Trial Balance: Format, Example and How to Prepare One
See the trial balance format, follow a worked example that balances to the cent, and learn how to prepare one, adjust it and track down errors quickly.
Quick answer: A trial balance is a list of every ledger account with its closing balance shown in a debit or credit column. If total debits equal total credits, the books are arithmetically in balance. It is prepared at period end, before adjustments and financial statements, and it does not catch every kind of error.
This report is the checkpoint between day-to-day bookkeeping and the reports you show a lender or tax preparer. This guide gives you a format you can copy, a fully worked example that balances, the difference between unadjusted, adjusted and post-closing versions, and a practical method for tracking down a difference when the columns refuse to agree.

What is a trial balance?
Under double-entry bookkeeping, every transaction is recorded with equal debits and credits. If that rule was followed, then adding up all the debit balances in the ledger and all the credit balances should give the same number. The trial balance is simply that test, laid out as a report.
It is called a "trial" because it is a working check, not a finished statement. Owners rarely see it; accountants use it constantly. It does three jobs:
- Arithmetic check. Equal totals confirm that the ledger is mathematically consistent.
- Summary of balances. One page shows every account, which makes unusual numbers easy to spot.
- Bridge to the statements. The adjusted version is the source for the profit and loss statement and balance sheet.
Trial balance format
The standard layout has four columns. Accounts are listed in chart-of-accounts order: assets, liabilities, equity, revenue, expenses.
| Account no. | Account name | Debit | Credit |
|---|---|---|---|
| 1000 | Cash | Balance | |
| 1100 | Accounts receivable | Balance | |
| 2000 | Accounts payable | Balance | |
| 3000 | Owner's capital | Balance | |
| 4000 | Revenue | Balance | |
| 5000 | Expenses (each listed) | Balance | |
| Totals | Sum | Sum |
The heading should state the business name, "Trial Balance", and the date, for example "as of April 30, 2026". Each balance goes on the side of the account's normal balance:
| Account type | Normal balance column |
|---|---|
| Assets, expenses, owner's draws or dividends | Debit |
| Liabilities, equity, revenue | Credit |
| Contra-assets (accumulated depreciation, allowance for doubtful accounts) | Credit |
How to prepare a trial balance step by step
- Record everything for the period. Every invoice, bill, payment, payroll run and bank fee should be in the books as a journal entry.
- Post to the ledger. Software does this automatically. On paper, post each entry to its accounts in the general ledger.
- Reconcile key accounts. Match cash to the bank statement with a bank reconciliation, and check that receivables and payables agree with the customer and supplier lists.
- Find each closing balance. For each account, total the debits and credits and take the difference.
- List the balances. Put each one in the debit or credit column according to its normal balance. Include accounts with zero balances only if your format requires it.
- Total both columns. If they match, move on to adjustments. If not, investigate before going further.
Trial balance example
Here is an illustrative unadjusted listing for the fictional Cedar Lane Design as of April 30. The figures are invented to show the method.
| Account | Debit | Credit |
|---|---|---|
| Cash | $12,400 | |
| Accounts receivable | $5,600 | |
| Equipment | $6,000 | |
| Accumulated depreciation | $500 | |
| Accounts payable | $1,900 | |
| Sales tax payable | $450 | |
| Loan payable | $4,000 | |
| Owner's capital | $15,000 | |
| Owner's draws | $2,000 | |
| Service revenue | $18,500 | |
| Rent expense | $3,000 | |
| Wages expense | $9,000 | |
| Software expense | $650 | |
| Utilities expense | $900 | |
| Depreciation expense | $500 | |
| Interest expense | $300 | |
| Totals | $40,350 | $40,350 |
Checking the debit column: $12,400 + $5,600 = $18,000; + $6,000 = $24,000; + $2,000 = $26,000; + $3,000 = $29,000; + $9,000 = $38,000; + $650 = $38,650; + $900 = $39,550; + $500 = $40,050; + $300 = $40,350.
