How Much House Can You Actually Afford?

Buying a home is exciting—but it’s easy to fall in love with a house that stretches your budget too thin. Lenders use a simple guideline called the 28/36 rule to determine what you can comfortably afford. This calculator applies that rule to your specific numbers, giving you a realistic maximum home price based on your income, debts, and local costs.

What Is the 28/36 Rule?

  • 28% Front-End Ratio: Your total monthly housing payment (principal, interest, taxes, insurance, and PMI if applicable) should not exceed 28% of your gross monthly income.
  • 36% Back-End Ratio: Your total monthly debt payments (housing + car loans + student loans + credit cards) should not exceed 36% of your gross monthly income.

If your numbers fall within these ranges, you’re in a strong position to qualify for a mortgage. If not, the calculator will show you the gap—so you can adjust your expectations, save a larger down payment, or pay down existing debt.

How to Use This Calculator

  • Annual Gross Income: Your total household income before taxes. Include salary, bonuses, and any consistent side income.
  • Monthly Debt Payments: Minimum payments on car loans, student loans, credit cards, and any other recurring debts. Do not include current rent.
  • Down Payment: Cash you plan to put toward the home purchase. A 20% down payment avoids PMI, but many loans allow as little as 3–5% down.
  • Interest Rate: The annual mortgage rate you expect to qualify for. Shop around—rates vary by lender and credit score.
  • Loan Term: 30 years is standard for lower payments; 15 years saves interest but requires higher monthly payments.
  • Property Tax & Insurance: Enter your local estimates. A common rule of thumb is 1–2% of home value for annual property tax, and $800–$1,500 for insurance.
  • Lawyer / Closing Fees: Typically 1–3% of the home price. These are paid at closing and reduce the cash available for your down payment.
  • Other Fees: Inspections, moving costs, or any other upfront expenses you expect to pay.

📌 Pro Tip: The calculator includes PMI (Private Mortgage Insurance) if your down payment is less than 20% of the home price. PMI typically costs 0.5%–1% of the loan amount annually and is added to your monthly payment.

What If the Number Is Lower Than You Expected?

Don’t be discouraged. This is a conservative, lender-friendly estimate. Here are a few levers you can pull to increase your buying power:

  • Pay down high-interest debt to lower your back-end DTI ratio.
  • Increase your down payment to reduce the loan amount and potentially eliminate PMI.
  • Improve your credit score to qualify for a lower interest rate.
  • Consider a less expensive area or a smaller home to start building equity.

Frequently Asked Questions

Does this calculator include HOA fees?

No. If you’re buying a condo or home in a planned community, HOA dues will increase your monthly housing cost. Add your estimated HOA fee to the monthly debt input for a more accurate picture.

What if I have a co-borrower?

Combine both incomes and both monthly debt payments, then enter the totals. Lenders consider the full household financial picture.

Is the 28/36 rule strict?

It’s a guideline, not a law. Some lenders allow higher DTIs (up to 43% or even 50% for well-qualified buyers). But staying within 28/36 keeps your payment comfortable and leaves room for life’s surprises.

Find Out How Much Home You Can Comfortably Afford

Buying a home is one of the biggest financial decisions you’ll ever make — and guessing your budget can lead to stress, overpayment, or long‑term financial strain. This calculator uses the widely accepted 28/36 rule to help you understand a realistic home price based on your income, debts, and down payment.

What the 28/36 Rule Means

  • 28% Rule: Your monthly housing costs (mortgage, taxes, insurance) should not exceed 28% of your gross income.
  • 36% Rule: Your total monthly debt payments (housing + loans + credit cards) should not exceed 36% of your gross income.

This calculator applies both rules to determine the maximum home price that fits your financial comfort zone — not just what a lender might approve.

What This Calculator Shows

  • Affordable Home Price: Based on income, debts, and down payment.
  • Estimated Monthly Payment: Including principal, interest, taxes, and insurance.
  • Debt‑to‑Income Impact: How your existing debts affect your buying power.

Why This Matters

Many buyers focus only on the mortgage payment, but long‑term affordability depends on the full picture — taxes, insurance, HOA fees, and your other monthly obligations. This tool helps you avoid becoming “house poor” by showing a realistic, sustainable budget.

Tips for Improving Affordability

  • Increase your down payment to reduce your loan amount.
  • Pay down high‑interest debt to improve your DTI ratio.
  • Compare mortgage rates from multiple lenders.
  • Consider a slightly smaller home to reduce long‑term costs.
