Marginal Comparison

What is Marginal Comparison?

Marginal comparison, a feature enabled for a Custom Metric with the [numerator metric] / [denominator metric] format, is a calculation that provides insights into the incremental change of a ratio metric over a chosen comparison time period. It is calculated as Δ numerator / Δ denominator.

Marginal Comparison helps you answer questions like “What is the incremental value of each dollar?” and can be used with metrics like Cost per Sale or RoAS.
