Free health-marketing calculators

Which calculator should you use?

Start with the CAC calculator to size your acquisition cost against your vertical, then run the LTV:CAC calculator to check whether that CAC is actually profitable, since a CAC only matters against lifetime value. When you are planning spend, the ad budget calculator works backwards from a customer target to the monthly budget it takes. To judge whole-account efficiency, the MER calculator shows blended revenue over spend (the number platforms can't inflate), and the POAS calculator layers in margin so you scale what's actually profitable, not just what looks efficient. Every result is directional; verify against your own account, and see the glossary for definitions of each metric.

The numbers only mean something in context. A 3:1 LTV:CAC ratio is healthy for a subscription supplement brand and thin for a high-touch telehealth offer, so read every result against your own margin and vertical benchmarks (see telehealth or GLP-1). When a figure looks off, the usual culprits are attribution (platform-reported ROAS overstates the truth without server-side tracking) and a media-only CAC that ignores creative and agency fees. Fixing those two is often worth more than any single budget change.
