How to Calculate Home Equity: Complete Guide for 2026

Understanding how much equity you have in your home is crucial for making informed financial decisions. Whether you're considering a [home equity loan](/blog/best-heloc-lenders-2026), planning a refinance, or simply want to know your net worth, calculating your home equity is a straightforward process that every homeowner should master.

[What Is Home Equity](/blog/home-equity-explained)?

Home equity represents the portion of your property that you truly own. It's the difference between your home's current market value and the amount you still owe on your mortgage. As you pay down your mortgage and as your home appreciates in value, your equity grows.

Think of equity as your financial stake in your home. If you sold your house today and paid off all outstanding loans, the remaining money would be your equity.

The Basic Home Equity Formula

The formula for calculating home equity is simple:

Home Equity = Current Home Value - Outstanding Mortgage Balance

For example:

Current home value: $450,000
Remaining mortgage balance: $280,000
Home equity: $450,000 - $280,000 = $170,000

Step-by-Step Guide to Calculate Your Home Equity

Step 1: Determine Your Home's Current Market Value

Your home's current value may be significantly different from what you paid for it. Here are several methods to estimate it:

Professional Appraisal ($300-$600): The most accurate method. A licensed appraiser evaluates your home based on condition, location, recent improvements, and comparable sales.

Online Valuation Tools (Free): Websites like Zillow, Redfin, and Realtor.com provide automated estimates. While convenient, these can vary by 5-20% from actual value. Use multiple sources and average the results.

[Comparative Market Analysis](/blog/how-much-is-my-house-worth) (CMA) (Free): Ask a local real estate agent to prepare a CMA. They'll compare your home to similar properties recently sold in your neighborhood.

County Tax Assessment (Free): Check your property tax assessment, but note these are often lower than market value and may be outdated.

Best Practice: Use at least two methods and average the results for a more accurate estimate.

Step 2: Find Your Current Mortgage Balance

Your outstanding mortgage balance is not the same as your original loan amount. Here's how to find it:

Check Your Latest Mortgage Statement: Your monthly statement shows the current principal balance.

Log Into Your Lender's Online Portal: Most mortgage servicers provide 24/7 access to your current balance.

Call Your Lender: Customer service can provide your exact payoff amount.

Important: Use the principal balance only, not the total amount including interest for the remaining loan term.

Step 3: Account for Other Liens

If you have additional loans secured by your home, subtract these from your equity calculation:

Second mortgages
Home equity loans
Home equity lines of credit (HELOCs)
Tax liens
Mechanic's liens

Adjusted Formula: Home Equity = Current Home Value - All Mortgage Debt - Other Liens

Step 4: Calculate Your Equity Percentage

Your equity percentage helps determine what you can borrow and your financial position:

Equity Percentage = (Home Equity ÷ Current Home Value) × 100

Example:

Home equity: $170,000
Current home value: $450,000
Equity percentage: ($170,000 ÷ $450,000) × 100 = 37.8%

This also means your loan-to-value (LTV) ratio is 62.2% (100% - 37.8%).

Real-World Examples

Example 1: Recent Home Purchase

Sarah bought her home 2 years ago:

Purchase price: $350,000
Down payment: $70,000 (20%)
Original mortgage: $280,000
Current mortgage balance: $272,000
Current home value: $385,000 (10% appreciation)

Equity calculation: $385,000 - $272,000 = $113,000 Equity percentage: ($113,000 ÷ $385,000) × 100 = 29.4%

Sarah has built equity through both principal payments ($8,000) and appreciation ($35,000).

Example 2: Long-Term Homeowner

Michael has owned his home for 15 years:

Original purchase price: $200,000
Original mortgage: $160,000
Current mortgage balance: $68,000
Current home value: $475,000
HELOC balance: $25,000

Equity calculation: $475,000 - $68,000 - $25,000 = $382,000 Equity percentage: ($382,000 ÷ $475,000) × 100 = 80.4%

Michael has substantial equity from both principal paydown and significant appreciation.

Example 3: Underwater Mortgage

Unfortunately, some homeowners have negative equity:

Current home value: $280,000
Mortgage balance: $315,000

Equity calculation: $280,000 - $315,000 = -$35,000

This homeowner is "underwater" or "upside down" on their mortgage, owing more than the home is worth.

Factors That Affect Your Home Equity

Factors That Increase Equity

Mortgage Principal Payments: Every payment includes a portion that reduces your loan balance. Early in your mortgage, this is a small amount, but it increases over time as less interest is charged.

