How to calculate same-store sales

Separate the total sales revenue for the current period and the specific historical period after gathering the sales data. This is typically the most recent year or quarter. Subtract the total sales from the previous period from the total sales in the current period.

4. Calculate the percent change in sales

Multiply the result of the previous calculation by 100 after removing one. The result represents the percentage change in sales. A positive percentage represents an increase in same-store sales. However, a negative percentage represents a decrease in same-store sales.
