Example Calculation
Let’s look at a real-world example to understand how the calculator works:
- Monthly Income: $5,000
- Monthly Debt: $500
- Interest Rate: 6%
- Loan Term: 30 years
Step 1: Calculate Maximum Monthly Payment
Using the standard 36% affordability rule:
36% of $5,000 = $1,800
$1,800 − $500 debt = $1,300
So, your maximum monthly mortgage payment is $1,300.
Step 2: Estimate Loan Amount
Based on the interest rate and loan term, the calculator estimates your loan amount to be approximately:
👉 $215,000 – $230,000 (approx.)
This gives you a realistic budget for house hunting.
Understanding the 36% Rule
The calculator uses a widely accepted guideline known as the 36% rule.
- No more than 36% of your income should go toward total debt
- This includes mortgage and existing debts
This rule ensures you maintain a healthy financial balance and avoid overextending yourself.
