Having a credit card for decades doesn't necessarily mean understanding how its interest is calculated. Beneath Vivian Tu's latest Your Rich BFF Short, longtime cardholders are saying the explanation has revealed something they had never learned.
One viewer describes needing to slow the video down and listen again. Others point to decades of using cards without knowing how the calculation worked. The conversation isn't just about getting a first card: it's about discovering an unfamiliar part of an everyday bill.
Tu's credit card interest explainer reached about 46,000 views in its first 11 hours, already well beyond the audience her Shorts usually attract over a full first day. The comment section was more than five times as busy as on a usual first day, too.
The Short also promotes a financial question service. Its subject is a practical turn from her recent uploads about Venmo etiquette and what buyers actually get when they purchase cryptocurrency. Here, the recurring question from viewers is more immediate: how could they have used credit for so long without understanding the math?

Oh my God. I didn't know that this is how they calculate interest. I have had credit cards for 33 years! 😂😂😂
Thank you. 🙏@amitabhsom7489See it on YouTubeIn all of my 48 years, I have never heard anyone break this down. Thank you, Vivian!
@chrisguerrero-j9dSee it on YouTubeI need to slow this down and listen to it a few more times. Because if that’s how they do the math no wonder credit card debt is hell.
