• Variance: =D2-E2
• Variance %: =IF(E2=0, "N/A", (F2/E2)*100)
• Status: =IF(ABS(F2) <= E2*0.1, "On Target", IF(F2 > 0, "Overperformed", "Underperforming"))
• Forecast Accuracy: =IF(E3=0, 0, (1 - ABS(F3)/E3))*100
• Dynamic Table References: Uses structured tables (#Table) with the SUMIFS, COUNTIFS, and AVERAGEIF functions for real-time aggregation.
• Data Validation: Ensures only valid dates, predefined product lines, and non-negative sales figures are entered.
