How do you calculate a 1.3 sales lift in quantity?

To calculate a 1.3 sales lift in quantity, you first need to determine the baseline sales quantity. Multiply this baseline quantity by 1.3 to find the new sales quantity after the lift. For example, if your baseline sales are 100 units, a 1.3 sales lift would result in 100 x 1.3 = 130 units sold. This indicates a 30% increase in sales compared to the original quantity.
