Figuring out how much house you can afford is one of the most important steps in the homebuying process. Borrow too much, and you’ll struggle with payments. Borrow too little, and you might miss out on the home you really want.
Our home affordability calculator helps you find the sweet spot — the maximum home price that fits your income, existing debts, and down payment while leaving room for comfortable living.

The 28/36 Rule Explained
The 28/36 rule is a time-tested guideline that financial advisors and lenders use to determine housing affordability:
- 28% Rule (Front-End Ratio): Your monthly housing costs — including mortgage principal, interest, property taxes, and insurance (PITI) — should not exceed 28% of your gross monthly income
- 36% Rule (Back-End Ratio): Your total monthly debt payments, including housing costs plus car loans, student loans, credit cards, and other debts, should not exceed 36% of your gross monthly income
Example: Applying the 28/36 Rule
Let’s say you earn $6,000 per month before taxes:
- Maximum housing payment (28%): $6,000 × 0.28 = $1,680/month
- Maximum total debt (36%): $6,000 × 0.36 = $2,160/month
If you have a $400 car payment, you’d have $1,760 available for housing under the 36% guideline ($2,160 – $400). In this case, the 28% housing rule would still apply since $1,680 is the lower limit.
Understanding Debt-to-Income Ratio
Your debt-to-income (DTI) ratio is the primary metric lenders use to determine how much house you can afford. It compares your monthly debt obligations to your gross monthly income.
How to Calculate Your DTI
DTI = (Total Monthly Debt Payments ÷ Gross Monthly Income) × 100
For example, if you earn $7,000 per month and have $2,100 in total monthly debt payments (including your proposed mortgage), your DTI would be 30% ($2,100 ÷ $7,000 = 0.30).
What Counts as Debt?
Lenders include these monthly payments in your DTI calculation:
- Proposed mortgage payment (principal, interest, taxes, insurance)
- Car loans and leases
- Student loans
- Credit card minimum payments
- Personal loans
- Child support and alimony
- Other mortgages or home equity loans
Lenders typically do not include:
- Utilities (electric, gas, water, internet)
- Groceries and food expenses
- Health insurance premiums
- Cell phone bills
- Subscriptions and memberships
Factors That Determine Affordability
Several factors work together to determine how much house you can afford:
1. Income
Your gross annual income (before taxes) is the starting point. Lenders verify this through pay stubs, W-2s, and tax returns. Self-employed borrowers typically need two years of tax returns.
2. Existing Debt
The more debt you carry, the less you can borrow for a mortgage. Paying off credit cards or auto loans before applying can significantly increase your buying power.
3. Down Payment
A larger down payment means borrowing less, which translates to lower monthly payments. It also affects whether you’ll pay private mortgage insurance (PMI). See our guide on buying a house with no money down if saving is a challenge.
4. Interest Rate
Interest rates dramatically affect your buying power. At 6% interest, every 1% rate increase reduces your purchasing power by roughly 10%. A rate of 5.5% versus 7% could mean the difference between affording a $350,000 home or a $400,000 home.
5. Credit Score
Your credit score affects your mortgage rate, which in turn affects how much you can borrow. A 760+ score gets you the best rates, potentially saving you $50,000+ over the life of your loan.
6. Property Taxes and Insurance
These vary significantly by location. A home in Texas (no state income tax but high property taxes of 1.6-2.5%) may have the same purchase price as one in Colorado (property taxes around 0.5%), but the Texas home would have higher monthly payments.
How Much House Can I Afford by Income Level
Here’s a quick reference for home affordability at various income levels, assuming a 6.5% interest rate, 10% down payment, moderate property taxes (1.2%), and minimal existing debt:
$50,000 Annual Income
- Conservative (28% DTI): $165,000 – $180,000
- Moderate (36% DTI): $195,000 – $210,000
- Maximum monthly payment: $1,167 – $1,500
$75,000 Annual Income
- Conservative (28% DTI): $250,000 – $270,000
- Moderate (36% DTI): $295,000 – $320,000
- Maximum monthly payment: $1,750 – $2,250
$100,000 Annual Income
- Conservative (28% DTI): $335,000 – $360,000
- Moderate (36% DTI): $395,000 – $430,000
- Maximum monthly payment: $2,333 – $3,000
$150,000 Annual Income
- Conservative (28% DTI): $500,000 – $540,000
- Moderate (36% DTI): $590,000 – $640,000
- Maximum monthly payment: $3,500 – $4,500
Note: These are estimates. Your actual affordability depends on existing debts, down payment, local taxes, and current interest rates. Use the calculator above for a personalized estimate.
