Cheat Sheet: 3.1 The Trial Balance
O Level and IGCSE Accounting – Quick Revision
What Is a Trial Balance?
- A trial balance is a statement of all the ledger account balances extracted on a specific date.
- It is used to check the arithmetic accuracy of the double entry system.
Format of a Trial Balance
| Account Name | Debit ($) | Credit ($) |
|---|---|---|
| Cash | 1,200 | |
| Capital | 10,000 | |
| Inventory | 2,000 | |
| Sales | 15,000 | |
| Purchases | 9,000 | |
| Rent Expense | 500 | |
| Trade Receivables | 3,000 | |
| Trade Payables | 2,000 | |
| Total | 15,700 | 27,000 |
✅ The totals must always balance (Debit = Credit).
If they don’t, it indicates an error in the double-entry system.
Uses of a Trial Balance
| Use | Explanation |
|---|---|
| Checks arithmetical accuracy | Ensures that debits and credits are equal |
| Basis for preparing final accounts | Used to prepare income statements and financial position |
| Helps detect certain errors | Quickly shows unbalanced entries |
Limitations of a Trial Balance
A trial balance may balance even if there are errors in the accounting records. These are known as errors not revealed.
Errors That Do NOT Affect the Trial Balance
| Type of Error | Description | Example |
|---|---|---|
| Error of Omission | Transaction is completely missed out | Purchase of goods for $500 not recorded at all |
| Error of Commission | Correct amount, correct side, wrong account of same class | Receipt from Ali (debtor) wrongly credited to Ahmed |
| Error of Principle | Entry in the wrong type of account | Motor vehicle expense debited to Motor Vehicles (asset) |
| Error of Original Entry | Wrong figure used on both sides | $450 recorded instead of $540 for same transaction |
| Error of Reversal | Correct accounts, but debit and credit reversed | Paid supplier debited to Payables and credited to Cash |
| Compensating Error | Two or more independent errors cancel each other out | Overstated rent by $200 and understated sales by $200 |
These do not affect the agreement of the trial balance, so they go undetected unless carefully reviewed.
Correcting a Trial Balance That Does Not Balance
- Check all arithmetic in ledger and journal
- Compare ledger balances against the trial balance entries
- Look for unbalanced or unposted entries
- Use a suspense account if the difference can’t be immediately found
Example: Prepare a Trial Balance
Given:
| Account | Balance ($) | Dr/Cr |
|---|---|---|
| Capital | 10,000 | Cr |
| Cash | 2,000 | Dr |
| Sales | 5,000 | Cr |
| Purchases | 3,000 | Dr |
| Rent | 500 | Dr |
Trial Balance:
| Account Name | Debit ($) | Credit ($) |
|---|---|---|
| Cash | 2,000 | |
| Purchases | 3,000 | |
| Rent Expense | 500 | |
| Sales | 5,000 | |
| Capital | 10,000 | |
| Total | 5,500 | 15,000 |
→ The trial balance does not balance → Missing $9,500 → use suspense account
