What is the purpose of a trial balance?

• A. To prepare the income statement
• B. To show only asset balances
• C. To ensure total debits equal total credits in the ledger and to detect errors.
• D. To record adjusting entries

Answer: (C)

The main purpose of a trial balance is to verify the accounting equation’s arithmetic: the total of all debit balances should equal the total of all credit balances in the ledger. This balance serves as a check that postings were made correctly and that sum totals are accurate, helping to catch errors in recording or totaling before moving on to financial statements.

It’s a stepping stone, not the final report. The trial balance itself isn’t used to prepare the income statement directly, and it isn’t a record of adjusting entries. It also includes all accounts, not just assets, giving a complete picture of the ledger’s state. However, even when the totals match, some errors can still exist (such as a wrong amount posted to the right side or a misclassification that offset each other), so it’s a diagnostic tool rather than a guarantee of perfect books.
