Variance Analysis
Budget Variance
- Actual vs Budget amounts
- Percentage difference
- Favorable/unfavorable identification
- Trend analysis
Forecast Variance
- Actual vs Forecast amounts
- Track forecast accuracy
- Identify forecast bias
- Forecast adjustment recommendations
Multi-Account Analysis
- Revenue variance by product/segment
- Expense variance by department
- Account-level drill-down
- Root cause identification

Excel layout:
- Content starts at column B (column A is a narrow gutter)
- Rows 1-6: header banner with navy background, white title text, white subtitle
- Gridlines OFF. Freeze panes at B7.
- Footer as last row with generation date
- Every cell must have font, fill, alignment, and number format set
Number formats: _(* #,##0_);_(* (#,##0);_(* "-"_);_(@_) (default), $#,##0 (dollars), $#,##0.0,,"M" (millions), 0.0% (percent)
Variance coloring: Any cell showing a delta/change: green (2ECC71) if favorable, red (E74C3C) if unfavorable. Apply automatically based on value sign and metric context.
PowerPoint: Navy (0C142B) background, 16:9 widescreen, Poppins font, white text, amber (FFA30F) accent lines, card backgrounds 001F37.

Performance
- Analysis: ~1-3 minutes
- Scales to multiple years
- Handles 100+ accounts
- Efficient aggregation
Interpretation
Favorable Variance
- Actual > Budget (Revenue) ✅
- Actual < Budget (Expense) ✅
Unfavorable Variance
- Actual < Budget (Revenue) ❌
- Actual > Budget (Expense) ❌
% Variance
- <5%: Excellent forecast/budget accuracy
- 5-10%: Good, within normal range
- 10%+: Needs investigation
Workflow
FP&A Process:
1. /dr-extract --year 2025 (Get actuals)
2. /dr-reconcile --year 2025 (Validate data)
3. /dr-forecast-variance --year 2025 (Analyze variances)
4. Present findings to leadership (Board meeting)
Advanced Usage
Track forecast improvement
# Monthly variance tracking
/dr-forecast-variance --year 2025 --scenarios Actuals,Forecast --period 2025-01
/dr-forecast-variance --year 2025 --scenarios Actuals,Forecast --period 2025-02
# Compare forecast accuracy trend
Multi-year comparison
/dr-forecast-variance --year 2024 --scenarios Actuals,Budget
/dr-forecast-variance --year 2025 --scenarios Actuals,Budget
# Compare year-over-year performance
Scenario sensitivity
# Three different budget scenarios
/dr-forecast-variance --year 2025 --scenarios Actuals,Budget_Conservative,Budget_Aggressive
Error Handling
"Scenario not found" - Verify scenario exists in data
"No variance data" - Confirm Budget/Forecast scenarios available
"Large variance" - Review detailed Excel report for root causes
