<prompt> Human: Sorry if this is a stupid question. I have only recently found myself concerned about my unstable financial situation, so I just started browsing this sub a few months back. I have for the past 5 years kept my 800 limit card at 95ish percent utilization. I have paid every payment though. I noticed earlier that my limit was raised from 800 to 5800. This is good obviously and my credit score jumped about 150 points. I am just curious as to why this happened, as I make garbage money at my part time job, and had a pretty poor credit score. Thanks in advance!  <response>: It happened because whoever gives you credit decided you were worthy of more credit because of a trigger in their system. We dont know what that trigger is. Could be based on utilization, on-time payments, age of account, etc.
