Key Formulas Used in the Template

• Forecast Model (Column E, Forecast Model Sheet): =FORECAST.LINEAR(TODAY()+30, SalesHistory[Units Sold], SalesHistory[Date]) – Projects demand 30 days ahead using linear regression.
• Status in Product Inventory: =IF([@Current Stock Level] < [@Reorder Point], "Low Stock", "Sufficient") – Automatically flags inventory levels.
• Safety Stock Calculation: =MAX(0, [@[Reorder Point]] - [@[Current Stock Level]]) + ([@Lead Time (Days)] * AVERAGE(DailyDemand))
• Inventory Turnover Ratio: =SUM(Sales History[Units Sold]) / AVERAGE([@Current Stock Level], [@Previous Month Stock])
• Forecast Accuracy Metric (Dashboard): =1 - (SUM(ABS(Forecast - Actual)) / SUM(Actual))

Conditional Formatting Highlights

Dynamic visual cues ensure instant data comprehension:

• Low Stock Alert: Red background with bold text when Current Stock Level < Reorder Point.
• Benchmark Comparison: Green shading for forecasted units above actual historical average, yellow for close match, red for below average.
• Trend Arrows in Dashboard: Upward/downward arrows next to KPIs based on month-over-month change.
• Data Validation: Drop-down lists prevent invalid entries in Region and Sales Channel columns.
