Preparing a Trial Balance

Learn to prepare a trial balance from ledger accounts and use error-location techniques when debits don't equal credits.

Learning Objectives

By the end of this lesson, you will be able to:

  1. Explain the purpose of a trial balance.
  2. Prepare a trial balance from ledger account balances.
  3. Identify errors that cause a trial balance to not balance.
  4. Apply techniques to locate and correct trial balance errors.

Purpose of the Trial Balance

A trial balance is a list of all general ledger account balances at a specific point in time, with debit balances in one column and credit balances in another.

Its primary purpose is to verify that total debits equal total credits. If they don't, a posting error has occurred.

The trial balance is also the starting point for preparing financial statements — the income statement is prepared from revenue and expense accounts, and the balance sheet is prepared from asset, liability, and equity accounts.

Preparing a Trial Balance

To prepare a trial balance:

  1. List all accounts in the general ledger.
  2. Note each account's closing balance (debit or credit).
  3. Place debit balances in the debit column and credit balances in the credit column.
  4. Total both columns.
  5. Verify that the totals are equal.

Example trial balance for a UAE LLC:

| Account | Debit (AED) | Credit (AED) | |---------|-------------|-------------| | Cash | 350,000 | | | Accounts receivable | 120,000 | | | Inventory | 80,000 | | | Equipment | 200,000 | | | Accounts payable | | 90,000 | | Bank loan | | 150,000 | | Share capital | | 400,000 | | Sales revenue | | 300,000 | | Cost of sales | 180,000 | | | Salaries expense | 70,000 | | | Rent expense | 40,000 | | | Total | 1,040,000 | 940,000 |

The trial balance does not balance — there is a AED 100,000 difference. An error exists.

Errors That Cause Imbalance

If the trial balance does not balance, one or more of the following has occurred:

  1. One-sided posting — only the debit or credit side of an entry was posted.
  2. Different amounts — the debit and credit were posted with different amounts.
  3. Transposition error — digits were swapped (e.g., AED 52,000 written as AED 25,000).
  4. Incorrect carry-forward — a balance was brought forward incorrectly from a previous period.
  5. Omission of an account — an account balance was not listed in the trial balance.

Locating Errors

Several techniques help locate errors:

1. Divide the difference by 2

If the difference is exactly divisible by 2, an account balance may have been entered on the wrong side. For example, if a AED 50,000 credit balance was entered as a debit, the difference would be AED 100,000 (twice the amount).

2. Divide the difference by 9

If the difference is divisible by 9, a transposition error may have occurred. For example, if AED 45,000 was written as AED 54,000, the difference is AED 9,000 (divisible by 9).

3. Check for round numbers

If the difference is a round number (e.g., AED 1,000 or AED 10,000), check whether an entry of that amount was posted on only one side.

4. Re-check the ledger

Re-add each account's debit and credit totals to ensure no arithmetic error was made when calculating balances.

Correcting Errors

Once an error is found, it is corrected with a journal entry:

  • If an entry was omitted, post it.
  • If an amount was wrong, post a correcting entry for the difference.
  • If an entry was posted to the wrong side, reverse it and post it correctly.

After correction, the trial balance should balance.

Summary

A trial balance lists all account balances and verifies that total debits equal total credits. If it doesn't balance, a posting error has occurred. Techniques to locate errors include dividing the difference by 2 (wrong side), by 9 (transposition), and checking for round numbers (one-sided posting). Errors are corrected with journal entries.

Practical UAE example

**For a Business Owner:** Khalid's accountant presents a trial balance that doesn't balance. The difference is AED 18,000. Khalid asks what went wrong. His accountant explains: AED 18,000 is divisible by 9, which suggests a transposition error. They check and find that a AED 81,000 cash receipt was recorded as AED 18,000 — digits were transposed. --- **For a Junior Accountant:** Fatima's trial balance shows debits of AED 950,000 and credits of AED 945,000 — a AED 5,000 difference. She tries dividing by 2: AED 2,500 — not a likely wrong-side error. She tries dividing by 9: AED 555.56 — not divisible, not a transposition. She checks for round numbers: AED 5,000 is round — likely a one-sided posting. She reviews the journal and finds a AED 5,000 rent payment that was debited to rent expense but never credited to cash. She posts the credit, and the trial balance balances.

Key takeaways

  • A trial balance lists all account balances and verifies that total debits equal total credits.
  • If the trial balance doesn't balance, a posting error has occurred.
  • Dividing the difference by 2 may indicate a balance on the wrong side; by 9 may indicate a transposition error.
  • Errors are corrected with journal entries after they are located.
