Formulas Required for Sales Forecasting and Inventory Management

The template uses advanced Excel formulas to automate forecasting and inventory tracking:

• AVERAGEIFS(): Calculates average monthly sales for each product over the last 12 months.
• MONTH() / YEAR(): Extracts month/year from date fields for grouping.
• FORECAST.LINEAR(): Predicts future sales based on historical data trends.
• INDEX(MATCH()): Dynamically pulls product-specific seasonality factors into forecasts.
• SUMIFS(): Totals sales by product and date range for reporting.
• IFERROR(): Ensures formula errors are handled gracefully with defaults like "0".

Example formula in the Forecasting Engine:

=ROUND(AVERAGEIFS('Data Input'!C:C, 'Data Input'!A:A, [Product ID], 'Data Input'!B:B, ">="&DATE(YEAR([Date]), MONTH([Date])-12, 1), 'Data Input'!B:B, "<="&[Date]) * (1 + [Seasonality Factor]), 0)

Conditional Formatting for Visual Insights

The template applies dynamic conditional formatting to highlight critical data points:

• Inventory Alerts: Cells turn red if inventory falls below reorder threshold (e.g., <10 units).
• Sales Performance: Green background for forecasted sales > average, yellow for near-average, red for below.
• Trend Arrows: Up/down arrows next to monthly changes using icon sets.
