Unadjusted Trial Balance: Example and Common Errors

Unadjusted trial balance with debit and credit columns — Farhat Lectures

An unadjusted trial balance is a list of a company’s general ledger accounts and their ending balances, prepared after journal entries are posted but before period-end adjusting entries. Total debits should equal total credits. Equal totals confirm the math, not that every transaction was recorded correctly. Adjusting entries then produce the adjusted trial balance.

Why it matters: This checkpoint helps students locate recording and posting errors before moving to adjustments. It also organizes the account balances that later support financial reporting.

What does an unadjusted trial balance show?

A trial balance is an internal accounting schedule, not a financial statement. It lists account titles and their balances at a specific date. Debit balances go in one column and credit balances in another. The word “unadjusted” tells you when the schedule is prepared: after posting, but before period-end adjusting entries. It does not mean the balances are wrong. It means some of them may still need updating.

Quick vocabulary check: the general ledger is the complete set of a company’s accounts. Posting means transferring each journal entry’s amounts into those ledger accounts. Adjusting entries are end-of-period entries that update balances, such as recording insurance that has expired, so revenues and expenses land in the correct period.

The preparation sequence is analysis, journalizing, posting, and then the trial balance. The journalizing and posting example explains how the underlying accounts are built. If an entry uses the wrong account, returning to transaction analysis is more useful than repeatedly adding the columns.

According to the IRS overview of double-entry bookkeeping, total debits must equal total credits after journal entries are posted to the ledger. OpenStax’s trial-balance lesson shows how final ledger balances move onto the schedule.

How to prepare an unadjusted trial balance

Preparation and review process
StepWhat to do
1. Finish postingConfirm that each recorded journal entry has reached every affected ledger account.
2. Calculate balancesNet each account’s debit and credit postings, including its opening balance.
3. List the accountsFollow the chart-of-accounts order: assets, liabilities, equity, dividends, revenues, and expenses.
4. Place each balanceUse the debit column for an actual debit balance and the credit column for an actual credit balance.
5. Total and investigateAdd both columns. If they differ, trace the difference without inserting an unsupported amount.

Use the company’s name, the schedule name, and an as-of date in the heading. A zero-balance account may be omitted or displayed without an amount, depending on the format. Do not enter an account’s gross debit activity in one column and gross credit activity in the other: the schedule uses its net ending balance.

Unadjusted trial balance example: Meridian

Hypothetical example. Meridian Design Studio Inc. starts with zero balances in May 20X7. After posting the transactions in the connected journal tutorial, its ledger contains the balances below. The example excludes income taxes and period-end adjustments. All amounts are U.S. dollars. Retained Earnings does not appear because May is Meridian’s first month, so its beginning balance is zero. An established company would list its beginning Retained Earnings balance with the other equity accounts.

Meridian Design Studio Inc. — Unadjusted Trial Balance — May 31, 20X7
AccountDebitCredit
Cash$21,000—
Accounts Receivable$2,000—
Supplies$1,200—
Prepaid Insurance$1,800—
Equipment$9,000—
Notes Payable—$6,000
Accounts Payable—$500
Unearned Service Revenue—$2,400
Common Stock—$24,000
Dividends$400—
Service Revenue—$5,000
Rent Expense$900—
Salaries and Wages Expense$1,600—
Total$37,900$37,900

Cash equals $29,400 of receipts less $8,400 of payments, or $21,000. Accounts Receivable equals $3,000 billed less $1,000 collected, or $2,000. Accounts Payable equals $1,200 purchased on account less $700 paid, or $500. These are ending balances, not new journal entries.

Total debit balances and credit balances both equal $37,900. This amount is not total assets or net income. It combines different account categories for a bookkeeping check. Dividends and expenses appear on the debit side even though they are not assets.

Errors a balanced trial balance can miss

Assume each error is considered separately
ErrorDo totals still agree?Why
Omit an entire $450 cash service transactionYesNeither the debit nor the credit is recorded.
Post both sides of a $900 rent entry twiceYesDebits and credits are overstated equally.
Debit Supplies instead of Equipment for a $700 cash purchaseYesThe amount and side balance, but the account classification is wrong.
Record a $640 transaction as $460 on both sidesYesBoth sides use the same incorrect amount.
Omit only a $300 debit posting while keeping its creditNoThe two sides no longer have equal totals.

Different mistakes can also offset one another. For that reason, a balanced trial balance is evidence of mathematical equality only. Review source documents, entry dates, account classifications, and completeness. A computer’s balanced-entry control helps with arithmetic but cannot decide whether the business event was understood correctly.

What if the debit and credit totals differ?

First add the columns again and compare each listed balance with the ledger. Then recalculate the ledger balances and trace entries back to the journal. Look for a missing account, a posting on the wrong side, or a copied amount that differs from the original. Never force agreement by putting the unexplained difference into Cash or another account.

For example, if a $250 debit balance is mistakenly listed as a credit, debits fall $250 while credits rise $250. The resulting difference is $500. This illustrates why an imbalance can be twice the amount of the underlying error. A handy shortcut: divide the difference by 2 and look for a balance of that amount sitting in the wrong column. Here, $500 ÷ 2 = $250.

If the difference divides evenly by 9, check for a transposition, where two digits are swapped on one side only. For example, if a $640 debit is posted as $460 while its $640 credit is posted correctly, the columns differ by $180, and $180 ÷ 9 = 20. A slide, such as posting $250 as $25, also creates a difference divisible by 9 ($225 ÷ 9 = 25).

