How to Read a Bank Statement

A bank statement is an itemised record of everything that entered and left your account over a period, usually a month. Every statement has the same four parts: a header, an opening balance, a transaction list, and a closing balance.

The header of a bank statement

The top of the statement identifies whose money and which period you are looking at:

Your name and address, and the bank's details
Account number (often partly masked) and account type
Statement period, e.g. "1 June to 30 June"

Always check the period first; a transaction you are looking for may simply be on the next statement.

Opening balance, closing balance, running balance

Opening balance: what the account held at the start of the period. It always equals the previous statement's closing balance.
Running balance: the balance after each individual transaction, shown as the last column of the transaction list. If a line looks wrong, the running balance shows exactly where the numbers diverged.
Closing balance: the result after all listed transactions: opening balance + money in − money out.

Debit and credit columns

On a bank statement, debit and credit are from the bank's perspective, which surprises people:

Debit = money leaving your account: purchases, bill payments, withdrawals, fees.
Credit = money entering: salary, transfers in, refunds.

Some statements use one signed amount column instead: negative for money out, positive for money in. Credit card statements flip the convention, where purchases appear as positive charges.

Each statement transaction line

A transaction line has a date, a description, and an amount. Descriptions are written by merchants and processors, so they can be cryptic:

"SQ *" or "PAYPAL *" prefixes: the payment processor, followed by the actual seller.
Abbreviations: "AMZN MKTP" is Amazon Marketplace, "WMT" is Walmart.
"TRIPS" or similar odd words: often a merchant's internal billing name; search the exact text plus "charge" to identify it.
Debit interest: interest the bank charged you for a negative (overdrawn) balance during the period.
Pending vs posted: statements show only posted transactions; a pending card hold may post later with a different amount.

A 2-minute monthly review

1. Verify the opening balance matches last month's closing balance.

2. Scan for unfamiliar descriptions and identify each one; unrecognized charges are how card fraud is usually caught.

3. Note the fees and interest lines; they are the easiest costs to eliminate.

To go from reading to analyzing, upload the statement and let categories show where the money went.
