Is a credit card worth it?
Yes, if you master the one rule that changes everything in Colombia: purchases deferred to one (1) instalment generate no interest. Buy at one instalment, pay the full statement on time, and the card costs you nothing in interest while building your credit file.
No, if you defer to 24 or 36 instalments out of habit. Card rates live pinned to the usury ceiling — among the most expensive debt in the formal system. And watch cash advances: interest from day one plus a fixed fee. The line between useful card and trap is the number of instalments you pick at the terminal.
The second front is the cuota de manejo — the handling fee: 15,000 to 35,000 pesos a month at traditional banks, whether you use the card or not. Nu, RappiCard and Lulo charge $0 — over 300,000 pesos a year of difference. If you're after the lowest rate, Itaú has been holding the cheapest card rate in the market. Those two variables (handling fee and E.A.) decide 90% of the choice.
- ✓Purchases at 1 instalment: interest-free — the golden rule
- ✓Handling fee: $0 at Nu, RappiCard and Lulo; 15–35K/month at traditional banks
- ✓Card rates: near the usury ceiling — defer as little as possible
- ✓Cash advance: interest from day one + a fixed fee
