Formulas Required

This template leverages dynamic Excel formulas to automate calculations and ensure accuracy:

• =IFERROR(AVERAGEIFS('Historical Trends'!$C:$C, 'Historical Trends'!$A:$A, A2), 0) – Calculates average historical sales for a given category.
• =FORECAST.LINEAR(MONTH(TODAY()), 'Historical Trends'!$C:$C, 'Historical Trends'!$B:$B) – Projects future values based on linear regression using time and past data.
• =IF(Actual_Sales > Target_Sales, "Above", IF(Actual_Sales = Target_Sales, "On Track", "Below")) – Generates performance status for visual indicators.
• =SUMIFS('Monthly Sales Data'!$C:$C, 'Monthly Sales Data'!$A:$A, EOMONTH(TODAY(),-1)) – Pulls total actual sales for the previous month dynamically.
• =ROUND(Actual_Sales * (1 + Growth_Rate), 2) – Applies user-defined growth rate to forecast next month's values.

Conditional Formatting
