Trial Balance: Preparation, Errors and Limitations

Updated 10 October 2026 · Fact-checked

A trial balance is a list of all ledger account balances on a date, split into a debit column and a credit column. If the two totals agree, the books are arithmetically accurate under double entry. To solve questions, classify each balance as debit or credit, then total both columns.

Understand Trial Balance

Every transaction is recorded with equal debit and equal credit amounts. So if you add up all debit balances and all credit balances in the ledger, the two totals must be equal. A trial balance is the statement that checks this.

It is not a final account. It is a working list prepared at the end of a period, or any date, after ledger accounts are balanced. Each ledger account appears once, with its closing balance placed in the debit or credit column.

The usual rule: assets and expenses/losses carry debit balances. Liabilities, capital, incomes and gains carry credit balances. Drawings are debit. Sales returns are debit. Purchase returns are credit. Closing stock normally does not appear in a trial balance, because it is an adjustment. Opening stock does appear, on the debit side.

Agreement of totals shows only arithmetical accuracy. It does not prove the books are free of error. Some errors leave both sides equal, so the trial balance still tallies. These are errors not disclosed by it. Errors that change only one side, such as posting only one side of an entry, are disclosed because the totals differ.

A trial balance differs from a balance sheet. The trial balance lists all accounts, including expenses and incomes, and is a check. The balance sheet lists only assets, liabilities and capital, and shows financial position.

Key formulas to remember

Basic agreement rule
Total of debit balances = Total of credit balances
If true, the trial balance agrees. It does not prove the books are error-free.
Debit balances
Assets (excluding closing stock) + Expenses + Losses + Drawings + Opening stock + Purchases + Sales returns
These items go in the debit column.
Credit balances
Capital + Liabilities + Incomes + Gains + Sales + Purchase returns + Provisions
These items go in the credit column.
Difference in totals
Difference = |Total Dr − Total Cr|
Shows the amount to place in a suspense account if the difference cannot be traced.

How to solve Trial Balance questions

Use this method for any question that gives ledger balances or asks which errors a trial balance shows.

  1. 1List every account balance given in the question.
  2. 2Decide for each one whether it is a debit or credit balance using its nature: asset, expense, liability, capital, income.
  3. 3Watch for contra-looking items such as drawings, returns and provisions, and place them correctly.
  4. 4Write the balances in a debit and a credit column.
  5. 5Add each column separately.
  6. 6Compare totals. If they differ and the question asks for capital, the missing figure is the capital. Otherwise, an unexplained difference is not capital. Put it in a suspense account until the error is traced.
  7. 7For error questions, check whether the error affects both sides equally. If yes, it is not disclosed. If it changes only one side, it is disclosed.

Quickest way: Dr/Cr sorting and balancing figure

When to use it: Use for numerical MCQs that give balances and ask for a missing figure or the total.

  1. Mark each item D or C next to it in the question.
  2. Add only the side that has fewer items.
  3. Subtract from the other known side's total to get the missing figure.
  4. For error MCQs, ask one question: did the same amount go wrong on both sides? If yes, the trial balance still agrees.

Common mistakes in Trial Balance

  • Putting drawings in the credit column

    Students link drawings with capital, which is a credit.

    Fix: Drawings reduce capital but are a debit balance. Always place them in the debit column.

  • Including closing stock in the trial balance

    Stock looks like an asset, so it seems to belong.

    Fix: Closing stock is given outside the trial balance as an adjustment. Opening stock is the one in the debit column.

  • Treating purchase returns as debit

    The word purchases suggests debit.

    Fix: Purchase returns reduce purchases and carry a credit balance. Sales returns carry a debit balance.

  • Thinking an agreeing trial balance means no errors

    Students mix up arithmetical accuracy with complete accuracy.

    Fix: Remember that errors of omission, commission, principle, compensating errors and wrong-account postings can still leave totals equal.

  • Confusing trial balance with balance sheet

    Both list balances and both are prepared from ledgers.

    Fix: The trial balance includes incomes and expenses and is a check. The balance sheet has only assets, liabilities and capital.

Worked examples

Example 1

From the balances on 31 March, find the missing capital if the trial balance agrees: Cash ₹10,000; Debtors ₹30,000; Stock (opening) ₹20,000; Purchases ₹60,000; Sales ₹90,000; Creditors ₹25,000; Rent paid ₹5,000; Drawings ₹8,000; Capital ?

Show the solution
  1. Debit items: Cash 10,000 + Debtors 30,000 + Stock 20,000 + Purchases 60,000 + Rent 5,000 + Drawings 8,000.
  2. Total debit = ₹1,33,000.
  3. Known credits: Sales 90,000 + Creditors 25,000 = ₹1,15,000.
  4. Capital = 1,33,000 − 1,15,000 = ₹18,000.

Answer: Capital is ₹18,000.

Example 2

Which error will the trial balance disclose? (A) Goods sold to Ravi ₹5,000 not recorded at all (B) Purchase of furniture ₹10,000 debited to Purchases account (C) Rent account debit was overcast by ₹1,000 and Commission received account credit was overcast by ₹1,000 (D) Cash received from Meera ₹2,000 credited to Meera's account but not debited to cash

Show the solution
  1. Option A is a complete omission. Both debit and credit are missing, so the totals still agree.
  2. Option B is an error of principle. The debit is in the wrong account but the amount is the same, so the totals still agree.
  3. Option C is a compensating error. The Rent account debit is too high by ₹1,000 and the Commission received account credit is too high by ₹1,000. The extra debit and the extra credit cancel out, so the totals still agree.
  4. Option D records only the credit. The debit to cash is missing, so total credits exceed total debits and the trial balance is disturbed.

Answer: Option D. A one-sided posting is disclosed by the trial balance.

Exam tips

  • For a missing figure question, sort items into Dr and Cr first. Do not add everything together.
  • Learn the list of errors not disclosed: omission, commission in the wrong account, principle, compensating, and errors in the original entry (wrong amount recorded on both sides).
  • Remember that an error in totalling a subsidiary book, such as overcasting the sales book, makes the total posted to the ledger account differ from the sum of the individual postings on the other side. So the trial balance totals differ and the error is disclosed.
  • Check whether opening or closing stock is given. Only opening stock in the trial balance is a debit item.
  • If a question mentions a suspense account, the difference in totals went there and is cleared on rectification.

Trial Balance: frequently asked questions

What is the main purpose of a trial balance?

It checks the arithmetical accuracy of the ledger postings under double entry. It also makes it easier to prepare final accounts. It does not prove the books are completely correct.

What errors are not disclosed by a trial balance?

Errors of omission, errors of principle, compensating errors, and posting to a wrong account of the same type do not affect totals. Original entry errors with equal amounts on both sides also stay hidden.

What is the difference between a trial balance and a balance sheet?

A trial balance lists all ledger balances, including incomes and expenses, to check accuracy. A balance sheet shows only assets, liabilities and capital to present financial position. The trial balance is not a final statement.

Where do I put a difference in trial balance totals?

If you cannot find the error quickly, put the difference in a suspense account on the smaller side so the totals agree. Later you rectify the errors and close the suspense account.
