<prompt> Human: Hello there!To preface this, Im 20 years old and have had a secured card with a small 300 limit for 10 months now. For the first 7 months, I kept my utilization to right around 10. Unfortunately early into the 7th month I had to make a purchase that used up 100 of the card. Dumb I know, but I had no choice. I have made the minimum payment of 25 the past 3 months, and just got to the point where I paid off the 225. Im a college student, so it took me a while to save up enough to even pay off the 300. But I finally did! Progress is a good thing right?So heres my question. The 3 months I didnt have it completely paid off, I was charged interest on my account. I noticed small amounts on my statement, between 5-8 each month. Im confused because I thought APR was a yearly not monthly occurrence. My interest rate is a whopping 19 on this card. Am I going to be charged a large lump sum at the end of the year or are these small interest payments all Ive owed? Assistant: APR is a yearly... unit? but its charged monthly. You wont owe more.Human: If so, why do these companies call it APR? Im trying to wrap my head around this. This whole credit thing is more difficult then my medical classes lol.  <response>: Think about it like this: you describe your speed in miles or km per hour even if youre only going to be driving for 15 minutes.Not a perfect analogy but pretty good.
