What Is Equity?
The owner's true share of a business — what's left after every debt is paid.
Equity is one of the most important concepts in accounting and business finance. If you've ever looked at a balance sheet, you've probably seen a section called "Equity" or "Owner's Equity." But what exactly does it mean?

In simple terms:
Equity represents the owner's share of a business after all liabilities have been paid. Understanding equity helps business owners evaluate the financial health of their business and understand how much of the company they truly own. In this guide, we'll explain what equity is, how it is calculated, and why it matters.
What Is Equity?
Equity is the value that remains after subtracting a business's liabilities from its assets.
This means equity represents the owner's residual interest in the business. If all assets were sold and all debts were paid, the amount left over would belong to the owners.
A Simple Equity Example
Let's look at a simple example.
This means the owners have a claim on $60,000 of the business's value.
Equity and the Accounting Equation
Equity is one of the three components of the accounting equation.
Assets
Liabilities
Equity
This equation forms the foundation of double-entry accounting. Every transaction affects at least one part of this equation. For example, investing money increases equity, earning profits increases equity, taking on debt increases liabilities, and owner withdrawals reduce equity.
Where Does Equity Appear?
Equity appears on the balance sheet. A simplified balance sheet may look like this:
The balance sheet remains balanced because Assets = Liabilities + Equity.
What Increases and Decreases Equity?
Here's the breakdown:
📈 Increases Equity
- Owner contributions — e.g. an owner invests $10,000 cash, equity rises by $10,000.
- Business profits — e.g. a $5,000 profit increases equity by $5,000 through retained earnings.
📉 Decreases Equity
- Business losses — reduce retained earnings and therefore equity.
- Owner withdrawals — e.g. an owner withdraws $2,000, cash and equity both decrease.
This is one reason profitable businesses generally build equity over time.
Types of Equity
The exact names vary depending on the business structure.
🧍 Sole Proprietorship
- Owner's Equity
- Capital Account
🤝 Partnership
- Partner Capital Accounts
🏢 Corporation
- Share Capital
- Retained Earnings
- Additional Paid-In Capital
Regardless of the terminology, the underlying concept remains the same.
What Is Retained Earnings?
Retained earnings are profits that remain in the business after distributions to owners. Over time, retained earnings become a significant component of equity.
These retained profits contribute to overall equity.
A strong equity balance can indicate:
- Long-term financial stability
- Profitability over time
- Reduced reliance on debt
- Greater business value
Lenders and investors often review equity when assessing a business.
Can Equity Be Negative?
Yes.
Negative equity occurs when liabilities exceed assets. For example: Assets of $50,000 minus Liabilities of $70,000 equals Equity of -$20,000. This may indicate financial difficulties and should be investigated carefully.
Equity vs Profit
Many beginners confuse equity and profit. They are related but different.
Profit
- Measures performance over a period.
- Appears on the income statement.
Equity
- Measures ownership value at a point in time.
- Appears on the balance sheet.
Profits can increase equity, but they are not the same thing. To see how profit itself breaks down, read Gross Profit vs Net Profit: What's the Difference?
Think of Selling Your House
If you sold your house for $300,000 but still owed $200,000 on the mortgage, your equity would be $100,000 — what's actually yours. A business works exactly the same way: sell everything, pay every debt, and whatever's left is equity.
Conclusion
Equity is the clearest measure of what a business is actually worth to its owners. By tracking Assets minus Liabilities, you can see whether your ownership stake is growing or shrinking — and whether the business is building real, lasting value over time.
