1. WORKBOOK ARCHITECTURE & TAB BREAKDOWN

The pro forma xls workbook is engineered using a modular, decoupled architecture. This ensures strict separation of concerns between raw transactional data, structural assumptions, dynamic calculation engines, and executive reporting.

Tab Inventory & Data Flow Schema

• 01_Inputs (Global Assumptions):
  • Purpose: Houses macroeconomic variables, tax rates, inflation indices, discount rates, and operational scaling factors.
  • Data Flow: Feeds variables directly into 03_Model_Engine via named ranges and dynamic lookups.
• 02_Master (Master Data Table):
  • Purpose: Centralized repository for granular cost centers, headcount rosters, capital expenditure schedules, and revenue line items.
  • Data Flow: Acts as the primary database queried by the calculation engine.
• 03_Model_Engine (Dynamic Calculation Engine):
  • Purpose: Core crunching layer. Processes multi-year projections, debt schedules, working capital adjustments, and depreciation waterfalls.
  • Data Flow: Pulls from 01_Inputs and 02_Master; outputs structured financials to 04_Financial_Statements.
• 04_Financial_Statements (Pro Forma Statements):
  • Purpose: Standardized output reporting containing the Income Statement, Balance Sheet, and Statement of Cash Flows across a 5-year forecast horizon.
  • Data Flow: Aggregates outputs from 03_Model_Engine and feeds the 05_Executive_Dashboard.
• 05_Executive_Dashboard (Visual KPI Center):
  • Purpose: C-suite presentation layer featuring high-level performance cards, variance analysis, and unlevered/levered IRR outputs.
  • Data Flow: Consolidates metrics from 04_Financial_Statements and 06_Scenario_Manager.
• 06_Scenario_Manager (Sensitivity Matrix):
  • Purpose: Houses data tables for Base, Bull, and Bear case sensitivity analysis (e.g., Revenue Growth vs. COGS Expansion).
  • Data Flow: Dynamically overrides variables in 01_Inputs to stress-test the 03_Model_Engine.

2. MASTER DATA TABLE (MARKDOWN FORMAT)

The following table represents the normalized operational dataset residing in 02_Master. It captures a cross-section of enterprise cost centers, line items, and capital allocations.

3. EXPLICIT FORMULA GLOSSARY

The financial model relies on robust, error-trapped formulas to maintain structural integrity across worksheets.

=IFERROR(XLOOKUP(E14, 02_Master!A:A, 02_Master!F:F) * (1 + XLOOKUP(E14, 02_Master!A:A, 02_Master!G:G)), 0)

• Purpose: Dynamically pulls the current monthly spend from the Master table for a given line item ID and scales it by its specific annual growth rate, trapping lookup failures.

=SUMIFS(02_Master!F:F, 02_Master!B:B, "Engineering", 02_Master!I:I, "Active")

• Purpose: Aggregates total monthly spend strictly for active line items within the Engineering cost center.

=XIRR(05_Executive_Dashboard!C35:H35, 05_Executive_Dashboard!C34:H34)

• Purpose: Calculates the Internal Rate of Return (IRR) for irregular cash flow dates spanning the 5-year forecast horizon.

=INDEX(01_Inputs!$C$5:$G$20, MATCH(C$4, 01_Inputs!$B$5:$B$20, 0), MATCH($B$12, 01_Inputs!$C$4:$G$4, 0))

• Purpose: Two-dimensional array lookup fetching specific scaling assumptions based on Year and Scenario parameters.

=IF(ISBLANK(C10), "", C10 * (1 + $C$3))

• Purpose: Evaluates whether a preceding calculation cell is blank to keep report outputs clean; otherwise, applies a compounding inflation/growth factor.
