It’s best to pay the balance off before its due. Usually get a statement before the due date. If you pay in full, then you pay no interest.
If you new to credit start with a Discover IT secured card. If you smart with it itll graduate to a non secured in a few months.
If discover denies you, capital one got a secured card thats easier to qualify for but i dont think it graduates to unsecured. Plus their customer service aint as good as Discovers. If its your only option tho then gotta start somewhere.
If you in college you might be able to get their student IT which is unsecured so you aint gotta make a deposit like a secured card.
After a year of using your unsecured card you should apply for a better card. I wouldn’t get one with annual fees unless you make a lot of money and can come out ahead in the rewards points.
So start off like this
Secured card(discover IT or Crapital One)
Then a decent no annual fee card(us bank cash+, amex cash magnet, amex blue cash everyday, chase freedom, etc)
Visa and MasterCard more accepted than Discover and Amex tho so if you start with discover you might want to find a decent visa or mastercard first instead of the american express.
Citi Double Cash card is a good 2% mastercard with no annual fee, but ive heard their customer service is hit n miss.
Credit agencies look at your credit utilization and age of accounts. So you never want to go above 30% credit utilization. Thats where having multiple cards helps if your card doesnt give you a limit increase.
Example: you need to buy 300 dollars worth of groceries but also need new tires for your car this week. Your first card has a limit of 1000 bucks. Your groceries will put you just under that 30 percent but if you buy the tires on that same card you goin over that 30. But your second card got a 2000 credit limit. So get the groceries on card one, and the tires on card two(assuming they aint expensive and wont cost over 30 percent of that 2000 limit). Pay both them shyts off at the end of the month and you good. Never had high utilization, and paid off so you aint paid interest.
Never ever max out a card. Even if you pay it off that same month it looks bad on you.
