Table Structures & Columns

Monthly Inventory Tracker Sheet

This sheet tracks real-time inventory movements for each product line on a monthly basis. The table structure includes the following columns:

Monthly Forecast & Reorder Alerts Sheet

This sheet uses historical data to predict future inventory needs and identify when to reorder. It includes:

• Product ID: Links back to the tracker sheet.
• Avg Monthly Demand (Last 3 Months): Rolling average of units used.
• Lead Time (Days): Supplier delivery time in days.
• Reorder Point: Formula-driven calculation: (Avg Daily Demand × Lead Time) + Safety Stock.
• Safety Stock Level: Buffer inventory to prevent stockouts during lead time variability.
• Recommended Order Quantity: Based on EOQ formula: √(2DS/H), where D=demand, S=order cost, H=holding cost.
• Next Reorder Date: Predicts when to place next order based on current stock and lead time.
• Status Alert: Conditional formatting flag (Red/Yellow/Green) for urgent reorder needs.

Dashboard & Performance Metrics Sheet

This visual dashboard provides startup founders and operations managers with key insights at a glance. Includes:

• Monthly Inventory Turnover Ratio: COGS / Average Inventory Value.
• Stockout Rate: (# of stockouts / total demand periods) × 100.
• Carrying Cost Percentage: Total holding cost / Total inventory value.
• Bullet charts showing actual vs. forecasted usage per category.
• Bar charts for top 5 high-cost items and slow-moving inventory (over 6 months).

Formulas Required

• Ending Inventory Formula: =BegInv + Purchases - Used
• Average Monthly Stock: =(Beginning_Inv + Ending_Inv)/2
• Total Inventory Value: =Ending_Inventory * Cost_per_Unit
• Reorder Point: =((Avg_Daily_Demand * Lead_Time) + Safety_Stock)
• EOQ (Economic Order Quantity): =SQRT((2*Annual_Demand*Order_Cost)/Holding_Cost_Per_Unit)

Conditional Formatting

To enhance usability and highlight critical data points, the following conditional formatting rules are applied:

• Red Highlight: Items with ending inventory below reorder point.
• Yellow Highlight: Ending inventory within 20% of reorder point (warning zone).
• Green Highlight: Stock above safety level, indicating healthy inventory.
• Data Bars: In the "Units Used" column to visualize consumption trends.
