What Is Home Equity? How It Works & How to Calculate It

If you are asking what is home equity, the simplest answer is this: home equity is the difference between what your home is currently worth and what you still owe on debt secured by the property.

For example, if your home is worth about $400,000 and you owe $275,000 on the mortgage, you have about $125,000 in estimated home equity. That number can rise as you pay down principal or as the property’s value increases. It can also fall if the home’s value declines or if you add more debt secured by the home.

The basic idea is simple, but homeowners often confuse home equity with home value, cash, sale proceeds, or the amount they may be able to borrow. Understanding those differences makes the number much more useful.

What Is Home Equity?

Home equity is the portion of your home’s current value that is not offset by debt secured by the property.

The Consumer Financial Protection Bureau defines equity as the amount a property is currently worth minus the amount of the existing mortgage. For a homeowner with more than one loan secured by the property, a practical equity estimate should account for the outstanding balances of those secured debts.

A simple formula is estimated home equity = current estimated home value – outstanding debt secured by the home

Home equity is usually expressed in dollars, but you can also express it as a percentage of the home’s value.

It is important not to describe the lender as “owning the rest of the house.” A mortgage gives the lender a security interest connected to the loan. The homeowner’s equity is a financial measure of value minus secured debt, not a simple ownership split between homeowner and lender.

How Does Home Equity Work?

Home equity changes because both sides of the equation can change:

1. The amount your home is worth.
2. The amount you owe on debt secured by the home.

That means your equity can move even when you do nothing unusual. A regular mortgage payment may reduce principal. Local market conditions may push property values up or down. A new loan secured by the property may increase the amount of debt against the home.

A useful way to think about equity is as a moving financial position rather than a fixed balance stored somewhere.

Starting estimated equity position

+ principal reduction
+/− changes in property value
− additional outstanding debt secured by the home
= current estimated home equity

This framework also helps separate four ideas that are often confused:

Home value is not the same as home equity. Home equity is not the same as borrowing capacity. Borrowing capacity is not the same as cash in your bank account.

Your Down Payment Creates an Initial Equity Position

When you buy a home with a mortgage, your down payment generally creates an initial equity position because you are borrowing less than the full purchase amount.

Suppose a home is purchased for $300,000 and the buyer makes a $60,000 down payment. If the mortgage begins at $240,000 and the property’s value is approximately $300,000, the buyer starts with roughly $60,000 of equity under that simplified calculation.

That does not mean every dollar paid at closing becomes equity. Closing costs, prepaid expenses, taxes, insurance, and other transaction charges are separate from the amount that reduces the purchase price being financed.

If you recently bought a home, our new homeowner checklist covers the broader financial, document, insurance, maintenance, and property-record tasks that begin after closing.

Paying Down Mortgage Principal Can Increase Equity

As you repay mortgage principal, the outstanding loan balance decreases. If the home’s value stays the same, a lower mortgage balance means more equity.

The distinction between principal and interest matters. According to the CFPB’s explanation of mortgage repayment, the portion of a payment applied to principal reduces what you owe and builds equity. The interest portion does not reduce the loan balance.

Early in a typical amortizing mortgage, a larger share of the principal-and-interest payment may go toward interest. Over time, more of the scheduled payment generally goes toward principal as the balance declines.

So it would be inaccurate to add up all of your mortgage payments and treat that total as equity.

Changes in Home Value Can Increase or Decrease Equity

Equity also changes when the property’s market value changes.

If your mortgage balance stays at $275,000 while the home’s estimated value rises from $400,000 to $425,000, estimated equity rises from $125,000 to $150,000.

If the home’s estimated value instead falls to $360,000, estimated equity falls to $85,000 even though the mortgage balance has not changed.

Freddie Mac’s home equity guidance explains that homeowners can build equity through principal repayment and changes in property value. The same logic works in reverse when property values decline.

How to Calculate Your Home Equity

You can estimate your home equity with three basic pieces of information:

1. Your home’s current estimated value.
2. The current balance of your mortgage.
3. The outstanding balance of any additional debt secured by the property.

Then subtract the secured debt from the estimated value.

Step 1: Estimate Your Home’s Current Value

Your original purchase price is not necessarily your home’s current value.

