Practical Example of HELOC Calculation

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

Input Values:

• Home Value: $300,000
• Mortgage Balance: $180,000
• LTV: 85%
• Interest Rate: 8.5%
• Draw Amount: $20,000
• Term: 10 years

Step-by-Step Results:

1. Available Equity

$300,000 − $180,000 = $120,000

2. Maximum Credit Line

($300,000 × 85%) − $180,000 = $75,000

3. Monthly Interest-Only Payment

Based on draw amount: ≈ $141.67/month

4. Draw Utilization

($20,000 ÷ $75,000) × 100 = 26.7%

5. Recommendation

“Moderate credit line, use responsibly.”
