Bank Reconciliation

What is Bank Reconciliation?

Bank Reconciliation is a critical accounting process that compares the bank balance on a bank statement with the corresponding balance recorded in a company's internal cash book (ledger) on a specific date. The goal is to identify discrepancies and make adjustments to ensure the internal records and the bank's records match.

Reconciliation is necessary because there is almost always a time lag between when transaction records are created internally and when they are cleared by the bank. Running regular reconciliations helps detect unauthorized transactions, double charges, bank errors, and internal bookkeeping mistakes, preventing cash flow issues.

The Bank Reconciliation Process

Reconciling your bank statement involves adjusting both the bank statement ending balance and your internal cash book balance. After all adjustments are applied, the two adjusted balances must be equal.

1. Adjusting the Bank Statement Balance

You must adjust the bank's ending balance for items that the bank does not know about yet, or for errors made by the bank:

\[ \text{Adjusted Bank Balance} = \text{Bank Balance} + \text{Deposits in Transit} - \text{Outstanding Checks} \pm \text{Bank Errors} \]

• Deposits in Transit: Cash or checks received and recorded in your books, but not yet shown on the bank statement.
• Outstanding Checks: Checks written and recorded in your books, but not yet presented to or cleared by the bank.

2. Adjusting the Cash Book Balance

You must adjust your internal cash book balance for transactions that appear on the bank statement but have not yet been recorded in your books:

\[ \text{Adjusted Cash Book} = \text{Book Balance} + \text{Interest Earned} - \text{Bank Fees} - \text{NSF Checks} \pm \text{Bookkeeping Errors} \]

• Interest Earned: Interest paid by the bank to your account.
• Bank Fees: Monthly service charges, check printing fees, or overdraft fees.
• NSF (Non-Sufficient Funds) Checks: Checks deposited from customers that bounced due to lack of funds. Since they were initially added to your balance, they must now be deducted.
