Formulas Required

The template uses several dynamic formulas to ensure automatic updates and data integrity:

• Total Revenue: = Quantity * Selling Price per Unit (in Historical Sales Data sheet)
• Achievement Rate: = Actual Revenue / Projected Revenue (as percentage)
• Forecasted Monthly Revenue: = Previous Month’s Forecast × (1 + Base Growth Rate) × Seasonality Factor
• Trendline Projection: Uses Excel's =FORECAST.LINEAR() function based on historical revenue trends.
• Growth Rate Calculation: = (Current Period Revenue - Previous Period Revenue) / Previous Period Revenue

Conditional Formatting

To enhance readability and highlight key performance indicators, the following conditional formatting rules are applied:

• Underperformance Alerts: Cells with Achievement Rate < 90% are highlighted in red.
• Exceeded Forecasts: Achievement Rate ≥ 105% is marked in green.
• Growth Trends: Positive growth cells shown in light green; negative growth in light red.
• Near-Complete Milestones: In the Project Timeline sheet, cells turn amber when completion is within 10% of target date.
