- Understand the purpose and limitations of a Trial Balance
- Identify common errors
Concept Framework
What is a Trial Balance?
A Trial Balance is a statement prepared at a particular date listing all ledger account balances.
It ensures that total debits equal total credits.
Purpose of a Trial Balance
It:
• Tests arithmetic accuracy
• Assists in preparing financial statements
• Detects certain types of errors
Format of a Trial Balance
Two columns:
Debit (£)
Credit (£)
Each ledger balance is entered on the appropriate side.
Limitations of a Trial Balance
Even if totals agree, errors may still exist, such as:
• Errors of omission
• Errors of principle
• Compensating errors
Therefore, agreement does not guarantee complete accuracy.
Worked Examples
Example 1
Ledger Balances:
Cash £12,000 (Debit)
Capital £50,000 (Credit)
Purchases £18,000 (Debit)
Sales £30,000 (Credit)
Rent £5,000 (Debit)
Trial Balance:
| Account | Debit (£) | Credit (£) |
|---|---|---|
| Cash | 12,000 | |
| Purchases | 18,000 | |
| Rent | 5,000 | |
| Capital | 50,000 | |
| Sales | 30,000 |
Totals must agree.

Structured Practice
Level 1 – Concept Check
Define Trial Balance.
State two purposes of a Trial Balance.
State one limitation.
Level 2 – Application Practice
Prepare a Trial Balance from the following balances:
Cash £8,000 (Dr)
Capital £20,000 (Cr)
Sales £15,000 (Cr)
Purchases £10,000 (Dr)
Wages £2,000 (Dr)
Level 3 – Examination Style Questions
Explain why a Trial Balance that balances does not necessarily mean the accounts are free from error. (6 marks)
📌 Additional structured Trial Balance questions are available in the 🎯 Question Papers + YouTube Explanation section.
Proficiency Check
Learn – Unlearn – Relearn Approach
If you believe you have already mastered the Trial Balance, attempt the following without referring to notes.
If you are unable to answer confidently, revisit the lesson before proceeding.
A Trial Balance totals £75,000 on both sides. Later, a purchase of goods £5,000 was omitted completely. Will the Trial Balance still agree? Explain.
A debit entry of £2,500 was wrongly recorded as £5,200. How will this affect the Trial Balance?
Distinguish between an error of principle and an error of omission.
Why is the Trial Balance not a proof of complete accuracy?

Wages £5,000 – Credit Cash
Deposit £10,000 – Credit Cash / Debit Bank
Solutions to Proficiency Check
Solutions to Proficiency Check
Yes. If a transaction is omitted completely, both debit and credit are missing. The Trial Balance will still agree.
Totals will not agree because debit side is overstated.
Error of principle – Correct amount posted to wrong type of account.
Error of omission – Transaction not recorded at all.
It checks arithmetic accuracy only, not logical correctness.
Marking Logic
2 marks – Correct explanation
2 marks – Logical reasoning
2 marks – Evaluation