You might begin with a recent market estimate, comparable sales, or other property-value information. But online estimates and homeowner calculations are not the same as a formal appraisal.

A professional appraisal is an independent opinion of property value prepared for a specific purpose. Our guide to the home appraisal process explains how appraisals work and why an appraised value may differ from a purchase price or an online estimate.

For a personal equity estimate, use a reasonable current value and remember that the result is still an estimate. Freddie Mac also describes its home equity calculator as a tool for guidance and financial estimates rather than a substitute for a lender’s precise calculation.

Step 2: Find the Balances of Loans Secured by the Home

Next, identify what you currently owe on debt secured by the property.

For many homeowners, that will be the unpaid principal balance of one mortgage. If there is another secured loan or an outstanding drawn balance on a home equity line of credit, that debt can also affect the homeowner’s net equity position.

Use current balances rather than the original loan amounts.

Do not subtract unsecured debts such as credit-card balances or auto loans from the home-equity calculation simply because they affect your overall finances. Home equity focuses on the home’s value relative to debt secured by the property.

Step 3: Subtract Secured Debt From the Home’s Value

Suppose:

• estimated home value = $400,000;
• current mortgage balance = $275,000; and
• there is no other outstanding debt secured by the property.

The calculation is $400,000 – $275,000 = $125,000 estimated home equity

If there were also a $20,000 outstanding balance on another loan secured by the home, the simplified equity estimate would become $400,000 – $275,000 – $20,000 = $105,000 estimated home equity

The formula is easy. The harder part is making sure the value estimate and loan balances are reasonably current.

How to Calculate Home Equity as a Percentage

To express equity as a percentage of the home’s estimated value:

Equity percentage = estimated equity ÷ estimated home value × 100

Using the $400,000 home and $125,000 equity example: $125,000 ÷ $400,000 × 100 = 31.25% equity

That means the estimated equity equals 31.25% of the home’s estimated value.

This percentage can help you understand your financial position, but it should not be treated as a promise that a lender will let you borrow that percentage or that you would receive that amount in cash after selling.

Home Equity Example: Dollar Amount and Percentage

Here is the same simplified example viewed from several angles:

The equity percentage and the simplified current loan-to-value estimate happen to add to 100% in this one-mortgage example because they are measuring opposite sides of the same estimated property value.

That relationship becomes more complicated when multiple liens or different lending calculations are involved, so do not use the simple example as a substitute for a lender’s underwriting calculation.

Home Equity vs. Home Value vs. Loan-to-Value Ratio

Home value, equity, and loan-to-value ratio are related, but they answer different questions.

The CFPB defines loan-to-value ratio in mortgage lending as a comparison between the amount being financed and the appraised value of the property. Lenders may use LTV when evaluating a mortgage and determining some loan terms or mortgage-insurance requirements. For an existing homeowner, dividing a current loan balance by an estimated current home value can provide a simplified current LTV estimate, but it is not a substitute for a lender’s own valuation and underwriting calculation.

In the simplified example:

• home value = $400,000;
• mortgage balance = $275,000;
• estimated equity = $125,000;
• equity percentage = 31.25%; and
• estimated current LTV = 68.75%.

A higher home value does not automatically mean a homeowner has more usable cash. It may mean the homeowner has more estimated equity, depending on the secured debt against the property.

What Can Increase or Decrease Your Home Equity?

The home-equity formula has two moving parts: value and debt. Anything that materially changes either side can change equity.

Mortgage Principal Payments

Scheduled principal payments reduce the mortgage balance.

If the property value stays the same, reducing principal increases equity dollar for dollar. Interest, property taxes, homeowners insurance, HOA charges, and similar expenses do not reduce the mortgage principal merely because they are part of your total housing cost.

Home Appreciation or Depreciation

If the home’s market value rises while secured debt stays the same, equity increases. If the home’s market value falls, equity decreases.

This is why equity can change even if you make every mortgage payment exactly as scheduled. Market conditions are outside an individual homeowner’s control.

Home Improvements and Property Condition

Improvements may affect a home’s value, but the amount spent is not automatically added to equity.

A $25,000 renovation does not guarantee a $25,000 increase in market value. The effect depends on the property, the quality and condition of the work, buyer preferences, local market conditions, and how the improvement is valued.

