How Much House Can I Afford? Complete 2026 Guide
July 28, 2026
If you've typed "how much house can I afford" into Google, you've probably landed on a dozen calculators that all ask for your income and spit out a number - with no explanation of where that number actually comes from. This guide breaks down the real math lenders use, so you understand not just what you can afford, but why.
The Short Answer: The 28/36 Rule
Most US lenders use a debt-to-income (DTI) guideline called the 28/36 rule:
- 28% Rule: Your monthly housing payment (principal, interest, taxes, insurance) shouldn't exceed 28% of your gross monthly income.
- 36% Rule: Your total monthly debt, including the house payment plus car loans, credit cards, and student loans, shouldn't exceed 36% of gross income.
Some lenders stretch this to 43-50% for FHA loans with strong compensating factors, but 28/36 remains the industry-standard starting point.
Real Examples: What This Looks Like By Income
Numbers are easier to understand with real scenarios. Here's how the 28/36 rule plays out at different income levels, assuming a 7% interest rate, 30-year term, and $300/month in existing debt:
| Annual Income | Max Housing Payment | Approx. Home Price* |
|---|---|---|
| $50,000 | $1,167/mo | $155,000 - $175,000 |
| $75,000 | $1,750/mo | $240,000 - $270,000 |
| $100,000 | $2,333/mo | $320,000 - $360,000 |
| $150,000 | $3,500/mo | $490,000 - $540,000 |
*Assumes 10% down payment, 7% rate, 30-year term, 1.2% property tax, and average insurance. Your exact number will vary.
How Expensive of a Home Can I Afford? It's Not Just Income
People often ask "how expensive of a house can I afford" as if income is the only variable. In reality, four factors move the number more than people expect:
- Down payment size: Going from 5% to 20% down can increase your affordable home price by tens of thousands, since it eliminates PMI and reduces the loan amount.
- Existing debt: A $400/month car payment can reduce your home buying budget by $60,000-$80,000 compared to having no car payment at all.
- Interest rate: A 1% rate difference changes your affordable home price by roughly 10%. At 6% vs 7%, that's a real difference on a $300,000 home.
- Property location: Property tax rates range from under 0.5% in some states to over 2% in others - this alone can shift your budget by hundreds per month.
How Much Home Can We Afford as a Couple?
If you're buying with a partner, lenders combine both incomes and both debts for the DTI calculation. Two people earning $50,000 each ($100,000 combined) generally qualify for the same home price as one person earning $100,000 alone - as long as combined debts are similar. The key difference: two credit scores are considered, and lenders typically use the lower of the two scores (or a blended average, depending on the lender) to set your rate.
Zillow, Bank Calculators, and Why Numbers Differ
If you've compared a Zillow mortgage calculator to a bank's pre-qualification number, you may have noticed they don't match. Here's why:
- Zillow-style calculators often show the maximum price a formula allows, without factoring in your specific debts or verified income.
- Bank pre-qualification uses your actual pulled credit report, verified pay stubs, and their specific internal risk guidelines - which can be more conservative or more generous depending on the lender.
- Pre-approval (the strongest number) comes after full documentation review and is what sellers actually take seriously in an offer.
Use online calculators to get a ballpark figure early in your search, but always get a real pre-approval before house hunting seriously.
How Much House Payment Can I Afford? A Budget-First Approach
The 28/36 rule tells you what a lender will approve - not necessarily what fits comfortably into your life. A budget-first approach looks different:
- List your actual take-home pay after taxes.
- Subtract your current savings goals, retirement contributions, and non-housing expenses.
- See what's realistically left for a housing payment - this is often lower than what a lender would approve.
Many financial planners recommend staying below the lender's maximum, targeting 25% of take-home pay rather than 28% of gross income, to leave room for maintenance, furniture, and life's surprises.
Calculate Your Exact Number
Rules of thumb are a starting point, but your real affordability depends on your exact income, debts, down payment, and today's interest rates.

Frequently Asked Questions
How much house can I afford making $60,000 a year?
At $60,000/year with average debt, most buyers qualify for a home in the $200,000-$230,000 range with a 10% down payment at current rates, though this varies significantly based on your specific debts and credit score.
Is the 28/36 rule outdated for 2026?
No, it remains the primary guideline conventional lenders use. However, FHA and some portfolio lenders allow higher ratios (up to 50% in some cases) for borrowers with strong credit and cash reserves.
Does rent I currently pay affect how much house I can afford?
Not directly in the DTI formula, but lenders do consider your payment history. If your current rent is close to or higher than your projected mortgage payment, that's a good sign you can handle the new payment comfortably.
Should I buy at the maximum I'm approved for?
Generally no. Being approved for a certain amount doesn't mean it's comfortable to pay. Most financial advisors suggest staying 10-15% below your maximum approval to leave breathing room in your budget.
