Buying a home is a major financial decision, and knowing how much house you can afford is a critical first step. Our home affordability calculator gives you a clear, personalized estimate based on your income, expenses, and preferences.

What Does the Calculator Do?

This tool helps you estimate the maximum home price you can comfortably afford. It factors in your:

  • Annual income

  • Monthly debt payments

  • Down payment amount

  • Loan term and interest rate

  • Property tax rate

  • Home insurance and HOA fees

  • Preferred debt-to-income (DTI) ratio

By combining all of these inputs, the calculator determines your estimated monthly housing budget and translates that into a maximum home price range.

Why It Matters

Lenders typically use a debt-to-income ratio to decide how much they’re willing to loan. Staying within a reasonable DTI ratio ensures you won’t be overextending yourself financially. This calculator helps you stay within your limits while also giving you a sense of your options—whether you want to take a conservative, standard, or more aggressive approach.

How to Use It

  1. Enter your income and debts – Start with your gross annual income and your current monthly debt obligations.

  2. Add in your down payment – The more you can put down upfront, the more you can afford overall.

  3. Select your loan terms – Choose your preferred loan duration and interest rate.

  4. Include property taxes and insurance – These can vary by location, but they significantly affect your monthly payment.

  5. Adjust your DTI preference – Go conservative if you want to play it safe, or increase it if you’re comfortable taking on more financial risk.

After you hit “Calculate,” you’ll see your estimated home price limit, a range of budget scenarios (conservative to aggressive), and a full breakdown of estimated monthly costs—including principal, interest, taxes, insurance, and HOA fees if applicable.

Tips to Improve Your Affordability

  • Increase your down payment to reduce how much you need to borrow.

  • Pay down existing debts to improve your DTI ratio.

  • Shop for better interest rates to lower your monthly payment.

  • Increase your income through raises, side work, or career moves.

Bottom Line

Knowing your price range before house hunting helps you stay focused, realistic, and financially prepared. Use this calculator anytime your financial picture changes or you want to test different scenarios.

Our Testing Process

We tested this calculator with real-world examples using the 28/36 rule. For an $80,000 annual income ($6,667/month), the 28% front-end ratio allows $1,867/month for housing (PITI), and the 36% back-end ratio allows $2,400/month for total debt. Our team verifies the debt-to-income calculations against CFPB guidelines and tests the tool with various income, debt, and down payment combinations to confirm it produces correct results.

The 28/36 Rule Explained

28% Front-End Ratio: Your monthly housing expenses (principal, interest, property taxes, homeowner’s insurance, and HOA fees) should not exceed 28% of your gross monthly income.

36% Back-End Ratio: Your total monthly debt payments (housing expenses plus car loans, credit cards, student loans, etc.) should not exceed 36% of your gross monthly income.

Example: With $6,667/month gross income, max housing = $1,867/month (28%), max total debt = $2,400/month (36%).

Frequently Asked Questions

What is the 28/36 rule?
The 28/36 rule is a guideline used by lenders: housing expenses should not exceed 28% of gross monthly income (front-end ratio), and total debt payments should not exceed 36% (back-end ratio).

What counts as housing expenses?
PITI: Principal, Interest, property Taxes, and homeowner’s Insurance, plus HOA fees if applicable.

Can I afford a house with a higher DTI?
Some loan programs allow higher DTIs (up to 43-50% for qualified mortgages). However, a lower DTI gives you more financial flexibility.

How does credit score affect affordability?
A higher credit score typically qualifies you for lower interest rates, which reduces your monthly payment and increases how much house you can afford.
