What Is the Accounting Equation?

The accounting equation is considered to be the foundation of the double-entry accounting system. On a companys balance sheet, it shows that a companys total assets are equal to the sum of the companys liabilities and shareholders equity.

Based on this double-entry system, the accounting equation ensures that the balance sheet remains “balanced,” and each entry made on the debit side should have a corresponding entry (or coverage) on the credit side.

Key Takeaways

  • The accounting equation is considered to be the foundation of the double-entry accounting system.
  • The accounting equation shows on a companys balance that a companys total assets are equal to the sum of the companys liabilities and shareholders equity.
  • Assets represent the valuable resources controlled by the company. The liabilities represent their obligations.
  • Both liabilities and shareholders equity represent how the assets of a company are financed.
  • Financing through debt shows as a liability, while financing through issuing equity shares appears in shareholders equity.

Accounting Equation

Understanding the Accounting Equation

The financial position of any business, large or small, is assessed based on two key components of the balance sheet: assets and liabilities. Owners’ equity, or shareholders equity, is the third section of the balance sheet. The accounting equation is a representation of how these three important components are associated with each other. The accounting equation is also called the basic accounting equation or the balance sheet equation.

While assets represent the valuable resources controlled by the company, the liabilities represent its obligations. Both liabilities and shareholders equity represent how the assets of a company are financed. If its financed through debt, itll show as a liability, and if its financed through issuing equity shares to investors, itll show in shareholders equity.

The accounting equation helps to assess whether the business transactions carried out by the company are being accurately reflected in its books and accounts. Below are examples of items listed on the balance sheet:

Assets

Assets include cash and cash equivalents or liquid assets, which may include Treasury bills and certificates of deposit. Accounts receivables are the amount of money owed to the company by its customers for the sale of its product and service. Inventory is also considered an asset.

Liabilities

Liabilities are what a company typically owes or needs to pay to keep the company running. Debt, including long-term debt, is a liability, as are rent, taxes, utilities, salaries, wages, and dividends payable.

Shareholders Equity

Shareholders equity is a companys total assets minus its total liabilities. Shareholders equity represents the amount of money that would be returned to shareholders if all of the assets were liquidated and all of the companys debt was paid off.

Retained earnings are part of shareholders equity and are equal to the sum of total earnings that were not paid to shareholders as dividends. Think of retained earnings as savings since it represents a cumulative total of profits that have been saved and put aside or retained for future use.

Accounting Equation Formula and Calculation

 Assets = ( Liabilities + Owner’s Equity ) /text{Assets}=(/text{Liabilities}+/text{Owners Equity}) Assets=(Liabilities+Owner’s Equity)

The balance sheet holds the basis of the accounting equation:

  1. Locate the companys total assets on the balance sheet for the period.
  2. Total all liabilities, which should be a separate listing on the balance sheet.
  3. Locate total shareholders equity and add the number to total liabilities.
  4. Total assets will equal the sum of liabilities and total equity.

As an example, lets say for the fiscal year, leading retailer XYZ Corporation reported the following on its balance sheet:

  • Total assets: $170 billion
  • Total liabilities: $120 billion
  • Total shareholders equity: $50 billion

If we calculate the right-hand side of the accounting equation (equity + liabilities), we arrive at ($50 billion + $120 billion) = $170 billion, which matches the value of the assets reported by the company.

The Double-Entry System

The accounting equation forms the foundation of double-entry accounting and is a concise representation of a concept that expands into the complex, expanded, and multi-item display of a balance sheet. The balance sheet is based on the double-entry accounting system where the total assets of a company are equal to the total liabilities and shareholder equity.

Essentially, the representation equates all uses of capital (assets) to all sources of capital, where debt capital leads to liabilities and equity capital leads to shareholders equity.

For a company keeping accurate accounts, every single business transaction will be represented in at least two of its accounts. For instance, if a business takes a loan from a financial entity like a bank, the borrowed money will raise the companys assets and the loan liability will also rise by an equivalent amount.

If a business buys raw material by paying cash, it will lead to an increase in the inventory (asset) while reducing cash capital (another asset). Because there are two or more accounts affected by every transaction carried out by a company, the accounting system is referred to as double-entry accounting.

The double-entry practice ensures that the accounting equation always remains balanced, meaning that the left side value of the equation will always match with the right side value. In other words, the total amount of all assets will always equal the sum of liabilities and shareholders equity.

The global adherence to the double-entry accounting system makes the account keeping and tallying processes much easier, standardized, and fool-proof to a good extent. The accounting equation ensures that all entries in the books and records are vetted, and a verifiable relationship exists between each liability (or expense) and its corresponding source; or between each item of income (or asset) and its source.

Limits of the Accounting Equation

Although the balance sheet always balances out, the accounting equation doesnt provide investors information as to how well a company is performing. Instead, investors must interpret the numbers and decide for themselves whether the company has too many or too few liabilities, not enough assets, or perhaps too many assets, or is financing the company properly to ensure long term growth.

Real World Example

Below is a portion of Exxon Mobil Corporations (XOM) balance sheet in millions as of Dec. 31, 2019:

  • Total assets were $362,597
  • Total liabilities were $163,659
  • Total equity was $198,938

The accounting equation whereby assets = liabilities + shareholders equity is calculated as follows:

  • Accounting equation = $163,659 (total liabilities) + $198,938 (equity) equals $362,597, (which equals the total assets for the period)

Frequently Asked Questions

What is the accounting equation?

The accounting equation is the proposition that a company’s assets must be equal to the sum of its liabilities and equity. Phrased differently, it means that the equity of a company is equal to its assets minus its liabilities. This concept is part of the theoretical foundation behind double-entry bookkeeping, and forms the basis for how investors and accountants interpret and analyze financial statements.

Why is the accounting equation important?

The accounting equation is important because it captures the relationship between the three components of a balance sheet: assets, liabilities, and equity. All else being equal, a company’s equity will increase when its assets increase, and vice-versa. Likewise, adding liabilities will decrease equity, whereas reducing liabilities—such as by paying off debt—will increase equity. These basic concepts are captured by the accounting equation and are essential to modern accounting methods.

What is an example of the accounting equation?

To illustrate, suppose we have a company with $1 million in assets and $500,000 in liabilities. According to the accounting equation, Assets = Liabilities + Equity. By plugging in these figures, we can quickly discern that the company’s Equity would be $500,000. These values would appear on the company’s balance sheet, and could be used by investors, analysts, or company managers to assess the quality of the business and forecast its future prospects.