Routine maintenance can also matter indirectly because neglected systems or visible deterioration can affect property condition and buyer perceptions. Our home maintenance checklist can help homeowners organize recurring maintenance tasks without assuming every repair creates a matching increase in value.

Additional Debt Secured by the Home

Taking on more debt secured by the property can reduce your net equity position.

For example, if a homeowner with $125,000 of estimated equity later has a $30,000 outstanding balance on an additional secured loan, the homeowner’s estimated net equity would be lower if the property value and first-mortgage balance stayed unchanged.

A credit limit by itself is not the same as an outstanding balance. The amount actually owed is what matters to the simple equity calculation.

How to Build Equity in Your Home

Home equity can grow through debt reduction, value growth, or both. There is no guaranteed schedule because property values can move in either direction and mortgage structures differ.

Make Your Regular Mortgage Payments

For an amortizing mortgage, each scheduled payment typically includes some amount applied to principal.

That principal reduction gradually lowers what you owe. The amount going to principal may be smaller early in the loan and larger later, depending on the mortgage structure.

Pay Additional Principal When Appropriate

Some homeowners choose to make extra principal payments.

If extra money is applied to principal, it can reduce the balance faster and increase equity faster than scheduled principal payments alone, assuming the property value does not decline enough to offset the reduction.

Before making additional payments, check your loan terms and servicer instructions so you understand how the payment will be applied. A faster mortgage payoff is a financial decision that should fit your broader cash-flow, emergency-fund, debt, and savings priorities.

Maintain and Improve the Property Strategically

Keeping up with maintenance can help protect the property’s condition. Improvements may also increase market value in some cases.

But neither maintenance nor renovations should be treated as a guaranteed equity return. Spending money on the property is different from proving that the market value increased by the same amount.

Allow Time for Market Value to Change

Long-term property-value changes can become a significant part of homeowner equity, but appreciation is not guaranteed.

A rising market can increase equity even without renovations. A declining market can reduce equity despite regular mortgage payments.

The safest way to think about future appreciation is as a possible contributor to equity, not something a homeowner is entitled to receive.

Can Home Equity Go Down?

Yes. Home equity can decrease. The most direct causes are:

• the property’s value declines;
• debt secured by the home increases; or
• both happen at the same time.

For example, suppose a home is worth $300,000 and the mortgage balance is $260,000. The homeowner has about $40,000 in estimated equity.

If the property’s estimated value falls to $245,000 while the mortgage balance remains $260,000, the calculation becomes $245,000 – $260,000 = -$15,000. That is negative equity.

What Negative Equity Means

Negative equity means the debt secured by the home is greater than the property’s estimated current value.

You may also hear a mortgage described as “underwater” when the mortgage debt exceeds the property’s value.

Negative equity can matter if the homeowner needs to sell, refinance, or otherwise change the financing because the property’s value may not be enough to cover the secured debt.

This article does not attempt to cover foreclosure, short-sale, loss-mitigation, or distressed-selling options. Those situations involve additional financial, contractual, and sometimes legal considerations.

Total Home Equity vs. Available or Borrowable Equity

Having $100,000 of estimated equity does not mean you can withdraw $100,000.

Total equity is a calculation based on value and secured debt. How much a homeowner may be able to borrow depends on the loan product, the lender’s rules, and underwriting.

A lender may consider factors such as:

• the property’s value;
• existing mortgage and secured-loan balances;
• the resulting loan-to-value relationship;
• income;
• debts;
• credit history;
• the specific loan product; and
• other underwriting requirements.

The difference matters because homeowners sometimes think of equity as an account balance. It is not.

Home equity is an ownership-value measure. Turning part of it into cash generally requires a transaction, such as selling the property or qualifying for financing secured by the home.

What Can You Do With Home Equity?

Home equity can affect a homeowner’s choices, but the right use depends on the situation. Two common ways homeowners may convert some of that equity into cash are selling the home and qualifying for borrowing secured by the property.

Realize Equity When You Sell

When a home is sold, the sale proceeds are used to address amounts that must be paid at or through closing, including mortgage payoff and applicable transaction costs.

If money remains after those obligations and adjustments, the seller may receive net proceeds.

That is why equity is relevant to selling, but it is not the same thing as the check a seller receives at closing. Our guide to how to sell a house explains the broader sale process from preparation through closing.

