Enter the current period sales (\$) and the previous period sales (\$) into the Change in Sales Calculator. The calculator will evaluate and display the Change in Sales.

## Change in Sales Formula

The following formula is used to calculate the Change in Sales (\$).

ΔS = CS – PS

• Where ΔS is the Change in Sales (\$)
• CS is the current period sales (\$)
• PS is the previous period sales (\$)

## How to Calculate Change in Sales?

The following example problems outline how to calculate Change in Sales (\$).

Example Problem #1:

1. First, determine the current period sales (\$).
1. The current period sales (\$) is given as: 7,000.
2. Next, determine the previous period sales (\$).
1. The previous period sales (\$) is provided as: 5,000.
3. Finally, calculate the Change in Sales (\$) using the equation above:

ΔS = CS – PS

The values given above are inserted into the equation below:

ΔS = 7,000 – 5,000 = 2,000 (\$)

Example Problem #2:

For this problem, the variables needed are provided below:

current period sales (\$) = 700

previous period sales (\$) = 300

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

ΔS = CS – PS = ?
