housing + existing) should not exceed 36% of gross monthly income. On a $100,000 salary ($8,333 gross/month): 36% = $3,000 max total debt. If $700/month already goes to a car loan and student loan minimum payments, only $2,300 remains for housing — supporting approximately $350,000 in home price rather than the $355,000 in the table above (marginal difference in this case, but significant for buyers with higher debt loads).
The dual income calculation
For dual-income households, calculate affordability using both incomes — with a critical stress test: can you afford the mortgage on one income alone if one partner loses their job, takes parental leave, or changes careers? A household with two $75,000 salaries ($150,000 combined) can afford approximately $535,000 based on the 28% combined rule. But if the mortgage requires both incomes to qualify, a single income disruption could create mortgage stress. The conservative approach: qualify on the combined income but stress-test on the lower single income. A mortgage that is manageable on $75,000 alone (approximately $265,000) is significantly less vulnerable than one requiring $150,000 combined income to sustain.
What lenders will approve versus what you should buy. At $100,000 salary with no existing debt, a lender may approve a loan where total housing costs reach $3,750/month (45% DTI). At 6.33% with 20% down, this supports a $575,000 home. The 28% rule supports $355,000. The $220,000 difference is the gap between what is approvable and what is genuinely comfortable. A $575,000 home on a $100,000 salary leaves very little for retirement savings, emergencies, home maintenance, or any income disruption. The 28% figure is where financial planners draw the line — not because 29% collapses, but because the buffer it creates makes the difference between a home that serves your life and one that consumes it.
Location adjustments — the same salary buys very different homes
The 28% rule gives you the maximum monthly housing budget. What that buys varies enormously by location. A $100,000 salary's $2,333/month housing budget buys approximately $355,000 in home value at current rates. In Indianapolis or Cleveland, $355,000 buys a 4-bedroom house in a good school district. In San Francisco or Manhattan, $355,000 does not exist as an entry-level price point. Location is where the affordability calculation meets real market reality — and why buyers in high-cost markets either accept smaller homes, longer commutes, different neighbourhoods, longer saving timelines, or the conclusion that renting is genuinely the better financial choice for their income level in that market.

Conclusion
The salary-to-home-price table in this article gives you the starting point for your home search — the price range where housing costs consume 28% or less of gross income and leave meaningful room for everything else in your financial life. Use lender pre-approval to confirm eligibility, not to set your target price. Set your target price from the 28% calculation. Then subtract $20,000–$50,000 if you carry significant existing debt. Start your home search at or below that number — not at the top of it. The best financial outcomes in homeownership come from buyers who chose a home they could comfortably afford, not the most expensive home they could technically qualify for.
Key Takeaways
- The 28% rule: housing costs (mortgage P+I + taxes + insurance + HOA) should not exceed 28% of gross monthly income. At 6.33% with 20% down: $100,000 salary supports approximately $355,000 in home price.
- Every $300/month in existing debt (car loans, student loans, credit cards) reduces your available housing budget by $300/month — approximately $45,000–$55,000 less in home price at current rates.
- Dual-income households: qualify on combined income but stress-test on the lower single income. A mortgage that requires both partners' income to sustain creates significant financial vulnerability to any income disruption.
- Lenders may approve 30–40% more than the 28% rule supports. The lender's ceiling is their risk threshold — not a recommendation for what you should spend.
- Location determines what the budget buys: $355,000 (the 28%-rule home for $100K salary) buys a 4-bedroom in Indianapolis; it buys nothing in San Francisco. The affordability calculation must meet local market reality.
- Start your home search at or below the 28% figure — not at the top of it. The financial difference between buying at 28% and buying at 40% of income is not marginal: it is the difference between financial flexibility and being house-poor for years.
Frequently Asked Questions
On a $50,000 annual salary ($4,167/month gross), the 28% rule allows approximately $1,167/month for total housing costs (mortgage principal and interest, property taxes, homeowner's insurance). At 6.33% on a 30-year fixed mortgage with 20% down and estimated taxes and insurance at 1.5% of home value annually, this supports approximately $175,000–$185,000 in home price. With 10% down and PMI added: approximately $155,000–$165,000. A lender may approve significantly more (up to $265,000 at 43% DTI with no other debt) — but that approval level leaves very little financial margin for other priorities on a $50,000 income.
On a $100,000 salary ($8,333/month gross), the 28% rule allows approximately $2,333/month for total housing costs. At 6.33% with 20% down, this supports approximately $350,000–$375,000 in home price assuming property taxes and insurance at 1.5% of home value. With existing debt of $500/month (car payment plus student loan minimum), the available housing budget reduces to approximately $1,833/month — supporting approximately $275,000–$295,000. A lender may approve up to $450,000–$480,000 at 43–45% DTI — that level leaves limited room for retirement savings, maintenance, and any income disruption on a $100,000 salary.
To buy a $300,000 home comfortably using the 28% rule with 20% down at 6.33%: the mortgage payment is approximately $1,497/month. Adding estimated taxes and insurance of approximately $375/month gives total housing cost of approximately $1,872/month. At 28% of gross income: $1,872 ÷ 0.28 = $6,686/month gross income required = approximately $80,000/year. With 10% down and PMI: slightly higher monthly cost, requiring approximately $85,000–$90,000 annual income at the 28% threshold. With significant existing debt, the required income increases further.
A $500,000 home with 20% down ($100,000 down payment) at 6.33% produces a mortgage payment of approximately $2,494/month. Adding taxes and insurance at 1.5% of home value ($625/month) gives total housing cost of approximately $3,119/month. At 28%: $3,119 ÷ 0.28 = $11,140/month gross = approximately $134,000 annual salary required under the 28% rule. With 10% down and PMI: approximately $145,000+ required. Lenders may approve buyers earning $110,000–$115,000 for a $500,000 home (at 43–45% DTI with no other debt) — but at that income level the mortgage payment will significantly strain retirement contributions and discretionary cash flow.
The 28% affordability rule uses gross income (before tax) — which is also what lenders use for DTI calculations. However, since you actually live on after-tax income, it is worth running the calculation both ways. The practical impact: a buyer earning $100,000 gross receives approximately $72,000–$78,000 after federal and state income taxes. If housing costs consume 28% of gross ($2,333/month), that represents approximately 37–38% of actual take-home pay after taxes — a more meaningful figure for monthly budgeting. This is why the 28% gross income rule produces a genuinely comfortable payment for most buyers, rather than the 43–45% lenders will approve which can consume 60%+ of after-tax income.
