Why Calculate Sales Percentage Increase?

  • Track Performance: Measures progress against previous periods, highlighting successes and areas for improvement.
  • Inform Decision-Making: Provides data to guide resource allocation and strategic planning.
  • Attract Investors: Demonstrates business growth and potential for return on investment.

The Formula for Sales Percentage Increase

The basic formula is straightforward:

Sales Percentage Increase = [(Current Sales - Previous Sales) / Previous Sales] * 100

Where:

  • Current Sales: Total sales for the period you're analyzing.
  • Previous Sales: Total sales for the prior period you're comparing against.

Step-by-Step Calculation

  1. Gather Your Data: Collect sales data for the two periods you want to compare.
  2. Apply the Formula: Subtract the previous period's sales from the current period's sales.
  3. Divide: Divide the result by the previous period's sales.
  4. Multiply: Multiply by 100 to express the result as a percentage.

Example Calculation

Let's say your company had $50,000 in sales last quarter and $75,000 in sales this quarter. The calculation would be:

[(75,000 - 50,000) / 50,000] * 100 = 50%

This indicates a sales increase of 50%.
