It is very easy and very important to reconcile your bank account each month when you receive your bank statement. You should first make sure you have written down all of your transactions in your check register. You can then get your bank statement and begin comparing the two. You should check off every entry on your statement with your register. When you are done, any payment transactions that are not on your statement that are in your register should be subtracted from the bank statement balance and any deposits not shown should be added to this number. In the end, the adjusted bank balance number should match your check register balance. This is how you reconcile your bank statement.
