I need to know the formula for finding the 'lost sales'. I'm given the following information.

a. New Output
b. Lost Output (Construction)
c. New Sales
d. New Gross Margin
e. New Gross Profit
f. Old Output
g. Old Sales
h. Old Gross Profit
i. Incremental Gross Profit

I thought the Lost Sales would equal to New Sales - Old Sales, but my assumption is incorrect.

To find the formula for calculating "lost sales," we need to consider the available information provided. Typically, lost sales are associated with the difference between potential sales and actual sales. However, in this case, we need to derive the formula using the given variables.

Based on the given information, we can derive the formula for lost sales as follows:

Lost Sales = Old Sales - New Sales

To understand why this formula differs from your initial assumption, let's break down the components of the formula:

- Old Sales: Represents the sales generated before any changes or improvements were made.
- New Sales: Denotes the sales achieved after the changes or improvements were implemented.

By subtracting the New Sales from the Old Sales, we can determine the lost sales. This calculation reflects the decrease in sales due to the changes or improvements made.

It's also worth noting that lost sales can occur due to a variety of factors, such as customer dissatisfaction, lack of product availability, or increased competition. Therefore, it's essential to analyze the data and context behind the figures to gain a complete understanding of the reasons for lost sales.
