Double-entry accounting, a fundamental accounting concept that has been used for centuries, is a systematic method of recording financial transactions that ensures accuracy and accountability. “Double entry” comes from the fact that every transaction involves at least two accounts, with debits and credits entered to maintain a balance. This approach follows the accounting equation where every transaction must maintain the equality:
Assets = Liabilities + Owner’s Equity
From a more practical standpoint, a double-entry accounting or bookkeeping system keeps track of assets, liabilities, and owner’s equity as well as net income. A single-entry system only keeps track of net income.
Double-entry accounting is a foundational practice, which allows for the tracking of both net income and balance sheet. It also fosters transparency, aids in error detection, and forms the basis for key financial statements like the income statement.
Double-entry Accounting Overview
- Double-entry system: Double-entry accounting is a system where every financial transaction affects at least two accounts. For every debit entry made to one account, there must be an equal and corresponding credit entry to another account.
- Accounting equation: The foundation of double-entry accounting is the accounting equation: Assets = Liabilities + Equity. Every transaction impacts this equation with offsetting debits and credits, ensuring that it remains balanced.
- Debits and credits: Debits and credits are the two sides of a transaction. Debits are recorded on the left side of the account, and credits are recorded on the right side. Assets and expenses increase with debits, while liabilities, equity, and revenues increase with credits.
- Accounting cycle: The accounting cycle involves a series of steps, including identifying transactions, creating journal entries, posting to the ledger, preparing a trial balance, adjusting entries, preparing financial statements, and closing entries.
- Accuracy and error detection: Double-entry accounting provides a built-in system for error detection. If the accounting equation doesn’t balance, there is an error in the recording of transactions.
- Compliance and auditing: Double-entry accounting is widely accepted and used for financial reporting, allowing for accurate comparison of financial statements over time.
Double-entry Account Types
There are five main account types that are used in double-entry accounting:
- Asset accounts: The monetary value of what a business owns, such as cash, inventory, and equipment.
- Liability accounts: The debts of a business, such as accounts payable, loans, and a mortgage.
- Equity: The difference between assets and liabilities, or the funds invested in a business and the amount of profit remaining after operating costs; also known as retained income.
- Income accounts: The revenue of a business, such as sales and interest income.
- Expense accounts: The costs of a business, such as rent, utilities, payroll, and advertising.
Financial Statements Provided by Double-entry Accounting
Double-entry accounting provides the basis for the preparation of several key financial statements, which are essential for understanding and analyzing a company’s financial performance. It ensures that each transaction is recorded with offsetting debits and credits, which—when aggregated—form the basis for accurate financial reporting.
The financial statements provide valuable information for stakeholders—including investors, creditors, management, and analysts—to assess the financial health and performance of a business.
The primary financial statements resulting from double-entry accounting include:
- Balance sheet: Also known as the statement of financial position, this report provides a snapshot of a company’s financial position at a specific point in time. It presents the assets, liabilities, and equity of the business.
- Income statement: Also called the profit and loss (P&L) statement, this report shows the revenue, expenses, and net income or net loss over a specific period, such as a month, quarter, or year.
- Statement of cash flows: This statement reports the cash generated and used by a business during a specific period. It categorizes cash flows into operating, investing, and financing activities, and provides insights into how a company generates and utilizes cash.
- Statement of changes in equity: This statement outlines the changes in equity accounts over a specific period. It typically includes details about common stock, retained earnings, and other components of equity. Changes in equity arise from net income or loss, dividends, stock issuances, and other transactions that affect equity.
These financial statements are interconnected, and information from one statement often impacts another. For example, the net income reported on the income statement affects the equity section on the balance sheet and the statement of changes in equity.

Pros & Cons of Double-entry vs Single-entry Accounting
For comparison, a single-entry accounting system merely tracks items of income and expense without any regard to what bank account income was deposited or how expenses were paid. For instance, a single-entry accounting system doesn’t keep track of the balance in a business’ checking account. A double-entry accounting system tracks the checking account, which guarantees all activity in the account is recorded.
