• Variance %: =(Sales Variance / Forecasted Sales)*100 (use IFERROR for division by zero)

All formulas are pre-built in the template with error handling (e.g., IFERROR, ISBLANK) to prevent calculation errors during data entry. Users can modify formula logic through defined named ranges and input cells for customization without breaking the core model.

Conditional Formatting Rules
