How to use it

  1. Enter your monthly social spend, your reach, your engagement rate, your click-through rate as a share of engaged people (not of reach), your conversion rate, and your average order value. The tool walks the funnel in order (reach to engaged to clicks to conversions to revenue), so each rate compounds on the last, which is why a small drop at the top of the funnel cascades into a large revenue difference at the bottom.
  2. Read ROI, monthly revenue, revenue minus spend (product costs not deducted), cost per click, and cost per conversion, with expected clicks and conversions in the funnel chart. Cost per conversion is the figure that decides whether the channel is viable, because it is the all-in cost to acquire one paying action and the number you compare directly against your average order value and margin.
  3. Use ROI and cost per conversion together rather than celebrating reach or engagement in isolation. Large reach with a weak conversion rate produces impressive vanity metrics and negative profit, while modest reach that converts well can quietly be your best channel. The funnel breakdown shows you exactly which stage is leaking.
  4. Find the binding constraint before increasing spend. A poor engagement rate is a content and targeting problem; a poor click-through rate is a creative and hook problem; a poor conversion rate is a landing-page and offer problem that lives downstream of social entirely. Fix the weakest stage first, then re-run to confirm the ROI actually moved before scaling budget.
  5. Re-run weekly during active campaigns and track cost per conversion by content type, since blended numbers hide the posts that work and the ones that drain budget. When the click lands on a dedicated page, pair this with the landing page conversion tool so the social spend and the page conversion are optimised as one connected funnel.