Maximum DTI by Loan Type
Different loan programs have different DTI limits, which affects how much you can borrow:
Conventional Loans
- Maximum DTI: 43-50% with automated underwriting
- Typical requirements: 620+ credit score, 3-20% down payment
- Higher DTIs may require compensating factors (excellent credit, large reserves)
FHA Loans
- Maximum DTI: Up to 55% with automated underwriting; 31/43% for manual underwriting
- Typical requirements: 580+ credit score, 3.5% down payment
- More lenient DTI limits make FHA popular for first-time buyers
VA Loans
- Maximum DTI: No hard limit with automated underwriting; 41% guideline for manual
- Typical requirements: Military service, 620+ credit score (lender varies), 0% down
- VA evaluates residual income (money left after bills) rather than strict DTI
USDA Loans
- Maximum DTI: 29/41% (front-end/back-end) or up to 55% with automated approval
- Typical requirements: Rural location, income limits, 640+ credit score
- Great option for moderate-income buyers in eligible areas

Hidden Costs of Homeownership
Your mortgage payment is just the beginning. Plan for these additional costs:
Recurring Costs
- Property taxes: 0.5% to 2.5% of home value annually, depending on location
- Homeowners insurance: $1,500 to $3,500+ per year for most homes
- PMI: 0.3% to 1.5% of loan amount annually (if down payment is less than 20%)
- HOA fees: $0 to $500+ monthly for condos and planned communities
- Maintenance: Budget 1% of home value annually for repairs and upkeep
- Utilities: Often higher than renting due to larger space
One-Time Costs
- Closing costs: 2-5% of loan amount (see our guide on closing costs)
- Moving expenses: $1,000 to $5,000+
- Immediate repairs or upgrades: Varies widely
- Furniture and appliances: Budget accordingly for a larger space
Tips to Afford More House
If the calculator shows you can afford less than you hoped, here are strategies to increase your buying power:
1. Pay Down Existing Debt
Reducing credit card balances and paying off auto loans directly improves your DTI ratio. Paying off a $400/month car payment could increase your home buying budget by $50,000 or more.
2. Improve Your Credit Score
A higher credit score qualifies you for lower interest rates. Even a 0.5% rate reduction can add $25,000-$30,000 to your purchasing power.
3. Increase Your Down Payment
Saving more for a down payment reduces the amount you need to borrow and may eliminate PMI, lowering your monthly payment.
4. Consider a Less Expensive Area
Property taxes and insurance vary dramatically by location. Moving to a nearby suburb or a different neighborhood could get you more house for the same monthly payment.
5. Look at Different Loan Programs
FHA loans allow higher DTIs, which might qualify you for more. VA loans (if eligible) have no down payment requirement. Explore all your options.
6. Add a Co-Borrower
Adding a spouse’s or partner’s income can significantly increase your borrowing capacity, as long as their debt load doesn’t offset the benefit.
Frequently Asked Questions
With a $60,000 salary, you can typically afford a home in the $200,000-$250,000 range, assuming a 10% down payment, 6.5% interest rate, minimal existing debt, and a moderate DTI target of 36%. Your exact budget depends on debt, down payment, and local property costs.
At $100,000 annual income, most buyers can afford homes priced between $350,000-$430,000 with a 10% down payment at current rates. With less debt or a larger down payment, you could potentially afford up to $450,000-$500,000.
The 28/36 rule states that you should spend no more than 28% of your gross monthly income on housing costs (mortgage, taxes, insurance) and no more than 36% on total debt payments (housing plus all other debts). This guideline helps ensure you can afford your home comfortably.
Yes, spending 50% of your income on housing is generally too much and puts you at financial risk. While some lenders approve DTIs up to 50%, this leaves little room for savings, emergencies, or other expenses. Most financial advisors recommend keeping housing costs at 28-35% of income.
Yes, you can get approved for a mortgage with a 45% DTI, particularly with FHA loans (which allow up to 55% in some cases) or if you have compensating factors like excellent credit or significant cash reserves. However, this puts your budget at “aggressive” levels with limited financial flexibility.
FHA loans allow higher DTI ratios (up to 55%) and lower down payments (3.5%), which means you may qualify for more house than with a conventional loan. However, FHA loans require mortgage insurance premiums, which increase your monthly payment. Use our calculator and select a higher target DTI to see FHA affordability.
Buying at your maximum approved amount is risky. Lenders approve based on gross income, but you live on net income after taxes. A maximum-budget home leaves little cushion for emergencies, maintenance, or lifestyle expenses. Most financial advisors recommend buying 10-20% below your maximum to maintain financial flexibility.
Rental history doesn’t directly affect your affordability calculation, but it can help with mortgage approval. New credit scoring models (VantageScore 4.0 and FICO 10T) now consider on-time rent payments, potentially improving your credit score and qualifying you for better rates.
Minimum down payments range from 0% (VA and USDA loans) to 3% (some conventional loans) to 3.5% (FHA loans). However, putting down 20% eliminates PMI and significantly reduces your monthly payment. Most first-time buyers put down between 5-10%.
It depends on your situation. Paying off high-interest debt (like credit cards) usually provides a better return and improves your DTI ratio, increasing how much you can borrow. However, a larger down payment reduces your loan amount and eliminates PMI if you reach 20%. Run both scenarios through the calculator to compare.
Interest rates have a huge impact. On a $300,000 loan, the difference between 5.5% and 7.5% is about $400/month ($1,703 vs $2,098). That same $400/month at the lower rate could support roughly $60,000 more in loan amount. Use our mortgage calculator to see how different rates affect your payment.
Yes, but qualification is more complex. Lenders typically require two years of tax returns and calculate your income based on net profit (after business deductions), not gross revenue. This often results in a lower qualifying income than W-2 employees with similar earnings.
Bottom Line
Determining how much house you can afford involves balancing what lenders will approve with what you can comfortably pay. The 28/36 rule provides a solid foundation, but your personal comfort level may be higher or lower based on your priorities and lifestyle.
Use our home affordability calculator to get a personalized estimate, then get pre-approved to confirm your actual buying power. Remember, lenders approve you for a maximum — but that doesn’t mean you should spend it all.
The best home purchase is one that lets you build equity while still enjoying life, saving for retirement, and handling unexpected expenses without stress.
