Owner’s equity is the value of a business that the owner can claim, and consists of total assets minus total liabilities. Both the amount and how much it has changed from one accounting period to another offer insights into a business’s financial condition. Sole proprietors and partnerships use this term. We’ll review what comprises this important element of a balance sheet, as well as how to calculate the metric.
You can also work with a financial advisor if you’re evaluating equity in a business you’re considering investing in.
What Is Owner’s Equity?
Owner’s equity is one of the four basic financial statements of a business. The other three are income statement, balance sheet and statement of cash flows. Sole proprietors and partnerships use the term “owner’s equity, while corporations use “shareholder’s equity.” “Book value” is another term. It’s used interchangeably with shareholder’s equity in a corporation’s balance sheet.
What Is a Statement of Owner’s Equity?
The statement of owner’s equity provides a comprehensive view of how equity changes over a specific period of time, offering more detail than the equity section of a balance sheet.
For sole proprietorships and privately held businesses, this statement outlines the starting equity balance, net income, additional investments or withdrawals made by the owner or owners, as well as non-cash contributions such as equipment. It may also include nonrecurring items, like gifts or forgiven debts. The final equity total should align with the equity figure reported on the balance sheet.
If any adjustments are needed after closing a prior period’s books – this could be due to issues such as mathematical errors, misapplied accounting principles or transitioning from cash-basis to accrual-basis accounting – these changes are reflected as “prior period adjustments” within the statement of owner’s equity.
What Are the Components of Owner’s Equity?

One component is the firm’s assets. This includes money, property, any inventory and capital goods. It also includes any additional funds the owner has added to the company since startup, either from net income or fresh capital from additional owners. Greater investment by the owner, all things being equal, means more owner’s equity.
A second element is its liabilities. This includes money taken out of the business to pay wages and salaries as well as paying down debts. Sometimes owner’s equity is called a residual claim on company assets, since liabilities have a higher claim than the owner’s claims.
It also includes retained earnings. These are profits that are reinvested in the company rather than being distributed to the owner or owners as dividends or used to pay down debt. Retained earnings can grow to become a large part of owner’s equity over time.
The Formula for Owner’s Equity
The simplest way is to subtract liabilities from assets. The formula is:
Assets – Liabilities = Owner’s Equity
Assets will include the inventory, equipment, property, equipment and capital goods owned by the business, as well as retained earnings, which may be in the form of cash in a bank account. Accounts receivable owed to the business by customers will also be included as assets. On a typical balance sheet, assets will be listed on the left side.
Liabilities will include bank loans and other debts, wages and salaries owed to employees, unpaid rent and utilities. Balance sheets generally list liabilities in a column on the right side.
Owner’s equity also shows on the right-hand sign of the balance sheet. While it’s an asset to the owner, to the business it represents a potential claim, so it’s listed on the same side as liabilities.
As an example, consider an auto repair shop with assets that include a building worth $500,000, equipment worth $250,000, inventory worth $50,000, retained earnings of $25,000 in a bank account and accounts receivable valued at $30,000. Adding all these up produces assets of $855,000.
Assets = $500,000 + $250,000 + $50,000 + $25,000 + $30,000 = $855,000
On the liability side, the building has a mortgage of $350,000, owes $100,000 to equipment vendors and suppliers, and $100,000 in unpaid wages and salaries. This comes to $550,000.
Liabilities = $350,000 + 100,000 + $100,000 = $550,000
Using the formula to subtract liabilities form assets shows that the owner’s equity in this auto repair business is $305,000.
Owner’s equity = $855,000 – $550,000 = $305,000
Factors Affecting Owner’s Equity
Owner’s equity can increase if revenues and profits increase and profits are retained, that is, reinvested in the business.
If the company loses money, on the other hand, it will be reduced. It can also be decreased by the amount of the “draw” the owner takes as compensation. However, if the owner or owners inject more money into the business, known as paid-in capital, it can offset or minimize a reduction in owner’s equity from a loss or draw.
Knowing the owner’s equity or shareholder’s equity is essential for calculating a firm’s debt-to-equity ratio. Knowing how leveraged or indebted a business is can be an indication of how how solid a company’s financial condition is. Keep in mind, though, depending on the industry and where the company is in its life cycle, a high level of debt may not necessarily be a bad thing.
Bottom Line

Owner’s equity reflects the portion of a business’s value that belongs to the owner if the business were to be liquidated. It’s determined by subtracting the total liabilities from the total assets. This metric serves as a key indicator of a business’s performance and future potential. Growth in owner’s equity from one year to the next often signals strong management and business success, while a decline may suggest the need for the owner to invest additional capital to stabilize or grow the business.
