If you think humans are bad at guessing how interest rates and percentage growth works then I have a surprise for you. You're wrong.
We aren't bad at it.
We SUCK at it. Hard.
Combine this with a population that doesn’t fully understand how their credit cards work in general and, well, it's bad news bears.
In testament to those two facts I was inspired to make this video to explain how interest on a credit card works, as well as talk about minimum payments, and run through a few examples. It’s all stuff that is good to know, even if you pay off your credit card every month!
