Sheet Names

The template comprises three dedicated sheets:

1. Forecast Overview: Central dashboard showing key metrics, monthly trends, and a visual Gantt chart.

3. Performance Tracking: A historical tracking log to compare forecasts vs. actuals over time with trend analysis.

Table Structures & Columns (Sales Forecast Data Sheet)

The primary data entry sheet, Sales Forecast Data, contains a structured table that enables accurate and scalable monthly forecasting:

Formulas Required

The template incorporates essential Excel formulas to automate forecasting and status tracking:

• Weighted Forecast Value (Column F):
  =D2*E2/100
  This calculates the contribution of each opportunity to the total forecast based on probability.
• Monthly Revenue Projection (Dashboard):
  On Forecast Overview, use:
  =SUMIFS('Sales Forecast Data'!$F:$F,'Sales Forecast Data'!$G:$G,">="&B1,'Sales Forecast Data'!$G:$G,"<"&EDATE(B1,1))
  Where B1 is the first date of the month. This sums weighted forecast values by target close month.
• Status Logic (Column H):
  =IF(ISBLANK(G2),"Forecasted",IF(G2<=TODAY(),"Closed","In Progress"))
• Forecast Accuracy (%):
  In the Performance Tracking sheet:
  =AVERAGEIFS('Sales Forecast Data'!$H:$H,'Sales Forecast Data'!$G:$G,">="&DATE(2024,1,1),'Sales Forecast Data'!$G:$G,"<"&DATE(2025,1,1), 'Sales Forecast Data'!$I:$I,"Closed")

Conditional Formatting Rules

Enhanced visual feedback is achieved through conditional formatting:

• Forecasted vs. Actual Close Month Color Coding:
  If the Target Close Month is more than 1 month ahead of today, apply light yellow fill; if overdue, apply red fill.
• Probability Thresholds:
  Color cells in Column E green if >70%, yellow for 40–70%, red for <40%.
• Gantt Chart Bars (in Overview sheet):
  Use data bars to represent opportunity duration and weight across the monthly timeline.
