Example of HELOC Calculation
Let’s understand how the calculator works with a real-life example:
- Home Value: $300,000
- Mortgage Balance: $120,000
- LTV Ratio: 80%
- Interest Rate: 6%
Step 1: Maximum Borrowing Limit
300,000 × 80% = $240,000
Step 2: Available Credit
240,000 − 120,000 = $120,000
Step 3: Total Home Equity
300,000 − 120,000 = $180,000
Step 4: Monthly Interest Estimate
(120,000 × 6%) ÷ 12 = $600/month
Final Output:
- Maximum Borrowing Limit: $240,000
- Available Credit: $120,000
- Home Equity: $180,000
- Monthly Interest: $600
