Equity is what you actually own in an asset after subtracting what you owe on it. If your home is worth $400,000 and the mortgage balance is $250,000, your equity is $150,000. What is considered equity follows the same logic across real estate, business ownership, and stocks: the market value of the asset minus every debt secured against it or claim ahead of you. Whatever remains is yours.
The Formula Behind Every Equity Calculation
The accounting equation is straightforward: assets minus liabilities equals equity. Assets are everything of economic value you or your business owns, from cash and real estate to equipment and investments. Liabilities are every financial obligation owed to someone else, including loans, unpaid bills, and taxes due. Whatever is left after paying off every creditor is the equity, sometimes called the owner’s residual interest.
Two versions of “value” matter here. Book value is what an asset originally cost, adjusted for depreciation over time. Market value is what someone would pay for it today. These figures often diverge. A commercial building purchased for $500,000 a decade ago might now appraise at $900,000, while a piece of specialized equipment might be worth less than what the books show. For any practical purpose, market value gives you the more honest number.
Equity in a Home
Home equity is the gap between your property’s current market value and the total debt secured against it.1Freddie Mac. Understanding Your Home’s Equity You start building it the moment you make a down payment. FHA loans allow a down payment as low as 3.5% of the purchase price.2U.S. Department of Housing and Urban Development (HUD). Loans Conventional financing through Fannie Mae goes as low as 3% for qualifying borrowers.3Fannie Mae. 97% Loan to Value Options Each monthly mortgage payment chips away at the principal balance, and your equity grows by exactly that amount.
Property appreciation is the other engine. When home values in your area climb, your equity increases without any extra payment on your part. The reverse also happens. A market downturn can push you into negative equity, where you owe more than the home is worth, which locks you out of selling without bringing cash to the closing table or negotiating a short sale.
The 20% Equity Threshold
If you put down less than 20%, your lender will require Private Mortgage Insurance. PMI typically runs between 0.5% and 1.86% of the loan amount annually, or roughly $40 to $130 per month for every $100,000 borrowed.4Fannie Mae. What to Know About Private Mortgage Insurance Once your principal balance drops to 80% of the home’s original value, you can ask your servicer to cancel PMI. If you don’t ask, the servicer must automatically terminate it once the balance reaches 78%.5Consumer Financial Protection Bureau. When Can I Remove Private Mortgage Insurance (PMI) From My Loan? Crossing the 20% equity mark is one of the more tangible rewards of steady payments.
What Reduces Your Equity
Your primary mortgage is not the only claim on the house. A second mortgage, home equity loan, or HELOC creates an additional lien. Unpaid property taxes and contractor liens for renovation work can also attach. When a property is sold or foreclosed, these debts are paid in a strict priority order. The first mortgage gets paid first, then junior liens in the order they were recorded, and the homeowner receives whatever remains. A lien with low priority might collect nothing at all if the sale price doesn’t cover the debts ahead of it.
Priority generally follows a “first in time, first in right” rule, but certain claims can jump the line. Depending on the state, unpaid property taxes, special assessments, and some homeowners association liens can outrank even the first mortgage.
Equity in Stocks
When you buy shares of a publicly traded company, you’re buying a fractional ownership stake. Shareholder equity is the total value of the company’s assets minus everything it owes to creditors and bondholders. That figure appears on the corporate balance sheet and is disclosed in the annual 10-K filing with the SEC.6SEC.gov. Investor Bulletin: How to Read a 10-K
Two components make up most of shareholder equity. Paid-in capital is the money the company raised by issuing stock, whether at IPO or in later offerings. Retained earnings are the cumulative profits the company reinvested rather than paying out as dividends. A company with steadily growing retained earnings is compounding its equity over time, which tends to push its stock price upward.
Common and Preferred Shares
Common shareholders vote on corporate matters and benefit from price appreciation, but they sit last in line if the company liquidates. Preferred shareholders generally hold a higher claim on assets and receive fixed dividends before common shareholders get anything. In a bankruptcy, secured creditors are paid first, then unsecured creditors, then preferred shareholders, and finally common shareholders. In practice, common shareholders in a bankrupt company often receive nothing.
