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 $650/month in existing debt, a 6.75% mortgage rate, 30-year term, $40,000 down payment, 1.2% property tax, $150/month homeowners insurance, $75/month HOA, and PMI excluded, the calculator estimates an affordable home price of approximately $347,464. 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 (about $347), insurance ($150), HOA ($75), and $0 PMI: leaves about $1,994 for principal and interest
- At 6.75% for 30 years, that payment supports a loan of approximately $307,464
- Add $40,000 down payment: home price estimate ≈ $347,464
Use the How Much House Can I Afford Calculator to run this calculation for your specific income, debts, and down payment.
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 with $110,000 income, Standard 28/36, 6.75%, 30 years, $40,000 down, 1.2% property tax, $150/month homeowners insurance, $75/month HOA, and PMI excluded:
| Monthly Debt Payments | Estimated Affordable Home Price |
|---|---|
| $0 | $347,464 |
| $300 | $347,464 |
| $650 | $347,464 |
| $1,000 | $311,841 |
| $1,500 | $245,050 |
Debt does not reduce the estimate until the back-end DTI constraint falls below the 28% housing-ratio cap. In this scenario, $0, $300, and $650 of monthly debt all leave the housing ratio as the binding constraint, so each produces the same $347,464 estimate. Above about $733/month, DTI becomes limiting: at $1,000 of debt the estimate is $311,841, about $35,623 below the housing-ratio-limited result, and at $1,500 it falls to $245,050.
Interest Rate
Mortgage rate changes have a significant effect on how much home a given monthly budget can support.
The same scenario with $650/month debt — home price estimate by rate:
| Mortgage Rate | Estimated Affordable Home Price |
|---|---|
| 5.0% | $401,430 |
| 5.75% | $376,711 |
| 6.75% | $347,464 |
| 7.5% | $327,991 |
| 8.0% | $316,057 |
Moving from a 5% rate to an 8% rate reduces the estimated affordable home price by about $85,373 in this scenario. The housing budget is unchanged, but the higher rate means the same principal-and-interest payment supports a smaller loan.
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 | $321,471 |
| $20,000 | $330,135 |
| $40,000 | $347,464 |
| $60,000 | $364,792 |
| $80,000 | $382,120 |
From a $20,000 down payment onward in this scenario, each additional $20,000 raises the estimated affordable home price by about $17,329. The increase is less than dollar-for-dollar because property tax rises with the home price while the monthly housing budget stays fixed.
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, $650/month debt, $40,000 down, 6.75%, 30 years, $150/month insurance, $75/month HOA, and PMI excluded):
| Property Tax Rate | Estimated Affordable Home Price | Monthly Property Tax | Monthly P&I | Impact vs. 1.2% Base |
|---|---|---|---|---|
| 0.5% | $376,827 | $157 | $2,185 | +$29,363 |
| 1.0% | $355,376 | $296 | $2,046 | +$7,912 |
| 1.2% | $347,464 | $347 | $1,994 | Base |
| 2.0% | $319,050 | $532 | $1,810 | −$28,414 |
| 2.5% | $303,537 | $632 | $1,709 | −$43,927 |
In this scenario, raising the property tax assumption from 1.2% to 2.0% lowers the estimated affordable home price by $28,414; at 2.5%, the estimate is $43,927 below the base. The monthly budget is unchanged, but more of it is absorbed by property tax.
A Ratio-Based Ceiling vs. Comfortable Affordability
Mortgage DTI treatment depends on the loan program, transaction, underwriting path, borrower profile, and any lender overlays. The 43% back-end ratio below is only an illustrative planning comparison; it is not a universal conventional-loan limit or a prediction of what a lender will approve.
At an illustrative 43% total DTI on a $110,000 income, using the same 6.75% rate, 30-year term, 1.2% property tax, $150/month insurance, $75/month HOA, $40,000 down payment, and excluded PMI:
- Total monthly debt budget: approximately $3,942
- Minus $650 existing debt: approximately $3,292 available for housing
- At a $444,311 home price, property tax is about $444/month, leaving about $2,622 for principal and interest after insurance and HOA
- That principal-and-interest payment supports a loan of approximately $404,311
- Add $40,000 down: approximately $444,311 as an illustrative ratio-based ceiling
The calculator's estimate using its standard 28/36 guidelines and the same cost assumptions: $347,464
The gap — approximately $96,848 — illustrates the difference between a higher ratio-based ceiling and a housing cost that leaves more room for savings, retirement, and unexpected expenses. It is not a lender pre-approval; actual qualification depends on the loan program, underwriting method, credit profile, reserves, and lender rules.
The two figures serve different planning purposes. The 43% illustration shows what the same assumptions produce at a higher back-end ratio; it does not predict an approval. The standard affordability estimate shows a more conservative planning range. A higher housing payment leaves 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) The worked and sensitivity examples above use the calculator's Exclude PMI option. If the estimated down payment is below 20%, the calculator can instead include its simple planning estimate of 0.5% of the loan amount per year. Actual PMI pricing and requirements depend on the lender, loan program, and borrower profile, so verify them before relying on the result.
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 once DTI is binding — in the worked scenario, $0 and $650/month both produce $347,464 because the 28% housing ratio still limits the result, while $1,000/month lowers it to $311,841
- Maximum qualification and comfortable affordability are different — a higher payment can leave less financial flexibility, and any actual approval depends on the applicable underwriting path
- Interest rate has a major impact — in the worked scenario, moving from 5% to 8% lowers the estimate from $401,430 to $316,057
- Property taxes, insurance, and HOA consume part of the housing budget — in the worked scenario, raising the property tax assumption from 1.2% to 2.5% lowers the estimate from $347,464 to $303,537
- The examples exclude PMI; the calculator can add a simple PMI planning estimate, but it does not model lender-specific pricing, maintenance costs, or cash reserve requirements
- Use the How Much House Can I Afford Calculator to get a planning estimate based on your actual income, debt, and down payment
