A common guideline is the 28/36 rule: spend no more than 28% of your gross monthly income on housing costs and no more than 36% on total debt. For example, with a $85,000 salary, your max monthly housing cost would be about $1,983. This calculator factors in your specific debts, down payment, and interest rate for a more accurate estimate.
What is the debt-to-income (DTI) ratio?
DTI compares your monthly debt payments to your gross income. The front-end DTI includes only housing costs, while the back-end DTI includes all debts. Most lenders want front-end DTI under 28% and back-end under 36%. This calculator uses front-end DTI ratios of 25% (conservative), 28% (recommended), and 33% (stretch).
How does my credit score affect affordability?
Your credit score directly impacts your mortgage interest rate. Higher scores get lower rates, meaning lower monthly payments and more buying power. The difference between excellent (740+) and fair (580-669) credit can be over 1% in interest rate, translating to tens of thousands of dollars over the loan term.
Do I need 20% down to buy a house?
No, many loan programs allow 3-3.5% down. However, putting less than 20% down means you will likely pay Private Mortgage Insurance (PMI), which adds $50-$150+ per month depending on the loan amount. This calculator automatically includes PMI when the down payment is less than 20% of the home value.
What costs besides the mortgage should I budget for?
Beyond your mortgage payment, budget for property taxes (typically 0.5-2.5% of home value annually), homeowner's insurance ($100-300/month), maintenance (1-2% of home value per year), utilities, HOA fees if applicable, and closing costs (2-5% of loan amount at purchase).
How Much House Can I Afford?
Determining how much house you can afford is one of the most important financial decisions you will ever make. Lenders use a metric called the debt-to-income ratio (DTI) to evaluate borrowers. The widely referenced 28/36 rule states that you should spend no more than 28 percent of your gross monthly income on housing costs (the front-end ratio) and no more than 36 percent on total debt obligations including car loans, student loans, and credit cards (the back-end ratio).
For example, if your household earns $6,000 per month before taxes, your maximum housing payment under the 28 percent guideline would be $1,680. Lenders may approve you for more, but exceeding these thresholds increases the risk of becoming house-poor, where mortgage payments consume so much income that saving and discretionary spending become difficult.
This calculator applies both the conservative and maximum DTI thresholds so you can compare comfortable versus stretch scenarios side by side.
Factors That Affect Home Affordability
Credit Score
Your credit score directly influences the interest rate a lender will offer. A borrower with a 760 or higher score may qualify for rates 0.5 to 1.5 percentage points lower than someone with a 620 score. Over a 30-year mortgage, that difference can translate to tens of thousands of dollars in interest savings and a meaningfully higher affordable purchase price.
Down Payment
A larger down payment reduces the loan amount and can eliminate Private Mortgage Insurance (PMI), which typically costs 0.5 to 1 percent of the loan balance annually. Putting 20 percent down avoids PMI entirely, lowering your effective monthly payment and increasing the home price you can comfortably afford.
Interest Rates
Even small changes in mortgage rates have outsized effects. A 0.5 percent rate increase on a $400,000 loan adds roughly $120 per month, or over $43,000 in total interest over 30 years. Monitoring rate trends and locking at the right time matters.
Location and Property Taxes
Property tax rates vary significantly by state and county. In some areas taxes add 2 percent or more of the home value annually, which reduces the purchase price you can afford. Insurance premiums also vary by region, especially in disaster-prone areas.
How to Improve Your Home Affordability
Pay down existing debt. Reducing credit card balances and auto loans lowers your back-end DTI, which lets lenders approve a larger mortgage.
Boost your credit score. Dispute errors, pay bills on time, and keep credit utilization below 30 percent to improve your score before applying.
Save a larger down payment. Even moving from 5 percent to 10 percent down can eliminate thousands in PMI costs and reduce your monthly obligation.
Consider a longer term. A 30-year term has lower monthly payments than a 15-year term, increasing the price range you qualify for, though you pay more interest overall.
Shop multiple lenders. Rates and fees differ between banks, credit unions, and online lenders. Getting at least three quotes can save you thousands.
Frequently Asked Questions
How is the debt-to-income ratio calculated?
DTI is calculated by dividing your total monthly debt payments (including the projected mortgage payment) by your gross monthly income. A front-end DTI of 28 percent and a back-end DTI of 36 percent are the conventional benchmarks, though FHA loans allow ratios up to 43 percent or higher in some cases.
Should I buy the most expensive house I can qualify for?
Generally, no. Lender approval amounts represent the maximum, not the ideal. Financial advisors recommend leaving room in your budget for maintenance (about 1 percent of home value per year), emergency savings, and other financial goals like retirement contributions.
How much should I save for a down payment?
While 20 percent is ideal to avoid PMI, many programs accept as little as 3 to 3.5 percent down. FHA loans require 3.5 percent, and VA and USDA loans may require zero down for eligible borrowers. Factor closing costs (typically 2 to 5 percent of the purchase price) into your savings target as well.
Does my pre-approval amount equal what I can afford?
Pre-approval shows what a lender will lend, not what fits your budget. It does not account for your personal savings goals, lifestyle expenses, or upcoming life changes. Use this calculator alongside your pre-approval to find a comfortable range.
How do property taxes and insurance affect affordability?
Property taxes and homeowners insurance are included in your monthly PITI payment (Principal, Interest, Taxes, Insurance). In high-tax states, these costs can add $500 or more per month, significantly reducing the loan amount you can afford on a given income.

How Much House Can I Afford? A Complete Guide to Home Affordability
Buying a home is the largest financial decision most people will ever make. Understanding how much house you can truly afford goes far beyond looking at listing prices. It requires a careful analysis of your income, existing debts, savings for a down payment, and the ongoing costs of homeownership. Our free home affordability calculator above helps you determine a realistic budget based on proven lending guidelines that banks and mortgage lenders actually use.
