The last step is confirming that your calculated balance matches your bank's balance
After you have subtracted outstanding checks and added deposits in transit, you arrive at a number. Your bank statement arrives at a different number. The final step in reconciliation is comparing these two numbers—your adjusted balance and the bank's adjusted balance—and confirming they match. If they do, reconciliation is complete. If they do not, you have found an error that needs investigation.
This step takes minutes if your math was correct. It takes longer if a transaction is missing, duplicated, or recorded at the wrong amount. The point of reaching this final step is that you now know exactly where the discrepancy lives: in your records, in the bank's records, or in neither (a timing issue that will resolve on its own).
Key Takeaways
- The final step compares your adjusted checkbook balance to the bank's adjusted statement balance; they must match exactly.
- If the two numbers do not match after adjustment, the error is in a specific transaction—either one you recorded wrong, one the bank recorded wrong, or one that has not cleared yet.
- A mismatch of a few cents usually points to a math error in your adjustments; a mismatch of dollars usually points to a missing or duplicated transaction.
- Once the two adjusted balances match, your reconciliation is finished and your account is accurate as of that statement date.
How to compare the two adjusted balances
You have two numbers in front of you. The first is your checkbook balance after you have added back deposits in transit and subtracted outstanding checks. The second is your bank statement balance after the bank has made the same adjustments. Write both numbers down clearly so you can see them side by side.
If they are identical, you are done. Write the date and the final balance in your checkbook or reconciliation record. Your account is reconciled as of that statement closing date.
If they differ, subtract the smaller from the larger to find the gap. A difference of $0.01 or $0.02 usually means you made an arithmetic error when adding or subtracting in the previous steps. A difference of $10, $50, or more usually means a transaction is missing from one side or the other, or was recorded at the wrong amount.
Finding the error when balances do not match
Start by checking your math. Add up all the deposits in transit again. Add up all the outstanding checks again. Recalculate your adjusted balance. Many reconciliation failures stop here—the error was a keystroke or an addition mistake, not a missing transaction.
If your math is correct, look for a transaction that appears on one statement but not the other. Compare your checkbook line by line against the bank statement. Check the amounts, the dates, and the payees. A check you wrote for $45 that the bank cleared for $54 will create a $9 gap. A deposit you recorded as $200 that actually posted as $2,000 will create a $1,800 gap.
If you find a transaction that is on the bank statement but not in your checkbook, add it to your records and recalculate. If you find a transaction in your checkbook that is not on the bank statement, check whether it is truly outstanding (not yet cleared) or whether it was never sent or deposited. A check you wrote three months ago that still has not cleared is unusual and worth investigating with the recipient or the bank.
When the bank's records are wrong
Occasionally the error is on the bank's side. A deposit might be recorded twice. A check might clear for the wrong amount. A fee might be charged in error. If you have found a transaction that the bank recorded incorrectly, contact the bank with the evidence: your deposit receipt, a photo of the check, a screenshot of the transfer confirmation.
The bank will investigate and either correct the error or explain why the transaction posted as it did. This process usually takes three to five business days. Until it is resolved, you will not be able to complete reconciliation—your balance and the bank's balance will not match because one of them is wrong. Once the bank corrects the error, you can finish reconciliation.
Timing issues that resolve on their own
Some discrepancies are not errors at all. A check you mailed last week might not have cleared yet. A mobile deposit you made yesterday might not have posted. A transfer you initiated might still be in process. These are timing issues, not mistakes.
If you have accounted for all outstanding checks and deposits in transit, and the two adjusted balances still do not match, the missing transaction is probably still moving through the system. Wait a few business days and reconcile again. The transaction will appear on the next statement, and the balances will match.
Recording the reconciliation when it is complete
Once your adjusted balance matches the bank's adjusted balance, write down the final balance and the statement closing date in your checkbook or reconciliation worksheet. Some people also note the date they completed the reconciliation. This record shows that you have verified your account as of that date and that everything was accurate at that moment.
Keep the bank statement and your reconciliation notes together for at least one month. If a question arises later—a disputed charge, a missing deposit, a check that bounced—you will have the documentation to trace what happened and when.
What happens after reconciliation is complete
Reconciliation is a snapshot. It confirms that your records and the bank's records matched on a specific date. It does not mean your account will stay balanced forever. New transactions will post. You will write new checks. Deposits will arrive. Your next statement will show a different balance, and you will reconcile again.
The value of completing this final step is that you know your starting point is correct. If your next reconciliation shows a discrepancy, you know the error happened after the last reconciliation, not before. This narrows the search and makes finding problems faster.
Frequently Asked Questions
What if I find an error after I have already finished reconciliation?
If you discover a mistake in a transaction that you have already reconciled, correct it in your checkbook and recalculate your current balance. You do not need to redo the entire previous reconciliation—just adjust forward from where you are now. The next time you reconcile, the bank statement will show whether the transaction posted correctly.
Can I reconcile my account if I have not received the bank statement yet?
No. Reconciliation requires the official bank statement, which shows what the bank has recorded. You can compare your checkbook to online banking, but that is not the same as reconciliation. Wait for the statement to arrive or read it from your bank's website, then reconcile against that official record.
Do I need to reconcile every month?
Most banks recommend it, and it is the fastest way to catch errors early. If you reconcile monthly, each reconciliation covers only 30 days of transactions, so finding a mistake is quicker. If you reconcile quarterly or annually, you have months of transactions to search through if something is wrong.
What if the difference is only a few cents?
A few cents usually means a math error in your adjustments, not a missing transaction. Recalculate your deposits in transit and outstanding checks. If the difference persists and you cannot find the error, contact the bank—it is possible a transaction posted at a slightly different amount than you expected, such as a fee or interest.
Is reconciliation the same as balancing my checkbook?
Balancing your checkbook means making sure your records are correct. Reconciliation means comparing your records to the bank's records and confirming they match. Reconciliation is the final step that proves your checkbook is balanced correctly.