Equity as Employee Compensation
Many companies pay employees partly in equity. The two most common forms work quite differently.
Restricted stock units are a promise to give you actual shares once a vesting schedule is met, typically over three to four years. You don’t pay anything to receive them. When RSUs vest, their fair market value counts as ordinary income, taxed at your regular rate and reported on your W-2. Any future gains or losses when you sell are then taxed as capital gains.
Stock options give you the right to buy shares at a set strike price for a limited period. If the market price rises above the strike, you can exercise and pocket the difference. If it doesn’t, the options expire worthless. Non-qualified stock options are taxed as ordinary income at exercise on the spread between the strike price and market value. Incentive stock options receive preferential tax treatment, with no ordinary income tax at exercise, though they can trigger the alternative minimum tax.
Equity in a Private Business
Equity in an LLC, partnership, or sole proprietorship works differently than owning publicly traded shares. There is no stock ticker. Instead, each owner has a capital account that tracks their initial contribution, their share of profits and losses, and any withdrawals. These accounts rise when the business earns income and fall when owners take distributions.
The operating agreement for an LLC or the partnership agreement spells out each owner’s percentage stake and their rights during events like a buyout, an owner’s death, or dissolution. These documents matter because they override default state rules that might not reflect what the owners actually intended. Partnerships report income to the IRS on Form 1065, and each partner receives a Schedule K-1 showing their share of profits, losses, and capital.7Internal Revenue Service. 2025 Instructions for Form 1065 – U.S. Return of Partnership Income The K-1 also reports each partner’s beginning and ending capital account balance for the year.8Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065)
Putting a Number on a Private Stake
The trickiest part of private business equity is figuring out what it’s worth. Without a public market setting the price, owners and buyers typically rely on a multiple of the company’s annual earnings before interest, taxes, depreciation, and amortization. A business earning $500,000 in EBITDA might be valued at four to six times that amount, depending on industry, growth trajectory, and comparable transactions. The resulting enterprise value, minus outstanding debt, gives you the equity value.
This matters most during a buyout, divorce, or estate settlement, where an actual dollar figure has to be assigned to the ownership stake. Many operating agreements require a professional valuation in these situations, and the methodology chosen can swing the number by hundreds of thousands of dollars.
Net Worth Is Total Personal Equity
Net worth is the sum of all your equity across every asset class. Add up the market value of your home, investment accounts, retirement funds, business interests, vehicles, and other property. Subtract every liability: mortgages, student loans, credit card balances, car loans, and any other debts. What remains is your total equity in financial terms.
Tracking that figure over time matters more than any single snapshot. A person with $200,000 in home equity but $180,000 in student loans and credit card debt has a very different financial position than someone with the same home equity and no other debt. The number shifts constantly as markets move, balances get paid down, and property values change. Checking it annually gives you an honest reading of whether you are actually building wealth or accumulating assets alongside matching debt.
What Happens When Equity Gets Realized or Threatened
Equity on paper and equity in your pocket are two different things. Selling an appreciated asset generally triggers capital gains tax, with a preferential long-term rate for holdings kept longer than a year and ordinary income rates for anything held twelve months or less. A primary residence gets special treatment: if you owned and lived in the home for at least two of the five years before selling, you can exclude up to $250,000 of gain from federal income tax, or $500,000 for a married couple filing jointly.9Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence The exclusion does not apply to investment properties or vacation homes.
Borrowing against home equity carries its own tax rule. Interest on home equity debt is only deductible if the borrowed funds are used to buy, build, or substantially improve the home that secures the loan.10Internal Revenue Service. Publication 936 (2025), Home Mortgage Interest Deduction Using a HELOC to consolidate credit card debt or fund a vacation eliminates the deduction.
Home equity can also be shielded from creditors in bankruptcy through a homestead exemption. The federal exemption covers $31,575 per person, but most states set their own amounts, ranging from a few thousand dollars in some states to unlimited protection in Texas, Florida, Iowa, and Kansas. A few states, including New Jersey and Pennsylvania, offer no homestead exemption at all. Which set of exemptions applies depends on state law, and some states let filers choose between the federal and state options.
