Unlike a loan, where you get one lump sum all at once, a credit card gives you a credit limit — a maximum amount you're allowed to borrow at any time, which frees up again as you pay it back.
If you only ever pay the minimum, the bank starts charging interest on whatever's left — and that interest compounds, meaning next month's interest gets calculated on a balance that now includes the previous month's interest too.
Here's a simple example. Say you carry an AED 5,000 balance on a card charging 3% interest a month (roughly 36% a year, a fairly normal credit card rate), and you only ever pay the minimum. That 3% keeps getting added to a balance that barely shrinks, so most of what you pay each month goes toward interest, not the amount you actually spent. It's the same compounding idea that makes savings grow over time — just working against you instead of for you.
The simplest rule that avoids all of this: only spend what you already have, or are certain you'll have by the due date — the same discipline you'd use with a debit card. Then pay off the full statement balance every single month, before the due date, instead of just the minimum.
Used this way, you're borrowing from the bank for a few weeks at most, and paying it all back inside the grace period — so you never pay a single dirham of interest. But you still get everything a credit card offers that a debit card doesn't: reward points, air miles, cashback, and purchase protection, all for spending money you already had anyway. Treated this way, a credit card isn't really "debt" in daily use at all — it's a debit card that happens to pay you back a little.
Under the Central Bank of the UAE's Consumer Protection Regulation, banks are required to give you a Key Facts Statement before you sign for a credit product. It's a standardized document, in plain language, that lays out:
This exists specifically so you're not just relying on what a salesperson tells you — you get the real numbers, in writing, before you sign anything.
Always ask for the Key Facts Statement before signing for a credit card, and actually read it — it's the one document guaranteed to show you the real cost, without any marketing language attached.
