What is a HELOC and How is it Calculated?
A Home Equity Line of Credit (HELOC) is a revolving line of credit that allows homeowners to borrow against the equity they have built in their property. Unlike a standard home equity loan, which provides a lump sum, a HELOC works more like a credit card with your home serving as collateral.
How the HELOC Formula Works
To determine your credit limit, lenders use the Combined Loan-to-Value (CLTV) ratio. The basic formula used in this calculator is:
(Home Value × Max CLTV Percentage) – Current Mortgage Balance = HELOC Limit
For example, if your home is worth $400,000 and your lender allows an 85% CLTV:
- 85% of $400,000 is $340,000.
- If you owe $250,000 on your primary mortgage, you subtract that from $340,000.
- Your estimated HELOC limit would be $90,000.
Key Factors Influencing Your HELOC
- Credit Score: Higher scores often grant access to higher CLTV percentages (up to 90%) and lower interest rates.
- Debt-to-Income (DTI) Ratio: Lenders look at your monthly income versus your monthly debt obligations to ensure you can handle the payments.
- Property Appraisal: While you may estimate your home's value, a professional appraisal will be required by the lender to finalize the limit.
- Variable Interest Rates: Most HELOCs have variable rates, meaning your monthly payments can fluctuate based on market conditions.
When to Use a HELOC
Homeowners frequently use HELOCs for high-impact financial needs such as home renovations (which may offer tax advantages), debt consolidation, or emergency expenses. Because the interest rates are generally lower than personal loans or credit cards, it is a cost-effective way to access large sums of capital.
