MER
MER (marketing efficiency ratio) is total revenue divided by total marketing spend for a period. Companies define "marketing spend" differently — some count only ads, others add influencers, agencies and tools — so always state what’s included.
Formula
MER = Total revenue ÷ Total marketing spend
Example
$10,000 revenue ÷ ($2,500 ads + $500 influencer fees) = 3.33x MER.

Questions
Is a higher MER always better?
Not on its own. A high MER on low-margin products can still lose money. Pair it with contribution margin or Blended Profit.
MER vs ROAS?
ROAS is usually per campaign and platform-attributed. MER is business-wide and not attributed.
