Drop in Sales Calculator

Formula

To calculate the drop in sales ( $DS$ ):

$DS = \left( \frac{PS - CS}{PS} \right) \times 100$

Where:

$DS$ is the drop in sales (%)
$PS$ is the previous period sales (\$)
$CS$ is the current period sales (\$)

What is a Drop in Sales?

A drop in sales is a measure of the percentage of decline in sales from one period to another. The percentage is a ratio of the change in sales to the previous sales revenue.

Example Calculation 1

Let's assume the following values:

Previous Period Sales ( $PS$ ) = \$500,000
Current Period Sales ( $CS$ ) = \$400,000

Using the formula:

$DS = \left( \frac{500,000 - 400,000}{500,000} \right) \times 100 = 20\%$

The drop in sales is 20%.

Example Calculation 2

Let's assume the following values:

Previous Period Sales ( $PS$ ) = \$1,000,000
Current Period Sales ( $CS$ ) = \$750,000

Using the formula:

$DS = \left( \frac{1,000,000 - 750,000}{1,000,000} \right) \times 100 = 25\%$

The drop in sales is 25%.
