A bank statement is a record of every transaction that moved money in or out of your account during a set period, usually one month

Your bank creates this document to show you what happened to your money. It lists deposits (money coming in), withdrawals (money going out), transfers between your accounts, fees the bank charged, and interest earned. The statement covers a specific date range — typically the first through the last day of a calendar month, though some banks use different cycles.

Banks send statements either by mail or email, depending on what you chose when you opened the account. You can also log into your online banking and read or view statements whenever you need them, usually going back several years. The statement shows your opening balance on the first day, your closing balance on the last day, and every single transaction in between.

Key Takeaways

  • A bank statement lists every deposit, withdrawal, transfer, and fee for one month, with dates and amounts for each transaction.
  • The opening balance shows what was in your account on the first day of the period; the closing balance shows what remains on the last day.
  • You can receive statements by mail or email, and you can read past statements from your online banking portal for several years back.
  • Banks use statements to help you catch fraud, verify your income for loans or housing, and track where your money went.

The parts of a statement and what each one means

Every statement has a header with your name, account number, and the date range it covers. Below that is your opening balance — the amount in the account on day one of the period. Then comes a list of transactions in order by date.

Each transaction line shows the date it posted (when the bank recorded it), a description of what happened (like "Debit Card Purchase at Grocery Store" or "Direct Deposit from Employer"), and the amount. Deposits appear as additions; withdrawals and payments appear as subtractions. At the bottom is your closing balance — what you have left after all transactions and fees.

Some statements also show pending transactions separately, because a transaction you made today might not post to the account for one or two business days. Your available balance (what you can spend right now) may differ from your account balance (what the statement shows) because of these pending items.

Why you need to keep statements

A bank statement is proof that money moved. Landlords ask for statements to verify you have income and can pay rent. Lenders want statements to see your spending habits and confirm you have savings. Courts use statements in divorce or custody cases. The IRS may ask for statements if you report self-employment income.

Statements also protect you. If someone uses your debit card without permission or a fraudulent transfer leaves your account, the statement is your record of what happened. You have a limited window — usually 30 to 60 days — to report fraud to your bank, and the statement is what proves the unauthorized transaction occurred.

Keep statements for at least one year, and longer if you own a business, are in a legal dispute, or claim deductions on your taxes. Many people keep them for seven years to match IRS record-keeping rules.

How statements differ between account types

A checking account statement shows every check you wrote, every debit card purchase, every transfer out, and every deposit in. It typically includes monthly fees and overdraft charges if you spent more than you had.

A savings account statement shows deposits, withdrawals, and interest earned each month. The interest line is important because it tells you how much the bank paid you for keeping money there. Some savings accounts have limits on how many withdrawals you can make per month, and the statement will show if you exceeded that limit and were charged a fee.

A money market account statement looks similar to a savings statement but may show check-writing activity if your account includes that feature. A certificate of deposit (CD) statement shows the deposit amount, the interest rate, the maturity date, and the interest paid when the CD reaches its end date.

The difference between posting date and transaction date

The transaction date is when you made the purchase or initiated the transfer. The posting date is when the bank actually recorded it and the money left (or arrived in) your account. These are often different, which confuses people.

If you swipe your debit card on Tuesday, the transaction date is Tuesday, but it might not post until Thursday. During those two days, the money is still in your account — your available balance reflects the pending charge, but your account balance on the statement shows the full amount until Thursday arrives. Once it posts, the statement is updated and the money is gone.

This matters because you can overdraft your account based on pending transactions that haven't posted yet. If you have $500 and make a $400 purchase that's pending, you might think you have $500 to spend, but your available balance is $100. Spending that $100 could cause an overdraft when the $400 transaction posts.

Reading the transaction description line

The description tells you what kind of transaction it was, but the wording varies by merchant and bank. A grocery store purchase might say "POS Purchase at Safeway" (POS means point of sale). An online purchase might say "Amazon.com" or "Amzn Marketplace." A transfer between your own accounts might say "Transfer to Savings" or "Internal Transfer."

Direct deposits from employers usually show the employer name or a payroll company name. Automatic bill payments show the company name — "Electric Company" or "Mortgage Servicer." ATM withdrawals show the location or just "ATM Withdrawal." If the description is vague or you don't recognize it, that's a sign to investigate, because it could be fraud.

Some merchants use abbreviations or shortened names that don't match what you remember. A restaurant might appear as "REST" or a gas station as "SHELL" or "CHEVRON." If you're unsure what a transaction is, check your receipts or credit card records to match them up.

How to spot errors or fraud on your statement

Read your statement as soon as you receive it. Look for transactions you don't remember making, amounts that don't match what you expected, or duplicate charges (the same transaction appearing twice). Check that deposits match your pay stubs or other records.

If you find an error, contact your bank when ready. For unauthorized transactions (fraud), you have stronger legal protection if you report it within 60 days. For other errors — a deposit that didn't post, a charge that's wrong — banks typically investigate within 10 business days.

Keep receipts from your purchases and match them to the statement. If a receipt says $25 but the statement shows $35, that's a discrepancy worth investigating. If you made a transfer and the amount is different from what you intended, report it right away.

Frequently Asked Questions

How long does a bank keep statements available?

Most banks keep statements available online for at least seven years, though some go back further. Paper statements sent by mail are your responsibility to keep. If you need a statement older than what's available online, contact your bank — they can usually retrieve archived statements for a fee or sometimes at no charge.

Can I use a bank statement to prove my income?

Yes. Landlords, lenders, and government programs often accept bank statements as proof of income, especially if you're self-employed or receive irregular payments. They want to see deposits from your employer or clients over several months. Bring statements from the last two or three months to show a pattern of income.

What if my statement shows a transaction I didn't make?

Report it to your bank when ready, either by phone or through your online banking portal. The bank will investigate and, if the transaction was truly unauthorized, will refund the money. You have stronger legal protection if you report it within 60 days, though you can report it later.

Do I need to keep paper statements or is digital enough?

Digital is enough if you can read and save the statements to your computer or cloud storage. Print or save a copy of important statements (ones showing large deposits, loan payments, or tax-related transactions) in case you need them later. Keep at least one year of statements easily accessible.

Why does my available balance differ from my account balance?

Available balance accounts for pending transactions — charges you made that haven't posted yet. Your account balance is what the statement shows; your available balance is what you can actually spend right now. The difference closes once pending transactions post, usually within one to two business days.
