In some circumstances, customers don’t understand they’re not hitting the spending threshold to make the annual price worthwhile. Or they cease utilizing the cardboard altogether, but the price quietly renews, shrinking the web worth of any rewards they earned the 12 months earlier than. Until precisely how a lot you spend (and the place), you might pay extra in charges than you achieve in perks.

Even worse? In case your steadiness is excessive, this new penalty APR applies retroactively to present balances on some playing cards. You’re now paying triple the worth of any reward you earned. Banks love customers who slip up as soon as. They’re those who by no means see a free greenback once more.
