Sheet: Forecast Model

Formulas Required

• Growth Rate Calculation: In the Forecast Model, use: =IFERROR((B3 - B2)/B2, 0) (where B3 is current month and B2 is previous month)
• Average Growth Rate: =AVERAGE(Forecast_Model!D:D) – computes the average growth rate over historical periods.
• Forecasted Revenue: =INDEX(Historical_Sales_Data!B:B, MATCH(A2, Historical_Sales_Data!A:A, 0)) * (1 + $F$2) (where F2 holds the average growth rate from Settings)
• Rolling 3-Month Average: =AVERAGE(OFFSET(B5, -2, 0, 3, 1)) – used in the Dashboard to smooth trends.

Conditional Formatting

This template uses subtle but effective conditional formatting to enhance readability and highlight important data:

• Positive Growth: Cells with positive growth rates (e.g., +3.5%) are highlighted in green.
• Negative Growth: Negative values appear in red with bold font.
• Benchmark Thresholds: Forecasted revenue cells turn yellow if below the 3-month average; light blue if above target.
• Top 3 Values: In the Dashboard, top three forecasted revenues are highlighted in a gradient blue scale.
