<prompt> Human: I usually check mine every other day or so, mostly just to make sure theres nothing fishy on there.  <response>: Once a month for both my main bank account and credit cards. I have my credit cards payment dates all synced up to the 15th of each month. I pay everything I can with credit cards. So all outgoing transactions on my bank account are ATM withdrawals and one rent check a month. I know roughly how much I have in there to the nearest 500 or so.Im self-employed so I do check my business bank account anytime a deposit is supposed to have cleared or when I pay something out of that account to make sure that everything is correct. Usually once a month also but maybe more if Im running payroll once a quarter
