Home Affordability Calculator 2026
As a general rule, you can afford a home priced at 3-5x your gross annual income. With a $75,000 salary, zero debts, and a 20% down payment, you can typically afford a home between $225,000 and $375,000. Lenders prefer your total housing costs stay below 28% of gross monthly income.
Max Home Price = (Monthly Income × 0.28 - Monthly Debts) ÷ Monthly Payment Factor × Loan Amount + Down Payment
Buying a home is the largest financial decision most Americans will ever make. Our Home Affordability Calculator uses the same debt-to-income ratios and qualification criteria that mortgage lenders apply in 2026 to show you exactly how much house you can afford. Simply enter your household income, existing debts, down payment, and preferred loan terms to get a personalized affordability estimate.
According to the National Association of Realtors, the median existing-home price in the U.S. reached $396,900 in early 2026. Understanding your budget before you start house hunting prevents wasted time viewing homes outside your price range and protects you from overextending financially.
What This Means
Your estimated maximum home price is based on the standard 28/36 rule used by most conventional mortgage lenders. The front-end ratio (28%) limits your housing expenses — including principal, interest, taxes, and insurance (PITI) — to 28% of your gross monthly income. The back-end ratio (36%) caps your total debt payments at 36% of gross income. FHA loans may allow higher ratios (up to 31/43), potentially increasing your purchasing power. Always get pre-approved by a lender for the most accurate figure.

How to Use the Home Affordability Calculator
Follow these steps to determine your maximum affordable home price:
- Enter your gross annual income. Include all pre-tax household income: salary, bonuses, freelance income, rental income, alimony, and investment returns. If you are buying with a partner, combine both incomes.
- Enter your monthly debts. Include minimum payments on car loans, student loans, credit cards, personal loans, and child support. Do not include utilities, groceries, or subscriptions — lenders only count debts that appear on your credit report.
- Enter your down payment. The amount you have saved (or plan to save) for a down payment. A 20% down payment eliminates PMI, but many programs accept 3-5% down.
- Select your loan term. 30-year fixed is the most common. 15-year fixed offers lower interest rates but higher monthly payments.
- Review your results. The calculator shows your maximum home price, estimated monthly payment breakdown, and how much home you can afford at different interest rates.
The 28/36 Rule Explained
The 28/36 rule is the gold standard used by conventional mortgage lenders to determine how much you can borrow:
Front-End Ratio: 28%
Your total monthly housing costs (mortgage principal + interest + property taxes + homeowner's insurance + PMI + HOA fees) should not exceed 28% of your gross monthly income.
Example: If your gross monthly income is $7,000, your maximum housing payment is $7,000 × 0.28 = $1,960/month.
Back-End Ratio: 36%
Your total monthly debt payments (housing costs + car payment + student loans + credit cards + other debts) should not exceed 36% of your gross monthly income.
Example: With $7,000 gross monthly income and $500 in existing monthly debts, your total available for housing is ($7,000 × 0.36) - $500 = $2,020/month. In this case, the back-end ratio is the binding constraint.
| Loan Type | Max Front-End DTI | Max Back-End DTI |
|---|---|---|
| Conventional | 28% | 36-45% |
| FHA | 31% | 43% |
| VA | None (guideline 41%) | 41% |
| USDA | 29% | 41% |
Home Affordability by Salary in 2026
Here is a quick reference showing approximate home prices you can afford at various salary levels, assuming a 20% down payment, 6.5% interest rate, 30-year fixed mortgage, and no existing debts:
| Annual Salary | Monthly Budget (28%) | Max Home Price | Down Payment (20%) | Loan Amount |
|---|---|---|---|---|
| $50,000 | $1,167 | $210,000 | $42,000 | $168,000 |
| $75,000 | $1,750 | $315,000 | $63,000 | $252,000 |
| $100,000 | $2,333 | $420,000 | $84,000 | $336,000 |
| $125,000 | $2,917 | $525,000 | $105,000 | $420,000 |
| $150,000 | $3,500 | $630,000 | $126,000 | $504,000 |
| $200,000 | $4,667 | $840,000 | $168,000 | $672,000 |
These estimates include property taxes (1.1% national average) and homeowner's insurance ($1,500/year). Actual affordability varies by location, credit score, and current interest rates. Use our calculator above for a personalized estimate based on your exact financial situation.
Key Factors That Affect Home Affordability
1. Interest Rates
Interest rates have the single largest impact on your buying power. A 1% increase in rates reduces your purchasing power by approximately 10%. At 5.5%, a $2,000/month budget buys a $352,000 home. At 7.5%, that same budget only affords a $286,000 home — a $66,000 difference.
2. Down Payment Size
A larger down payment directly increases your maximum home price. It also lowers your monthly payment and may eliminate Private Mortgage Insurance (PMI), which costs 0.5-1.5% of the loan amount annually. Putting 10% down instead of 20% on a $350,000 home adds roughly $146-$438/month in PMI.
3. Credit Score
Your credit score determines the interest rate you qualify for. According to FICO, borrowers with scores above 760 receive rates 0.5-1.5% lower than those with scores in the 620-639 range. On a $300,000 mortgage, this difference costs $27,000-$97,000 in additional interest over 30 years.
