CME: The New KPI That Revolutionizes Advertising and Business Efficiency Measurement

For years, the industry has relied on metrics like ROAS or ROI to evaluate the profitability of advertising investment.

However, these metrics fall short when the goal is to understand whether the investment truly contributes to the business's net margin.

The industry needed a KPI capable of measuring not only the return, but the actual efficiency with which each euro invested boosts a brand's contribution margin.

Today, FSBD is introducing the KPI that fills this gap: Contribution Margin Efficiency (CME)

What is CME? CME (Contribution Margin Efficiency) is a new KPI designed to accurately measure whether advertising investment contributes efficiently to the business's Net Contribution Margin (NCM).

Formula: CME = NCM / Investment

This indicator allows you to know, with a single figure, how much net margin a brand generates for every euro invested in advertising, both in Walled Gardens (Google, Meta, TikTok) and DSPs (The Trade Desk, Adform, Illumin, DV360 & SA360).

Why was CME created? CME is made possible by the advanced analytics and measurement solution NCM (Net Contribution Margin) developed by FSBD and available exclusively to Business Tech Partner clients.

NCM allows for real-time measurement of:

• Net contribution margin per new customer
• Net contribution margin per returning customer
• Total contribution margin
• Actual impact of each channel, audience, campaign, and segment

Building on this foundation, CME adds a critical layer: how investment influences margin optimization.

For the first time, investment and margin can be interpreted in a correlated way—not as isolated metrics, but as dynamic elements of the business.

An Unprecedented View of Profitability

The CME offers unique advantages:

Direct Relationship Between Investment and Business Margin

Enables rapid detection of whether investment is:

• Maximizing Margin
• Destroying Margin
• Generating Hidden Inefficiencies

• The Trade Desk
• Adform
• DV360 & SA360

This allows for continuous recalculation and optimization of the CME.

Results Achieved During Black Month

During Black Month, FSBD's CME + NCM models generated outstanding results for high-volume clients:

• ROAS: 19.27
• ROI: 30.23
• CME: 18.09

These numbers not only demonstrate return on investment, but also real and sustained efficiency, even during periods of intense advertising competition.

The key: the power of FSBD's Data Warehouse and its ability to optimize audiences based on more than 60 billion parameters daily.

Why CME Will Be a Standard in 2026 Brands can no longer settle for metrics that focus solely on revenue. Competitiveness demands measuring:

• Actual Costs
• Net Margin
• Efficiency per Client
• Impact per Channel
• Ability to Scale Profitably

By 2025, CME will become the most reliable metric for understanding whether advertising investment is building or destroying business.

Conclusion

The CME is not just a new KPI.

It's the natural evolution the industry needed to connect advertising investment with true business profitability.

Thanks to FSBD's technology ecosystem—LLM, LAM, PCA, Data Warehouse, and dynamic clustering models—national and international brands are already improving their NCM, ROI, and CME with surgical precision.
