Example Calculation
Let’s walk through a practical example to understand how the calculator works:
- Monthly Income: $5,000
- Monthly Debt: $500
- Interest Rate: 6%
- Loan Term: 20 years
Step 1: Calculate Max Monthly Payment
Typically, lenders allow up to 28% of income for housing:
- 28% of $5,000 = $1,400
- Subtract debt: $1,400 − $500 = $900
So, your maximum monthly mortgage payment is $900
Step 2: Estimate Loan Amount
Using the interest rate and loan term, the calculator estimates:
- Loan Amount ≈ $125,000 – $140,000 (approximate range depending on rate)
This gives you a realistic idea of your home buying budget.