Checking the credit column: $500 + $1,900 = $2,400; + $450 = $2,850; + $4,000 = $6,850; + $15,000 = $21,850; + $18,500 = $40,350.
Both columns total $40,350, so the ledger is in balance. Notice two details: sales tax collected sits in a liability, not revenue, and owner's draws are a debit to equity, not an expense. Depreciation appears because the studio records it monthly; our guide on how to calculate depreciation explains where that $500 comes from.
Unadjusted, adjusted and post-closing versions
| Version | When | What it contains |
|---|---|---|
| Unadjusted | After posting routine transactions | All accounts before period-end adjustments |
| Adjusted | After adjusting entries | All accounts, updated for accruals, deferrals and depreciation; used for the statements |
| Post-closing | After closing entries at year-end | Only balance sheet accounts; revenue and expenses are zero |
Adjusting example
Suppose Cedar Lane finished $800 of work in April but will not invoice it until May. Under accrual accounting, the revenue belongs in April. The adjusting entry debits accrued revenue (an asset) $800 and credits service revenue $800. The adjusted totals become $40,350 + $800 = $41,150 in each column. The difference between earned-but-unbilled revenue and cash received in advance is covered in deferred revenue vs accrued revenue.
From the adjusted listing, revenue of $19,300 ($18,500 + $800) less expenses of $14,350 ($3,000 + $9,000 + $650 + $900 + $500 + $300) gives net income of $4,950. That figure becomes the bottom line of the profit and loss statement, and the asset, liability and equity balances feed the balance sheet.
What balanced totals do not prove
Equal totals are necessary but not sufficient. These errors leave the columns balanced:
| Error type | Example |
|---|---|
| Omission | A supplier bill was never entered at all. |
| Commission | A payment from Client A was applied to Client B's receivable. |
| Principle | A computer purchase was recorded as office supplies expense instead of equipment. |
| Original entry | An invoice for $1,250 was entered as $1,520 on both sides. |
| Reversal | The debit and credit accounts were swapped. |
| Compensating | Two unrelated mistakes of the same amount cancel out. |
That is why reconciliations, a review of the customer aging list and a sense-check against last month are part of every close.
Trial balance vs balance sheet vs general ledger
These three are easy to mix up because they draw on the same numbers.
| Report | What it lists | Who uses it |
|---|---|---|
| General ledger | Every posting to every account, with running balances | Bookkeepers and auditors tracing detail |
| Trial balance | One closing balance per account, in debit and credit columns | Bookkeepers and accountants checking and summarizing |
| Balance sheet | Assets, liabilities and equity only, in a formal layout | Owners, lenders, investors and tax authorities |
Think of them as levels of zoom. The ledger is the full detail, the trial listing is the one-page summary, and the balance sheet and P&L are the polished reports built from that summary. When a figure on the balance sheet looks wrong, you work backward: find the account on the trial listing, then open its ledger detail to see which postings created the balance.
Recordkeeping and who prepares it
Most small businesses do not prepare this listing by hand. Accounting software produces one on demand, and a bookkeeper or accountant reviews it at month-end or year-end. If you keep books in a spreadsheet, you will build it yourself with a SUMIF or pivot table that totals debits and credits by account. Either way, keep the supporting records. The IRS guide Publication 583, Starting a Business and Keeping Records explains the kinds of records US businesses should retain to support the figures in their books; other countries publish similar guidance.
How to find the difference when it does not balance
- Calculate the difference. Subtract the smaller total from the larger.
- Search for that amount. A whole balance may be missing from the listing.
- Divide by 2. If a $300 debit was listed as a credit, the totals differ by $600. Look for a $300 balance on the wrong side.
- Divide by 9. A difference that divides evenly by 9 often points to transposed digits ($540 entered as $450 creates a $90 gap) or a misplaced decimal.
- Re-add both columns. Simple addition errors are more common than anyone admits.
- Check that each journal entry balances. Spreadsheets will happily accept a one-sided entry; software usually will not.
