How to Make an Unadjusted Trial Balance

The unadjusted trial balance is a foundational internal document in the accounting cycle, summarizing all general ledger account balances at a specific point in time. Its primary function is to verify the mathematical equality of total debits and total credits following the double-entry bookkeeping system. This preliminary report helps identify potential errors in recording transactions before financial statements are prepared. Businesses use this report to gain a high-level overview of their financial accounts, ensuring the fundamental accounting equation (Assets = Liabilities + Equity) remains in balance.

This document is typically generated after all daily transactions for an accounting period have been journalized and posted to the general ledger, but before any adjusting entries are made. While it confirms numerical balance, it does not guarantee that all transactions were recorded correctly or that no other errors exist.

Gathering the Necessary Data

The process of preparing an unadjusted trial balance begins with extracting information from the general ledger, the complete record of all financial transactions for a business. Each general ledger account, such as cash or accounts payable, maintains a running balance of its debits and credits. Identify all active accounts with a non-zero balance at the end of the accounting period.

For each active account, determine its current balance. In a manual system, this involves “balancing off” each ledger account by summing debits and credits and calculating the difference. Modern accounting software typically generates this information automatically through a “Chart of Accounts” or a “General Ledger” report.

Correctly identifying whether each account’s balance is a debit or credit is important. Assets and expenses typically carry normal debit balances, meaning an increase is recorded as a debit. Conversely, liabilities, equity, and revenues typically carry normal credit balances, meaning an increase is recorded as a credit.

Understanding the normal balance of each account type is important for correctly placing figures on the unadjusted trial balance. For example, a Cash account usually has a debit balance, while a Sales Revenue account generally has a credit balance. An account showing a balance opposite to its normal type might indicate an error in recording transactions, such as an overpayment or a misplaced entry.

Constructing the Unadjusted Trial Balance

Once all necessary account data and balances have been gathered from the general ledger, arrange this information into the unadjusted trial balance format. This document typically features three columns: account name, debit balances, and credit balances. Accounts are usually listed in a standardized order, beginning with assets, followed by liabilities, equity, revenues, and finally expenses, mirroring the structure of financial statements.

To populate the unadjusted trial balance, list each general ledger account, usually accompanied by its account number. For every account, its ending balance is then transferred to either the debit column or the credit column, based on its normal balance type. For instance, the final balance of the Cash account, which normally has a debit balance, would be entered in the debit column. Similarly, the balance of an Accounts Payable account, typically a credit balance, would be recorded in the credit column.

After all active accounts and their balances have been entered, sum the individual amounts in the debit column to arrive at a total debit figure. Concurrently, sum the amounts in the credit column to produce a total credit figure.

The format often includes a clear heading with the company’s name, the title “Unadjusted Trial Balance,” and the specific date for which the balances are reported. Monetary amounts are typically indicated with a dollar sign at the top of each column and for the final totals. The final totals for both the debit and credit columns are presented at the bottom, often double-underscored to signify completion.

Verifying Accuracy

The final step after constructing the unadjusted trial balance is to verify its accuracy. The fundamental principle of double-entry accounting dictates that for every debit entry there must be a corresponding credit entry, meaning the total of all debit balances must precisely equal the total of all credit balances on the trial balance. This equality serves as an initial mathematical check of the accounting records.

The verification process involves comparing the grand total of the debit column with the grand total of the credit column. If these two totals match, the unadjusted trial balance is considered “in balance.” This balance indicates that the mathematical computations involved in journalizing transactions and posting them to the general ledger have been performed without certain types of arithmetic errors.

However, if the total debits do not equal the total credits, the trial balance is “unbalanced,” signaling that an error exists somewhere in the accounting records. An imbalance means that a transaction was likely recorded incorrectly, perhaps by posting an amount to the wrong side of an account, transposing digits, or omitting an entry. While a balanced trial balance confirms numerical accuracy, it does not detect all types of accounting errors, such as a transaction being entirely unrecorded, or a correct amount being posted to the wrong account.

Should an imbalance occur, it necessitates a systematic review of the financial records to locate and correct the discrepancy. This might involve re-totaling columns, verifying individual account balances, or tracing transactions back to their original journal entries.
