Data Types & Input Controls

• Month: Date or text (e.g., "January 2024") with dropdown validation for consistency.

• Profit Margin (%): Percentage format (e.g., 21.9%), automatically calculated using formulas.
• Input fields are color-coded with yellow fill for user entry, while calculated cells use gray or white background.

Essential Formulas Used

• Gross Profit = Sales Revenue – COGS: Automatically computed for each month.
• EBITDA = Gross Profit – Operating Expenses: Aggregates all operational costs including payroll, marketing, rent, and utilities.
• Earnings Before Tax (EBT) = EBITDA – Depreciation & Amortization.
• Tax Expense = EBT × Tax Rate (from Assumptions sheet): Links to the tax rate defined in the "Assumptions & Drivers" worksheet.
• Net Profit = EBT – Tax Expense.
• Profit Margin (%) = (Net Profit / Sales Revenue) × 100.
• VLOOKUP or INDEX-MATCH functions: Connect forecast data from the "Sales Forecasting Model" sheet to the income statement.

Conditional Formatting Rules

• Positive Net Profit (Green): Cells with net profit above zero turn green to highlight profitability.
• Negative Net Profit (Red): If forecasted net profit is negative, the cell turns red to indicate potential financial risk.
• Profit Margin Thresholds: Values below 15% are highlighted in orange; above 25% in light blue.
• Forecast vs. Actual Comparison (in Dashboard): Variance exceeding ±10% is marked with red or green shading for quick identification.
