Trial Balance Class 11: Balance Method, Classification of Balances and Locating Errors

Updated 17 October 2026 · Fact-checked

A trial balance is a statement of the debit and credit balances of all ledger accounts on a given date, drawn up to check the arithmetic accuracy of the double-entry books. Assets, expenses, drawings and losses have debit balances; liabilities, capital, incomes and gains have credit balances. If the totals agree, the books are arithmetically accurate, but some errors still remain hidden.

Learn which items go on each side; equal totals prove only arithmetic accuracy, while errors of omission, principle, compensating and reversal stay hidden.

Understand Preparing a Trial Balance by the Balance Method and Locating Errors

Meaning and objectives. The trial balance proves that for every debit there is an equal credit (dual aspect), helps in preparing the final accounts and helps to locate errors.

Balance method. List every ledger account with its closing balance in the debit or credit column. Opening stock is a debit balance; closing stock, if given outside the trial balance, is not included.

Which side?

*Debit*: cash, bank, debtors, stock (opening), land and building, machinery, furniture, purchases, sales return, wages, rent, salaries, discount allowed, bad debts, drawings, interest paid, carriage inwards.
*Credit*: capital, creditors, bills payable, bank loan, sales, purchases return, discount received, interest received, commission received, rent received.
A bank overdraft is a credit balance.

What a balanced trial balance shows. Arithmetic accuracy only.

Errors NOT disclosed by the trial balance. (a) Errors of omission (a transaction wholly omitted); (b) errors of commission such as posting to the wrong account of the same type; (c) errors of principle (capital item treated as revenue); (d) compensating errors; (e) complete reversal of entries. Errors disclosed: posting on the wrong side, wrong amount in one account, wrong total, omission of one aspect, an account balance omitted or carried wrongly.

Locating a difference. Find the difference. (1) If it is divisible by 9, suspect a transposition. (2) If it is divisible by 2, look for a wrong side posting of half the amount. (3) If it equals a single amount, look for a one-sided entry or an omitted balance. (4) Re-total the books and recheck carry-forwards. Unlocated differences are placed in a suspense account to let the final accounts be prepared.

Preparing a Trial Balance by the Balance Method and Locating Errors in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

A tailor's balances

Suppose a tailor's ledger shows cash ₹6,000 (debit), creditors ₹14,000 (credit) and sales ₹70,000 (credit), and the trial balance is out by ₹90 which is divisible by 9.

What might have happened?

Try it first, then show the solutionSolution

A difference of 90 is divisible by 9, so a transposition is likely.
Example: ₹540 written as ₹450 (or ₹1,560 written as ₹1,650) in one account; each gives a difference of ₹90.

Answer: Suspect a transposition of digits in one entry.

Memory hook: Divisible by nine: digits switched.

Example 3: Prepare the trial balance · 5 marks · Long answerHarder board level

Prepare a trial balance on 31 March from these balances: capital ₹2,60,000; drawings ₹20,000; cash ₹15,000; bank ₹85,000; debtors ₹60,000; creditors ₹45,000; stock (1 April) ₹40,000; purchases ₹2,10,000; sales ₹3,80,000; purchases return ₹10,000; sales return ₹15,000; rent ₹24,000; salaries ₹36,000; furniture ₹70,000; machinery ₹1,80,000; bank loan ₹60,000. (5 marks)

Try it first, then show the solutionSolution

Debit: drawings 20,000; cash 15,000; bank 85,000; debtors 60,000; stock 40,000; purchases 2,10,000; sales return 15,000; rent 24,000; salaries 36,000; furniture 70,000; machinery 1,80,000. Total ₹7,55,000.
Credit: capital 2,60,000; creditors 45,000; sales 3,80,000; purchases return 10,000; bank loan 60,000. Total ₹7,55,000.
Both totals agree at ₹7,55,000.

Answer: Debit total = credit total = ₹7,55,000.

Example 4: Missing balance · 4 marks · Short answerHarder board level

The debit balances of a trial balance total ₹6,42,000 and the credit balances other than capital total ₹3,85,000. Find the capital. A clerk then finds the creditors balance of ₹28,000 has been left out of the credit column; find the capital again. (4 marks)

Try it first, then show the solutionSolution

With the original figures: capital = 6,42,000 − 3,85,000 = ₹2,57,000.
If creditors ₹28,000 should also be in the credit column, other credits become 3,85,000 + 28,000 = ₹4,13,000.
Capital = 6,42,000 − 4,13,000 = ₹2,29,000.

