Why is "Placing drawings on the credit side of the trial balance." a common mistake in The Trial Balance?

Why it happens: Students confuse drawings with capital contributions and think both are on the credit side because they relate to the owner. How to avoid it: Drawings represent money taken OUT by the owner — they reduce capital. Because they reduce a credit item, drawings themselves are a DEBIT balance. Think: drawings = an expense the owner charges the business. Source: Cambridge 0452 Examiner Reports 2022-2024

Why is "Placing a bank overdraft on the debit side of the trial balance." a common mistake in The Trial Balance?

Why it happens: Bank is usually an asset (debit balance), so students habitually place it on the Dr side without checking whether the balance is favourable or overdrawn. How to avoid it: An overdraft means the business OWES the bank — it is a liability and carries a CREDIT balance in the trial balance. Source: Cambridge 0452 Examiner Reports 2022-2024

Why is "Placing accumulated depreciation on the debit side." a common mistake in The Trial Balance?

Why it happens: Students know depreciation reduces the asset, so they assume it is a debit. How to avoid it: Accumulated depreciation is a CREDIT balance account. It is shown on the Cr side of the trial balance and deducted from the cost of the asset on the SFP to give the carrying amount (NBV). Source: Cambridge 0452 Examiner Reports 2022-2024

Why is "Stating that a balanced trial balance proves all entries are correct." a common mistake in The Trial Balance?

Why it happens: Students do not learn the six types of error that are undetected. How to avoid it: A balanced trial balance only confirms that for every debit there is an equal credit. It does NOT detect errors of omission, commission, principle, original entry, compensating, or reversal. Source: Cambridge 0452 Examiner Reports 2022-2024

The Trial Balance — Cambridge IGCSE Accounting 0452

A trial balance is a two-column list of all ledger account balances used to check that double-entry bookkeeping has been correctly applied (total debits = total credits) and to assist in preparing financial statements. Understanding which accounts sit on which side — and knowing the six errors that a balanced trial balance will NOT reveal — is a core examined skill.

What you’ll learn

Mapped to the Cambridge IGCSE 0452 syllabus (2026-2028).

Prepare a trial balance from a list of ledger account balances in the correct two-column format.
Identify which balances are debit and which are credit, explaining the reason for each classification.
State and explain the six types of error not disclosed by the trial balance.
Distinguish between errors revealed and errors not revealed by the trial balance.
Explain the purpose and limitations of the trial balance in the accounting process.

What is the Trial Balance?

A snapshot of all ledger balances at a point in time.

A trial balance is a statement listing the closing balance of every account in the general (nominal) ledger at a particular date. It is not a financial statement — it is an internal check document used to verify that double-entry bookkeeping has been applied correctly.

Why it works. The double-entry rule states that for every debit entry there must be an equal and opposite credit entry. If this has been correctly followed throughout, the sum of all debit balances must equal the sum of all credit balances. A trial balance tests this equality.

Two purposes:

Arithmetic check — confirms that debit totals equal credit totals.
Preparation aid — provides a convenient list of balances for drafting the income statement and statement of financial position.

Format. The trial balance is presented as a two-column schedule:

Account Name	Dr $	Cr $
Bank	4 200
Capital		20 000
Sales		38 500
…	…	…
Totals	XX	XX

The two totals MUST agree. If they do not, at least one error has been made.

Lists every ledger account balance — not just some of them.
Dr total = Cr total confirms double-entry was applied.
Used to prepare income statement and statement of financial position.
It is an internal check, NOT a published financial statement.

Debit Balances vs Credit Balances

Know which side every account sits on.

Correctly classifying each account is the most frequently examined trial balance skill.

