Purpose and Format of a Trial Balance
Updated 11 October 2026 · Fact-checked
A trial balance is a list of all ledger account balances at a date, with debit balances in one column and credit balances in the other. You prepare it by balancing each ledger account, listing each balance on its correct side and adding both columns. If the totals match, the ledgers are arithmetically balanced.
Understand Purpose and Format of a Trial Balance
Every transaction is recorded using double entry. Each entry has a debit and an equal credit. So if you add up all the debit balances in the ledgers and all the credit balances, the two totals should be equal.
A trial balance is the list you use to check this. It shows each ledger account name with its closing balance, placed in a debit column or a credit column. You then total both columns. It is not a financial statement. It is an internal working list.
The main purpose is to check the arithmetic accuracy of the double entry. If the totals differ, you know something is wrong, for example a one-sided entry, a posting error or an addition mistake. You then look for it before preparing the financial statements.
A second purpose is practical. The trial balance is the starting point for preparing the statement of profit or loss and the statement of financial position. It also gives you a list of all balances in one place, which is where year-end adjustments begin.
A matching trial balance does not prove the books are correct. Some errors leave both columns equal, such as an entry posted to the wrong account or a transaction omitted altogether. Those limits are covered in a separate topic.
To know which side a balance goes on, remember the normal balances. Assets and expenses are normally debit. Liabilities, capital (equity) and income are normally credit. Drawings are debit. Receivables are debit. Payables are credit. Allowance for receivables is credit.
Key formulas to remember
- Trial balance check
- Total debit balances = Total credit balances
- If equal, the double entry is arithmetically balanced. It does not prove there are no errors.
- Normal debit balances
- Assets + Expenses + Drawings = Debit
- Includes non-current assets, inventory, receivables, bank (if positive), purchases, wages, rent and drawings.
- Normal credit balances
- Liabilities + Capital/Equity + Income = Credit
- Includes payables, loans, share capital, reserves, sales, other income and allowance for receivables.
- Ledger account balance
- Balance = Total of larger side − Total of smaller side
- The balance sits on the side with the larger total. A debit larger than credit gives a debit balance.
- Accounting equation link
- Assets = Capital + Liabilities
- Explains why debits and credits agree when all entries are complete double entries.
How to solve Purpose and Format of a Trial Balance questions
Use this method for any question that asks you to prepare, complete or check a trial balance.
- 1List every ledger account given in the question, one per line.
- 2Find each closing balance. If you get ledger accounts, total each side and take the difference.
- 3Decide the side of each balance. Debit if it is an asset, expense or drawings. Credit if it is a liability, capital or income.
- 4Check unusual items. Bank overdraft is credit. Returns inwards are debit. Returns outwards are credit. Allowance for receivables is credit.
- 5Write each balance in the debit or credit column.
- 6Total both columns separately.
- 7Compare the totals. If they differ, find the difference and check for a missed or wrongly placed balance. If you are asked for a missing figure, it is the balancing figure that makes the totals agree.
Quickest way: Sort by type, then total
When to use it: Use this in objective test questions that give a list of balances and ask for a total or a missing figure.
- Do not rewrite the full trial balance. Draw two columns, Dr and Cr.
- Go through the list once, writing each amount in the correct column using the normal balance rule.
- Add the side that has fewer items first, then add the other.
- For a missing figure, the answer is the difference between the two totals. Put it on the lighter side.
- Check one risky item, such as an overdraft or returns, before you enter your answer.
Common mistakes in Purpose and Format of a Trial Balance
Putting a bank overdraft in the debit column.
Students link bank with assets, which are debit.
Fix: A positive bank balance is debit. An overdraft is a liability, so it is credit.
Treating drawings as a credit or as an expense in a separate column.
Drawings reduce capital, so students think they go with capital.
Fix: Drawings are a debit balance. They reduce capital, but the account itself carries a debit.
Listing the allowance for receivables as a debit next to receivables.
It looks like part of the receivables account.
Fix: The allowance is a separate account with a credit balance. List it on its own line in the credit column.
Thinking a balancing trial balance proves the books are right.
The word balance suggests accuracy.
Fix: It only proves debits equal credits. Errors of omission, commission, principle and compensating errors do not show up.
Putting the closing balance on the wrong side by using the wrong total.
Students rush when balancing T-accounts.
Fix: Add both sides, take the smaller from the larger, and place the balance on the larger side.
Forcing the trial balance to agree by putting the difference in a suspense account without checking.
It looks like a quick fix.
Fix: Suspense is a temporary holding account. Look for the error first. Use suspense only when the question tells you to.
Worked examples
Example 1
At 31 December, a business has these balances: Sales $98,000; Purchases $61,000; Rent $6,000; Wages $14,000; Receivables $12,000; Payables $9,000; Bank (overdraft) $3,000; Inventory at 1 January $8,000; Capital $?; Non-current assets $40,000; Drawings $5,000. Calculate the capital balance that makes the trial balance agree.
Show the solution
- Debit balances: Purchases 61,000 + Rent 6,000 + Wages 14,000 + Receivables 12,000 + Inventory 8,000 + Non-current assets 40,000 + Drawings 5,000.
- Add them: 61,000 + 6,000 = 67,000. 67,000 + 14,000 = 81,000. 81,000 + 12,000 = 93,000. 93,000 + 8,000 = 101,000. 101,000 + 40,000 = 141,000. 141,000 + 5,000 = 146,000.
- Credit balances given: Sales 98,000 + Payables 9,000 + Bank overdraft 3,000 = 110,000.
- Capital must make credits equal debits: 146,000 − 110,000 = 36,000.
Answer: Capital is $36,000 (credit balance). Both columns total $146,000.
Example 2
A ledger account for Rent paid shows debits of $2,400, $2,400 and $2,600, and a credit of $1,200 (rent refund). A Payables account shows debits of $18,500 and credits of $23,000. State the balance on each account and the column each goes in on the trial balance.
Show the solution
- Rent: total debits = 2,400 + 2,400 + 2,600 = 7,400.
- Rent credits = 1,200.
- Rent balance = 7,400 − 1,200 = 6,200. Debits are larger, so it is a debit balance.
- Payables: total credits = 23,000. Total debits = 18,500.
- Payables balance = 23,000 − 18,500 = 4,500. Credits are larger, so it is a credit balance.
Answer: Rent is $6,200 in the debit column. Payables is $4,500 in the credit column.
Exam tips
- In objective tests, work out the side of each balance first. Most wrong answers come from putting one item in the wrong column.
- Watch for items that look like they belong on one side but do not: overdraft, returns outwards, allowance for receivables and drawings.
- For a missing figure, find the difference between the two totals. Do not try to find it by reasoning about the business.
- If the question asks which error would stop the trial balance agreeing, check whether the error affects debits and credits unequally.
- Know the purpose in words. Expect questions asking what a trial balance does and does not prove.

Purpose and Format of a Trial Balance: frequently asked questions
What is a trial balance in ACCA FA?
It is a list of all ledger account balances at a point in time, split into debit and credit columns. If the total debits equal the total credits, the double entry is arithmetically balanced. It is prepared before the financial statements.
Is a trial balance a financial statement?
No. It is an internal list used to check the ledgers and to prepare the financial statements. It is not published and is not part of a full set of financial statements.
How do I prepare a trial balance from ledger accounts?
Balance each ledger account by totalling both sides and finding the difference. Write the balance in the debit column if debits are larger, or the credit column if credits are larger. Then total both columns and compare.
What if the trial balance does not balance?
Find the difference. Check addition, a balance placed on the wrong side, a one-sided entry or a missing balance. In some questions, the difference is put to a suspense account until the error is found.
