Example Calculation

Let’s understand how this works with a real-life example:

Monthly Income: $5,000
Monthly Debt: $500
Interest Rate: 6%
Loan Term: 30 years

Step 1: Calculate Maximum Monthly Payment

Typically, lenders recommend spending no more than 28% of your income on housing.

28% of $5,000 = $1,400

Subtract debt:
$1,400 − $500 = $900

So, your maximum monthly mortgage payment is $900.

Step 2: Calculate Loan Amount

Based on the interest rate and loan term, the calculator estimates:

👉 Affordable Loan Amount ≈ $150,000 – $170,000 (approximate range)

This gives you a realistic budget for house hunting.
