Incremental Sales Lift Calculator

Formula

The formula to calculate the Incremental Sales Lift (L) is:

\[ L = (S_A - S_B) - (C_A - C_B) \]

Where:

L – The incremental sales lift.
S_A – The sales after the campaign.
S_B – The sales before the campaign.
C_A – The control group sales after the campaign.
C_B – The control group sales before the campaign.

Definition

Incremental Sales Lift (L): The additional sales generated as a direct result of the campaign, beyond what would have been achieved without it.
Sales After Campaign (S_A): The sales recorded after the campaign.
Sales Before Campaign (S_B): The sales recorded before the campaign.
Control Group Sales After Campaign (C_A): The sales recorded by the control group after the campaign.
Control Group Sales Before Campaign (C_B): The sales recorded by the control group before the campaign.

Example

Let's say the sales after the campaign (S_A) are $150,000, the sales before the campaign (S_B) are $100,000, the control group sales after the campaign (C_A) are $110,000, and the control group sales before the campaign (C_B) are $105,000. Using the formula:

\[ L = (150,000 - 100,000) - (110,000 - 105,000) = 50,000 - 5,000 = 45,000 \]

So, the incremental sales lift is $45,000.
