Uplift measurement

liftstack measures uplift as the difference in performance between the winning variant and the control, translated into revenue terms wherever possible.

The calculation

Incremental revenue is calculated as: (exposures to winning variant) x (conversion rate difference) x (average order value). This gives you a concrete revenue number that you can use in reports and stakeholder conversations.

Confidence ranges

The uplift estimate includes a credible interval showing the range of plausible values. For example: “Estimated additional revenue: £14,200 (95% CI: £8,400 to £21,100).” This range reflects the remaining uncertainty in the estimate and helps you calibrate expectations.
