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.
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.
- •Assets (1000s)
- •Liabilities (2000s)
- •Equity (3000s)
- •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
