Home Equity Line of Credit Calculator Interested in a HELOC but not sure what amount you qualify for? Find out using our simple calculator. Pro tip: Your line of credit will be based on a percentage of the value of your home — the more your home is worth, the larger the line of credit. Information and interactive calculators are made available to you only as self-help tools for your independent use and are not intended to provide actual loan details or provide investment/tax advice. We encourage you to seek personalized advice from a Connexus representative regarding all personal finance issues.
