Equity is what you actually own of an asset after subtracting what you still owe against it. If your home is worth $400,000 and the mortgage balance is $250,000, your equity is $150,000. That single number shapes a lot of real decisions: how much you can borrow, what you walk away with at a sale, whether you can drop mortgage insurance, how a bankruptcy court treats your house, and how much wealth you’re actually building month to month. The same idea shows up in business ownership and stock compensation, but for most households the stakes are highest at home.
Where the Word Shows Up
Home Equity
Home equity is the gap between your home’s current market value and everything you owe on loans secured by it. Most Americans build the majority of their household wealth this way. When you buy a house with a mortgage, the lender places a lien on the property, and every principal payment shifts a little more ownership from the bank to you.1Consumer Financial Protection Bureau. What Is a Second Mortgage Loan or Junior-Lien Over a 30-year loan, early payments go mostly toward interest, so equity builds slowly at first and picks up speed later.
Shareholder Equity
In a company, equity is the ownership stake in the business. On a balance sheet it equals total assets minus total liabilities. The figure includes what investors paid for shares plus profits the company kept rather than distributing as dividends. If the business sold every asset and paid every creditor, shareholder equity is what would theoretically be left for stockholders.
Equity Compensation
Employers often grant equity as part of pay, usually through stock options or restricted stock units (RSUs). These grants almost always come with a vesting schedule that controls when you actually own the shares. A common structure is four years with a one-year cliff: nothing if you leave in the first twelve months, then shares on a regular schedule after that. Options give you the right to buy shares at a fixed price; RSUs convert directly into shares once vested.
How to Calculate Your Equity
The formula is simple: current fair market value minus all outstanding debt against the asset.
For a home, fair market value is the price a willing buyer would pay today. A professional residential appraisal typically runs $350 to $550, though large or unusual properties cost more. Free online valuation tools give you a starting point but can be off by 5% to 10% in neighborhoods without many recent sales.
For the debt side, use the exact payoff balance, not the balance on your monthly statement. Those figures differ. Federal law requires your mortgage servicer to send an accurate payoff figure within seven business days of receiving a written request.2Office of the Law Revision Counsel. United States Code Title 15 – 1639g Requests for Payoff Amounts of Home Loan Add in any second mortgage or home equity line. What remains after subtracting every lien is your equity.
Combined Loan-to-Value
Lenders use combined loan-to-value (CLTV) to decide how much more your home can support. It’s every loan secured by the property divided by the appraised value. If your home appraises at $400,000 and you owe $280,000, your LTV is 70%. A $40,000 home equity line would push CLTV to 80%. Most lenders cap CLTV at 85% on home equity lines, which means they expect you to keep at least 15% equity untouched as a cushion.
How Equity Grows
Equity moves through two channels: paying down debt and rising market value. Both can work at the same time, which is what makes homeownership a wealth-building tool when the math cooperates.
Debt reduction happens every time you make a mortgage payment that includes principal. The share going to principal starts small and grows over time. One extra payment a year on a 30-year mortgage can shave several years off the loan and build equity noticeably faster.
Appreciation is the increase in market value driven by broader economic conditions, neighborhood development, or improvements you make. A rising housing market can add tens of thousands in equity without any effort on your part. Targeted renovations like a kitchen update or an added bathroom can push appraised value higher, though not every improvement returns its full cost. Businesses build equity the same way: growing assets, improving profits, and keeping earnings rather than paying them out.
When Equity Goes Negative
Negative equity means you owe more than the property is currently worth. It happens when market values drop while your balance stays high, and it trapped millions of homeowners during the 2008 housing crisis. Being underwater doesn’t trigger any immediate legal problem as long as you keep paying, but the practical consequences are real.
You can’t sell without bringing cash to closing to cover the shortfall. Refinancing to a lower rate becomes nearly impossible because no lender wants to issue a new loan larger than the collateral. If you have to relocate, you’re choosing between absorbing the loss, attempting a short sale where the lender agrees to accept less than the full balance, or walking away and accepting the credit damage that follows.
The most reliable path out is patience combined with continued payments. Markets tend to recover, and every principal payment chips away at the gap. If your situation is urgent, contact your servicer about modification options before you miss a payment. Once you’re behind, options shrink fast.
Turning Equity Into Cash
Selling
The most direct way to convert equity into money is to sell. At closing, proceeds first pay off every lien, and you receive what’s left. Seller closing costs take more than most people expect. Agent commissions have historically run 3% to 6% of the sale price, and title insurance, transfer taxes, escrow fees, and prorated property taxes add to the bill. Budget for these before estimating what you’ll actually pocket.
Home Equity Line of Credit
A HELOC lets you borrow against your equity on a revolving basis, similar to a credit card but secured by your home.3Consumer Financial Protection Bureau. What You Should Know About Home Equity Lines of Credit The lender places a junior lien that sits behind your first mortgage in repayment priority. You draw what you need during a set period, typically 10 years, and then enter a repayment phase. Rates are usually variable, so monthly costs can climb if rates rise. If you can’t repay, the lender can foreclose.
