Detailed Steps for Promo Lift Analysis in Excel

Promo lift analysis is a crucial step in understanding the impact of promotional activities on sales and profitability, especially for a large brand like L'Oréal. With advancements in data analytics, the process has become increasingly precise. Below, we provide a step-by-step guide to conducting promo lift analysis using Excel, incorporating best practices and advanced techniques suitable for 2025.

1. Establish Baseline Metrics

To accurately measure the impact of promotions, it’s essential to first establish baseline metrics. This involves identifying periods where no promotions were active, allowing you to calculate the normal sales and margins.

• Identify Non-Promo Periods: Use Excel’s filtering capabilities to isolate periods without promotional activities. Typically, this involves excluding dates where promotional campaigns were not active.
• Create a Pivot Table: Generate a pivot table to summarize sales data by product, region, and time period. This helps in understanding the baseline performance.
• Calculate Averages: Use Excel formulas such as AVERAGE and STDEV to establish average sales figures and variability during these non-promo periods.

By establishing these baseline metrics, you create a benchmark against which promotional efforts can be measured.

2. Isolate and Flag Promo Periods

Next, you need to identify and flag the periods during which promotions were active. This requires a detailed examination of your promotional calendar and sales data.

• Use Conditional Formatting: Highlight cells representing promo periods in your dataset using Excel's conditional formatting. This visual cue helps in distinguishing promo from non-promo times.
• Tag Promo Data: Add an additional column to your dataset to flag promo periods. For instance, use a simple "1" for promo active and "0" for non-promo.
• Segment Data: Use Excel’s filtering options to separately analyze promo and non-promo sales figures.

This step ensures you can clearly differentiate and analyze the distinct impact of promotional activities.

3. Calculate Promo Lift Using Excel Formulas

To quantify the impact of promotions, calculate the promo lift by comparing promo period sales figures to baseline metrics.

• Basic Formula: The typical formula for promo lift is: (Sales During Promo - Baseline Sales) / Baseline Sales * 100%. This gives the percentage increase due to promotions.
• Use Excel Functions: Utilize functions like SUMIF and AVERAGEIF to sum and average sales data specifically during promo periods.
• Analyze Variability: Apply STDEVP to assess how promo lifts vary across different regions or products, providing deeper insights into effectiveness.

Calculating promo lift helps in quantifying the additional sales generated due to promotional activities.

4. Use Control Groups for Accurate Comparisons

Incorporating control groups is essential for a more accurate assessment of promo effectiveness, accounting for external influences.

• Select Control Groups: Identify similar products or regions that were not subjected to promotions during the same period.
• Compare Performance: Use Excel's VLOOKUP or INDEX/MATCH functions to compare performance between promo and control groups.
• Adjust for External Factors: Consider external factors like seasonality or competitor actions by analyzing control group variations.

This step ensures your analysis accounts for other variables, providing a clearer picture of promo effectiveness.

Conclusion

Conducting a promo lift analysis with Excel for L'Oréal involves a comprehensive approach combining baseline establishment, period isolation, lift calculation, and control group comparison.
