Practical Example

Scenario

A DTC brand calculates their blended marketing efficiency.

Calculation

Monthly revenue: $500K. Total marketing spend: $110K (paid + email platform + influencer). MER = $500K ÷ $110K = 4.55:1

Result

At 4.55:1 MER with 60% margin, marketing is generating $190K gross profit on $110K spend—healthy efficiency

Pro Tips

  • 1Track MER weekly alongside platform-specific ROAS to catch efficiency changes
  • 2Include ALL marketing costs: paid media, influencers, email platform, agency fees, creative
  • 3MER should improve over time as retention and organic compound—if declining, investigate

Common Mistakes to Avoid

Only including paid media spend, ignoring email, organic, and other marketing costs
Expecting MER to stay constant while scaling—it often decreases at higher spend levels
Not accounting for seasonality when evaluating MER trends

Frequently asked questions

MER includes all marketing spend (email platforms, agencies, creative, influencers). Blended ROAS often only includes paid media. MER counts more of your spend but is harder to calculate precisely.

MER typically decreases as you scale (diminishing returns on acquisition). Well-run brands might go from 5:1 at $1M to 3.5:1 at $10M. The key is maintaining profitability, not a specific ratio.
