• Performance Dashboard: Interactive visualizations summarizing KPIs including forecast accuracy, month-over-month growth, and variance from budget.

Table Structures and Column Definitions

The primary table is structured in the Main Forecast & Budget (Planning View) sheet with the following columns:

Formulas Required

The template uses a combination of built-in Excel functions to automate calculations and maintain data integrity:

• =FORECAST.LINEAR(): Projects future sales based on historical data using linear regression.
• =IFERROR(): Ensures smooth operation when no historical data exists for a product.
• =SUMIFS(): Aggregates actual and forecasted values across multiple criteria (product, region).
• =(Forecasted Sales - Budgeted Sales) / Budgeted Sales: Calculates variance from budget.
• =(1 - ABS((Actual - Forecast) / Actual)) * 100: Computes forecast accuracy percentage.

Conditional Formatting Rules

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

• Variance from Budget: Red fill for values below -10%, yellow for -10% to +5%, green for above +5%.
• Forecast Accuracy: Green if above 85%, yellow if between 70–85%, red if below 70%.
• Missing Data: Light gray background for empty cells in Actual Sales column to prompt data entry.
