How to Reconcile Your Bank Statement: A Step-by-Step Guide
February 25, 2026
Why Bank Reconciliation Matters
Bank reconciliation — comparing your internal records against your bank statement — is the fundamental accounting control that catches fraud, identifies errors, and confirms your books are accurate. Without it, errors compound over time until a small discrepancy becomes a significant financial problem.
For individuals: reconcile monthly to catch unauthorized charges, bank errors, and math mistakes. For businesses: reconcile monthly at minimum, weekly for high-volume accounts.
Before You Start: Gather Your Materials
- Your bank statement (the official statement from your bank, not your online balance)
- Your internal records: check register, accounting software ledger, or spreadsheet
- Outstanding checks from last month (checks written but not yet cleared)
- Deposits in transit from last month (deposits recorded but not yet on the statement)
The Reconciliation Process
Step 1: Match Deposits
Go through every deposit on your bank statement and check it off against your records. Mark both sides — confirm the amount and date match. Note any deposits on your statement that aren't in your records (bank interest, credits you missed) and any deposits in your records that aren't on the statement yet (deposits in transit).
Step 2: Match Payments and Withdrawals
Go through every debit on the statement: checks cleared, ACH payments, debit card transactions, bank fees. Match each to your internal records. Check off matched items on both sides.
Note unmatched items in each category:
- On statement but not in records → bank charges you missed, errors to investigate
- In records but not on statement → outstanding checks, payments not yet processed
Step 3: Adjust the Bank Balance
Start with the ending balance on your bank statement.
+ Deposits in transit (recorded in your books, not yet on statement)
− Outstanding checks (written in your records, not yet cleared)
= Adjusted bank balance
Step 4: Adjust Your Book Balance
Start with the ending balance in your records (accounting software or register).
+ Bank credits not yet recorded (interest earned, refunds received)
− Bank charges not yet recorded (monthly fees, NSF fees, wire fees)
− Errors in your records (corrected after identification)
= Adjusted book balance
Step 5: Compare
Adjusted bank balance should equal adjusted book balance. If they match: reconciliation is complete. If they don't match: there's an error somewhere to find.
Finding Reconciliation Discrepancies
Common causes of discrepancies:
- Transposition error: $8,246 recorded as $8,264 — difference divisible by 9 (try dividing the discrepancy by 9 to identify transpositions)
- Missing transaction: A charge was made but never recorded
- Duplicate recording: Same transaction entered twice in your books
- Wrong amount: Transaction recorded at wrong amount
- Bank error: Rare but it happens — a charge applied to wrong account, incorrect fee
Automating the Data Entry Side
The most tedious part of reconciliation is getting transaction data into a format you can work with. For PDF bank statements, manual transcription is error-prone and time-consuming.
