The question "how much house can I afford?" has two very different answers: what a lender will approve you for, and what you can comfortably afford without stretching your finances. These numbers are often not the same — and confusing them is one of the most common financial mistakes first-time homebuyers make.
This guide walks through how to translate your salary into a realistic home price estimate, what factors push that number up or down, and how to use the How Much House Can I Afford Calculator to test different scenarios before you start house hunting.
Quick Answer: How much house can you afford on your salary? A commonly used starting guideline is that your total monthly housing costs — principal, interest, taxes, insurance, and HOA — should not exceed 28% of your gross monthly income. On a $110,000 household income, that's approximately $2,567/month for all housing costs. With a 6.75% mortgage rate, 30-year term, $40,000 down payment, and typical tax and insurance estimates, that income level may support a home price around $300,000–$350,000 depending on location and debt load. Use the calculator for a specific estimate based on your actual numbers.
Why "What You Can Borrow" and "What You Can Afford" Are Different
Lenders approve loans based on whether you can make the payments — not whether those payments leave you room for savings, emergencies, car repairs, or lifestyle. A lender approving you for a $450,000 mortgage doesn't mean a $450,000 home is financially smart for your situation.
The difference matters because:
- Lender approval is based on income and existing debt ratios, with little visibility into your full financial picture
- True affordability includes your complete budget — retirement contributions, savings goals, childcare, healthcare, and the ongoing costs of owning the specific home
- What you qualify for can change with rate environment, loan program, and underwriting standards
- What's comfortable depends on your values, risk tolerance, and what you want to be able to do financially beyond housing
The How Much House Can I Afford Calculator uses common income and debt ratio guidelines to give you a planning estimate — not a lender approval. It's a starting point for understanding your range, not a final answer.
The Salary-to-Home-Price Framework
The 28% Front-End Ratio
A commonly referenced affordability guideline — used by many lenders as a front-end ratio — is that total monthly housing costs should not exceed 28% of gross monthly income. Actual lender standards vary by loan program, credit profile, and underwriting criteria, so treat this as a planning benchmark rather than a fixed rule.
Maximum housing budget = Gross monthly income × 28%
Examples by income level:
| Annual Salary | Gross Monthly | 28% Housing Budget |
|---|---|---|
| $60,000 | $5,000 | $1,400/month |
| $80,000 | $6,667 | $1,867/month |
| $100,000 | $8,333 | $2,333/month |
| $110,000 | $9,167 | $2,567/month |
| $130,000 | $10,833 | $3,033/month |
| $150,000 | $12,500 | $3,500/month |
The monthly housing budget includes more than the mortgage payment. Property taxes, insurance, and HOA fees all count — and they can easily add $400–$800/month on top of the principal and interest payment.
From Monthly Budget to Home Price
To estimate the home price that fits a given monthly housing budget, the calculator works backwards from the budget to the maximum mortgage, then adds the down payment.
Example: $110,000 income, $650/month existing debt, $40,000 down, 6.75% rate, 30-year term, 1.2% property tax, $150/month insurance, $75/month HOA:
- Gross monthly income: $9,167
- 28% housing budget: $2,567
- 36% total debt budget: $3,300 (minus $650 existing debt = $2,650 available for housing)
- Binding constraint: $2,567 (lower of the two)
- Less taxes ($347), insurance ($150), HOA ($75): leaves ~$1,995 for principal and interest
- At 6.75% for 30 years, $1,995/month supports a loan of approximately $307,000
- Add $40,000 down payment: home price estimate ≈ $347,000

What Actually Moves Your Affordable Home Price
Existing Debt Payments
This is the factor most first-time buyers underestimate. Existing debt — car loans, student loans, credit card minimums — directly reduces how much of your income can go toward housing.
Impact on a $110,000 income at 6.75%, 30 years, $40,000 down:
| Monthly Debt Payments | Estimated Affordable Home Price |
|---|---|
| $0 | ~$445,000 |
| $300 | ~$415,000 |
| $650 | ~$347,000 |
| $1,000 | ~$280,000 |
| $1,500 | ~$180,000 |
Going from $0 to $1,000 in monthly debt payments reduces the affordable home price by approximately $165,000 on the same income. Paying off debt before buying a home is one of the most impactful things you can do to increase your price range.
