Formulas Required

Key formulas enable dynamic updates and intelligent resource planning:

• Current Stock Qty = Initial Stock Qty + Inbound - Outbound: Auto-updates in the Inventory Master List using SUMIFS across Movement Log.
• Reorder Point = (Monthly Consumption Rate × Lead Time Days) + Safety Stock Level: Implemented in Reorder Point Calculator.
• Forecasted Sales Units = Historical Sales Units × Seasonal Adjustment Factor: Used in Demand Forecasting.
• Trend Change % = ((Current Month Value - Previous Month Value) / Previous Month Value) × 100: Calculates performance trends in Dashboard Summary.
• Stockout Risk = IF(Current Stock Qty < Reorder Point, "High", "Low"): Uses conditional logic to flag low stock risks.
• Inventory Turnover Rate = COGS / Average Inventory (Monthly): Calculated in a hidden helper row for analytics.

Conditional Formatting

Visual alerts improve decision-making through color-coded flags:

• Red highlight: When Current Stock Qty < Reorder Point (low stock warning).
• Yellow highlight: When Forecasted Sales exceed 120% of historical average.
• Green highlight: When Safety Stock is above 90% of consumption rate.
• Divergent color fills in Dashboard Summary for positive/negative trend changes.
• Icons (using conditional formatting with shapes): A red "⚠️" appears when inventory movement exceeds daily capacity limits.
