Discover how the general ledger records financial transactions, how account balances are calculated, and how the ledger supports accurate financial reporting.
What Is a General Ledger?
The general ledger is the main accounting record containing transactions posted to a business’s individual accounts.
Each account records debit and credit movements and provides information used to calculate the account balance.
General ledger accounts include assets, liabilities, equity, income and expenses.
Why Is the General Ledger Important?
- Organises transactions by account
- Shows account movements and balances
- Supports preparation of the trial balance
- Provides information for financial statements
- Helps investigate posting errors
- Supports reconciliations and audit trails
How Does the General Ledger Work?
Under double-entry bookkeeping, each transaction has equal total debits and credits.
Those amounts are posted to the relevant general ledger accounts.
The debit and credit entries accumulated in each account are used to determine its balance.
Practical General Ledger Example
Imagine a new sole trader business completing these four transactions:
- The owner invests £2,000 into the business bank account.
- The business receives £800 cash from providing services.
- The business pays £300 for office rent.
- The business purchases office equipment for £500.
All transactions are paid through the bank. Ignore VAT and assume the equipment is capitalised.
Step 1: Record the Journal Entries
| Transaction | Debit | Credit |
|---|---|---|
| Owner invests £2,000 | Bank £2,000 | Owner’s Capital £2,000 |
| Services sold for £800 | Bank £800 | Service Revenue £800 |
| Rent paid £300 | Rent Expense £300 | Bank £300 |
| Equipment purchased £500 | Office Equipment £500 | Bank £500 |
Step 2: Post Transactions to Ledger Accounts
Let’s examine the individual accounts.
Bank Account
| Description | Debit (£) | Credit (£) |
|---|---|---|
| Owner’s capital | 2,000 | – |
| Service revenue | 800 | – |
| Rent payment | – | 300 |
| Equipment purchase | – | 500 |
| Total movements | 2,800 | 800 |
Other General Ledger Balances
| Account | Debit Balance (£) | Credit Balance (£) |
|---|---|---|
| Bank | 2,000 | – |
| Office Equipment | 500 | – |
| Rent Expense | 300 | – |
| Owner’s Capital | – | 2,000 |
| Service Revenue | – | 800 |
| Total | 2,800 | 2,800 |
These closing balances can be used to prepare a trial balance.

General Ledger vs Trial Balance
The general ledger contains the detailed entries recorded in each account.
A trial balance summarises the closing debit or credit balance of each general ledger account at a particular date.
The trial balance helps check whether total debit balances equal total credit balances.

Test Your Knowledge
A bank ledger account has total debit movements of £5,000 and total credit movements of £3,200. Assume it has no opening balance.
What is the closing bank balance?

£5,000 − £3,200 = £1,800 debit balance.
The debit balance represents the positive bank asset balance in this example.