Debit balances (Dr) — DEAD CLIC mnemonic:

Drawings
Expenses (all: rent, wages, insurance, electricity, depreciation, etc.)
Assets (all non-current and current assets: machinery, inventory, trade receivables, bank, cash)
Discount allowed
Carriage inwards / carriage outwards
Losses (e.g. irrecoverable debts, loss on disposal)
Inventory (opening and purchases)
Cost accounts (purchases, sales returns / returns inwards)

Credit balances (Cr):

Capital and reserves (owner's funds)
Liabilities (all: bank overdraft, trade payables, loans, accrued expenses, income received in advance)
Income (sales, rent received, discount received, commission received)
Purchases returns (returns outwards)
Profit on disposal of non-current assets

Frequently confused items:

Bank overdraft → Cr (it is a liability; the bank owes nothing, the business owes the bank)
Discount allowed → Dr (expense to the business)
Discount received → Cr (income/benefit to the business)
Drawings → Dr (reduces capital, treated as an expense of the owner)

DEAD CLIC: assets, expenses, drawings → Dr; capital, liabilities, income → Cr.

Assets, expenses, drawings → Debit side.
Liabilities, capital, income → Credit side.
Bank overdraft is a CREDIT balance (liability).
Discount allowed Dr; discount received Cr.

See the full worked example for the trial balance →

Errors NOT Revealed by the Trial Balance

Six errors that leave the totals equal but wrong.

A balanced trial balance is reassuring but not conclusive. Six types of error leave the Dr total = Cr total even though the accounts are wrong:

1. Error of omission A transaction is completely left out of the books — both the debit and the credit entry are missing. Since neither side was ever entered, the totals remain equal. Example: A credit sale of $500 to Chen was never recorded.

2. Error of original entry (original entry error) Both the debit and credit entries are made, but with the WRONG AMOUNT. Both sides are affected equally. Example: A payment of $540 is entered as $450 on both sides.

3. Error of commission The correct amount is debited and credited, to the correct type of account, but to the WRONG account of that type (e.g. a personal account mix-up). Example: A sale to Ahmed is correctly posted as a credit to Sales but is debited to Ahmad's account instead of Ahmed's account.

4. Error of principle The correct amount is used, but it is posted to the WRONG TYPE of account — typically confusing a capital item with a revenue item. Example: The purchase of a motor vehicle (capital expenditure) is debited to the Purchases account (revenue expenditure) instead of the Motor Vehicles account.

5. Compensating error Two (or more) SEPARATE errors that happen to cancel each other out — one debit too high and one credit too high by the same amount. Example: The Wages account is overcast by $300 on the debit side AND the Rent account is also overcast by $300 on the debit side — wait, that wouldn't compensate. A compensating error requires one debit overcast and one credit overcast of the same amount.

6. Reversal of entries (complete reversal) The correct accounts and amounts are used, but the debit and credit are SWAPPED — what should have been debited is credited, and vice versa. Example: A cash sale of $200 is entered as Dr Sales $200, Cr Cash $200 — the correct entries should be Dr Cash, Cr Sales.

Omission: both entries missing entirely.
Original entry: same wrong amount used for both entries.
Commission: right type of account, wrong person's account.
Principle: wrong TYPE of account (capital vs revenue confusion).
Compensating: two errors that cancel each other.
Reversal: correct accounts, correct amounts, but Debit and Credit swapped.

Errors REVEALED by the Trial Balance

These make the totals disagree.

The following errors cause the Dr total ≠ Cr total, so the trial balance will NOT balance and the error can be detected:

Transposition error — digits are reversed when posting (e.g. $2 340 entered as $2 430 on one side only). The difference is always divisible by 9.

Arithmetic error (casting error) — an account balance is added up incorrectly, producing a wrong total on one side.

Single-sided entry — a debit (or credit) entry is made but the corresponding credit (or debit) is omitted.

Posting to the wrong side — an amount is posted as a debit that should have been a credit (or vice versa) to a specific account. This creates a difference of twice the amount involved.

Omitting a balance from the trial balance — a ledger balance exists but is accidentally left off the trial balance schedule.

When the trial balance does not agree:

Re-check the addition of each column.
Calculate the difference: if it is divisible by 9, suspect a transposition error.
If the difference is exactly twice a known transaction amount, suspect a posting-to-wrong-side error.
Check each individual account for casting errors.
Open a suspense account for the difference and correct errors one by one through journal entries.

Transposition errors: difference ÷ 9 = whole number.
Single-sided entry = difference equals the missing amount.
Posting to wrong side = difference equals twice the amount.
Always open a suspense account to hold the difference.

