Columns and Data Types

Key Formulas Required

• Growth Rate Application: In cell B21 (first forecast revenue): =IFERROR(LOOKUP(1,0/($B$2:$B$15<>""), $B$2:$B$15) * (1 + $J$2), 0) This formula retrieves the most recent historical sales value and applies the defined growth rate.
• Seasonality Adjustment: In cell B21: =B21 * $J$3 (applied after growth rate)
• Promotion Impact: In cell B21: =B21 * $J$4
• Units Forecast: In cell C21: =ROUND(B21 / AVERAGE($B$3:$B$15/$C$3:$C$15), 0) Uses historical average revenue per unit to project volume.
• Forecast Confidence: In cell D21: =IF(AND($J$6<=6, $J$3>=1.2), "High", IF($J$6<=12, "Medium", "Low"))
• Status Indicator: In cell E21: =IF(B21 > 0, "Active Forecast", "-")
• Auto-fill Month Headers (A20:A35): Use Excel’s DATE and SEQUENCE functions: =EDATE($J$5, SEQUENCE(12,1))

Conditional Formatting Rules

• Revenue Growth Highlight: Apply to B21:B35 – if value increases by >5% from prior month → green fill; if decreases → red fill.
• Status Indicator (E column): Green for "Active Forecast", gray for "-".
• Confidence Level (D21:D35): Green = High, Yellow = Medium, Red = Low.
• Data Entry Validation: All input cells in J2:J6 are restricted to valid ranges using Data Validation.