4. Property Taxes
Property tax rates vary dramatically by state, from 0.31% in Hawaii to 2.23% in New Jersey. On a $400,000 home, that is the difference between $1,240/year and $8,920/year — a $640/month swing that directly affects how much house you can afford.
5. Existing Debt
Every dollar of existing monthly debt reduces how much you can borrow. Paying off a $400/month car payment before applying for a mortgage could increase your purchasing power by $60,000-$70,000.
First-Time Home Buyer Programs in 2026
Several programs help first-time buyers qualify for more home with less money down:
| Program | Min Down Payment | Min Credit Score | Key Benefit |
|---|---|---|---|
| FHA Loan | 3.5% | 580 | Lower credit requirements, higher DTI allowed |
| Conventional 97 | 3% | 620 | PMI cancels at 80% LTV |
| VA Loan | 0% | None (typically 620) | No PMI, no down payment for eligible veterans |
| USDA Loan | 0% | 640 | No down payment in eligible rural areas |
| HomeReady (Fannie Mae) | 3% | 620 | Reduced PMI, allows boarder income |
| Home Possible (Freddie Mac) | 3% | 660 | Reduced PMI, sweat equity for down payment |
Many states and cities also offer down payment assistance (DPA) grants and forgivable loans. Check HUD's local resources page for programs in your area.
Our Calculation Methodology
Our Home Affordability Calculator uses a mortgage qualification model based on the same underwriting guidelines used by Fannie Mae, Freddie Mac, and FHA. Here is exactly how we calculate your results:
- Maximum monthly payment: We apply the 28% front-end DTI ratio to your gross monthly income, then subtract estimated property taxes (1.1% of home value / 12) and insurance ($125/month).
- Debt adjustment: We verify your back-end ratio (36%) by subtracting your monthly debts. If this produces a lower housing budget than the front-end ratio, we use the lower figure.
- Loan amount: Using the available monthly payment, current interest rate, and selected loan term, we reverse-calculate the maximum loan principal using the standard amortization formula.
- Home price: We add your down payment to the maximum loan amount to determine your total purchasing power.
- PMI: If your down payment is less than 20%, we deduct estimated PMI (0.7% of loan annually) from your available monthly budget before calculating the loan amount.
Data sources include the Freddie Mac Primary Mortgage Market Survey for current rates and the Tax Foundation for state property tax data.
Frequently Asked Questions
How much house can I afford on a $100,000 salary?
On a $100,000 annual salary with no existing debts and a 20% down payment, you can typically afford a home in the $380,000-$420,000 range with a 30-year fixed mortgage at current 2026 rates (approximately 6.5%). This assumes property taxes of 1.1% and standard homeowner's insurance. If you have significant debts like car payments or student loans, your maximum will be lower. Use our calculator above for a precise figure based on your specific financial situation.
What is the 28/36 rule for buying a house?
The 28/36 rule states that your monthly housing costs (mortgage, taxes, insurance, PMI, HOA) should not exceed 28% of your gross monthly income, and your total monthly debts (housing costs plus all other debts) should not exceed 36%. For example, if you earn $6,000/month gross, your housing payment should be $1,680 or less, and your total debts should be $2,160 or less. Some loan programs like FHA allow ratios up to 31/43.
How much down payment do I need to buy a house in 2026?
You do not need 20% down to buy a home. Conventional loans require as little as 3% down ($9,000 on a $300,000 home), FHA loans require 3.5%, and VA and USDA loans offer 0% down payment options. However, putting less than 20% down means you will pay Private Mortgage Insurance (PMI), which adds 0.5-1.5% of the loan amount to your annual costs. Many state and local programs offer down payment assistance grants.
Does my credit score affect how much house I can afford?
Yes, significantly. Your credit score determines the interest rate you qualify for, which directly affects your monthly payment and maximum loan amount. A borrower with a 760+ score might get a 6.0% rate, while someone at 620 might pay 7.5%. On a $300,000 loan, that 1.5% difference means an extra $275/month — or about $50,000 less purchasing power. Most conventional loans require a minimum 620 score; FHA loans accept scores as low as 500 with 10% down or 580 with 3.5% down.
Should I max out my home affordability budget?
Financial advisors generally recommend spending less than your maximum approved amount. Just because you qualify for a $450,000 mortgage does not mean you should borrow that much. A conservative approach is to keep your housing costs (including taxes, insurance, and maintenance) at 25% of your take-home pay rather than 28% of gross income. This leaves room for savings, retirement contributions, emergencies, and lifestyle expenses. Being 'house poor' — where most of your income goes to housing — leads to financial stress and limits your ability to build wealth through other investments.
How do property taxes affect home affordability?
Property taxes can significantly reduce how much home you can afford. In a low-tax state like Hawaii (0.31% effective rate), property taxes on a $400,000 home cost about $103/month. In New Jersey (2.23%), the same value home costs $743/month in property taxes — a $640/month difference. That $640 could support an additional $95,000 in mortgage borrowing at current rates. Always research property tax rates in your target area before setting your budget.
