In October 2015, I was interviewed by the One Mile at a Time blog as part of a series on points and miles bloggers. In the comment section of that article, reader Maria asked if I had a template of the spreadsheet I use to track my credit cards. I replied that I did not have a template per se, but that I would try to post an article about my tracker. Unfortunately, I never got around to that, but since I am about to write a few articles evaluating my current credit card portfolio, I thought now would be a good time to talk about how I keep track of all my cards, their payment dates, sign-up bonus progress, and spending category bonuses.
