Calculate blended marketing efficiency
Compare total net revenue with total media spend.
The scenario
A store records $90,000 in net revenue and spends $15,000 on paid media.
The blended ratio is 6×. It includes revenue from organic, existing customers, and other efforts, so it is an overall efficiency check.
Apply it to your own work
Define which media costs and sales belong in scope. Compare the ratio with contribution and new-customer volume before deciding whether to scale.
What to watch for
A blended ratio can improve when paid spend falls while prior demand continues. It is not a substitute for incrementality measurement.
Use the blended number as a guardrail
If media spend drops from $15,000 to $12,000 and net revenue stays at $90,000, the ratio rises from 6× to 7.5×. That could be efficiency or simply the persistence of demand from earlier activity.
Track new customers, contribution after media, and changes in channel mix. Compare multiple periods and consider the time between spend and orders. Keep agency and creative costs consistently included or excluded before interpreting trends.
