The Basics – Debits And Credits

Definition: Debits and credits are equal but opposite entries in the double-entry accounting system used to record financial transactions.

How It Works: In the double-entry accounting system, every financial transaction is recorded using a debit (DR) and a credit (CR) entry. A debit entry increases asset or expense accounts and decreases liability, revenue, and equity accounts. On the other hand, credit entries are employed to decrease asset or expense accounts and increase liability, revenue, and equity accounts. 

What Are Debits And Credits?

Debits and credits are fundamental concepts in accounting that form the basis of the double-entry bookkeeping system.1 This system is used to record financial transactions accurately and maintain the integrity of a company's financial records. In this context, "debits" and "credits" do not refer to increases or decreases in value, but indicate how transactions are recorded in different accounts. A debit entry represents an increase in assets or expenses and a decrease in liabilities, equity, or revenue. Conversely, a credit entry signifies an increase in liabilities, equity, or revenue, and a decrease in assets or expenses.

Why Are Debits And Credits Important?

Debits and credits serve as the foundation of accurate financial record-keeping and reporting. By properly applying debits and credits, accountants ensure that the accounting equation (assets = liabilities + equity) remains balanced. This principle provides a clear and systematic approach to tracking financial activities, enabling accountants to generate reliable financial statements.

How Do Debits And Credits Work?

Debits and credits work in tandem within the double-entry bookkeeping system to ensure that each financial transaction is accurately recorded and balanced. For every transaction entered into the system, there must be at least one debit entry and one credit entry, and the total debits must equal the total credits.

What Are The Benefits Of Debits And Credits?

Debit and credit entries provide several benefits in the field of accounting. Let's explore some of these benefits in more detail:

Accurate Financial Reporting

Debits and credits ensure that each financial transaction is recorded accurately and consistently.

Error Detection

Since every transaction requires corresponding debits and credits that must balance, any discrepancies between the two sides of the equation can signal a mistake in the recording process. This built-in error-checking mechanism prompts accountants to review and rectify errors before they can significantly impact the integrity of financial records.

Consistent Methodology

This uniform approach allows accountants and financial professionals to communicate and understand financial data effectively across different industries and organizations.

Are There Any Downsides To Debits And Credits?

While the concept of debits and credits forms a solid foundation for accurate accounting, companies may sometimes face the following challenges when dealing with unique accounting scenarios: 

Complexity: For newcomers to accounting, grasping the concept of debits and credits can be challenging. It requires a solid understanding of accounting principles and practices. 

Human Error: As with any manual entry system, there is always the potential for human error when recording transactions. Diligence and attention to detail are crucial to minimize mistakes.

What Are The Examples Of Debits And Credits?

To illustrate the application of debits and credits, here are some common examples:

Cash Purchase Of Supplies

When a business buys supplies using cash, it results in a decrease in the cash account (credited) and an increase in the supplies account (debited).

Loan Received From Bank

In the case of receiving a loan from a bank, the business cash account is increased (debited) as the loan amount enters the company. Simultaneously, a liability account, often labeled as "Loan Payable" or a similar term, is credited. This reflects the company's obligation to repay the loan in the future.

Sales Of Goods On Credit

When a business sells goods to a customer on credit, the revenue account (sales) is credited, recognizing the increase in revenue generated by the sale. At the same time, the accounts receivable account is debited, representing the amount owed by the customer.

Payment Of Salaries 

In this scenario, the salaries expense account is debited, reducing the company's net income. At the same time, the company's cash account is credited, reflecting the decrease in cash due to the outgoing payment.

How To Record Transactions With Debits And Credits?

Recording transactions with debits and credits follows a consistent process. Here's a step-by-step guide: 

  1. Identify The Accounts: Determine the accounts impacted by the transaction. It usually involves at least two accounts. 
  2. Determine Debit Or Credit: Apply the appropriate debit or credit rule to each account based on the transaction's nature.  
  3. Amounts: Assign the monetary value to each debit and credit entry. 
  4. Entry Sequence: Record the debit entry first, followed by the credit entry. This maintains the equation's balance. 
  5. Verify The Equation: Ensure that the equation (assets = liabilities + equity) remains balanced after recording the transaction.

What Are Debits And Credits In Different Account Categories?

