Why have I been charged interest on 0% credit card?

Understanding Interest Charges on 0% Credit Cards

Many credit cards offer enticing 0% introductory APRs to attract new customers and encourage spending. While these offers provide temporary financial relief, it’s crucial to understand the consequences of carrying a balance beyond the promotional period.

How 0% APR Works

A 0% APR means that you won’t be charged interest on your purchases or balance transfer for a specified period, typically ranging from 6 to 18 months. However, this introductory rate is not permanent. Once the promotional period expires, the interest rate on your card will revert to its regular APR, which can be much higher.

Avoiding Interest Charges

The key to avoiding interest charges on a 0% credit card is to pay off your balance in full before the promotional period ends. This means making regular payments that cover both interest and principal. If you fail to pay off the balance before the deadline, interest will begin to accrue on the remaining balance.

Accumulating Interest

Once the introductory APR expires, interest charges will start to accumulate monthly. Interest is calculated based on your outstanding balance and the annual percentage rate (APR) of your card. The longer you carry a balance, the more interest you will pay.

Example

Let’s say you have a balance of $1,000 on your 0% credit card and the regular APR after the promotional period is 18%. If you fail to pay off the balance before the introductory period ends, you will be charged interest as follows:

• Month 1: $10.00 ($1,000 x 0.18% / 12)
• Month 2: $18.00 ($1,100 x 0.18% / 12)
• Month 3: $26.10 ($1,200 x 0.18% / 12)

Conclusion

0% credit cards can be a valuable tool for short-term financing and debt consolidation. However, it’s essential to plan ahead and pay off the balance in full before the introductory APR expires. Otherwise, you will be subject to interest charges that can add significantly to your overall cost. By carefully managing your spending and diligently paying down your balance, you can maximize the benefits of 0% credit card offers and avoid unnecessary interest expenses.
