Home equity is a crucial financial metric for homeowners. It represents the portion of your home's value that you truly own, free and clear of any debts or liens against it. In simple terms, it's the difference between your home's current market value and the total amount you owe on it.
The Formula for Home Equity
Calculating home equity is straightforward. The core formula is:
Home Equity = Current Market Value of Home – Total Outstanding Debt Secured by the Home
To break this down further, the "Total Outstanding Debt Secured by the Home" includes:
The remaining balance on your primary mortgage.
The total balance of any other loans or liens recorded against your property, such as a home equity loan, a home equity line of credit (HELOC), or any other second mortgages.
Why is Home Equity Important?
Understanding your home equity is vital for several reasons:
Refinancing: Lenders often look at your loan-to-value (LTV) ratio, which is directly related to your equity, when considering refinancing options. Higher equity can lead to better interest rates and terms.
Home Equity Loans & HELOCs: If you need to borrow money for renovations, education, or other major expenses, your home equity can serve as collateral. The amount you can borrow is typically a percentage of your equity.
Selling Your Home: Your equity influences the net proceeds you'll receive after paying off mortgages and selling costs.
Financial Health: Tracking your equity over time can be an indicator of your overall financial progress and wealth building.
Factors Affecting Home Equity
Several factors can influence how your home equity changes:
Property Value Appreciation/Depreciation: As the real estate market fluctuates, your home's market value can increase or decrease, directly impacting your equity.
Mortgage Payments: Each mortgage payment you make reduces your outstanding loan balance, thereby increasing your equity.
Taking Out New Loans: Obtaining a home equity loan or HELOC increases your total debt secured by the home, reducing your equity.
How to Use This Calculator
To determine your home equity using this calculator, please provide the following information:
Current Market Value of Home: This is an estimate of what your home would sell for today. You can get this from recent appraisals, comparative market analyses (CMAs) from real estate agents, or online valuation tools.
Total Outstanding Mortgage Balance: This is the current principal amount you still owe on your primary mortgage. Check your latest mortgage statement.
Total of Other Liens/Loans: Sum up the outstanding balances on any other debts that are secured by your home, such as HELOCs or second mortgages.
After entering these figures, click "Calculate Equity" to see your estimated home equity.