Whether you earn $50,000 or $200,000 per year, the fundamental principles remain the same. Lenders evaluate your financial profile using specific ratios and thresholds to determine the maximum mortgage they will approve. By understanding these factors before you start house hunting, you can set realistic expectations and avoid the financial stress that comes with being house poor.
Understanding the 28/36 Rule for Mortgage Affordability
The 28/36 rule is the gold standard that most lenders use to evaluate mortgage applications. This two-part guideline establishes the maximum percentage of your gross monthly income that should go toward housing costs and total debt payments:
Front-end ratio (28%): Your total monthly housing costs, including mortgage principal and interest, property taxes, homeowner's insurance, and PMI, should not exceed 28% of your gross monthly income.
Back-end ratio (36%): Your total monthly debt obligations, including housing costs plus car payments, student loans, credit card minimums, and other recurring debts, should not exceed 36% of your gross monthly income.
For example, if your household earns $100,000 per year ($8,333 per month), your maximum housing payment should be around $2,333 (28%), and your total debt payments should stay below $3,000 (36%). Our mortgage calculator applies these ratios automatically to give you conservative, recommended, and maximum price ranges.
What Is a Debt-to-Income (DTI) Ratio and Why Does It Matter?
Your debt-to-income ratio is one of the most important numbers in the mortgage approval process. It measures the percentage of your gross monthly income that goes toward paying debts. Lenders use DTI to assess your ability to manage monthly payments and repay borrowed money.
DTI Categories:
Below 20% - Excellent. You will qualify for the best rates and highest loan amounts.
20-35% - Good. Most conventional loan programs will approve you easily.
36-43% - Acceptable. You may qualify but with less favorable terms.
44-50% - Risky. Limited options, typically FHA loans only with compensating factors.
Above 50% - Most lenders will deny your application at this level.
To lower your DTI before applying for a mortgage, focus on paying down credit card balances, eliminating car payments, and avoiding new debt. Even reducing your DTI by a few percentage points can significantly increase the home price you qualify for. Use our debt payoff calculator to create a plan for reducing your obligations before you start house shopping.
Down Payment Strategies: How Much Should You Save?
The size of your down payment directly impacts your monthly mortgage payment, the interest rate you receive, and whether you will need to pay Private Mortgage Insurance (PMI). Here is what you need to know about different down payment levels:
3-3.5% down: The minimum for conventional loans (3%) and FHA loans (3.5%). Expect higher monthly payments and mandatory mortgage insurance. Best for first-time buyers with limited savings but strong income.
5-10% down: A common middle ground. PMI is still required but your monthly payment is noticeably lower than the minimum down payment option.
20% down: The traditional benchmark. Eliminates PMI entirely, typically qualifies you for the best interest rates, and gives you immediate equity in your home.
More than 20%: Further reduces your loan amount and monthly payment. Consider whether this extra capital might earn more invested in the stock market through compound interest.
Hidden Costs of Homeownership Most Buyers Overlook
The monthly mortgage payment is just the beginning. Many first-time homebuyers are caught off guard by the true total cost of owning a home. Budget for these additional expenses when calculating how much house you can afford:
Property taxes: Typically 0.5% to 2.5% of your home's assessed value annually, varying significantly by state and county.
Homeowner's insurance: Averages $1,200 to $2,500 per year depending on location, coverage level, and home value.
Private Mortgage Insurance (PMI): Required when your down payment is less than 20%. Costs 0.3% to 1.5% of the original loan amount annually.
Maintenance and repairs: Budget 1% to 3% of the home's value annually. A $400,000 home may need $4,000 to $12,000 in annual upkeep.
HOA fees: If applicable, these can range from $200 to $800+ per month for condos and planned communities.
Closing costs: Typically 2% to 5% of the purchase price, paid at closing. On a $350,000 home, expect $7,000 to $17,500.
Utilities: Electricity, gas, water, internet, and trash collection can cost $300 to $600+ per month depending on the home size and location.
How Your Credit Score Affects Home Affordability
Your credit score has a direct impact on the mortgage interest rate you will receive, which in turn affects how much house you can afford. Even a small difference in interest rate translates to thousands of dollars over the life of a 30-year mortgage.
A borrower with a 760+ credit score might secure a rate of 6.5%, while someone with a 640 score could see rates around 8% or higher for the same loan. On a $300,000 mortgage, that 1.5% rate difference means roughly $300 more per month and over $100,000 more in total interest paid. Before shopping for a home, check your credit report, dispute any errors, pay down balances, and allow at least 6 months for improvements to take effect.
Mortgage Affordability by Income: Quick Reference
While every situation is unique, here are general estimates for how much house you can afford at different income levels, assuming a 7% interest rate, 10% down payment, and moderate existing debts:
$50,000 salary: Approximately $180,000 to $220,000 home price
$75,000 salary: Approximately $270,000 to $330,000 home price
$100,000 salary: Approximately $360,000 to $440,000 home price
$150,000 salary: Approximately $540,000 to $660,000 home price

Tips for Increasing How Much House You Can Afford
If the calculator shows a lower home price than you hoped, here are actionable strategies to increase your buying power:
Pay down existing debt: Reducing your DTI ratio is the fastest way to qualify for a larger mortgage.
Improve your credit score: A higher score means a lower interest rate, which increases your borrowing capacity.
Save a larger down payment: More cash upfront means a smaller loan and no PMI.
Consider a longer loan term: A 30-year mortgage has lower monthly payments than a 15-year, letting you qualify for more.
Look into first-time buyer programs: Many states offer down payment assistance, reduced rates, or tax credits for first-time homebuyers.
Add a co-borrower: A spouse or partner's income can significantly increase the mortgage amount you qualify for.
