Buying a home is one of the largest financial commitments most people make in their lifetime. One of the most important questions before starting your home search is: “How much mortgage can I afford?”
The Mortgage Afford Calculator helps homeowners and prospective buyers determine how much house they can realistically purchase based on monthly income, expenses, interest rates, and loan term. By using this tool, you can make informed financial decisions and avoid overextending your budget.
Formula
The calculator uses two main calculations:
1. Affordable Payment Calculation
Affordable Payment = (Monthly Income × 28%) − Monthly Expenses
This follows the common “28% rule,” which suggests you should spend no more than 28% of your gross monthly income on housing costs.
2. Maximum Mortgage Loan Calculation
Maximum Loan = Affordable Payment × (1 − (1 + r)^−n) ÷ r
Where:
- r = monthly interest rate (annual ÷ 12)
- n = total number of monthly payments (loan term × 12)
How to Use the Calculator
- Enter your monthly income (before taxes).
- Enter your monthly expenses (utilities, insurance, debt payments, etc.).
- Enter the annual interest rate of the mortgage.
- Enter the loan term in years (commonly 15, 20, or 30).
- Click Calculate.
- The calculator will display:
- Estimated affordable monthly payment
- Maximum mortgage amount you can afford
Example
Suppose your monthly income is $5,000, monthly expenses are $1,000, interest rate is 6%, and loan term is 30 years.
Step 1: Affordable monthly payment = (5000 × 0.28) − 1000 = $400.
Step 2: Monthly interest rate = 6% ÷ 12 = 0.005
Step 3: Loan term = 30 × 12 = 360 payments
Step 4: Maximum mortgage = 400 × (1 − (1.005)^−360) ÷ 0.005 ≈ $74,000
So, you can afford a home loan of about $74,000, with a monthly payment around $400.
