Incremental Sales Analysis: Measuring True Discount Impact
Understanding whether discounts drive genuine additional revenue requires sophisticated tracking and comparative analysis techniques. This comprehensive guide will help you definitively measure your promotions' true economic value.
Key Performance Metrics for Discount Effectiveness
| Metric | What It Reveals | Calculation Method |
|---|---|---|
| Incremental Revenue | Additional sales generated specifically by the promotion | (Discounted Period Revenue - Expected Base Revenue) |
| Lift Percentage | Percentage increase in sales directly attributed to discount | (Incremental Revenue / Base Revenue) * 100 |
| Marginal Profitability | Net profit generated after accounting for discount costs | Incremental Revenue - Discount Expenditure |

- •Identify statistically significant deviations from baseline performance