Interest Rate
Mortgage rate changes have a significant effect on how much home a given monthly budget can support.
$110,000 income, $650/month debt, $40,000 down — home price estimate by rate:
| Mortgage Rate | Estimated Affordable Home Price |
|---|---|
| 5.0% | ~$410,000 |
| 5.75% | ~$385,000 |
| 6.75% | ~$347,000 |
| 7.5% | ~$318,000 |
| 8.0% | ~$302,000 |
A 2% rate increase reduces the estimated affordable home price by roughly $100,000 on this income level. This is why buyers who purchased homes when rates were low can afford significantly more house than buyers with the same income today.
Down Payment
A larger down payment reduces the loan amount needed and can meaningfully increase the home price you can afford within the same monthly budget.
$110,000 income, $650/month debt, 6.75% rate, 30 years:
| Down Payment | Estimated Affordable Home Price |
|---|---|
| $10,000 | ~$320,000 |
| $20,000 | ~$330,000 |
| $40,000 | ~$347,000 |
| $60,000 | ~$365,000 |
| $80,000 | ~$383,000 |
Each additional $20,000 in down payment adds approximately $17,000–$20,000 to the affordable home price estimate.
Property Taxes and Insurance
These are location-specific costs that vary significantly — and they're often underestimated by first-time buyers.
Effect on the same monthly budget at different tax rates ($110,000 income, standard assumptions):
| Property Tax Rate | Monthly Tax on $347K Home | Remaining for P&I | Home Price Impact |
|---|---|---|---|
| 0.5% | ~$145 | Higher | Higher price |
| 1.0% | ~$290 | Moderate | Moderate price |
| 1.2% | ~$347 | Less | Base estimate |
| 2.0% | ~$578 | Less | ~$50K lower |
| 2.5% | ~$723 | Much less | ~$80K lower |
In high property tax states, the same income and mortgage rate can support a significantly lower home price because so much of the housing budget is absorbed by taxes.
The Gap Between Lender Approval and Comfortable Affordability
Many conventional lenders use a total debt-to-income limit in the range of 43–45%, though the exact threshold varies by loan program, lender, and borrower profile — and some programs allow higher ratios in certain cases. What does that mean in practice?
At 43% DTI on a $110,000 income:
- Total monthly debt budget: $3,938
- Minus $650 existing debt: $3,288 available for housing
- After taxes and insurance: approximately $2,766 for principal and interest
- Estimated maximum loan: ~$424,000
- Add $40,000 down: ~$464,000 potential approval
The calculator's estimate using standard guidelines: ~$347,000
The gap — $117,000 — represents the difference between maximum lender approval and a housing cost that leaves meaningful room for savings, retirement, and unexpected expenses.
Neither number is wrong. The lender approval tells you the ceiling. The affordability estimate tells you what's financially comfortable. Buying closer to the ceiling means less flexibility elsewhere in your budget.

What the Calculator Doesn't Include — But You Should Think About
The How Much House Can I Afford Calculator is a planning estimate, not a lender pre-approval. It applies common affordability ratio guidelines to your inputs — it does not model your credit profile, loan program eligibility, or the full set of costs involved in buying and owning a home. Several real costs aren't in the model:
PMI (Private Mortgage Insurance) If your down payment is less than 20%, most lenders require PMI — typically 0.5–1.5% of the loan amount annually. On a $300,000 loan, that's $125–$375/month added to your housing cost. The calculator doesn't include PMI, which means its estimate may be slightly optimistic if you're putting less than 20% down.
Cash reserves at closing Many lenders require cash reserves — often several months of mortgage payments — to remain after the down payment and closing costs. Reserve requirements vary by loan program and lender. These funds need to exist before closing, which means your total cash need is higher than the down payment alone.
Ongoing maintenance costs Homeownership comes with ongoing maintenance and repair costs that vary significantly by property age, condition, and location. Whatever your estimate, this is a real cost that needs to fit in your budget alongside the mortgage payment — and it's not reflected in the calculator result.
