Table Structures and Columns (Example: Sales Forecast – Monthly Sheet)

The primary forecasting table is structured as follows:

Formulas Required

The template uses dynamic, non-breaking formulas across sheets. Key formulas include:

• Gross Revenue (Forecasted): =IF(Units_Sold>0, Units_Sold * Average_Price, 0)
• Sales Variance (%): =IF(Actual_Sales=0, IF(Forecasted_Revenue>0, 100%, 0), (Forecasted_Revenue - Actual_Sales) / Actual_Sales)
• Running Total Revenue: =SUMIF($B$2:B2, B2, $E$2:E2) (Cumulative revenue by product line)
• Monthly Growth Rate: =(Current_Month_Revenue - Prior_Month_Revenue) / Prior_Month_Revenue
• Scenario-Based Forecasting: Uses VLOOKUP, INDIRECT, and dynamic ranges to pull assumptions from the "Market Assumptions" sheet into forecast tables.
• Pivot Tables (in Dashboard): For aggregating revenue by category, region, or time period.

Conditional Formatting

Visual clarity is enhanced through conditional formatting rules:

• Sales variance above 15% in red (over-forecasting).
• Variance below -10% in yellow (under-forecasting).
• Revenue growth rate > 5% per month highlighted green.
• Empty forecast cells flagged with light gray background and icon set.
