Marketing Calculators

Campaign metrics are simple divisions that get compared badly. Every tool here is one number divided by another; the value is in knowing which pair to divide and what the result actually implies.

The money metrics come first. ROAS is revenue over ad spend, and on its own it is close to meaningless — a 3× ROAS is excellent at a 60% gross margin and a slow bleed at 25%. The calculator therefore reports break-even ROAS alongside it. Advertising ROI goes further and works from gross profit rather than revenue, which is the version a finance team will accept.

The traffic metrics price and convert attention. CPC and CPM tell you what clicks and impressions cost; CTR tells you how well the creative earns them; conversion rate tells you what happens after the click. Read in that order they form a funnel, and the weakest ratio is where the money is going.

Email open rate and engagement rate cover owned and social channels. Both include the version of the metric that people usually want but rarely compute: click-to-open rate, which separates the subject line from the content, and engagement by reach rather than by follower count, which is the only fair comparison between accounts of different sizes.

The two outliers are the most useful for planning. SEO traffic value puts an advertising price on an organic ranking by combining search volume, a position CTR curve and cost per click — the closest thing to a defensible number for what SEO work is worth. And lead conversion tracks a funnel from raw lead to closed deal, producing stage conversion rates and a cost per lead.
