What Is House Affordability?
House affordability is the maximum home price a lender will typically approve you for, based on your income, existing debts, down payment, and the interest rate you qualify for. Rather than asking "what payment can I imagine paying," lenders work backward from strict debt-to-income ratios to cap how much of your gross income can go toward housing and total debt combined.
The two ratios that matter most are the front-end ratio (housing costs alone) and the back-end ratio (housing plus all other debt payments) — commonly capped at 28% and 36% of gross monthly income respectively, though specific loan programs vary.
Max Home Price by Interest Rate
Your budget for principal, interest, and taxes stays the same — only the rate changes, showing how much affordability shifts as rates move.
| Interest Rate | Max Home Price | Monthly P&I |
|---|---|---|
| 5.0% | $563,695 | $2,811 |
| 5.5% | $539,409 | $2,836 |
| 6.0% | $516,735 | $2,858 |
| 6.5% | $495,559 | $2,879 |
| 7.0% | $475,775 | $2,899 |
| 7.5% | $457,285 | $2,918 |
| 8.0% | $439,993 | $2,935 |
How Is Affordability Calculated?
This calculator finds the smaller of two budgets — the front-end limit (income × front-end ratio) and the back-end limit (income × back-end ratio, minus existing debts) — then solves algebraically for the home price whose principal, interest, property tax, insurance, and HOA fit exactly within that monthly budget. Property tax is a percentage of home price, so it's solved for directly rather than estimated separately.
Front-End vs. Back-End Ratios
The front-end ratio looks only at housing costs (principal, interest, taxes, insurance, and HOA) as a share of gross income. The back-end ratio adds in every other recurring debt payment — car loans, student loans, credit card minimums — as a share of the same income. Whichever ratio produces the tighter budget is the one that actually limits how much home you can afford.
Existing Debt Reduces Buying Power Directly
Because the back-end ratio caps total debt as a share of income, every dollar of existing monthly debt payment reduces the housing budget by that same dollar. Paying off a car loan or consolidating credit card debt before applying for a mortgage can meaningfully raise the maximum home price a lender will approve.
Down Payment Affects More Than Just the Loan Size
A larger down payment reduces the loan amount, which lowers the monthly principal and interest payment — freeing up more of your monthly budget for the same total home price, or letting you afford a higher price at the same monthly payment. It also commonly avoids private mortgage insurance once it reaches 20% of the home price, though PMI isn't modeled separately here.
Example — Your Current Inputs
With a $150,000 annual income, $500 in other monthly debts, and a $40,000 down payment, you could afford a home priced around $495,559 — a monthly payment of about $3,500 covering principal, interest, taxes, insurance, and HOA.
Additional Example — A $60,000 Income
A household earning $60,000 a year with $300 in monthly debts and a $20,000 down payment could typically afford a home priced around $220,000-$240,000 at a 6.5% mortgage rate, assuming standard 28%/36% lending ratios — the exact figure depends on local property tax rates and insurance costs.
About These Parameters
- Annual Income & Other Monthly Debts
- Lenders use gross (pre-tax) income, not take-home pay, to compute affordability ratios. Other monthly debts include only the minimum required payments, not the full balances.
- Down Payment & Mortgage Rate
- The down payment directly reduces the loan amount needed, while the mortgage rate determines how much of each monthly payment goes to interest versus principal.
- Property Tax, Insurance & HOA
- These recurring costs are part of most lenders' full housing payment (PITI) even though they don't reduce the loan balance. Property tax rates vary widely by location, so using an accurate local rate matters for a realistic estimate.
- Front-End & Back-End Ratio Limits
- These are the maximum shares of gross income lenders typically allow for housing alone, and for housing plus all other debt combined. Conventional loans commonly use 28% and 36%, though some loan programs allow higher ratios for qualified borrowers.
Frequently Asked Questions
What is the 28/36 rule?
It's a common lending guideline stating housing costs shouldn't exceed 28% of gross monthly income, and total debt payments (including housing) shouldn't exceed 36%. Some loan programs allow higher ratios, especially for borrowers with strong credit or larger down payments.
Does this include closing costs?
No — this calculator estimates ongoing affordability (the monthly payment you can sustain), not one-time closing costs, which typically run 2-5% of the loan amount and are paid separately at closing.
Why is my max home price lower than expected?
Usually because existing monthly debts are eating into your back-end ratio budget, or your local property tax rate is high enough to meaningfully reduce how much loan payment fits inside your overall housing budget.
