What it is#
Incremental sales are the extra sales a specific action — a campaign, promotion, or discount — actually caused, over and above the baseline that would have happened anyway. It is the sales figure with the campaign minus the counterfactual without it.
Why it’s tricky#
Raw campaign sales overstate impact, because some buyers would have purchased regardless. Isolating the true lift requires an incrementality test — a holdout or control group that doesn’t see the campaign — so the difference between treated and control reveals the causal effect, not mere correlation.
Why it matters#
Incremental sales are the honest basis for marketing ROI and budget decisions — you should credit a campaign only with the revenue it truly drove, not sales it merely coincided with. The same logic underlies incremental conversions and uplift modeling: measure what wouldn’t have happened otherwise.
