Bank reconciliation in plain English

Your cash book and your bank statement rarely match on a given day. Some payments you recorded have not cleared yet, and the bank may have added charges you have not recorded. Reconciling finds and explains each difference.

Worked example

The cash book shows 5,000. The bank charged 50 in fees that are not yet in the cash book. There are cheques written for 600 not yet presented to the bank, and deposits of 900 that the bank has not yet credited.

Step 1: update the cash book. 5,000 − 50 bank charge = 4,950.

Common mistakes
  • Forgetting to update the cash book first for items the bank has recorded, such as charges and direct debits.
  • Adjusting the wrong way. Unpresented cheques are subtracted from the bank statement balance.
