Table Structures and Columns (Weekly Budget & Forecast Sheet)

The core of this business-use template is structured as a detailed weekly table with the following columns:

Formulas Required

The template relies on a combination of built-in Excel functions for dynamic calculation and automation:

• Auto-Date Generation (Week Start Date):
  =DATE(YEAR(TODAY()),1,1)+WEEKDAY(DATE(YEAR(TODAY()),1,1),2)-2+(ROW()-ROW($A$2))*7
  This formula auto-populates sequential week start dates starting from the first Monday of the year.
• Variance (Actual vs. Budget):
  =D2-C2 (where D = Actual, C = Budget)
• Variance %:
  =E2/C2 (with formatting to show as percentage)
• Forecasted Sales:
  =VLOOKUP($A2, 'Historical Data'!$A:$F, 5, FALSE)*$G$1
  Uses historical average and a seasonality multiplier from the Forecast Assumptions sheet.
• Forecast Accuracy:
  =IF(AND(C2<>"",D2<>""), (1-ABS(D2-F2)/D2)*100, "")
  Calculates accuracy only when both actual and forecast values are populated.
• Dynamic Rolling Average:
  =AVERAGE(OFFSET(C3, -4, 0, 5)) (for last 5 weeks' average)

Conditional Formatting Rules

To enhance visual interpretation and highlight key trends:

• Budget vs. Actual Variance:
  - Red fill for negative variance (under budget)
  - Green fill for positive variance (over budget)
• Variance %:
  - Orange text if > 5% deviation
  - Red if > 10% underperformance
• Forecast Accuracy:
  - Green (95–100%)
  - Yellow (90–94%)
  - Red (<90%)