Changes after purchase Life changes — job changes, family additions, income shifts — happen. A mortgage payment that's comfortable at 28% of income today becomes a different story if income drops or major new expenses arrive.
A Practical Approach to Setting Your Budget
Rather than working backward from the maximum you can afford, consider working forward from what you want your full financial picture to look like:
Step 1: Decide your savings rate How much do you want to contribute to retirement, emergency savings, and other goals each month? Subtract this from take-home pay first.
Step 2: Estimate all homeownership costs Monthly payment, taxes, insurance, HOA, maintenance reserve, and utilities. This is your full housing cost — not just the mortgage.
Step 3: Check what's left After housing and savings, do you have enough for everything else — food, transportation, healthcare, childcare, entertainment? If not, the home price needs to come down.
Step 4: Run the numbers Use the How Much House Can I Afford Calculator to find the home price that produces the monthly payment you identified in steps 1–3. This gives you a target price based on your actual financial priorities, not just the maximum ratio allows.
How to Use the Calculator Responsibly
The calculator is most useful when you run at least two scenarios — not just the maximum.
Run a comfortable scenario first. Enter your income, debts, and a down payment that leaves a meaningful cash buffer after closing. Use a conservative rate assumption. Review the resulting home price and monthly payment — this is your financially comfortable range.
Then run a stretch scenario. Use a higher down payment or lower rate to see what maximum the ratios allow. Compare the monthly payment to your actual take-home budget — not just to the 28% gross income guideline.
Check both against your full monthly budget. Use the Budget Calculator to see how the mortgage payment fits alongside all your other expenses, savings, and debt payments. If the stretch scenario leaves no room for savings or leaves you dependent on everything going right, the comfortable scenario is the more sustainable choice.
Leave room for what comes after closing. Maintenance costs, moving expenses, furnishings, and the unexpected don't show up in the calculator. Build in a buffer before committing to any price.

Frequently Asked Questions
How much house can I afford on a $75,000 salary?
On a $75,000 gross income, the 28% guideline gives a housing budget of approximately $1,750/month. Depending on your down payment, existing debt, local property taxes, and mortgage rate, this may support a home price roughly in the range of $200,000–$280,000. Run your specific numbers through the How Much House Can I Afford Calculator for a more accurate estimate.
Should I use gross income or take-home pay for the 28% rule?
The 28% guideline — and the affordability calculator — uses gross income (before taxes). This is the standard for lender qualification calculations. When evaluating how a mortgage fits your actual budget, also check the payment against your take-home pay to make sure it's genuinely comfortable after taxes.
What if I can only put 5–10% down?
A smaller down payment means a larger loan for the same home price — which reduces the price you can afford within the same monthly budget. It also typically means PMI applies until you reach 20% equity, which adds to monthly costs. Run both a 5% and 20% down scenario in the calculator to see the difference.
How do I account for a partner's income?
Enter the combined household gross income. If both partners' incomes are relatively stable, combining them is appropriate. If one income is variable or at risk, consider whether the mortgage would remain manageable on one income alone — a useful stress test for long-term financial resilience.
Does the calculator tell me what a lender will approve?
No — this is a planning estimate, not a lender pre-approval. Actual lender approvals depend on your credit score, credit history, employment history, loan program, cash reserves, and specific underwriting criteria. The calculator gives you a reasonable planning range based on common affordability ratios.
Key Takeaways
- The 28% guideline — housing costs at or below 28% of gross monthly income — is a common starting point, not a guarantee of comfort
- Existing debt reduces your home-buying power significantly — $1,000/month in existing payments can lower your affordable price by $150,000+
- Lender approval is a ceiling, not a recommendation — buying at maximum qualification leaves little financial flexibility
- Interest rate has a major impact — a 2% rate difference can shift the affordable home price by $80,000–$100,000 on a typical income
- Property taxes, insurance, and HOA are real costs that consume a meaningful share of the housing budget — especially in high-tax areas
- The calculator does not include PMI, maintenance costs, or cash reserve requirements — factor these in separately
- Use the How Much House Can I Afford Calculator to get a planning estimate based on your actual income, debt, and down payment