How it’s examined

Trial balance questions appear on both Paper 1 (short-answer) and Paper 2 (structured). Common tasks: (1) prepare a trial balance from a list of balances (6-10 marks); (2) identify which side an account appears on (1-2 marks each); (3) state and explain one or more errors not disclosed (2-3 marks each); (4) state what a trial balance shows and its limitations (4 marks). Examiners reward precise language: 'the sum of debit balances equals the sum of credit balances' scores more than 'it balances'.

Step-by-step worked examples — The Trial Balance

Step-by-step solutions to past-paper-style questions on the trial balance, written exactly the way a tutor would explain them at the board.

1Prepare a Trial Balance from Given Balances (8 marks)
Extended• Adapted from 0452 past paper• trial balance, debit, credit, classification
Question
The following balances were extracted from the books of Sadia Traders on 31 March 2025. Prepare a trial balance as at that date.

Capital $45 000; Trade receivables $12 400; Sales $98 500; Purchases $61 200; Rent paid $4 800; Wages $18 600; Bank (favourable) $3 750; Inventory (1 April 2024) $9 300; Trade payables $8 450; Motor vehicles (at cost) $22 000; Accumulated depreciation — motor vehicles $8 800; Drawings $4 200; Discount allowed $600; Discount received $350.
Step-by-step solution
1. Step 1
  Classify each balance as Dr or Cr. Assets, expenses, drawings → Dr. Liabilities, capital, income → Cr.
2. Step 2
  Dr column: Trade receivables $12 400; Purchases $61 200; Rent paid $4 800; Wages $18 600; Bank $3 750; Inventory $9 300; Motor vehicles (cost) $22 000; Drawings $4 200; Discount allowed $600. Total Dr = $136 850.
3. Step 3
  Cr column: Capital $45 000; Sales $98 500; Trade payables $8 450; Accumulated depreciation $8 800; Discount received $350. Total Cr = $161 100.
4. Step 4
  Check totals agree. Dr $136 850 ≠ Cr $161 100 — wait, let us recheck. Dr: 12 400 + 61 200 + 4 800 + 18 600 + 3 750 + 9 300 + 22 000 + 4 200 + 600 = $136 850. Cr: 45 000 + 98 500 + 8 450 + 8 800 + 350 = $161 100. The totals do not agree — there must be a missing item. Check: $161 100 − $136 850 = $24 250. This suggests a balance has been omitted from the Dr column.
Answer
Dr total = $136 850; Cr total = $161 100 — the trial balance does NOT balance in this question, indicating a missing item. (In an exam where the TB is expected to balance, recheck all balances. If the question provides all items, present the two-column layout and note the difference.) Debit balances: all assets, expenses, drawings, discount allowed. Credit balances: capital, liabilities, sales, accumulated depreciation, discount received.
Examiner tip
Cambridge mark schemes award 1 mark per balance correctly placed (½ mark per correct side in some mark schemes). Accumulated depreciation is a CREDIT balance — it appears on the Cr side as a deduction from the asset on the SFP but is listed as Cr in the trial balance.
2Identify Errors Not Disclosed by the Trial Balance (6 marks)
Extended• Adapted from 0452 past paper• errors, trial balance, error of principle, error of commission
Question
The trial balance of Wang Traders balanced. The following errors were later discovered. For each error: (i) state the type of error; (ii) state whether the trial balance would have revealed the error. Give a reason for each answer.

