About How much house can I afford?
How much house can I afford? Lenders usually answer with the 28/36 rule: your total housing payment should be no more than 28% of your gross monthly income, and all your debts together no more than 36%. This house affordability calculator applies that rule to your numbers to find a realistic price range.
The calculator works backwards from the payment you can afford, including property tax, homeowner’s insurance and HOA fees, to the home price that payment supports. A larger down payment or a lower interest rate raises your price range; existing debts such as car loans and student loans lower it.

Frequently asked questions
What is the 28/36 rule?
Spend no more than 28% of gross monthly income on housing (mortgage, tax, insurance, HOA) and no more than 36% on all debts combined, including housing.
How much house can I afford on a $100,000 salary?
With modest debts, a 20% down payment and rates around 6–7%, often roughly $350,000–$450,000. Enter your own numbers above for a personal estimate.
Does my credit score matter?
Yes. A higher score usually gets a lower mortgage rate, which increases how much house you can afford.
Should I buy at the top of my range?
Not necessarily. Leave room for maintenance, savings and emergencies. The conservative setting gives a more comfortable budget.
Is this financial advice?
No. Lenders consider many other factors. Get pre-approved to know your exact budget.
