The Comparable Sales Growth Calculator is a practical tool used in business and retail analytics to assess the performance of a store or business by comparing current sales to previous sales. This metric is vital for measuring organic growth without considering new store openings or acquisitions.
Formula
The formula for calculating comparable sales growth is:
G = ((Sc − Sp) / Sp) × 100
Where:
- G is the comparable sales growth in percentage
- Sc is the current period’s sales
- Sp is the previous period’s sales
How to Use
- Enter the current period’s sales value.
- Enter the previous period’s sales value.
- Click the Calculate button.
- View the percentage growth in sales.
Example
If the current sales are $120,000 and previous sales were $100,000, then:
G = ((120000 – 100000) / 100000) × 100 = 20%
