Examine the purchases and charges listed on your credit card bill and compare them to your receipts, explains Bankrate.com. Make sure you were not double billed for any purchases and that you actually made all of the purchases listed. Check also that you received credit for returns and refunds.
Applicable law requires your bank to list fees and charges such as interest, late charges and cash advance fees in a separate section on your credit card statement, indicates MyCreditUnion.gov. Make sure that you actually incurred these fees and that your bank calculated them accurately. Also, verify the previous balance listed on your statement. Check it against the prior month's statement. It should be zero if you paid your entire balance the prior month.
