Key Formulas Used

The template leverages advanced Excel functions for dynamic forecasting and automation:

• SUMIFS + DATE Functions: Calculate monthly or quarterly sales by product using =SUMIFS(SalesAmountRange, DateRange, ">=StartMonth", DateRange, "<=EndMonth").
• FORECAST.LINEAR / TREND: Project future sales based on historical data trends.
• AVERAGEIFS + OFFSET: Compute rolling 3-, 6-, or 12-month average sales for stability.
• IF + AND Logic in Reorder Suggestions: Trigger reorder alerts when current stock < (reorder point).
• Purchase Order Quantity Formula: =MAX(0, ForecastedDemand - CurrentStock + SafetyStock) This ensures orders cover demand during lead time while maintaining safety stock.

Conditional Formatting Rules

To enhance visual interpretation and rapid decision-making, the following conditional formatting rules are applied:

• Current Stock Level: Red if below reorder point; yellow if within 10% of reorder point; green otherwise.
• Sales Variance: Highlight cells where actual sales deviate by more than ±15% from forecast using red or green highlights.
• Purchase Suggestions: Blue background for items with recommended order quantities greater than zero.
• Reorder Status: Conditional color-coding to indicate "Critical", "Warning", or "Optimal" inventory status.
