The accounting equation is the basic rule of accounting that says a company’s assets must always equal its liabilities plus equity :

Assets=Liabilities+Equity\text{Assets}=\text{Liabilities}+\text{Equity}Assets=Liabilities+Equity

What the accounting equation means

  • Assets : What the business owns or controls (cash, inventory, equipment, buildings, receivables).
  • Liabilities : What the business owes to others (loans, accounts payable, taxes payable).
  • Equity : The owner’s or shareholders’ residual interest in the business after liabilities are paid (owner’s capital, retained earnings, shareholders’ equity).

The idea: everything the business owns (assets) is funded either by outsiders (liabilities) or by owners (equity).

Why it matters (Quick Scoop)

  • It is the foundation of double-entry bookkeeping : every transaction affects at least two accounts and keeps the equation in balance.
  • It is the backbone of the balance sheet , which is sometimes called the “balance sheet equation.”
  • If the equation does not balance, it usually means there is an error in recording transactions.

Alternative forms of the equation

You can rearrange the accounting equation:

  • Equity=Assets−Liabilities\text{Equity}=\text{Assets}-\text{Liabilities}Equity=Assets−Liabilities
  • Liabilities=Assets−Equity\text{Liabilities}=\text{Assets}-\text{Equity}Liabilities=Assets−Equity

These are just algebraic variations, but they describe the same relationship between assets, liabilities, and equity.

Simple example (story-style)

Imagine you start a small design studio:

  1. You invest 10,000 in cash of your own money into the business.
    • Assets (Cash) = 10,000
    • Equity (Owner’s Capital) = 10,000
    • Equation: 10,000 (Assets) = 0 (Liabilities) + 10,000 (Equity) ✔
  2. Later, the studio takes a bank loan of 5,000.
    • Assets increase: Cash +5,000 → 15,000 total
    • Liabilities increase: Bank Loan +5,000
    • Equation: 15,000 (Assets) = 5,000 (Liabilities) + 10,000 (Equity) ✔

In both steps, the accounting equation stays perfectly balanced.

Quick HTML table view

Below is a small HTML table that shows the structure of the accounting equation:

  <thead>
    <tr>
      <th>Component</th>
      <th>What it represents</th>
      <th>Examples</th>

  <tbody>
    <tr>
      <td>Assets</td>
      <td>Resources owned or controlled by the business</td>
      <td>Cash, inventory, equipment, buildings, receivables</td>
    </tr>
    <tr>
      <td>Liabilities</td>
      <td>Obligations owed to outsiders</td>
      <td>Bank loans, accounts payable, taxes payable</td>
    </tr>
    <tr>
      <td>Equity</td>
      <td>Owners’ residual interest after liabilities</td>
      <td>Owner’s capital, retained earnings, shareholders’ equity</td>
    </tr>
  </tbody>

(Concepts in the table follow the standard accounting equation definition used in financial accounting.)

TL;DR

  • Core formula: Assets = Liabilities + Equity.
  • It keeps the books balanced in double-entry accounting and underlies the balance sheet.
