With interest rates easily exceeding 15%, the habit of only paying the minimum monthly installment can turn routine purchases into a financial snowball. It helps with daily life, facilitates online shopping, and offers benefits, but it can quickly become one of the most expensive credits on the market.

When is the credit card useful?

Works well for:

  • Emergency payments;
  • Points and miles accumulation;
  • Shopping protected by insurance;
  • Management of monthly expenses with full payment.

When it starts to weigh on the budget

It is an alert if:

  • You are paying the minimum every month.
  • The effort rate increases.
  • Accumulate installment purchases;
  • Use the card for essential expenses (food, electricity).

In these cases, the card ceases to be a tool and becomes disguised credit.

What to do to regain control

  • Pay the full amount whenever possible.
  • Avoid interest installment plans.
  • Reduce the limit temporarily;
  • Consider consolidating credits to lower charges.

The card is useful if disciplined. Otherwise, it becomes one of the budget's biggest enemies.

Feel like the card is weighing you down at the end of the month?
