What does Retail Promotion Sales Lift Calculator calculate?
Calculate promotion sales lift versus baseline sales. This page explains the inputs, method, and checks around the result instead of presenting an unexplained output alone.
Inputs and field meanings
Review these values before running the tool. The labels below come from the actual form so the guidance matches what you will use on this page.
- Promotion sales: required, minimum 0.
- Baseline sales: required, minimum 0.01.
Calculation method
Retail KPIs usually relate sales or profit to transactions, visitors, employees, or opening hours. Choose the denominator that answers the operational question rather than using a large number simply because it is available.
For discount and margin metrics, separate revenue, discount value, cost, and profit. Discount rate is not profit margin, and higher promotional sales do not automatically mean higher profit.
Checkable example
Example: a store with 50,000 revenue from 2,000 transactions averages 25 revenue per transaction. If 5,000 visitors produce 1,000 purchases, conversion is 20%.
