What is Home Buying Power?
Home buying power refers to the maximum home price you can afford based on your current financial situation. It takes into account:
- Income – Total monthly or annual earnings
- Debts – Monthly obligations such as loans, credit cards, and mortgages
- Down Payment – Initial amount you can put toward the home
- Interest Rates – Mortgage interest rates affect monthly payments
- Loan Term – Duration of the mortgage (e.g., 15 or 30 years)
By combining these factors, the calculator provides a realistic estimate of what you can comfortably spend on a home.
Home Buying Power Formula
The general formula for calculating home affordability is:
Monthly Mortgage Payment = (Home Price − Down Payment) × Monthly Interest Rate / (1 − (1 + Monthly Interest Rate)^−Number of Payments)
Where:
- Home Price = The estimated purchase price
- Down Payment = Your upfront payment
- Monthly Interest Rate = Annual rate ÷ 12
- Number of Payments = Loan term × 12 months
To determine maximum home price, the calculator rearranges this formula using your monthly budget for mortgage payments.
