Formulas Required

The following formulas are essential to drive functionality:

• Inventory Master > Avg. Cost Per Unit: =AVERAGEIFS(Purchase_Cost, Item_ID, [Item ID])
• Stock Levels > Status: =IF(Quantity_On_Hand < Reorder_Level, "Low", IF(Quantity_On_Hand == 0, "Out of Stock", "In Stock"))
• Cost Summary > Total Inventory Value: =SUMPRODUCT(Stock_Levels!$C:$C * Inventory_Master!$F:$F)
• Cost Summary > Cost Variance (%): =((Current_Month_Total - Previous_Month_Total) / Previous_Month_Total) * 100
• Alerts > Triggered: =IF(AND(Quantity_On_Hand <= Reorder_Level, Quantity_On_Hand > 0), "Low Stock", IF(Quantity_On_Hand == 0, "Out of Stock", ""))
• Dashboards > Stock Turnover Rate: =SUM(Sales_Data!$F:$F) / SUM(Stock_Levels!$C:$C)

Conditional Formatting

To improve visibility and support cost control, the template uses conditional formatting:

• Low Stock Highlight: In the Stock Levels sheet, cells with quantity below reorder level are highlighted in red.
• High Inventory Value (Cost Risk): Items with purchase cost above $100 or average unit cost > $50 are shaded in yellow.
• Alerts Status: "Pending" alerts are shown in orange; "Resolved" is green; "Ignored" is gray.
• Dashboards: Negative cost variance values are highlighted in red to signal rising costs.
