Practical Example of HELOC Calculation

Let’s understand how the calculator works with a real-world example:

Input Details:

• Home Value: $400,000
• Mortgage Balance: $150,000
• Interest Rate: 7.5%
• Draw Amount: $50,000
• Loan Term: 20 years
• Monthly Income: $6,000

Step-by-Step Results:

1. Available Equity
$400,000 - $150,000 = $250,000

2. Maximum Credit Line (80%)
$250,000 × 80% = $200,000

3. Monthly Interest Cost
Approximately $312.50

4. Total Repayment Estimate
$50,000 + interest over time ≈ $125,000 (approx.)

5. Debt-to-Income Ratio (DTI)
About 5.2%

6. Approval Status
✔ Approved (Low Risk)

Final Insight:

The borrower qualifies easily since the requested draw is below the maximum limit and DTI is low.
