First you cross your fingers hoping you’ll get approved for the credit card you want
. Then you cross them again hoping the credit limit will be generous enough to get you what you want. Maybe you need it to pay for some expensive dental work you have to get done. Or perhaps you are applying for a 0% balance-transfer offer
so you can transfer debt from other, higher-interest cards. Either way, the credit limit they give you is a few hundred, or a few thousand dollars short of what you need — and you have no idea why. How did they even come up with that number?
