Sheet Details and Table Structures

1. Monthly Forecast & Sales Data (Main Calculation Sheet)

This sheet contains the core dataset used for forecasting and stock tracking. It tracks actual monthly sales, compares them against forecasted values, and calculates variances.

2. Stock Control Dashboard (Overview Sheet)

This interactive dashboard provides a high-level view of inventory health across all products, including stock levels, reorder status, and forecast trends.

3. Product Master List (Reference Sheet)

This sheet serves as the central repository for all product information, including critical details used in forecasting and stock control.

4. Reorder Alerts & Action Log

This sheet automatically generates alerts based on current stock levels and upcoming forecasted demand.

Formulas Used (Key Examples)

• Variance: =Forecast - Actual (in each month column)
• Forecast Accuracy: =(1 - ABS(Variance) / Forecast) * 100
• Stockout Risk Logic: =IF(CurrentStock <= ReorderPoint, "High", IF(CurrentStock <= 2*ReorderPoint, "Medium", "Low"))
• Suggested Order Quantity: =MAX(0, ForecastedDemand + ReorderPoint - CurrentStock)
• Automatic Data Linking: Use VLOOKUP or XLOOKUP to pull Product Name and Category from Master List

Conditional Formatting Rules

To enhance readability and visual alerts, apply the following conditional formatting:

• Variance > 15%: Red fill with bold text (over-forecast)
• Variance < -10%: Yellow fill (under-forecast)
• Stockout Risk = "High": Bright red background
• Overstock Items: Orange shading (items with stock > 90 days of demand)
• Dashboards: Use data bars and color scales to visualize forecast accuracy and stock levels
