What Is a House Affordability Calculator?
A House Affordability Calculator estimates how much home you can afford from your income, monthly debts, down payment, interest rate and loan term. It is useful for first-time buyers setting a budget, and for anyone who wants to check a price range before talking to a lender.
How to Use the House Affordability Calculator
Using the calculator takes about a minute.
- Choose a method: By Debt-to-Income (the calculator works out a safe payment from your income) or By Fixed Budget (you enter the monthly payment you want).
- Enter your annual household income before tax.
- Add your other monthly debt payments, such as car loans, student loans and credit card minimums.
- Enter your down payment.
- Enter the mortgage interest rate.
- Choose the loan term in years.
- Add estimated property tax, home insurance and any HOA fee.
- Pick a debt-to-income setting (conservative 28/36, aggressive 36/43, or your own).
- Click Calculate to see the highest home price that fits, your monthly payment breakdown and an amortization schedule.
House Affordability Formula
Lenders look mainly at your debt-to-income (DTI) ratio. The calculator applies two limits and uses whichever is lower:
- Front-end limit: maximum housing payment = monthly gross income × front-end ratio (for example 28%).
- Back-end limit: maximum housing payment = monthly gross income × back-end ratio (for example 36%) − your other monthly debts.
Property tax, insurance and HOA are taken out of that payment, and the rest is what is left for principal and interest (P&I). The loan that payment supports is:
Loan = P&I × ((1 + r)^n − 1) ÷ (r × (1 + r)^n)
where r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments. Finally:
Affordable home price = Loan + Down payment
Example Calculation
Suppose you earn $90,000 a year, pay $500 a month on other debts, have $40,000 for a down payment, and expect a 6.5%, 30-year fixed mortgage. Using the 28/36 rule:
- Monthly income: $90,000 ÷ 12 = $7,500.
- Front-end limit: 28% × $7,500 = $2,100 a month for housing.
- Back-end limit: 36% × $7,500 − $500 = $2,200, so the front-end limit of $2,100 applies.
- Assume about $400 a month for property tax and insurance. That leaves $1,700 for principal and interest.
- At 6.5% over 30 years, $1,700 a month supports a loan of about $269,000.
- Add the $40,000 down payment: an affordable price of about $309,000.
If you ignored taxes and insurance, the same income would seem to support about $372,000. That gap is why it matters to include every housing cost.
Tips before you shop
- Being approved for a loan is not the same as being comfortable with the payment. Leave room for savings, repairs and other goals.
- Get a local estimate of property tax and insurance; they vary widely by state and county.
- Keep an emergency fund in addition to your down payment and closing costs.
- Lower debts or a larger down payment raise the price you can afford more safely than stretching the loan term.
