How Not to Use a Credit Builder Card

  • Do not exceed the credit limit

Not only are interest charges potentially high on a credit builder card if you don't pay your full balance each month, but the time to become debt free is significant the more you borrow. Since a larger portion of each payment goes towards interest charges when you borrow on a credit builder card, there's less money left to pay down your balance, extending the time to repay.

To make matters worse, only 51% of cardholders need to receive the stated APR of a credit card—the other 49% can, and usually do, pay a higher interest rate. And if you carry any balance from month to month, you'll owe interest at these higher rates.