Such patterns are clues; they do not replace inspection of the records.

Trial balance versus balance sheet

The trial balance includes revenue, expense, and dividend accounts alongside assets, liabilities, and equity. A balance sheet presents financial position using assets, liabilities, and equity. Its columns and subtotals serve a different purpose.

Unadjusted vs. Adjusted vs. Post-Closing Trial Balance

An unadjusted trial balance is prepared before period-end adjusting entries. An adjusted trial balance is prepared after those entries are posted, and it is the one used to prepare the financial statements. A post-closing trial balance comes last, after closing entries, and lists only permanent accounts.

Three trial balances in the accounting cycle
Unadjusted trial balanceAdjusted trial balancePost-closing trial balance
When it’s preparedAfter regular journal entries are posted, before adjusting entriesAfter adjusting entries are postedAfter closing entries are posted
Accounts listedEvery account with a balance: assets, liabilities, equity, dividends, revenues, and expensesThe same accounts with updated balances, plus any accounts the adjustments create, such as Depreciation ExpensePermanent accounts only: assets, liabilities, and equity
Main purposeCheck debit-credit equality and spot balances that need adjustingServe as the source for the financial statementsConfirm the books are ready for the next period

Think of Meridian’s Prepaid Insurance ($1,800) and Supplies ($1,200). If some insurance coverage expired or some supplies were used during May, those balances will change once adjusting entries are recorded. Equal unadjusted totals don’t remove the need for that review. Calculating the adjustments is outside this lesson.

For the final step in the cycle, see the post-closing trial balance guide.

Key Takeaways

  • An unadjusted trial balance lists each ledger account’s ending balance after posting and before adjusting entries.
  • Debit balances go in the left column and credit balances in the right. The two totals should match.
  • Equal totals prove the math, not that every entry is correct or complete.
  • Omitted, duplicated, misclassified, or equally misstated entries can all hide inside a balanced trial balance.
  • Financial statements are prepared from the adjusted trial balance, not the unadjusted one.
  • If the totals differ, trace the difference. Never plug it into Cash or another account.

Review: Trial balance definition, purposes, and preparation

What is a trial balance?

A trial balance is a list of accounts and their balances at a given time. A company usually prepares it at the end of an accounting period, such as the end of the month.

How are accounts and balances arranged?

Accounts appear in the same order as in the ledger. Debit balances are listed in the left column, and credit balances are listed in the right column. The totals of the two columns must agree.

What are the purposes of a trial balance?

A trial balance proves the mathematical equality of debits and credits after posting to the ledger. Under the double-entry system, this equality occurs when the sum of debit account balances equals the sum of credit account balances. A trial balance can help uncover some journalizing and posting errors and provides a starting point for financial-statement preparation. Equal totals do not prove that transactions are complete, correctly classified, or recorded at the correct amounts.

What are the steps in preparing a trial balance?

  1. List the account titles and their balances.
  2. Total the debit and credit columns.
  3. Prove the equality of the two columns.

Practice questions with answers

Try each question before reading its answer.

1. Cash has debit postings of $8,500 and credit postings of $3,200, with a zero opening balance. What belongs on the trial balance?

Answer: A $5,300 debit balance. Subtract credits from debits; do not list both gross totals as the account balance.

2. A complete $600 cash-revenue entry is omitted. Will the trial balance necessarily fail to balance?

Answer: No. Both Cash and Service Revenue are understated by $600, so the columns can remain equal even though the records are incomplete.

3. Debit balances total $18,700. Known credit balances total $15,900, and one verified credit-balance account is missing. What is its balance?

Answer: $2,800 credit: $18,700 − $15,900. This calculation works because the question establishes that only this account is missing and the other balances are correct. It is not permission to insert a balancing figure into real records.

Frequently asked questions

Is an unadjusted trial balance a balance sheet?

No. It is a debit-credit schedule of ledger balances. A balance sheet is a financial statement presenting assets, liabilities, and equity.

Should expenses be removed before preparing the trial balance?

No. Include their actual balances. Expenses, revenues, and dividends are temporary accounts, which means they are reset to zero through closing entries at the end of the period. That happens later in the accounting cycle, after the adjusted trial balance.

Does a credit balance always belong to a liability?

No. Revenue, common stock, and retained earnings normally have credit balances too, and so do contra-asset accounts such as Accumulated Depreciation. Use the account’s identity and actual balance, not the word credit alone.

What is the difference between an unadjusted and an adjusted trial balance?

Timing. The unadjusted trial balance is prepared before period-end adjusting entries, and the adjusted trial balance is prepared after them. The adjusted version is the one used to prepare financial statements.

Can you prepare financial statements from an unadjusted trial balance?

You shouldn’t. Its balances don’t yet reflect period-end adjustments such as expired insurance or supplies used, so revenues, expenses, assets, and liabilities could be misstated. Use the adjusted trial balance instead.

When is an unadjusted trial balance prepared?

Usually at the end of an accounting period, such as a month, quarter, or year, after all regular journal entries have been posted. A company can also prepare one at any time to check that debits equal credits.

What does an abnormal balance mean on a trial balance?

An abnormal balance is one on the opposite side from the account’s normal balance, such as Cash with a credit balance. It often signals a posting error, although a credit balance in Cash can also mean the bank account is overdrawn. Investigate it before moving on.
