Formulas Required

• Forecasted Sales Volume: Use exponential smoothing with a smoothing factor (α = 0.3):
  =IF(ROW()=2, [Actual Sales], α * [Actual Sales] + (1-α) * [Previous Forecast])
• Recommended Reorder Quantity:
  =MAX(0, Forecasted_Sales - Current_On_Hand + Safety_Stock)
• Forecast Accuracy:
  =IFERROR((1 - ABS([Actual Sales] - [Forecasted Sales]) / [Actual Sales]) * 100, 0)
• Rolling Average (for trends):
  =AVERAGE(OFFSET([Actual Sales], -4, 0, 5, 1)) (last five periods)

To enhance readability and highlight critical values:

• Overstock Alert: If Current On-Hand Inventory > Recommended Reorder Quantity + 50%, apply red fill.
