Your Estimated HELOC Limit
What is a HELOC?
A Home Equity Line of Credit (HELOC) is a revolving line of credit that uses your home as collateral. Unlike a standard home equity loan, which provides a lump sum, a HELOC allows you to borrow against your equity as needed, similar to a credit card but with typically much lower interest rates.
How Your HELOC Limit is Calculated
Lenders generally use a specific formula to determine how much you can borrow. This is based on your "Combined Loan-to-Value" (CLTV) ratio. Most lenders limit this ratio to 80% or 85% of your home's appraised value.
The Formula:
(Market Value of Home × Maximum LTV %) – Existing Mortgage Balances = Available HELOC Limit
Calculation Example:
Suppose your home is worth $400,000 and your lender allows an 85% LTV.
1. $400,000 × 0.85 = $340,000 (Maximum total debt allowed).
2. If you owe $250,000 on your primary mortgage, subtract that from the max debt.
3. $340,000 – $250,000 = $90,000 Potential HELOC.
Suppose your home is worth $400,000 and your lender allows an 85% LTV.

2. If you owe $250,000 on your primary mortgage, subtract that from the max debt.
3. $340,000 – $250,000 = $90,000 Potential HELOC.
Factors That Influence Your HELOC Approval
- Credit Score: Higher scores usually unlock lower interest rates and higher LTV limits.
- Debt-to-Income (DTI) Ratio: Lenders want to ensure you can afford the monthly interest-only or principal-and-interest payments.
- Home Appraisal: A professional appraisal will determine the official value used in the calculation.
