Ledger in plain English

The journal lists transactions in date order. The ledger re-sorts them by account, so you can see everything that happened to Cash, or to Rent, in one place and read its balance.

Worked example

The owner invests 10,000 and the business buys equipment for 2,000 in cash. The Cash account in the ledger looks like this:

Cash account
DebitCredit
Capital 10,000Equipment 2,000
Balance carried down 8,000
10,00010,000

The Cash account has a debit balance of 8,000.

Common mistakes
  • Posting to the wrong side of an account.
  • Posting only one half of an entry, which makes the trial balance fail.
