Table Structures & Column Definitions

1. Product Inventory Master (Sheet: Product Inventory Master)

The Cost Price (per unit) and Selling Price (per unit) are critical for calculating profit margins. All values are stored as decimal numbers with two decimal places. The Current Stock Quantity is updated monthly and must be manually inputted or pulled from a warehouse system.

2. Monthly Cost Summary (Sheet: Monthly Cost Summary)

This sheet aggregates data from the master inventory list and applies formulas to compute COGS using the cost price and stock movements.

3. Cost Variance Report (Sheet: Cost Variance Report)

This table calculates deviations between planned and actual costs to highlight areas where cost control needs intervention.

Formulas Required

• =SUMIF(InventoryMaster!B:B, "Accessories", InventoryMaster!E:E) – Total cost of a category.
• =IF(B10 < C10, "Low Stock", IF(B10 >= C10, "In Stock", "Out of Range")) – Reorder trigger logic.
• =D3 * E3 – COGS calculation (stock quantity × cost price).
• =IF(F2 - G2 > 0, "Over Budget", "Under Budget") – Variance analysis.
• =ROUND((F2-G2)/G2, 3) – Variance percentage.

Conditional Formatting Rules

• Variance Highlighting: Red background if variance > 5%; green if < -5%.
• Low Stock Alerts: Yellow border when stock is below reorder point (e.g., under 50 units).
• Inactive Items: Gray background for products marked as inactive to distinguish them from active inventory.
• Budget Exceeded: Bold red text in variance cells with >10% over budget.