Answer: Capital ₹2,57,000 first; ₹2,29,000 after including creditors.

Example 5: Locate the difference · 4 marks · Short answerHOTS / competency

The debit side of a trial balance exceeds the credit side by ₹1,800. The accountant finds that a purchases return of ₹900 was posted to the debit side of the Purchases Return A/c instead of the credit side. Verify that this explains the difference, and state the rectifying entry. (4 marks)

Try it first, then show the solutionSolution

Correct posting would credit 900; wrongly it was debited 900.
Debit total is 900 too high and credit total 900 too low: difference = 900 + 900 = ₹1,800.
Rectification: the account needs a credit of 1,800 (cancel the wrong debit 900 and post the credit 900). Entry: Suspense A/c Dr 1,800; To Purchases Return A/c 1,800.

Answer: Difference 1,800 = 2 × 900; Dr Suspense 1,800, Cr Purchases Return 1,800.

Where students lose marks in Preparing a Trial Balance by the Balance Method and Locating Errors

The slips examiners see most often, and what to write instead.

Mistake: Putting sales return on the credit side
Thinking return is like sales.
Wrong working
Sales return in the credit column.
Right working
Sales return in the debit column.
Do this: Sales return reduces sales, so it carries a debit balance.
Usually costs: 1 mark
Mistake: Including closing stock in the trial balance
Closing stock is not a ledger balance.
Wrong working
Closing stock ₹50,000 in the debit column.
Right working
Closing stock is shown outside the trial balance (in the adjustments).
Do this: Only opening stock appears in the trial balance.
Usually costs: 1 mark
Mistake: Claiming a balanced trial balance means no errors
Mixing arithmetical accuracy with correctness.
Wrong working
The books are free of errors.
Right working
The books are arithmetically accurate; errors of omission, commission, principle and compensating may remain.
Do this: Always add this remark.
Usually costs: 1 mark

Exam tips

Show the two totals clearly and state "agree".
If asked "why may errors remain", name all four hidden types with one example each.
Write the difference and the hint you used to locate it.
Do not list closing stock or accrued items as part of the ordinary trial balance unless given.

Practice questions on Preparing a Trial Balance by the Balance Method and Locating Errors

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

Q1 · 1 mark · MCQBoard level
A trial balance is prepared to check:
(a) the profit
(b) the arithmetical accuracy of the books
(c) the cash balance
(d) the closing stock
Hint
Arithmetic.
Answer
(b) the arithmetical accuracy of the books
Q2 · 3 marks · Short answerHarder board level
The trial balance totals are: debit ₹5,64,200, credit ₹5,62,400. Find the difference and explain two ways in which it can arise. (3 marks)
Hint
Difference = 1,800.
Answer
Difference = ₹1,800 (debit higher). It can arise because an amount of ₹900 was posted on the wrong side (double effect of 1,800), or because a credit of ₹1,800 was omitted from one account or from the trial balance.
Q3 · 3 marks · Short answerHarder board level
Give the effect (disclosed or hidden) and the reason for: (i) a credit sale of ₹3,000 posted to the debtor's account as ₹300; (ii) rent paid ₹2,000 debited to the landlord's personal account; (iii) goods taken by the owner ₹1,000 credited to purchases only. (3 marks)
Hint
Count the two aspects.
Answer
(i) Disclosed: one account has the wrong amount. (ii) Hidden: the debit and the credit are both ₹2,000 and only the account debited is wrong (error of commission). (iii) Disclosed: only one aspect (credit to purchases) is posted; the debit to drawings is missing.
Q4 · 1 mark · Assertion-reasonHarder board level

Reason (R): The effect of one error is offset by an opposite error of the same amount.
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Hint
Offsetting.
Answer
(a) Both A and R are true, and R is the correct explanation of A.
Q5 · 4 marks · Short answerHOTS / competency
After preparing the trial balance of a firm, the accountant finds that debit total exceeds credit total by ₹540. Which of the following can explain it, and why can the other not? (a) A credit sale of ₹540 omitted from the sales book; (b) a receipt of ₹270 from a debtor posted to the debit of the debtor's account instead of credit and cash correctly debited; (c) both. (4 marks)
Hint
Check which side.
Answer
(b) is the answer: wrong-side posting of ₹270 gives difference 2 × 270 = ₹540 with debits higher. In (a) the whole transaction is omitted from the books (no debtor debit and no sales credit), so totals still agree and there is no difference. Therefore only (b) explains it.
