Accounting Equation is based on the double-entry bookkeeping system, which means that all assets should be equal to all liabilities in the book of accounts. All the entries made to the debit side of a balance sheet should have a corresponding credit entry on the balance sheet. Thus it is also known as the balance sheet equationBalance Sheet EquationBalance Sheet Formula is a fundamental accounting equation which mentions that, for a business, the sum of its owner’s equity & the total liabilities equal to its total assets, i.e., Assets = Equity + Liabilitiesread more.

Key Takeaways

  • The accounting equation is a fundamental accounting principle that states that the total assets of a business are equal to the sum of its liabilities and owner’s equity. It forms the basis of the double-entry accounting system.
  • The accounting equation is based on the double-entry bookkeeping system, which means that for every transaction recorded in the accounting system, the total debits must equal the total credits.
  • The accounting equation is also known as the balance sheet equation. All entries to the balance sheet debit side must have a corresponding credit entry on the balance sheet, ensuring the equation remains balanced.

Accounting Equation Explained

The concept of accounting equation show us the main principle of accounting and represents the relation between assets, liabilities and equity. According to the equation, the assets of the business are equal to the equity and liabilities.  

The assets of a business show the resources that the company has in the form of property, machinery and equipments, inventory, cash, etc. the liabilities are the obligations of the business or the funds that it owes to outsiders like creditors, investors, etc, in the form of loan, accounts payable or taxes.

The equity consists of the contribution of the owner and the retained earnings. The accounting equation format is the main foundation of the double entry system followed in accounting process. According to the system, every transaction has two effects, a debit and a credit that are equal and opposite in nature.

If we take the example of loans taken by the company, the asset side will increase by the amount of loan, but the liability side will also increase since the loan is a liability for the business which it has to pay back to the lenders.

Video Explanation of Accounting Equation



The equation is an important concept used to assess the financial condition of the company. The formula for calculation is given below.

Assets = Liabilities + Shareholders Equity

The above accounting equation format provides the management and the stakeholders a clear snapshot of the asset, liability and equity position at a particular point of time.

How To Calculate?

Let us understand the different components of the equation in detail which will facilitate in understanding the calculation done by companies.

Hence, the total assetsTotal AssetsTotal Assets is the sum of a company's current and noncurrent assets. Total assets also equals to the sum of total liabilities and total shareholder funds. Total Assets = Liabilities + Shareholder Equityread more should always be equal to the total liabilities in a balance sheet, which fundamentally forms the basis of the whole accounting system of any company when it follows the double-entry bookkeeping system. Thus from the above details we can understand how to do accounting equation.


The equations has certain rules that every company should follow. They give us guidelines regarding how to do accounting equation.

  • It is understood that the double-entry book-entry accounting system is followed globally and adheres to the rules of debit and credit entries. These entries should tally to each other at the end of a particular period, and if there is a gap in total balances, it needs to be investigated.
  • This system makes accounting a lot easier by creating a relationship between the expense/liability and cause of expense/liability (or income/asset and source of income/asset). We need to understand the underlying concept and thumb rule of accounting, which relates to debit and credit entries at the root level.  
  • Another rule is that the total amount written on the debit of the transaction should be equal to the amount in the credit side. This will ensure that the equation balances.
  • Any increase in the assets and expenses will be debited and increase in liability, revenue and equity will be credited.
  • Similarly, any fall in assets and expenses are credited and fall in liabilities, revenue and equity are debited.
  • Although the accounting equation formula seems like a one-liner, it contains a lot of meaning and can be explored deeper with complex expense entries.

The accountants should ensure that the concept of accounting equation and its rules are properly followed and the transactions are daily and accurately recorded.


Let us understand the concept with the help of an example.

Example #1

On December 1, 2007, Kartik started his business, FastTrack Movers and Packers. The first transaction that Kartik will record for his company is his investment of $20,000 in exchange for 5,000 shares of FastTrack Movers & Packers common stock. There are no revenues because the company earned no delivery fees on December 1, and there were no expenses. How will this transaction get recorded in the balance sheet?

Example #2

A double-entry bookkeeping system helps us understand the flow of any particular transaction from the source to the end. Let’s take another basic, expanded accounting equationExpanded Accounting EquationExpanded Accounting Equation refers to the expanded version of the basic accounting equation for a specific corporation or sole proprietor, providing information on the corporation's financial transactions such as assets, liabilities, share capital, income, expenses, and more example.