Home Value Appreciation: Market conditions, neighborhood improvements, and economic factors can increase your home's value. The national average appreciation is 3-5% annually, though this varies significantly by location.

Home Improvements: Strategic renovations can boost your home's value:

Kitchen remodels: 60-80% return on investment
Bathroom updates: 60-70% return
Adding square footage: 50-65% return
Landscaping improvements: 100%+ return (low cost, high impact)

Additional Principal Payments: Making extra payments directly toward principal accelerates equity building. An extra $200/month on a $300,000 mortgage at 6% can build an additional $50,000+ in equity over 10 years.

Factors That Decrease Equity

Market Decline: Economic downturns, neighborhood deterioration, or oversupply can reduce home values.

Home Equity Borrowing: Taking out a [HELOC or home equity loan](/blog/home-equity-loan-vs-heloc-2026) reduces your net equity.

Deferred Maintenance: Neglecting necessary repairs can decrease your home's value.

Natural Disasters: Significant damage without proper insurance can impact value.

How Much Equity Do You Need?

For a Home Equity Loan or HELOC

Most lenders require:

Minimum 15-20% equity to qualify
Combined loan-to-value (CLTV) ratio of 80-90% maximum

This means lenders typically let you borrow against up to 80-90% of your home's value, minus existing mortgage debt.

Example:

Home value: $400,000
Maximum CLTV: 85%
Maximum total debt: $400,000 × 0.85 = $340,000
Current mortgage: $250,000
Maximum HELOC: $340,000 - $250,000 = $90,000

For Refinancing

To avoid [private mortgage insurance](/blog/mortgage-insurance-pmi-guide) (PMI) when refinancing:

Conventional loans: Minimum 20% equity
FHA streamline refinance: No minimum equity
VA Interest Rate Reduction Refinance Loan (IRRRL): No minimum equity

For Selling

When selling, you need enough equity to cover:

Real estate agent commissions (5-6% of sale price)
Closing costs (1-3% of sale price)
Remaining mortgage balance
Moving expenses

Example:

Sale price: $450,000
Agent commission (6%): $27,000
Closing costs (2%): $9,000
Mortgage payoff: $280,000
Net proceeds: $450,000 - $27,000 - $9,000 - $280,000 = $134,000

Common Mistakes to Avoid

Using Outdated Home Values: Real estate markets change constantly. Values from 2-3 years ago may no longer be accurate.

Forgetting Selling Costs: Your equity isn't entirely liquid. Factor in 7-9% for selling expenses.

Ignoring Additional Liens: Always account for all debts secured by your home.

Confusing Equity with Cash: Equity is theoretical until you sell or borrow against it. It's not liquid like savings.

Over-Improving: Not all renovations return their cost. Research ROI before major projects.

Assuming Linear Appreciation: Markets fluctuate. Don't count on continuous appreciation.

Frequently Asked Questions

How often should I calculate my home equity?

Review your equity annually at minimum, or quarterly if you're actively monitoring it for a specific financial goal. Recalculate before major financial decisions like taking out a loan or refinancing.

Does paying property taxes increase my equity?

No. Property taxes are separate from your mortgage and don't increase your ownership stake. However, failing to pay property taxes can result in a tax lien, which would reduce your equity.

Can I have negative equity?

Yes, this happens when you owe more than your home is worth. This is called being "underwater" or "upside down." It can occur due to market declines, high-LTV loans, or taking out additional debt against the home.

How much equity do most homeowners have?

According to recent data, the average American homeowner has approximately $200,000-$300,000 in home equity. However, this varies dramatically by region, how long you've owned the home, and market conditions.

Does refinancing affect my equity?

Refinancing itself doesn't change your equity, but it can affect it indirectly. A cash-out refinance decreases equity by increasing your loan balance. A standard rate-and-term refinance maintains your equity level while potentially lowering payments.

How do I increase my equity faster?

Make extra principal payments, improve your home strategically, maintain your property well, and benefit from market appreciation. Even one extra mortgage payment per year can significantly accelerate equity building.

Is home equity considered an asset?

Yes, home equity is a major component of net worth. However, it's an illiquid asset—you can't spend it directly without selling the home or borrowing against it.

What's the difference between equity and appraisal value?

Appraisal value is your home's total worth. Equity is the portion you own (appraisal value minus debts). If your home appraises at $400,000 and you owe $250,000, your equity is $150,000.
