How to Read Your Bank Statement and Spot Errors

Why Reading Your Bank Statement Matters

Many business owners glance at their bank balance periodically but never actually sit down to read their bank statement from top to bottom. This is a missed opportunity. Your bank statement is a complete, authoritative record of every pound that came into and went out of your account during a period. Reading it carefully - not just checking the balance - is how you catch bank errors, spot fraudulent transactions, identify duplicate charges, notice subscriptions you forgot to cancel, and verify that all expected payments arrived. It's also a key input to your bank reconciliation process.

The Structure of a Bank Statement

Most bank statements follow the same basic structure:

Opening balance: The account balance at the start of the statement period. This should match the closing balance of your previous statement.
Transactions: A chronological list of every debit (money out) and credit (money in) during the period, with the date, a description or reference, and the amount.
Closing balance: The account balance at the end of the statement period. This equals opening balance plus all credits minus all debits.
Summary: Some statements include a summary of total credits and debits for the period - useful for a quick overview of transaction volume.

Debits vs. Credits on a Bank Statement

One source of confusion: the terminology on bank statements is from the bank's perspective, not yours. A "credit" on your bank statement means money coming in to your account (the bank owes you more). A "debit" means money going out (you have less with the bank). This is the opposite of how debits and credits work in accounting - where a debit increases an asset account and a credit decreases it. Don't let this confuse you: on a bank statement, credit = money in, debit = money out.

What to Look for When Reviewing Your Statement

Go through your statement line by line each month with these checks in mind:

Unexpected debits: Any payment you don't recognise or didn't authorise. These could be fraud, a cancelled subscription that's still charging, or a bank error.
Duplicate transactions: The same payment appearing twice in the same period. Can happen with manual bank transfers or processing errors.
Incorrect amounts: A payment for a different amount than expected - either you were overcharged or undercharged.
Missing credits: An expected payment from a client or other source that should have arrived but hasn't.
Bank charges: Any fees charged by the bank - are they correct per your account agreement? Unexpected fee increases should be queried.
Standing orders and direct debits: Confirm all regular payments are for the correct amounts and are payments you've authorised.

When to Query a Transaction

If you see a transaction you don't recognise or believe is incorrect, contact your bank promptly. For potential fraudulent transactions, most banks have a 13-month window to raise a dispute - but reporting sooner dramatically increases the chances of recovery. For billing disputes with suppliers or service providers, contact the supplier directly first; if they don't resolve it, your bank can initiate a chargeback on card payments. Document everything: take a screenshot of the transaction and note the date, amount, and what action you took.

Bank Statements as a Bookkeeping Tool

Your bank statement is the authoritative source of truth for your cash transactions. Any expense or income in your books that doesn't have a corresponding entry on your bank statement needs to be explained. Any bank statement entry not in your books needs to be recorded. This comparison - statement to books - is bank reconciliation, and it's how you confirm your accounts are accurate.
