At a Glance
Home Affordability Calculator estimates the highest home price you could afford from your income, debts, down payment and mortgage rate. It applies the 28/36 rule and gives a monthly payment breakdown.
| Feature | What you get | Good for |
|---|---|---|
| 28/36 rule | Housing costs are capped at 28% of gross monthly income and total debts at 36%. The more conservative limit sets the maximum price. | Budgeting a price range before talking to lenders |
| Inputs | Income, existing debts, down payment and mortgage rate feed the estimate. | Buyers comparing different down payments or rates |
| Payment breakdown | Monthly principal and interest, property taxes (1.1% default), homeowners insurance (0.35% default), PMI and HOA fees. | Seeing the full monthly cost, not just the loan payment |
| PMI | PMI is included when the down payment is under 20%, typically 0.3% to 1.5% of the loan amount per year. | Buyers putting down less than 20% |
| DTI gauge | A debt-to-income gauge rates the back-end ratio from Excellent (28% or less) to High Risk (43-50%). | Judging how stretched a budget would be |
| Charts | An amortization chart shows the loan balance over time, and a pie chart shows what makes up the payment. | Understanding where each monthly dollar goes |
How the Calculator Works
This calculator uses the industry-standard 28/36 rule to determine your maximum affordable home price:
- Front-end ratio (28%): Your total housing costs (mortgage payment, property taxes, insurance, HOA, PMI) should not exceed 28% of your gross monthly income.
- Back-end ratio (36%): Your total monthly debts (housing costs plus car payments, student loans, credit cards, etc.) should not exceed 36% of your gross monthly income.
The calculator uses the more conservative of these two limits to ensure you get a realistic, sustainable home price estimate.
Understanding Your Results
Maximum Home Price
This is the highest home price you can comfortably afford while staying within recommended debt-to-income guidelines. It combines your maximum loan amount plus your down payment.
Monthly Payment Breakdown
Your monthly housing payment (often called PITI or PITIA) includes:
- Principal & Interest (P&I): The actual mortgage payment that goes toward paying off your loan and interest charges.
- Property Taxes: Annual property taxes divided by 12. The default rate is 1.1%, but varies significantly by location.
- Homeowners Insurance: Required coverage protecting your home. Default estimate is 0.35% of home value annually.
- PMI (Private Mortgage Insurance): Required if your down payment is less than 20%. Typically 0.3% to 1.5% of loan amount annually.
- HOA Fees: Monthly fees if your property is in a homeowners association.
Debt-to-Income (DTI) Ratios
The DTI gauge shows where your ratios fall compared to lending guidelines:
| Rating | Back-end DTI | Interpretation |
|---|---|---|
| Excellent | ≤ 28% | Very comfortable; plenty of budget cushion |
| Good | 28-33% | Solid affordability within standard guidelines |
| Acceptable | 33-36% | Within typical limits; most lenders will approve |
| Stretched | 36-43% | Near upper limit; less room for unexpected costs |
| High Risk | 43-50% | Above standard limits; may need excellent credit |
Tips for Home Buyers
💡 Ways to Increase Your Home Buying Power
- Increase your down payment: A larger down payment means a smaller loan, lower monthly payments, and possibly avoiding PMI.
- Pay down existing debts: Reducing your monthly debt payments improves your back-end DTI ratio.
- Improve your credit score: A higher score can qualify you for better interest rates.
- Consider a longer loan term: A 30-year mortgage has lower monthly payments than a 15-year (but more total interest).
- Shop for better rates: Even a 0.25% rate difference significantly impacts affordability.
The 20% Down Payment Myth
While 20% down is ideal to avoid PMI, it is not required. Many buyers successfully purchase homes with 3-10% down. Consider:
- FHA loans: As low as 3.5% down with credit score of 580+
- Conventional loans: Some allow 3-5% down for first-time buyers
- VA loans: 0% down for eligible veterans
- USDA loans: 0% down in eligible rural areas
📊 How Interest Rates Affect Affordability
Interest rates have a significant impact on your buying power. Here is how a rate change affects a 30-year mortgage:
- At 6.0%: A $300,000 loan costs $1,799/month (P&I)
- At 6.5%: Same loan costs $1,896/month (+$97)
- At 7.0%: Same loan costs $1,996/month (+$197)
A 1% rate increase typically reduces your buying power by about 10%.
What This Calculator Does Not Include
This is an estimate based on general guidelines. It does not account for:
- Your credit score (which affects your actual rate and approval)
- Local housing market conditions
- Other assets or savings you may have
- Future income changes
- Closing costs (typically 2-5% of home price)
- Moving and furnishing costs
- Home maintenance reserve (budget 1-2% of home value annually)
Frequently Asked Questions
How much house can I afford on my salary?
A common guideline is that you can afford a home priced at 2.5 to 3 times your annual gross income. However, lenders use debt-to-income (DTI) ratios: the 28/36 rule suggests your housing costs should not exceed 28% of gross monthly income, and total debts should not exceed 36%. Use our calculator to get a personalized estimate based on your specific financial situation.
What is the 28/36 rule for mortgages?
The 28/36 rule is a lending guideline where: (1) Your front-end ratio (housing costs including mortgage, taxes, insurance) should not exceed 28% of your gross monthly income, and (2) Your back-end ratio (total monthly debts including housing) should not exceed 36% of your gross monthly income. Some lenders allow higher ratios for borrowers with excellent credit.
How much down payment do I need for a house?
Traditional mortgages often require 20% down to avoid Private Mortgage Insurance (PMI). However, many loan programs accept less: FHA loans require as little as 3.5% down, and some conventional loans accept 3-5% down. A larger down payment reduces your loan amount, monthly payments, and may get you a better interest rate.
What is PMI and when is it required?
Private Mortgage Insurance (PMI) is required when your down payment is less than 20% of the home price (loan-to-value ratio above 80%). PMI typically costs 0.3% to 1.5% of the original loan amount per year. Once you reach 20% equity, you can request PMI removal; it automatically cancels at 22% equity.
Should I get a 15-year or 30-year mortgage?
A 30-year mortgage has lower monthly payments, providing more budget flexibility. A 15-year mortgage has higher payments but significantly less total interest (often 50%+ savings). Choose 15 years if you can comfortably afford the higher payment; choose 30 years for lower payments with the option to pay extra when possible.
How do interest rates affect home affordability?
Interest rates significantly impact affordability. A 1% increase in rate can reduce your buying power by about 10%. Lower rates mean you can afford a higher-priced home with the same monthly payment.