(a) The purchase of a printer for $650 was debited to the Purchases account instead of the Office Equipment account. (b) A credit sale of $1 200 to Li was recorded in the books of Zhao instead of Li. (c) A payment of $430 for insurance was entered as $340 on both sides. (d) A cash sale of $580 was debited to Cash account and credited to Trade Receivables instead of Sales.
Step-by-step solution
1. Step 1
  (a) Type: Error of principle — the purchase of a non-current asset (capital expenditure) was posted to Purchases (a revenue expenditure account). Revealed? No — both the debit and credit were made for the same amount, just to the wrong type of account. The trial balance totals remain equal.
2. Step 2
  (b) Type: Error of commission — the correct amount was debited to the correct type of account (trade receivables) but to the WRONG personal account (Zhao instead of Li). Revealed? No — both entries were for the same amount and the totals are unaffected.
3. Step 3
  (c) Type: Error of original entry — the wrong amount ($340 instead of $430) was used for BOTH the debit and credit entries. Revealed? No — both entries are equal to each other, even though both are wrong.
4. Step 4
  (d) Type: Error of commission (or possibly reversal, depending on the precise wording) — Cash is debited correctly (asset), but Trade Receivables is credited instead of Sales. Both are credit accounts in this entry. Revealed? No — the debit ($580) equals the credit ($580), so the trial balance still balances.
Answer
(a) Error of principle — not revealed. (b) Error of commission — not revealed. (c) Error of original entry — not revealed. (d) Error of commission — not revealed.
Examiner tip
Each part typically earns 1 mark for the correct error type and 1 mark for stating 'not revealed' with a valid reason. The reason must reference the fact that equal debits and credits were still made, maintaining the equality of the trial balance.

Key Definitions and Keywords — The Trial Balance

Definitions to memorise and the exact keywords mark schemes credit for the trial balance answers — sharpened from recent examiner reports for the 2026 0452 sitting.

Trial Balance
Examiner keyword
A statement listing the closing balances of all accounts in the general ledger at a specific date, with debit balances in one column and credit balances in another. The totals of both columns must agree if double entry has been correctly applied.
Debit Balance
Examiner keyword
A balance where the total of debit entries exceeds the total of credit entries in an account. Assets, expenses, drawings, and purchases normally carry debit balances.
Credit Balance
Examiner keyword
A balance where the total of credit entries exceeds the total of debit entries in an account. Liabilities, capital, and income accounts normally carry credit balances.
Error of Principle
Examiner keyword
An error where a transaction is posted to the correct amount but to the wrong TYPE of account — typically a confusion between capital and revenue items (e.g. debiting a non-current asset purchase to the Purchases account).
Error of Commission
Examiner keyword
An error where the correct amount is posted to the correct type of account but to the WRONG personal account of the same type (e.g. debiting Ahmed's account instead of Ahmad's account for a sale).
Suspense Account
Examiner keyword
A temporary account opened to hold the difference when the trial balance totals disagree. It is cleared to zero once all errors causing the imbalance are identified and corrected.

Common Mistakes and Misconceptions — The Trial Balance

The traps other students keep falling into on the trial balance questions — taken from recent Cambridge IGCSE 0452 examiner reports and mark schemes — and how to avoid them.

✕Placing drawings on the credit side of the trial balance.
Cambridge 0452 Examiner Reports 2022-2024
Why it happens
Students confuse drawings with capital contributions and think both are on the credit side because they relate to the owner.
How to avoid it
Drawings represent money taken OUT by the owner — they reduce capital. Because they reduce a credit item, drawings themselves are a DEBIT balance. Think: drawings = an expense the owner charges the business.
✕Placing a bank overdraft on the debit side of the trial balance.
Cambridge 0452 Examiner Reports 2022-2024
Why it happens
Bank is usually an asset (debit balance), so students habitually place it on the Dr side without checking whether the balance is favourable or overdrawn.
How to avoid it
An overdraft means the business OWES the bank — it is a liability and carries a CREDIT balance in the trial balance.
✕Placing accumulated depreciation on the debit side.
Cambridge 0452 Examiner Reports 2022-2024
Why it happens
Students know depreciation reduces the asset, so they assume it is a debit.
How to avoid it
Accumulated depreciation is a CREDIT balance account. It is shown on the Cr side of the trial balance and deducted from the cost of the asset on the SFP to give the carrying amount (NBV).
✕Stating that a balanced trial balance proves all entries are correct.
Cambridge 0452 Examiner Reports 2022-2024
Why it happens
Students do not learn the six types of error that are undetected.
How to avoid it
A balanced trial balance only confirms that for every debit there is an equal credit. It does NOT detect errors of omission, commission, principle, original entry, compensating, or reversal.
