Intrinio likes to give its users the flexibility to calculate their own metrics and ratios- if you can see what is under the hood, it makes it easier to understand what the data is telling you. We do, however, calculate more than 100 of these data points for you, which saves time and computing power on your end.
Most investors don't care, or need to know the subtleties that go into calculating some of the more complex ratios, but for more advanced users the differences in methodologies can make a big difference. This post outlines a few of the data points that users have asked about. Feel free to post any you are interested in in the comments and we will add them as well.
