Determining how much house you can afford is an essential step in the home-buying process. This calculator helps you estimate the maximum home price you can afford based on your financial situation.
House Affordability Calculation Formula
The following formula is used to determine the maximum house price you can afford based on your income, debt, down payment, interest rate, and loan term.
Max House Price = Down Payment + (Max Monthly Payment / Interest Rate) * (1 - (1 + Interest Rate)^(-Loan Term))
Variables:
- Max House Price is the estimated maximum amount you can spend on a house ($)
- Down Payment is the initial amount of money paid upfront ($)
- Max Monthly Payment is the maximum amount you can afford to pay each month for the mortgage ($)
- Interest Rate is the annual interest rate on the mortgage divided by 12 and converted to a decimal
- Loan Term is the duration of the loan in months
To calculate the maximum house price, first determine your maximum monthly payment based on your income and existing debt. Then use the formula to find out how much you can afford based on the loan’s interest rate and term.
