How to Reconcile a Bank Statement, Step by Step
Reconciliation explains every difference between the bank’s period-end balance and your own records.
1. Gather records for the same cutoff date
Use the issued bank statement and your cash ledger, check register, or accounting report for the identical period end. Keep deposit records, payment confirmations, and prior reconciliation nearby. Starting with different cutoff dates creates false differences before the work begins.
Confirm that the prior period’s adjusted balance became this period’s starting point. An unresolved difference carried forward is easier to find before hundreds of new transactions are introduced.
2. Match activity and classify every difference
Match deposits, electronic receipts, checks, card transactions, transfers, withdrawals, fees, and interest. Use amount, date, reference, and description together; identical amounts can be unrelated. Mark each match in both sources so unmatched items remain visible.
Most remaining items fall into three groups: timing differences, items present only at the bank, or errors. Outstanding checks and deposits in transit are timing differences. Bank fees or interest may require book entries. Duplicate, omitted, or incorrectly recorded amounts require correction in the system where the error occurred.
- Outstanding payment: recorded in books, not yet posted by the bank.
- Deposit in transit: recorded in books, not yet included by the bank.
- Bank-only item: fee, interest, returned payment, or automatic transfer not yet in books.
- Error: wrong amount, duplicate, omission, or unauthorized activity that needs investigation.
3. Calculate adjusted balances and document the result
On the bank side, start with the statement ending balance, add deposits in transit, and subtract outstanding payments. On the book side, start with the ledger balance and record bank-only items and corrections. The two adjusted balances should agree exactly.
Save the reconciliation, the list of outstanding items, and evidence for corrections. Investigate stale outstanding checks rather than rolling them forever. If you discover an unauthorized electronic transaction, notify the institution promptly; the CFPB describes important notice windows tied to the statement date.

Frequently asked questions
What if the adjusted balances do not match?+
Check transposed digits, duplicated or omitted items, sign errors, wrong cutoff dates, and the prior reconciliation. Divide the difference by nine to spot some transpositions, but still trace the actual transaction before correcting it.
How often should bank accounts be reconciled?+
At least each statement period, and more often for high-volume or high-risk accounts. Frequent matching reduces the number of transactions involved when a difference appears.
