About the HELOC Calculator

A home equity line of credit (HELOC) lets you borrow against the equity in your home, up to a lender's maximum combined loan-to-value (CLTV) limit across your mortgage and the new line of credit.

Formula: Available HELOC = (Home Value × Max CLTV%) − Existing Mortgage Balance

Lenders commonly cap combined borrowing at 80-90% of home value, the exact limit depends on your credit profile and the lender's specific guidelines.
