Required Formulas

The template leverages several key formulas to automate calculations and ensure accuracy:

=SUMIFS(DailyInventoryLog!$F:$F, DailyInventoryLog!$B:$B, [@ProductID], DailyInventoryLog!$C:$C, "Incoming")
// Sum of all incoming quantities for a given product

=SUMIFS(DailyInventoryLog!$F:$F, DailyInventoryLog!$B:$B, [@ProductID], DailyInventoryLog!$C:$C, "Outgoing")
// Sum of all outgoing quantities

=[@Beginning Stock] + [Total Inbound] - [Total Outbound]
// Calculated ending stock

=IF([@Ending Stock]/[@Average Monthly Sales Volume] < 7, "Low", IF([@Ending Stock]/[@Average Monthly Sales Volume] > 30, "Overstocked", "Optimal"))
// Auto-labels inventory status based on days of supply

=SQRT((2 * AnnualDemand * OrderingCost) / HoldingCostPerUnit)
// EOQ formula (to be used in Strategy Planning sheet with inputs)

=AVERAGEIFS(DailyInventoryLog!$A:$A, DailyInventoryLog!$B:$B, [@ProductID], DailyInventoryLog!$C:$C, "Incoming")
// Average delivery time for incoming shipments

Conditional Formatting Rules

• Stock Status Column: Red background for “Low” (text in white), yellow for “High”, green for “Optimal”, and dark red for “Overstocked”.
• Days of Stock on Hand: Color scale from blue (low) to red (high).
• Performance Score: Green if ≥ 8, yellow if 6–7.9, red if < 6.
• Aging Inventory: Highlight items with ending stock >90 days of supply in a warning shade.
