What is Percentage Increase in Sales?

Percentage increase in sales represents the extent to which your sales have grown over a specific period, expressed as a percentage. This metric allows you to compare performance across different periods, identify trends, and evaluate the effectiveness of your sales strategies.

Why Calculate Percentage Increase in Sales?

Tracking your sales growth provides valuable information:

  • Performance Evaluation: It clearly shows whether your sales are improving or declining.
  • Strategy Assessment: Helps determine if your current sales and marketing efforts are effective.
  • Goal Setting: Provides a basis for setting realistic and achievable sales targets.
  • Investment Decisions: A positive sales growth trend can attract investors and secure funding.

The Formula

The formula to calculate percentage increase in sales is:

Percentage Increase = [(New Sales - Old Sales) / Old Sales] x 100

Step-by-Step Calculation

  1. Gather Your Data: Obtain your sales figures for the two periods you want to compare. Ensure you're using net sales (total revenue minus returns, allowances, and discounts).
  2. Subtract: Subtract the old sales figure from the new sales figure.
  3. Divide: Divide the result by the old sales figure.
  4. Multiply: Multiply the result by 100 to express it as a percentage.

Example Calculation

Let's say your company's sales were $50,000 last year and $75,000 this year.

  1. New Sales: $75,000
  2. Old Sales: $50,000
  3. Calculation: [($75,000 - $50,000) / $50,000] x 100 = 50%

Your sales increased by 50%.

Interpreting Your Sales Growth

A positive percentage indicates growth, while a negative percentage signifies a decline. However, understanding the number requires context:

  • Industry Benchmarks: Compare your growth rate to industry averages to see how you stack up.
  • Company History: Analyze your sales growth over multiple periods to identify trends.
  • Market Conditions: Consider external factors like economic conditions and competitor activity.

Beyond the Basic Calculation

For a more in-depth analysis, consider these additional metrics:

  • Monthly Growth Rate: Provides a more granular view of sales performance.
  • Customer Acquisition Cost (CAC): Helps assess the efficiency of your customer acquisition efforts.
  • Customer Lifetime Value (CLTV): Predicts the total revenue a customer will generate throughout their relationship with your company.
