How to Use

1. Enter your home's current value and your remaining mortgage balance.
2. We show your equity, loan-to-value, and how much you may be able to borrow via a HELOC.

Calculation Method

Equity = current value − mortgage balance. LTV = balance ÷ value. HELOC availability is estimated as (value × 85% combined LTV) − current balance, a common lender cap.

Data sources: Standard equity/LTV definitions; HELOC limit at a typical 85% combined LTV.

Examples

$500,000 value, $300,000 owed

Equity $200,000, LTV 60%, potential HELOC up to about $125,000 at 85% combined LTV.
