How Is Math Used in Bank Reconciliation?

by Lorraine Tsutsui ; Updated July 27, 2017

Reconciling your bank statement with your checkbook is not as difficult as it appears. Simple addition and subtraction math skills are all that you need.


Reconciling a bank statement is the process of verifying the accuracy of the check register (list of entries) by comparing entries in the register with the entries in the bank statement.


Add all of your checking account deposits together. Some bank statements list the total deposits as total credits. See if your total is the same as the bank statement's total credits. Add the deposit total to your previous bank balance from your prior bank statement.

Add all your withdrawals and checks together, and then subtract the total from the prior balance just obtained. This should be the same as the bank statement balance.


Discrepancies in your bank balance can help identify which deposits or withdrawals are missing. A discrepancy may include a combination of missing or inaccurate entries. To determine the combination, all you need is addition and subtraction skills.


People often forget to record interest earned or service fees. Also, because banks often charge $30 per check on overdrawn accounts, it is important to keep an accurate account. Be certain to record in your check register any direct withdrawals and fees from your account as they occur.
