About Uplift Estimate Calculator

Relative uplift sounds impressive while absolute uplift determines the business impact. Converting the absolute gain into extra conversions and their value is the only way to judge whether a change is worth shipping.

Formula

Uplift

Relative = (treatment - baseline)/baseline; extra conversions = visitors × absolute uplift

Frequently Asked Questions

Why quote both uplift measures?

A 40% relative uplift on a 0.1% baseline is still only 0.04 percentage points — trivial in absolute terms.

Should the uplift be assumed permanent?

No. Novelty effects fade, so re-measure after a few months before banking the gain.
