Why the lowest conversion rate isn't always the biggest leak
It's tempting to fix whichever stage has the worst-looking percentage, but a low rate at a low-volume stage can be worth far less than a smaller-looking drop at a high-volume one — the only way to know which stage actually deserves attention first is to convert each stage's improvement into real RM, not just compare percentages. This calculator models a 20% relative improvement at each stage independently (holding the others constant), then shows what that specific fix is worth in extra customers per year at your actual average customer value — so the ranking reflects real leverage, not just which number looks worst on a dashboard.
The visitor→lead→consult→customer structure defaults to clinic-style labels because aesthetic and dental practices are a priority vertical for us, but the same four-stage logic works for any funnel with a lead-to-appointment-to-sale structure — just read the labels as your own stages. A low lead-to-consult rate almost always points to a speed-to-lead or qualification problem rather than a marketing problem, which is why that stage often turns out to be the highest-leverage fix even when the marketing team gets blamed for a "traffic" issue.
Running this for an aesthetic or dental practice specifically? See aesthetic clinic marketing and dental clinic marketing, and our cost-per-consultation guide for the benchmark context behind these numbers. A live selling session has an extra stage this tool doesn't model — viewer to product-card tap, before add-to-cart even happens — see the live commerce ROI calculator, which does.
