The Zillow Affordability Calculator helps determine how much house you can afford based on your income, debts, and a standard multiplier. It provides a quick estimate of your home buying budget.
The calculator uses the Zillow affordability formula:
Where:
Explanation: The formula calculates your annual income multiplied by a standard affordability ratio, then subtracts your existing debts to determine your maximum home price.
Details: Calculating an affordable home price helps prevent overextending your finances and ensures you can comfortably make mortgage payments while covering other living expenses.
Tips: Enter your gross monthly income, select a multiplier (typically 3), and include all outstanding debts. The calculator will estimate your maximum affordable home price.
Q1: What multiplier should I use?
A: Most lenders recommend 3-4 times your annual income. Conservative buyers may use 2-3, while those with stable incomes might use 4.
Q2: What debts should I include?
A: Include all outstanding loans (car, student, personal) and credit card balances. Don't include regular living expenses.
Q3: Does this include down payment?
A: No, this calculates total home price. You'll need additional funds for down payment (typically 5-20%).
Q4: What about property taxes and insurance?
A: These are not included in this basic calculation. For a more accurate estimate, use a mortgage calculator that includes these factors.
Q5: How does interest rate affect affordability?
A: Higher rates decrease affordability. This calculator assumes current average rates. For precise estimates, consult a mortgage lender.
