Home Equity Calculator
Calculate your current home equity from market value and outstanding mortgage balance. Enter values for instant results with step-by-step formulas.
Formula
Home Equity = Home Value - Mortgage Balance - Other Liens | LTV = Mortgage / Value × 100
Home equity is your ownership stake. Most HELOCs allow borrowing up to 80-85% LTV. Equity below 20% typically requires PMI.
