About Home Equity Calculator
The Home Equity Calculator calculates your current net property equity by subtracting all outstanding mortgage and lien balances from your home's current fair market value.
Formula & Mathematical Calculation
Home Equity ($) = Current Market Value - Total Remaining Mortgage Balances
Equity Percentage = ( Home Equity / Current Market Value ) × 100
Usable Equity (80% LTV Limit) = ( Current Market Value × 0.80 ) - Total Mortgage Balances
Calculation Example
Example: Home Value: $450,000 | 1st Mortgage Balance: $250,000 → Total Equity = $200,000 (44.4%). Usable Equity @ 80% LTV = $110,000.
