A bank reconciliation statement is a statement that reconciles the bank balance as per the cash book with the bank balance as per the bank statement. It helps to identify any discrepancies or differences between the two balances and provides an explanation for those differences.

The main purpose of preparing a bank reconciliation statement is to identify the causes of the difference between the cash book and the bank statement. These differences may arise due to various reasons, such as:

- **Timing Differences:** Transactions recorded in the cash book may not have been processed by the bank at the time of preparing the bank statement. This can lead to differences in the balances.

- **Bank Charges and Interest:** Bank charges or interest earned on the bank account may not have been recorded in the cash book. These differences need to be identified and adjusted.
