If you’re running Facebook Ads or Google Ads, you’re probably tracking ROAS and CPA religiously. But here’s the truth: these metrics can be dangerously misleading when it comes to scaling.

ROAS (Return on Ad Spend) and CPA (Cost Per Acquisition) show you averages. They reflect how your campaigns have performed up to this point. But they say nothing about what happens when you increase your ad budget. A solid ROAS today doesn’t guarantee that your next €1,000 will be profitable.

This is where Marginal ROAS comes in a metric every freelance paid media expert, senior traffic manager, or ads manager should embrace to unlock profitable scaling.


What Is Marginal ROAS?

Marginal ROAS is the additional return you get for each additional euro you spend. It's calculated like this:

Marginal ROAS = Δ Conversion Value / Δ Spend

In simpler terms, it measures the return of your next euro, not your last one. And that distinction makes all the difference.


Why Marginal ROAS Matters More Than You Think

Real-Time Profitability
Marginal ROAS helps you spot exactly when scaling stops making sense. It keeps your budget lean and performance-focused.

Smarter Budget Allocation
By comparing Marginal ROAS across campaigns or platforms (Google Ads vs Meta Ads, for instance), you can reallocate your budget where it delivers the best return.

Predictive, Not Reactive
Traditional ROAS reflects past performance. Marginal ROAS anticipates future performance. That’s a game-changer for every freelance PPC expert aiming for strategic, long-term growth.
