The minimum payment is not a repayment strategy. It is the smallest amount required to keep the account current. When you pay only the minimum, the unpaid balance can continue to generate finance charges every month.
The danger is that the payment may feel manageable while the debt declines slowly. A large part of the payment can go to interest rather than principal, especially when the finance charge is high. This is why a small purchase can become expensive if it is carried for many months.
Use the minimum payment simulator before revolving a balance. If the payoff time is longer than expected or the interest is close to the original purchase amount, treat that as a warning sign and pay more than the minimum whenever possible.
