Formulas Required

• Forecasting Formula:
  In the Sales Forecasting sheet, Column F uses a weighted formula: =ROUND(D4 * (1 + E4/100), 0) Where D4 is the historical average and E4 is the seasonality adjustment factor.
• Confidence Interval:
  For conservative estimates:
  =F4 * 0.85 (Low) and =F4 * 1.15 (High)
• Reorder Trigger:
  In the Stock Control Dashboard, use:
  =IF(AND(Dashboard!D2 <= DataInput!E2, Dashboard!D2 > 0), "REORDER", "")
• Current Stock Calculation:
  In the Inventory Ledger, Total Value is calculated as:
  =E4 * G4
• Running Balance:
  Use a SUMIF formula to track current inventory level per product based on inflows and outflows.
• Dynamic Date Ranges:
  The template uses the DATE function combined with EOMONTH to auto-generate monthly forecast periods.

Conditional Formatting

• Red background with white text for stock levels below reorder point.
• Yellow highlight for inventory levels at 80% of reorder threshold (warning zone).
• Green fill for stock above safe level (no action needed).
• Pink cells in forecast columns where confidence interval exceeds ±15%.
• Bar charts within cells to visualize variance between actual and forecasted sales.