Cash-Out Refinancing
A cash-out refinance replaces your existing mortgage with a new, larger loan, and you take the difference in cash. The appeal is a single payment, often at a fixed rate. The drawback is restarting your amortization clock, potentially paying closing costs a second time, and increasing what’s secured by your home. This tends to make sense only when the new rate is favorable and the use of the cash justifies the cost.
Reverse Mortgage
Homeowners aged 62 or older who own their home outright or hold substantial equity can convert some of that equity into income through a Home Equity Conversion Mortgage (HECM), the federally insured reverse mortgage program.4Congress.gov. HUD’s Reverse Mortgage Insurance Program: Home Equity Conversion Mortgage Instead of paying the lender, the lender pays you. The loan balance grows over time and comes due when you sell, move out permanently, or die. HUD requires counseling with an approved agency before you close, and lenders run a financial assessment to confirm you can keep up with property taxes and homeowner’s insurance. A HECM can provide real relief in retirement, but it reduces what your heirs inherit and carries significant upfront fees.
Equity and Private Mortgage Insurance
Private mortgage insurance (PMI) is an extra monthly cost lenders require when you put less than 20% down on a conventional loan. It protects the lender, not you. The Homeowners Protection Act gives you two paths to end it.5Federal Deposit Insurance Corporation. Homeowners Protection Act
- Borrower-requested cancellation. Once your balance is scheduled to reach 80% of the home’s original purchase price, you can submit a written request. You must be current, have a good payment history, show no subordinate liens, and confirm the home hasn’t lost value.6Office of the Law Revision Counsel. United States Code Title 12 – 4901 Definitions
- Automatic termination. Your servicer must cancel PMI when the balance is scheduled to reach 78% of the original value, provided you’re current. If you’re behind at that point, termination kicks in the first month after you catch up.7Office of the Law Revision Counsel. United States Code Title 12 – 4902 Termination of Private Mortgage Insurance
The detail people miss: both thresholds use the original purchase price, not the current appraised value. If your home has appreciated, you may still be able to request cancellation earlier by paying for a new appraisal that shows you’ve reached 80% LTV against current value. Check your servicer’s process, since some require at least two years of ownership before accepting an appraisal-based cancellation.
How Taxes Treat Equity
Selling Your Home
Federal law lets you exclude a large chunk of profit when you sell your primary residence. Single filers can exclude up to $250,000 in capital gains; married couples filing jointly can exclude up to $500,000.8Office of the Law Revision Counsel. United States Code Title 26 – 121 Exclusion of Gain From Sale of Principal Residence To qualify, you must have owned and used the home as your principal residence for at least two of the five years before the sale.9Internal Revenue Service. Sale of Your Home You can only claim the exclusion once every two years. For most homeowners this means home equity growth up to those thresholds is effectively tax-free. If you’ve owned for decades in a strong market, gain above the limit is taxed as a capital gain.
Mortgage Interest Deduction
Mortgage interest can be deductible, but the rules limit both the type of debt and the amount. For 2026, you can deduct interest on up to $750,000 of acquisition debt ($375,000 if married filing separately) used to buy, build, or substantially improve your home.10Office of the Law Revision Counsel. United States Code Title 26 – 163 Interest Interest on home equity debt used for other purposes, like paying off credit cards or funding a vacation, is not deductible.11Internal Revenue Service. Publication 936 – Home Mortgage Interest Deduction Use a HELOC to renovate your kitchen and the interest qualifies. Use the same HELOC to buy a boat and it doesn’t.
Stock Options and RSUs
Equity compensation creates taxable events when shares are exercised or vested. RSUs are taxed as ordinary income at their market value on the vesting date. Options are taxed differently depending on whether they’re incentive stock options (ISOs) or non-qualified stock options (NQSOs). With NQSOs, you owe ordinary income tax on the spread between the exercise price and the market price when you exercise. ISOs receive more favorable treatment but can trigger the alternative minimum tax. Selling shares later creates a separate capital gains event. This layered taxation catches people off guard, particularly at companies that go public or get acquired.
What Bankruptcy Protects
Filing for bankruptcy doesn’t automatically mean losing your home or all of your equity. Federal law provides a homestead exemption that protects $31,575 of equity in your principal residence from creditors. Married couples filing jointly can double that.12Office of the Law Revision Counsel. United States Code Title 11 – 522 Exemptions These figures apply to cases filed between April 1, 2025, and March 31, 2028, and are adjusted every three years for inflation.
Many states offer their own homestead exemptions, some far more generous than the federal amount, and a handful allow unlimited protection. Depending on where you live, you may be required to use your state’s exemption or given the choice between state and federal. If your equity exceeds the applicable exemption, a Chapter 7 trustee can force a sale to pay creditors, though the exempted portion still goes to you. In Chapter 13, you keep the property but must pay creditors at least what they would have received in a Chapter 7 liquidation, so high equity translates to higher required plan payments.
Equity in other assets gets some protection too. The federal system includes a wildcard exemption of $1,675, plus up to $15,800 of any unused homestead exemption, applicable to any property you choose. Renters who don’t use the homestead exemption at all can redirect a significant amount of that protection toward vehicles, bank accounts, or other assets where equity might otherwise be exposed.
