<prompt> Human: Has anyone had an instance where their savings account in my case, Ally has paid out a lower amount in interest for the month even with no withdrawals? I noticed this months pay out was a little less than before even though I hadnt made any withdrawals and the amount should be increasing with interest.Any ideas what might be happening or should I just be contacting my bank?  <response>: Is it a small amount difference? It could just be that they paid interest 29 days this month instead of 3031. Sometimes it just depends how many days are in the month and if the firstlast day of the month falls on a weekend.
