Understanding Your Home Equity Line of Credit (HELOC)

A Home Equity Line of Credit, or HELOC, functions much like a credit card secured by your home. It provides you with a revolving credit line that you can draw from as needed, pay back, and draw from again during the "draw period."

How the HELOC Calculation Works

Lenders determine your maximum credit limit based on your Combined Loan-to-Value (CLTV) ratio. Here is the standard formula used in this calculator:

(Home Value × Max CLTV %) – Current Mortgage Balance = Your HELOC Limit

Example Calculation

Suppose your home is worth $450,000 and your current mortgage balance is $300,000. If your bank allows an 85% CLTV:

• Step 1: $450,000 × 0.85 = $382,500 (Total borrowing power)
• Step 2: $382,500 – $300,000 = $82,500 Available Credit

Key Factors That Impact Your Approval

1. Credit Score: Most lenders require a score of 680 or higher for the best rates and higher CLTV limits.
2. Debt-to-Income (DTI) Ratio: Lenders evaluate your monthly gross income against your monthly debt obligations. A DTI below 43% is typically preferred.
3. Home Appraisal: While online estimates provide a baseline, a professional appraisal will be required to confirm the actual market value.

Draw Period vs. Repayment Period

Most HELOCs have two distinct phases:

• The Draw Period (typically 10 years): You can borrow money and usually have the option to make interest-only payments.
• The Repayment Period (typically 20 years): You can no longer borrow money, and you must pay back both the principal and the interest, which can significantly increase your monthly payment.

Note: HELOC interest rates are usually variable, meaning your monthly payment can fluctuate based on market conditions (the Prime Rate). Always check with your financial institution for current rates and terms.
