How to Reconcile Your Bank Statements (Step by Step)

What Is Bank Reconciliation?

Bank reconciliation is the process of comparing your internal financial records against your bank statement to make sure they match. If they do not match, you investigate the differences and make corrections. This is one of the most important tasks in bookkeeping because it catches errors, detects fraud, and ensures your financial reports are trustworthy.

Why You Must Reconcile Every Month

Errors happen. Banks make mistakes, transactions get entered twice, or payments get recorded in the wrong amount. Without reconciliation, these issues accumulate silently. By the time you discover them, untangling the mess can take days.

Regular reconciliation also protects you from unauthorized transactions. If someone gains access to your account, you will catch fraudulent charges quickly rather than months later.

Step-by-Step Reconciliation Process

Step 1: Gather Your Documents

Pull your bank statement for the period (usually monthly) and open your bookkeeping records for the same period. You need both side by side. If you are unsure how to read your bank statement, start there first.

Step 2: Compare the Ending Balances

Check whether your book balance matches the bank statement ending balance. They will rarely match exactly at first, and that is normal. The goal of reconciliation is to explain every difference.

Step 3: Identify Outstanding Items

Common differences include:

Outstanding checks -- checks you have written that have not cleared the bank yet
Deposits in transit -- money you have deposited that has not appeared on the statement
Bank fees -- service charges, wire fees, or overdraft fees you have not recorded
Interest earned -- bank interest that has not been entered in your books
Errors -- data entry mistakes in either your books or the bank records

Step 4: Adjust Your Books

For each difference you identified, make the necessary journal entries. Add any bank fees or interest you missed. Correct any amounts that were entered incorrectly. Remove any duplicate entries.

Step 5: Verify the Adjusted Balance Matches

After making all adjustments, your adjusted book balance should equal the adjusted bank balance. If it does not, go back and check for items you may have missed.

Your Books	Bank Statement
Starting book balance	Starting bank balance
+ Bank interest earned	+ Deposits in transit
- Bank fees not recorded	- Outstanding checks
+/- Error corrections	+/- Error corrections
= Adjusted book balance	= Adjusted bank balance

Time Saver: Finntree automates much of the reconciliation process by importing transactions directly from your bank and highlighting discrepancies so you only need to review exceptions rather than every line item.

How Often Should You Reconcile?

Monthly is the minimum. High-volume businesses may benefit from weekly reconciliation. The more frequently you reconcile, the fewer discrepancies you will find each time, and the faster the process becomes.