Debits and credits are applied differently based on the account categories involved. Here's a breakdown:


  • Increase: Debited (e.g., cash, inventory)
  • Decrease: Credited (e.g., accounts payable, sales)


  • Increase: Credited (e.g., loans, accounts payable)
  • Decrease: Debited (e.g., loan payments, reduction in payables)


  • Increase: Credited (e.g., owner's investment, retained earnings)
  • Decrease: Debited (e.g., owner's withdrawals, net loss)


  • Increase: Credited (e.g., sales, service income)
  • Decrease: Debited (e.g., sales returns, discounts)


  • Increase: Debited (e.g., salaries, utilities)
  • Decrease: Credited (e.g., expense reversals, discounts received)

What Is The Double-Entry Accounting System?

The double-entry accounting system is a fundamental principle in financial accounting that ensures accurate and balanced recording of financial transactions. It is based on the concept that every financial transaction has an equal and opposite entry made in two different accounts simultaneously. This system follows the idea that every debit must have a corresponding credit of the same amount, maintaining the accounting equation's equilibrium: assets = liabilities + equity.2

What Is The History Of Debits And Credits?

The history of debits and credits dates back to the 15th century, when Venetian merchants began using a double-entry bookkeeping system to record their financial transactions. 

However, it wasn't until 1494 that the system was formally documented by the Italian mathematician Luca Pacioli in his book Summa de Arithmetica, Geometria, Proportioni et Proportionalita.3 Pacioli's work not only revolutionized the way businesses managed their finances but also contributed significantly to the development of economic theory and financial reporting standards that continue to shape the world of finance and accounting to this day.

What Is The Current Environment Of Debits And Credits?

The current environment of debits and credits has evolved significantly since its historical origins. With the advent of modern technology and computerized accounting systems, the process of recording financial transactions has become more streamlined and efficient. 

International financial reporting standards, such as the Generally Accepted Accounting Principles (GAAP) and the International Financial Reporting Standards (IFRS), have also been established to ensure consistency and transparency in financial reporting across different countries and industries.

Frequently Asked Questions 

Are debits always positive and credits always negative?

No, debits and credits are not inherently positive or negative. Their interpretation depends on the context of the account and the accounting system being used. In some cases, debits may signify increases while credits represent decreases, and vice versa in other scenarios. 

Could I use debits and credits in personal finance?

While the concept of debits and credits originated from business accounting, individuals can apply similar principles to track personal finances accurately.

Is it possible to have a transaction with more than one debit or credit?

Yes, complex transactions often involve multiple accounts and may require more than one debit and credit entry to maintain the equation's balance.

Are debits and credits relevant in cash-based accounting?

Cash-based accounting primarily focuses on cash inflows and outflows, and the concept of debits and credits is not as prominent as in accrual-based accounting. However, understanding debits and credits is still beneficial for accurate financial reporting.

What is in the trial balance?

The trial balance comprises a list of all accounts and their respective debit or credit balances from the general ledger. 

How do debits and credits affect the calculation of net income?

Debits and credits impact the calculation of net income by reflecting changes in revenue, expenses, gains, and losses in a company's financial records. Debits are used to record increases in expenses and decreases in revenue, while credits signify increases in revenue and decreases in expenses. The net difference between total debits and total credits ultimately determines the company's net income, with a positive difference indicating profit and a negative difference indicating a loss. 

How do debits and credits affect the owner's equity account?

Debits and credits affect the owner's equity account by reflecting changes in the owner's investment or withdrawal of funds, and revenues and expenses. Owner's equity increases with credits (e.g., capital contributions, revenues) and decreases with debits (e.g., withdrawals, expenses), reflecting the owner's claim on the business's net assets.

What is the normal balance between asset and expense accounts?

Asset and expense accounts have a normal debit balance. This means that an increase in assets or expenses is recorded as a debit entry, while a decrease is recorded as a credit entry. 

Can debits and credits be used in non-financial contexts?

Yes! While debits and credits are commonly associated with financial transactions, their principles can also be metaphorically applied to non-financial contexts to represent opposite actions or effects within a system, although the terminology might differ.

Can debits and credits be used in financial forecasting?

While debits and credits are not typically used directly in financial forecasting, understanding the principles of debits and credits is valuable for developing accurate financial forecasts. Proper recording and analysis of transactions using debits and credits can provide insights and data necessary for creating reliable financial projections.