Borrow Against Equity

Some financial products allow qualified homeowners to borrow using the home as collateral.

A home equity loan generally provides borrowed funds as a lump sum, while a home equity line of credit is a revolving line of credit.

Those are borrowing products, not simply withdrawals from an equity balance. They involve qualification, costs, repayment obligations, and risk. Because the home serves as collateral, failure to repay can put the home at risk.

This guide does not compare HELOCs, home equity loans, or cash-out refinances. Each is a separate financing decision that deserves product-specific evaluation.

Home Equity Is Not the Same as Your Sale Proceeds

A homeowner may estimate $150,000 of equity and assume that selling would produce a $150,000 check. That is not necessarily the case.

Estimated equity is usually a value-minus-debt calculation. Actual seller proceeds can also be affected by:

• the final sale price;
• mortgage and other lien payoffs;
• real estate compensation where applicable;
• seller concessions;
• title, escrow, attorney, recording, transfer, or closing charges where applicable;
• taxes and prorations;
• repair credits or negotiated adjustments; and
• other transaction-specific costs.

The property’s final sale price may also differ from the value estimate used in your equity calculation. So equity can be useful for planning, but it is not a substitute for a transaction-specific net-proceeds estimate.

Frequently Asked Questions About Home Equity

Does a Down Payment Count as Home Equity?

Generally, a down payment creates an initial equity position because it reduces how much of the purchase must be financed.

For example, if a $300,000 home is financed with a $240,000 mortgage and the property is worth approximately $300,000, the simplified starting equity is about $60,000.

Closing costs and prepaid expenses are separate and should not automatically be added to the equity figure.

Does Every Mortgage Payment Build the Same Amount of Equity?

No. For a typical amortizing mortgage, part of the payment goes to principal and part goes to interest. The principal portion reduces the balance and builds equity. The interest portion does not.

The principal share can change over the life of the loan.

How Much Equity Do I Have in My Home?

Start with a reasonable estimate of the home’s current value. Then subtract the current outstanding balances of debt secured by the property.

If a home is worth about $500,000 and the only secured debt is a $320,000 mortgage balance, estimated equity is approximately $500,000 – $320,000 = $180,000

Because the home’s value may be estimated, your equity calculation may also be an estimate.

Is Home Equity the Same as Cash?

No. Equity is value tied to the property. It is not a cash balance sitting in a bank account.

To convert equity into cash, a homeowner generally needs a transaction, such as selling the home or qualifying for borrowing secured by it. Either path can involve costs, restrictions, and risk.

Can Home Improvements Increase Home Equity?

They can, but an improvement does not automatically increase equity by the amount spent.

The improvement would need to increase the property’s market value, preserve value that might otherwise be lost, or contribute to another measurable value change.

Market response varies, so avoid treating renovation spending as guaranteed equity.

Can Home Equity Become Negative?

Yes. If the amount owed on debt secured by the home exceeds the property’s current value, the homeowner has negative equity.

That can happen after a substantial decline in property value, an increase in secured debt, or a combination of both.

Is Home Equity the Same as Home Value?

No. Home value is the estimated value of the entire property. Home equity is what remains after subtracting debt secured by the property.

A $500,000 home with $350,000 in secured debt has about $150,000 in estimated equity, not $500,000.

Is Home Equity the Same as Net Worth?

No, but home equity can be one component of net worth. Net worth considers a person’s broader assets and liabilities. Home equity focuses only on the relationship between a home’s value and debt secured by that property.

Someone may have substantial home equity but also have other debts, investments, savings, retirement accounts, vehicles, business interests, or other assets and liabilities that affect overall net worth.

Know What Your Home Equity Number Actually Means

The clearest answer to what is home equity is the difference between your home’s current value and the debt secured by it. But the useful part is understanding what makes that number move.

Principal repayment can increase equity by reducing what you owe. Property appreciation can increase equity by raising value. Depreciation can reduce it. Additional secured debt can reduce the amount of value that remains after debt.

Use a current value estimate and current loan balances when calculating your equity, and remember that the result is usually an estimate rather than cash you can automatically access.

Once you separate home value, secured debt, equity, borrowing capacity, and sale proceeds, home equity becomes a much clearer measure of your position as a homeowner.
