Random question about money

How much do you put on your credit card a month? I’m trying to figure out why I am low on money. I save a huge majority of my paycheck and sometimes use my credit card for purchases but I freak out if they are over 100 dollars. I basically have my bills come out of my checking and then I have a cushion of money in my checking of 1000 dollars. I try not to let my checking hit 1000 dollars so I use the rest of my paycheck and once it hits 1000 dollars I stop spending.

Sometimes I will put a few things on my credit card but freak out if it is over 100
