What is a Chart of Accounts?

A chart of accounts is the organized list of every account a company uses to record financial transactions, each tagged with a unique number and category. It's the backbone that makes a company's ledger, financial statements, and reporting consistent.

Short answer

A chart of accounts is a structured, numbered list of all accounts — assets, liabilities, equity, revenue, and expenses — that a business uses to categorize every transaction it records.

Balance Sheet vs. Income Statement Accounts
Balance Sheet Accounts
  • Assets (1000s)
  • Liabilities (2000s)
  • Equity (3000s)
Income Statement Accounts
  • Revenue (4000s)
  • Expenses (5000s)

Step-by-step worked examples

A small business is setting up its chart of accounts using the standard 5-category numbering scheme (1000s Assets, 2000s Liabilities, 3000s Equity, 4000s Revenue, 5000s Expenses). Assign numbers to: Cash, Accounts Payable, Owner's Equity, Sales Revenue, Rent Expense.

Cash → 1000s (Asset), e.g. 1010
Accounts Payable → 2000s (Liability), e.g. 2010
Owner's Equity → 3000s (Equity), e.g. 3010
Sales Revenue → 4000s (Revenue), e.g. 4010
Rent Expense → 5000s (Expense), e.g. 5010

A bookkeeper needs to record a $3,000 equipment purchase on credit. Which two chart-of-accounts categories are affected?

Equipment increases → Asset account (1000s), e.g. 1500 Equipment
Amount owed increases → Liability account (2000s), e.g. 2020 Accounts Payable
Entry: Debit Equipment $3,000; Credit Accounts Payable $3,000

A growing company wants to add sub-accounts for 'Office Supplies Expense' and 'Software Expense' under a general 'Operating Expenses' category. How should the numbering work?

Operating Expenses parent range: 5000–5099
Office Supplies Expense → 5010
Software Expense → 5020
Leaving gaps (5011–5019, 5021–5029) allows future sub-accounts without renumbering
