What formulas do the calculators use?
Standard ones, shown beside every result so a number can be checked by hand. The most used:
| Figure | Formula |
|---|---|
| Engagement rate | (likes + comments + shares) ÷ (followers × posts) × 100 |
| Reach rate | reach ÷ followers × 100 |
| Click-through rate | clicks ÷ impressions × 100 |
| Conversion rate | conversions ÷ clicks × 100 |
| ROI | (revenue − spend) ÷ spend × 100 |
| CPM | spend ÷ impressions × 1,000 |
| Cost per lead | spend ÷ leads |
The inputs come from each platform’s analytics, which SkedCast gathers for every connected account in analytics. For limits and specs rather than formulas, see the checkers.
