Trial balance: format & how to prepare it.

What is a trial balance?

A trial balance is a statement that lists the closing balance of every ledger account on a particular date — usually the last day of the accounting period — split into two columns: Debit and Credit. It is prepared straight after you've posted all journal entries to the ledger and worked out each account's closing balance.

Think of it as the accountant's checkpoint. Before you build the Trading Account, Profit & Loss Account and Balance Sheet, you pause and ask: "Do my books actually balance?" The trial balance answers that question in one glance — if total debits equal total credits, you have arithmetical confidence to move on to the final accounts.

Why prepare a trial balance? The rule behind it

Every transaction in double-entry bookkeeping is recorded twice — once as a debit, once as an equal credit — across two different accounts. This is the duality principle. If every entry has been journalised and posted correctly, then when you add up all the debit balances in the ledger and separately add up all the credit balances, the two totals must be equal.

As a quick rule of thumb for which column an account's balance goes into: assets, expenses, losses and drawings normally carry debit balances; liabilities, capital, income and gains normally carry credit balances.

Worked example: trial balance of Sharma Traders

Sharma Traders is a sole proprietorship. After posting the year's transactions and balancing every ledger account, here is the trial balance as on 31 March. Notice the debit and credit columns tie out exactly — that's the whole point.

Both columns total ₹9,45,000 — the trial balance agrees. Sharma Traders can now proceed to prepare the Trading & Profit and Loss Account (using Purchases, Sales, Sales returns, Purchase returns, opening stock, Salaries, Rent, Interest and Discount received) and the Balance Sheet (using Capital, Drawings, Furniture, Sundry debtors, Sundry creditors, Bank loan and Cash at bank).

Common mistakes & student tips

• Posting a debit entry to the credit column (or vice versa) of the trial balance itself — the ledger was correct, the transcription wasn't.
• Forgetting to carry forward the closing balance of an account, so it's simply missing from the list.
• Adding the two columns wrongly — always re-check the addition before hunting for a 'missing' entry.
• Treating the trial balance as proof of accuracy. It only proves debits = credits; it can't catch a transaction left out entirely from both sides, or one posted to the wrong account (e.g. Rent debited instead of Salaries — a genuine error of principle that still balances).
• Mixing up which accounts are normally debit balances vs credit balances — students often flip Sales returns (a debit, being a reduction of sales) and Purchase returns (a credit, being a reduction of purchases).

Exam tip: if your trial balance doesn't tally, first re-check your additions, then confirm every ledger account's balance has actually been carried into the list — a missing account is the single most common cause in student answer papers.
