The credit cards They're one of those topics that divide opinions. On the one hand, they offer you the possibility of financing your purchases, obtaining discounts, and earning points for redemptions. On the other hand, they can become a debt trap with extremely high interest rates if you don't know how to manage them well. Are they good or bad? The answer isn't that simple, because it depends on how you use them and how you understand key concepts, such as: total financial cost (TFC).
Total Financial Cost (TFC): What is it and why does it matter?
Let's start with the most important thing: the total financial cost (TFC)This indicator measures the real cost of financing with the card. It includes not only interest, but also fees, insurance, and other associated expenses. In other words, the CFT reflects the true cost of debt.
When you pay by credit card and decide to finance your purchase in installments, you're not just paying the value of the product. You're also paying the financing cost, which can vary depending on the card, the bank, and market conditions. The higher the CFT, the more expensive it is to finance yourself.
It's essential to check the APR before deciding to pay for something in installments. It's very easy to fall into the trap of "12 interest-free installments" that actually hide additional costs. "Interest-free" can be a misleading term if it doesn't include all the expenses that add up to the final balance.
How is the CFT calculated?
He CFT It is expressed as an annual percentage and is calculated by adding the cost of interest, insurance, administrative fees, and any other fees charged. Let's look at a simple example to understand it:
- You buy a refrigerator for $100,000 in 12 installments.
- The monthly interest is 3%.
- There is life insurance on the balance of the debt, which represents 0.5% per month.
Adding these costs together, the CFT could reach 50% or more in a year. That means you'll end up paying significantly more than the original $100,000.

Advantages of Credit Cards
Despite the costs, credit cards also have their advantages. advantages, especially if used strategically:
- Financing in emergency situationsIf you have an unexpected expense and don't have cash available, a credit card can be a useful tool to get you out of trouble.
- Rewards programsMany cards offer points, miles, or cashback for purchases you make. These benefits can be significant if you know how to take advantage of them.
- Purchases in installments: Sometimes, you can actually access interest-free installments, which makes it easier to purchase expensive products without paying extra.
- Better credit historyUsing your credit card responsibly can improve your credit history and help you access loans with better terms in the future.
Disadvantages of Credit Cards
Of course there are also disadvantages, and some are quite serious if you don't control your expenses:
- High InterestsCredit card interest rates are typically much higher than other personal loans. If you don't pay your balance in full each month, the cost of your debt can skyrocket.
- Late feesIf you're late paying, additional charges quickly add up, making the debt even harder to pay off.
- Commissions and hidden costsThere are many fees that can be added to card usage. The cost of life insurance on the balance, the renewal fee, or even the cost of issuing a new card are some examples.
- Risk of over-indebtedness: Because your credit limit can be high, it's easy to be tempted to spend more than you can afford. This is where cards become a dangerous trap.
Strategies for Using Credit Cards Smartly
If you want to take advantage of the benefits without falling into the typical problems, here are some strategies that may help you:
- Pay the full balance every month: If you pay off your full statement, you avoid paying interest. Using your credit card as an extension of your wallet, not a loan, is key.
- Avoid financing small purchases: It doesn't make sense to pay fees for things you could pay for in cash or with a debit card. The small amounts, when added together, end up creating a considerable debt balance.
- Always check the CFT before financingAs we've seen, the APR is the best way to know how much you'll pay in total. If that's not convenient for you, it's better to wait and save up to make the purchase in cash.
- Take advantage of real promotions and interest-free installmentsIf you find a promotion that is truly “interest-free” and you need the product, it may be a good opportunity to finance it at no extra cost.
