Why these live in one place

Most of these calculations exist somewhere online, scattered across single-purpose pages built for marketers rather than operators. The difference here is context: a fill rate page that tells you why fill rate on its own is a vanity metric, a CPC page that explains that in programmatic you bid a CPM and receive a CPC, a pacing tool that warns you when catching up means bidding up. The arithmetic is the easy part.
