Understanding Your Home Equity Line of Credit (HELOC)

A Home Equity Line of Credit, or HELOC, is a revolving line of credit that uses your home as collateral. Think of it like a credit card with a much lower interest rate, where your limit is determined by the equity you have built in your property.

How Your HELOC Limit is Calculated

Lenders typically allow you to borrow up to a specific Combined Loan-to-Value (CLTV) ratio, often 80% to 85% of your home's current market value. The calculation follows this standard logic:

1. Determine your home's current appraised value.
2. Multiply that value by the lender's LTV limit (e.g., 80%).
3. Subtract your existing primary mortgage balance.
4. The remaining amount is your maximum credit line.

Example HELOC Calculation

Suppose your home is worth $500,000 and you owe $300,000 on your mortgage. If a lender allows an 85% CLTV:

• 85% of $500,000 = $425,000
• $425,000 – $300,000 (Current Balance) = $125,000 HELOC Limit

Key HELOC Terms to Know

• Draw Period: The timeframe (usually 5-10 years) during which you can withdraw money and typically make interest-only payments.
• Repayment Period: The timeframe (often 10-20 years) after the draw period ends where you must pay back both principal and interest.
• Variable Rate: Unlike a standard home equity loan, HELOCs usually have variable interest rates tied to the Prime Rate.
• Equity: The difference between what your home is worth and what you owe on all loans secured by the property.

HELOC vs. Home Equity Loan

While both use your home as collateral, a Home Equity Loan provides a lump sum with a fixed interest rate. A HELOC provides a flexible line you can use, repay, and reuse as needed, making it ideal for ongoing projects like home renovations or managing fluctuating expenses.
