What reconciliation means and why you do it

Reconciliation is the process of comparing your bank statement with your own records to make sure the numbers match. You are checking that the balance the bank shows is the same as the balance you show in your checkbook or banking app.

The reason you do this is straightforward: mistakes happen. The bank might record a deposit wrong. You might forget you wrote a check. A payment you thought went through might still be pending. Reconciliation catches these problems before they cause overdrafts or leave you thinking you have money you do not actually have.

Most people reconcile once a month, when their bank statement arrives. If you bank online, you can do it more often — some people reconcile weekly. The process takes 15 to 30 minutes if you stay organized.

Key Takeaways

  • Reconciliation means comparing your records to your bank statement to find differences and fix them.
  • You need your current bank statement, your checkbook or transaction list, and a pen and paper or a spreadsheet.
  • The basic steps are: list what the bank shows, list what you show, find the difference, and figure out why it exists.
  • Most differences are caused by checks or transfers that have not cleared yet, or by deposits the bank has not processed.
  • If you cannot find the difference after checking twice, contact your bank with the specific amount and date.

Gather what you need before you start

Pull together three things: your most recent bank statement (the paper one or the one you read from your online banking), your checkbook or a list of all the transactions you have made since the last statement, and a piece of paper or a spreadsheet where you can write things down.

If you use online banking, you can usually read a statement as a PDF or view it directly in your account. If you still receive paper statements in the mail, use that. The statement will show the opening balance (what you started with), all the deposits and withdrawals the bank processed, and the closing balance (what the bank says you have now).

Your checkbook or transaction list should include every check you wrote, every transfer you made, every deposit you put in, and every withdrawal you took out. If you use a banking app, you can usually see this list right there. If you write checks by hand, your checkbook register is your list.

List the checks and transfers that have not cleared

Go through your checkbook or transaction list and find every check you wrote and every transfer you sent that does not appear on the bank statement. These are called outstanding items — they are money you told the bank to send, but the bank has not processed them yet.

Write down the check number and amount for each one. Do the same for any transfers you made to another account or to another person that the statement does not show. Add up all these amounts. This is your "outstanding total."

It is normal for checks to take three to five business days to clear, especially if you mailed them. Transfers between accounts at the same bank usually clear the same day or the next day. If something has been outstanding for more than a week, you might want to follow up with the recipient or your bank.

Do the math to find the difference

Start with the closing balance on your bank statement — the number the bank says you have. Subtract your outstanding total (the checks and transfers that have not cleared yet). This number should match the balance in your checkbook.

Here is an example: Your bank statement says you have $1,200. You have two outstanding checks: one for $50 and one for $75. That is $125 total. $1,200 minus $125 equals $1,075. If your checkbook says $1,075, you are reconciled.

If the numbers do not match, the difference is what you are looking for. Write down the exact amount of the difference. Is it $10? $100? $0.50? The size of the difference often tells you what went wrong.

Find what caused the mismatch

If your checkbook balance is higher than the bank statement, you probably missed recording a withdrawal or fee. Look at the bank statement line by line and check off each item in your checkbook as you see it. Anything on the statement that is not checked off in your book is the problem.

Common things people miss: ATM fees (usually $2 to $3), monthly account maintenance fees, overdraft fees, or automatic payments that come out on a set date each month. Banks also sometimes charge fees for things like wire transfers or returned checks.

If your checkbook balance is lower than the bank statement, you probably recorded a deposit that has not cleared yet, or you forgot to write down a deposit someone sent you. Go through the deposits on the statement and make sure each one is in your checkbook.

If the difference is a small amount like $0.01 or $0.50, it might be a rounding error or a bank processing fee. If it is a large amount and you cannot find it, stop and contact your bank before you spend any money.

Update your checkbook and keep it current

Once you find what caused the mismatch, write it down in your checkbook. If you missed recording a fee, add it as a withdrawal. If you missed recording a deposit, add it as a deposit. Recalculate your balance. Now your checkbook should match the bank statement (minus the outstanding checks and transfers).

Going forward, the easiest way to avoid reconciliation problems is to record every transaction the day you make it. If you use a debit card, write it down or log into your app right away. If you use online bill pay, record the payment when you schedule it, not when it clears. If someone sends you money, record it as soon as you see it in your account.

Many people find it easier to reconcile more often — every week or every two weeks — rather than waiting a month. Smaller time windows mean fewer transactions to track and smaller differences to hunt for.

What to do if you cannot find the problem

If you have checked twice and the numbers still do not match, contact your bank. Have your statement and your checkbook in front of you. Tell them the exact amount of the difference and the date range you are looking at. They can look at the actual transactions that cleared and help you find what went wrong.

Banks are used to these calls and can usually find the problem in a few minutes. They might tell you that a check you thought cleared actually bounced, or that a deposit you thought went through was rejected, or that a fee was applied that you did not know about. Once you know what happened, you can update your checkbook and move forward.

Do not assume the bank is always right. Banks make mistakes too. If you believe the bank recorded something wrong, ask them to investigate and provide proof. Most banks will reverse a fee if you can show it was their error.

Frequently Asked Questions

How often should I reconcile my account?

Most people reconcile once a month when their statement arrives, but you can do it more often if you want to stay on top of your balance. Some people reconcile weekly. The more often you do it, the easier it is because there are fewer transactions to track.

What if a check I wrote six months ago still has not cleared?

A check that old is considered stale. Most banks will not cash a check that is more than six months old, though they are not required to refuse it. Contact the person you wrote the check to and ask if they ever received it. If they did not, you can write a new one. If they did but never cashed it, ask them to destroy it.

Do I need to reconcile if I use online banking and check my balance every day?

Checking your balance daily is helpful, but it is not the same as reconciliation. Your daily balance shows what the bank has processed so far, but it does not show pending transactions or help you catch bank errors. A full reconciliation once a month is still a good idea.

What does "pending" mean on my bank statement?

Pending means the bank has seen the transaction but has not finished processing it yet. Pending transactions will usually clear within one to three business days. Do not spend money based on pending deposits — only count cleared money as available.

Can the bank make a mistake during reconciliation?

Yes. Banks process thousands of transactions daily and errors do happen — a deposit recorded twice, a withdrawal recorded to the wrong account, or a fee applied by mistake. If you find a discrepancy the bank cannot explain, ask them to investigate and provide documentation of the transaction.
