Understanding Your HELOC Limit
A Home Equity Line of Credit (HELOC) is a revolving credit line secured by your home. Unlike a traditional home equity loan, which provides a lump sum, a HELOC allows you to borrow as needed up to a certain limit, much like a credit card with lower interest rates.
How the HELOC Formula Works
Lenders don't let you borrow against the full value of your home. They use a metric called Loan-to-Value (LTV) ratio. Most lenders cap the combined loan-to-value (CLTV) at 80% to 85%.
The Formula:
(Home Value × Max LTV%) – Current Mortgage Balance = Available HELOC Limit
(Home Value × Max LTV%) – Current Mortgage Balance = Available HELOC Limit
Calculation Example
Let's say your home is valued at $400,000 and your current mortgage balance is $200,000. If a lender allows an 80% LTV:
- Step 1: $400,000 × 0.80 = $320,000 (Maximum total debt allowed)
- Step 2: $320,000 – $200,000 (Current debt) = $120,000 HELOC Limit
Factors That Affect Your HELOC Approval
While equity is the most important factor, lenders will also look at:
- Credit Score: A score of 720+ typically secures the best interest rates.
- Debt-to-Income (DTI) Ratio: Lenders prefer a DTI below 43%.
- Appraisal: A professional appraisal will confirm the actual market value of your property.
- Income Stability: Proof of consistent employment and income.
