Understanding House Affordability
House affordability is calculated using standard lending guidelines known as the 28/36 rule:
The 28/36 Rule
36% Rule: Total debt ≤ 36% of gross monthly income
Housing Costs: Mortgage + Property Tax + Insurance + HOA Fees
Lenders use these rules to determine if you can afford a mortgage. The calculator uses the more restrictive limit to ensure you stay within both guidelines.
What is Included in Monthly Payment?
- Principal & Interest: Monthly mortgage payment based on loan amount, interest rate, and term
- Property Tax: Annual property tax divided by 12 months
- Home Insurance: Annual home insurance divided by 12 months
- HOA Fees: Monthly homeowners association fees (if applicable)

Debt-to-Income Ratio Guidelines

Frequently Asked Questions
Most lenders prefer a debt-to-income ratio below 43%. The lower your DTI, the better your chances of loan approval and favorable terms. A DTI below 36% is considered excellent and qualifies for the best rates. A DTI of 43% is generally the maximum for qualified mortgages, while higher DTIs may require special loan programs or excellent credit scores.
The general rule is that your housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income, and your total debt (housing + other debts) should not exceed 36% of your gross monthly income. Enter your income and expenses in our calculator to get an accurate estimate of how much house you can afford.
Yes, if you will both be on the mortgage application and both incomes are stable, you can include both incomes in the annual income field. Add your combined annual gross incomes together. Also include both spouses’ monthly debts in the monthly debts field for accurate calculations.
Conventional loans typically require 20% down payment to avoid private mortgage insurance (PMI), but some programs accept as little as 3-5%. FHA loans require 3.5% down with good credit. VA loans (for veterans) may require no down payment. Larger down payments reduce loan amount and monthly payments, increasing affordability. Use the calculator to see how different down payment amounts affect your monthly payment.
Include all monthly debt obligations: credit card minimum payments, car loans, student loans, personal loans, and any other recurring monthly debts. Do not include current rent or utilities, as these will be replaced by housing costs. Lenders look at your total monthly obligations when determining affordability.
No, this calculator does not include credit score, which affects the interest rate you qualify for. If you have excellent credit (740+), you may qualify for lower interest rates than the default, which would increase affordability. If you have lower credit scores, you may receive higher interest rates, reducing affordability. Use current market rates as a baseline and adjust based on your credit profile.