If you use accounting software and the totals still disagree, the cause is usually an imported opening balance, a manual entry made outside the normal workflow, or a corrupted conversion from an older system. Run the report for earlier dates to find the first month where the columns stopped agreeing, then review the manual entries posted in that month. Narrowing the date range is often faster than checking every account.
Common mistakes
- Treating a balanced report as proof the books are right. See the error table above.
- Listing contra accounts on the wrong side. Accumulated depreciation is a credit.
- Skipping the bank reconciliation first. You end up balancing numbers that are themselves wrong.
- Leaving a balance in suspense. Forcing the totals to agree through a suspense account just hides the problem.
- Preparing statements from the unadjusted version. Accruals, deferrals and depreciation will be missing.
Trial balance checklist
- All invoices for the period are recorded, with no gaps in numbering.
- All supplier bills, payroll and bank fees are recorded.
- Bank and card accounts are reconciled.
- Receivables and payables agree with their subledgers.
- Each balance is listed on its normal side, contra accounts included.
- Both columns are totaled and equal.
- Adjusting entries are posted and an adjusted version is produced.
- Unusual balances are investigated before statements go out, as part of the month-end close checklist.
Next step
A clean listing starts with complete revenue records, so issue every invoice promptly and record it the same day. For more on the reports built from your adjusted balances, browse the business finance guides.
Frequently asked questions
What is a trial balance in simple terms?
A trial balance is a list of every account in your ledger with its closing balance placed in either a debit column or a credit column. You total both columns. Under double-entry bookkeeping the totals should be equal, so matching totals give you basic assurance that entries were recorded with equal debits and credits. It is an internal working report, prepared before the financial statements, not something you usually publish.
Why is a trial balance prepared?
It is prepared to check the arithmetical accuracy of the ledger and to give a single, compact list of balances from which the profit and loss statement and balance sheet can be drafted. Accountants also use it as the starting point for adjusting entries, for reviewing unusual balances and for handing the books to a tax preparer or auditor. Most software can produce one in seconds for any date.
What errors are not revealed by a trial balance?
Several. An omitted transaction leaves both columns equally short. An entry posted to the wrong account of the same type, such as rent recorded as utilities, still balances. So does an entry recorded with the wrong amount on both sides, a reversed entry with debit and credit swapped, or two separate mistakes that happen to cancel out. That is why reconciliations and reviews are still needed after the totals agree.
What are the three types of trial balance?
The unadjusted trial balance is prepared from the ledger before period-end adjustments. The adjusted trial balance is prepared after adjusting entries for items such as depreciation, accruals and deferred revenue, and it is the version used to prepare financial statements. The post-closing trial balance is prepared after revenue and expense accounts are closed to equity, so it contains only balance sheet accounts.
What should I do if my trial balance does not balance?
Find the difference between the two totals first. Check whether that amount appears as a balance or transaction anywhere, since a balance may be missing. Halve it to see if an item was placed in the wrong column. If the difference divides evenly by 9, look for transposed digits, such as 540 typed as 450. Then recheck additions and confirm every journal entry balances on its own.
Is a trial balance the same as a balance sheet?
No. A trial balance lists every account, including revenue and expenses, in debit and credit columns, and is used internally. A balance sheet reports only assets, liabilities and equity in a structured format for owners, lenders and others. You prepare the balance sheet and profit and loss statement from the adjusted trial balance, so the trial balance comes first and the statements are built from it.
Which side does each account go on in a trial balance?
Accounts appear on the side of their normal balance. Assets, expenses and owner's draws normally carry debit balances and go in the debit column. Liabilities, equity and revenue normally carry credit balances and go in the credit column. Contra accounts are the exception: accumulated depreciation and an allowance for doubtful accounts are credit balances even though they relate to assets.
How often should a small business run a trial balance?
Run one at every month-end close, after reconciling bank and card accounts and before producing monthly reports. It takes seconds in accounting software, so many bookkeepers also run it mid-month when investigating a problem. At year-end, the adjusted trial balance is usually the document your accountant or tax preparer asks for first, along with the general ledger detail behind it.
