<prompt> Human: To keep things concise, I had 3 active, open credit cards in great standings all with low limits. I have always paid off the cards debt in full, every month. Literally always. My credit score was 797. 2 of the cards have rewards that I benefit from, and the 3rd has none. This was the first card I was eligible for, low limit 3k, no rewards; just a start up card. After several years, I found myself using this card about once a month, just to keep it active, and ultimately realized I simply dont spend enough money to justify 3 cards. So, I decided to cancel it with no outstanding debts.Low and behold my credit score went down 30 points, to 767 once I did this. Should I have asked to increase my limit on one of my remaining cards? Why did it drop by this much? Is this amount typical? The interweb says 10 points is averageWhat actually happened and why?  <response>: 1. Dont obsess over your already very good credit score. Youve dropped 30 points from a very good credit score to a very good credit score.2. You have reduced your credit limitlines of credit and increased your utilization. That impacts your credit score.
