What is owner’s equity?

Owner’s equity is the value left in your business after you subtract everything it owes (liabilities) from everything it owns (assets). It’s your business’s book value, or net worth, and shows how much of the business belongs to you. You can calculate it at any time using figures from your balance sheet.

Owner’s equity = Total assets – Total liabilities

Owner’s equity doesn’t tell you what your business would sell for. That depends on negotiations with a buyer. But it gives you a clear picture of your financial position right now.

Why owner’s equity matters

Owner’s equity shows the financial health of your business at a glance. Tracking it helps you make confident decisions about growth, funding and your business’s future.

Here’s why it matters for your business:

• Measures financial health: Positive equity means your assets exceed your debts. Negative equity signals financial stress.
• Supports loan applications: Lenders review your equity to assess whether your business can handle more debt.
• Guides valuation: Equity gives you a starting point to value your business when selling or bringing in partners.
• Tracks growth over time: Rising equity shows your business is building wealth. Declining equity may signal problems to address.
• Informs strategic decisions: Knowing your equity helps you decide when to expand, invest or pull back.

How to calculate owner’s equity

To calculate it, use the formula above. Add up everything your business owns (assets), then subtract everything it owes (liabilities), and what remains is your equity.

Understanding assets and liabilities

Count your assets and liabilities correctly to get an accurate equity figure. Assets include everything your business owns, such as:

• equipment and machinery
• real estate and property
• inventory and stock
• accounts receivable (money customers owe you)
• cash in the bank
• intangible items like intellectual property or brand value

Liabilities include everything your business owes, such as:

• loans from lenders
• amounts owed to suppliers
• wages owed to employees
• taxes owed to the South African Revenue Service (SARS)

Examples of owner’s equity

These two examples show the formula in action. The first uses a familiar personal asset, and the second applies the same steps to a business.

Personal example: house equity

Say you own a house worth R300,000 (your asset) and still owe R120,000 on the mortgage (your liability). Subtract one from the other to find your equity: R300,000 – R120,000 = R180,000.

Business example: repair shop

A repair shop owns a garage worth R600,000, machinery worth R50,000 and inventory worth R50,000, giving total assets of R700,000. Its only liability is a R300,000 loan on the premises, so the owner’s equity is R700,000 – R300,000 = R400,000.

Owner’s equity vs shareholders’ equity in a South African (Pty) Ltd

Your business structure decides who the equity belongs to and how it’s labelled on your balance sheet. Here’s how it works for a sole proprietor and a proprietary limited company (Pty Ltd).

Owner’s equity for a sole proprietor

If you trade as a sole proprietor, the equity in your business belongs entirely to you. Say your business has assets of R400,000 and liabilities of R150,000: your owner’s equity is R400,000 – R150,000 = R250,000.

That R250,000 is made up of the capital you’ve put into the business, plus profits, minus any drawings you’ve taken out.

Shareholders’ equity for a Pty Ltd

When you register a Pty Ltd, the company becomes a separate legal entity, and its equity belongs to the shareholders. The balance sheet shows this equity as share capital plus retained earnings.

Say your company has assets of R2,000,000 and liabilities of R1,200,000. Shareholders’ equity is R2,000,000 – R1,200,000 = R800,000, made up of R100,000 share capital and R700,000 retained earnings.

Because the company is separate from you, you take value out as a salary or dividends rather than drawings. The formula stays the same in both structures: total assets minus total liabilities.

Where to find owner’s equity

You’ll find it in two places on your financial statements:

• Balance sheet: Owner’s equity appears as its own section, listed after assets and liabilities.
• Statement of changes in equity: This report tracks how your equity changes over time.

What is a statement of changes in equity?

A statement of changes in equity shows how your business’s net worth changed over a period. Under International Financial Reporting Standards (IFRS), this statement compares the recorded value of equity at the start and end of a period. It shows changes from profits, owner investments and dividends.

It connects your profit and loss statement to your balance sheet by tracking how earnings affect your equity. This statement is one of the four basic financial statements:

• profit and loss statement
• balance sheet
• cash flow statement
• statement of changes in equity

The following examples show how the statement of changes in equity works for different business structures.

Statement of changes in equity for a sole proprietor

For a sole proprietor, the statement starts with opening equity, adds net profit for the year and subtracts any drawings to arrive at closing equity.

Statement of changes in equity for a partnership

In a partnership, the statement includes the same elements as for a sole proprietor, plus any extra money partners introduce, to arrive at closing equity.

Statement of changes in equity for a company

For a company, the statement tracks similar changes but includes money from investors rather than partner contributions to arrive at closing equity.

How to use your statement of changes in equity

Most small business owners focus on the profit and loss statement and balance sheet for day-to-day decisions. These reports contain the details you need to manage performance. The IFRS for SMEs standard lets some businesses present a single statement of income and retained earnings instead of a separate statement of changes in equity.

The statement of changes in equity is useful for tracking how your business value has grown over time. Use it when preparing for a sale, bringing in partners or reviewing your annual progress.

FAQs on owner’s equity

Here are answers to some common questions about owner’s equity.

Is shareholders’ equity the same as owner’s equity?

Yes, both describe the value left after you subtract liabilities from assets. Sole proprietors and partnerships typically use “owner’s equity”, while companies call it “shareholders’ equity”.

Is owner’s equity an asset or a liability?

It’s neither an asset nor a liability. Equity is the owner’s residual claim on the business’s assets once liabilities are accounted for, so it sits in its own section of the balance sheet.

How do I calculate the owner’s equity statement?

Start with your opening equity, add profits and contributions, then subtract withdrawals and losses to arrive at your closing equity. You’ll need accurate balance sheet data from the start and end of your chosen period.

Do all transactions affect owner’s equity?

Many do: earning revenue and receiving owner contributions increase equity, while paying business expenses and taking owner withdrawals decrease it. Borrowing money or paying off a loan changes your assets and liabilities by the same amount, so your equity stays the same.

Can owner’s equity be negative?

Yes, equity is negative when your business’s liabilities exceed its assets, which can happen when losses build up over time. It’s a warning sign that may require reducing expenses, increasing revenue or restructuring debt.

How often should I check my owner’s equity?

Review your equity at least quarterly when you run financial reports, or monthly if you’re actively managing growth, seeking funding or monitoring cash flow closely. Xero gives you up-to-the-minute financial data, so you can check your balance sheet whenever you need to.
