Definition of Chart of Accounts
A Chart of Accounts (COA) is an organized list of all accounts used by a business to record financial transactions systematically. It acts like an index of a company’s financial books, categorizing transactions into assets, liabilities, equity, income, and expenses for accurate bookkeeping and reporting.
Meaning of Chart of Accounts in Detail
The Chart of Accounts is essentially the backbone of an organization’s accounting system. Every financial entry, from sales revenue to office expenses, is classified under a unique account number and name.
Think of it as a financial dictionary for a business:
-
It tells you where to record each transaction.
-
It ensures consistency across reporting periods.
-
It simplifies preparing financial statements like the Balance Sheet and Profit & Loss Account.
Without a well-structured COA, financial data would be scattered and unreliable, making decision-making difficult for managers, investors, and auditors.
Structure of a Chart of Accounts
A COA is typically divided into major categories:
-
Assets: Cash, accounts receivable, equipment.
-
Liabilities: Accounts payable, loans.
-
Equity: Share capital, retained earnings.
-
Revenue/Income: Sales, service income, interest income.
-
Expenses: Salaries, rent, utilities, depreciation.
Each category is further divided into sub-accounts with a coding system, for example:
| Account Code | Account Name | Category |
|---|---|---|
| 1000 | Cash | Asset |
| 2000 | Accounts Payable | Liability |
| 3000 | Share Capital | Equity |
| 4000 | Sales Revenue | Income |
| 5000 | Office Supplies Expense | Expense |
Formula / Calculation
While a Chart of Accounts is not a formula-based concept, it is built upon the accounting equation:
Assets = Liabilities + Equity
This equation forms the foundation of all accounts in the COA.
Example Calculation
Suppose a business purchases office supplies worth ₹5,000 in cash.
-
Expense increases (Office Supplies ₹5,000).
-
Asset decreases (Cash ₹5,000).
This entry is classified under the Expense and Asset accounts in the COA.
Journal Entry Example
Transaction: Office Supplies purchased for ₹5,000 in cash.
Journal Entry:
| Date | Particulars | Debit (₹) | Credit (₹) |
|---|---|---|---|
| 01-04-2025 | Office Supplies Expense | 5,000 | |
| Cash | 5,000 |
This follows the COA coding:
-
Office Supplies Expense → Account Code 5000
-
Cash → Account Code 1000
Detailed Illustration
Imagine a business has the following transactions:
-
Owner invests ₹1,00,000 in business.
-
Purchases furniture worth ₹20,000.
-
Earns service revenue of ₹15,000.
-
Pays salary of ₹5,000.
Journal Entries (with COA classification):
| Date | Particulars | Debit (₹) | Credit (₹) | Account Code |
|---|---|---|---|---|
| 01-04-2025 | Cash | 1,00,000 | 1000 (Asset) | |
| Capital | 1,00,000 | 3000 (Equity) | ||
| 02-04-2025 | Furniture | 20,000 | 1500 (Asset) | |
| Cash | 20,000 | 1000 (Asset) | ||
| 05-04-2025 | Cash | 15,000 | 1000 (Asset) | |
| Service Revenue | 15,000 | 4000 (Income) | ||
| 10-04-2025 | Salary Expense | 5,000 | 5000 (Expense) | |
| Cash | 5,000 | 1000 (Asset) |
