The trial balance

ZIMSEC O Level · Principles of Accounts · Form 3

A trial balance lists all ledger balances at a date in two columns. If double entry is correct, the totals agree.

Debit and credit balances

  • Debit: assets, expenses, drawings, purchases, sales returns.
  • Credit: capital, liabilities, sales, purchases returns, income (e.g. rent received, discount received).

Worked example: Prepare a trial balance from: Capital 10 000; Equipment 6 000; Bank 3 500; Purchases 4 000; Sales 7 000; Wages 1 500; Payables 1 200; Receivables 3 200.

Debits: Equipment 6 000 + Bank 3 500 + Purchases 4 000 + Wages 1 500 + Receivables 3 200 = 18 200

Credits: Capital 10 000 + Sales 7 000 + Payables 1 200 = 18 200

Errors the trial balance does not show

  • Omission (left out completely), commission (wrong person's account), principle (wrong class of account), original entry (wrong amount in both), complete reversal, compensating errors.
Exam tip: Agreement of the trial balance does not prove the books are free of errors.

Check yourself
