Formula:
This calculator estimates your maximum potential loan amount and affordable home price by considering your income, existing debts, down payment, desired loan term, and an estimated interest rate. It uses standard debt-to-income ratios (front-end & back-end) often employed by lenders to determine your monthly principal & interest (P&I) capacity.
Key variables include:
- Annual Gross Income (I): Your total earnings before deductions.
- Total Monthly Debts (D): Recurring monthly obligations like credit card minimums, car payments, student loans.
- Down Payment (DP): The upfront amount you can pay towards the home.
- Loan Term (N): The duration of your mortgage (e.g., 15, 30 years).
- Interest Rate (R): The annual interest rate for the loan.
- Property Taxes (PT): Annual property tax amount.
- Homeowner's Insurance (HI): Annual homeowner's insurance premium.
- HOA Fees (HOA): Monthly Homeowners Association fees (if applicable).
The calculation then reverses the standard mortgage payment formula M = P [ i(1 + i)n ] / [ (1 + i)n – 1] to find P (Principal Loan Amount), where M is your maximum affordable monthly P&I, i is the monthly interest rate (R/12/100), and n is the total number of monthly payments (N*12).
