<prompt> Human: As the title says, I recently found out there have been a few months where I was charged for interest due to a grace period. I had no idea it was a thing, but now I was made aware of it. With my Capital One Quicksilver card it basically works like this: you have a total, if you make the full payment every month, you will not be charged a fee. If you make a full payment one month, then the next you do not, you will be taken out of the grace period and you must make 2 more consecutive full payments before being brought back into the grace period.So in the last 6 months Ive been charged 120 for these charges. Which is a ton of money when youre living paycheck to paycheck. I always tried to pay it off entirely every month, but I was struggling for a few months and had 2 slip ups total in the last 8 months, which resulted in my getting removed from the grace period. My question is mostly, are there any cards I could get that do not have this type of thing? I always had the understanding that you were not charged interest unless you did not pay off the full amount. And if you did get charged interest, it was based on the leftover amount that you borrowed.Quick edit: Before Im berated about my lack of understanding or something regarding credit card knowledge, I have always paid it in full every month. I only had 2 months where I missed paying it off and had a leftover balance of like 100.  <response>: I have always paid it in full every month. I only had 2 months where I missed paying it off and had a leftover balance of like 100.You contradict yourself here. If you missed paying it off twice then you dont always pay it off in full. In fact, you say you:had 2 slip ups total in the last 8 monthsThose 2 slip ups are the reason you were charged interest. You have to pay the statement balance in full and you have to pay it in full every month in order to avoid interest. If you slip up and only pay the minimum or are late on the payment or whatever, they will charge you interest.
