The trial balance

🎬 The doodle video for this lesson is coming soon. Subscribe on YouTube to see it first.

A trial balance lists all the ledger balances to check that total debits equal total credits.

Purpose

A trial balance lists every ledger account balance at a date, in a debit or credit column.
It checks the arithmetical accuracy of the double entry: total debits should equal total credits.
It is also the starting point for preparing the financial statements.

Which side?

Limitations

A trial balance that balances does not prove the books are correct.
Some errors do not affect the totals, such as missing a transaction completely (omission), posting to the wrong customer (commission) or posting to the wrong type of account (principle).
Worked example

Debit balances total £84 500. Credit balances are capital £50 000, sales £30 000 and payables £4500. Does it balance?

  1. Credits = 50 000 + 30 000 + 4500 = £84 500
  2. Debits = £84 500

Answer: Yes, both total £84 500

Key idea

A trial balance lists ledger balances to check debits equal credits and to help prepare financial statements. Assets, expenses and drawings are debits; liabilities, capital and income are credits. It does not reveal every error.