When there is a purchase of an asset in a company, the purchase amount should also be withdrawn from some account in the company (generally a Cash account). Hence, the account from which the amount is withdrawn gets credited, and there needs to be an account debited for the asset purchased (the account related to the asset purchased gets debited).

Consider the below entries:

  • On December 27, Joe started a new company by investing $15,000 as equity.
  • On January 3, Joe purchased an office table for his company, which cost him $5,000.
  • He paid wages for his labor on January 5, totaling $15,000.
  • On January 10, he received a contract from his clients, and they paid him $2,000.
  • On January 13, Joe received another contract for which the client paid $4,000 in advance.
  • On January 15, he completed the service contract received on January 13, and the client paid the remaining amount of $8,000.

The Journal entries for the above transactions are as below:

DateAccount DescriptionDebitCredit
Shareholders Equity$15,000
3-JanOffice Table$5,000
5-JanWages Expense$15,000
Service Revenue$2,000
Accounts Receivables$8,000
Service Revenue$12,000
Account Receivables$8,000

The corresponding entries in a balance sheet as of January 15 should be as below:

Cash$9,000Service Revenue$14,000
Furniture A/C$5,000

It is seen that the total credit amount equals the total debt amount. It is fundamental to the double-entry bookkeeping system of accounting, which helps us understand from the illustration above that total assets should be equal to total liabilities.

In this illustration, Assets are – Cash, Furniture A/C, and Accounts ReceivableAccounts ReceivableAccounts receivables is the money owed to a business by clients for which the business has given services or delivered a product but has not yet collected payment. They are categorized as current assets on the balance sheet as the payments expected within a year. read more; Liabilities are Wage expenses and Service Revenue.

If we refer to any balance sheet, we can realize that the assets and liabilities and the shareholder’s equity are represented as of a particular date and time. Hence, as of January 15, only three accounts exist with a balance – Cash, Furniture A/C, and Service Revenue (the rest get net off during the period of the whole transaction by January 15). Only those accounts that exist with a balance (positive or negative) on a particular date are reflected on the balance sheet.

Alternatively, we can also understand that total liabilities can be derived if the only asset value is mentioned. The owner’s equity can also be determined if total assets and total liabilities are available. The basic accounting equation formula can also be used as below:

Total Liabilities = Total Assets – Shareholders Equity

Shareholders Equity = Total Assets – Total Liabilities

Hence, this forms the basis of many analyses for market investors, financial analysts, research analystsResearch AnalystsResearch analyst is a profession where the main task includes research on specific fields, analyzing the facts and figures, interpreting the analysis, and finally presenting the same to a structured audience that can relate to marketing, finance, more, and other financial institutions.

Accounting Equation In Income Statement

Not only does the balance sheet reflect the basic accounting equation as implemented, but also the income statementIncome StatementThe income statement is one of the company's financial reports that summarizes all of the company's revenues and expenses over time in order to determine the company's profit or loss and measure its business activity over time based on user more.

  • An income statement is prepared to reflect the company’s total expenses and total income to calculate the net income for different purposes. This statement is also prepared in the same conjunction as the balance sheet. However, a little differently applied.
  • Here, we do not have total assets and liabilities. Still, the statement is prepared so that if an expense is credited, it will have an equal and opposite entry in debt in a related ledger account.
  • The income statement includes the accounts which directly refer to a company’s income or expenses like Cost of Goods Sold, Tax expenses, and Interest Payable expenses.


There are some problems that company may face with implementing the accounting equation approach. They are given below:

  • Asset valuation- The accuracy of the equation can be affected by the valuation of assets. It is often very difficult to accurately value them and different companies use different methods for this purpose.
  • Accrual accounting – the equation assumes that every transaction is recorded based on accrual method of accounting. It means the expenses and revenue is recorded as and when they are earned, not when cash actually changes hands. This can create discrepancies between cash and accrual accounting, affecting the equation.
  • Transaction timing – The accounting equation approach assumes that all transactions are recorded as and when they occur.  But accountants may not always be able to record them on exact date of time, thus giving rise to timing problems or gaps.
  • Non -monetary transactions- There are transactions that are non monetary in nature like some cases of services. They are difficult to value and may not reflect correctly in the equation.

Thus, these problems should be noted by all companies and strict method of valuation and recording of transactions should be done to control such problems.
