Sheet Names & Purpose

Table Structures & Data Flow

The Income Statement (Current Period) sheet uses a structured table format starting at cell A5. The table is designed as a hierarchical income statement with five levels:

1. Revenue Section: Subtotals and line items for sales, service fees, and other revenue streams.
2. Cost of Goods Sold (COGS): Direct costs attributable to producing goods or services.
3. Gross Profit: Calculated as Revenue minus COGS.
4. Operating Expenses: Includes salaries, rent, utilities, marketing, and administrative costs.
5. Net Profit (Loss): Final profitability metric after all expenses are accounted for.

Columns & Data Types

All columns are protected except for the "This Period Amount" and "Status" fields to prevent accidental formula errors. Data types are enforced via Excel’s Data Validation tools.

Formulas Required

• Gross Profit: =SUMIF(Category, "Revenue", This Period Amount) - SUMIF(Category, "COGS*", This Period Amount)
• Total Operating Expenses: =SUMIF(Category, "Operating Expenses*", This Period Amount)
• Net Profit: = Gross Profit - Total Operating Expenses
• Change (%): =(This Period Amount - Last Year Amount) / ABS(Last Year Amount)
• Status Indicator: Uses IF statement to flag incomplete entries: =IF(ISBLANK(This Period Amount), "Needs Input", "Validated")

Conditional Formatting

To enhance visual clarity and alert users to critical issues, the following conditional formatting rules are applied:

• Negative Net Profit: Red background with white text (alerts user to potential losses).
• Change (%) > 10% or < -10%: Yellow highlight to flag significant fluctuations for review.
• Status = "Needs Input": Orange fill with bold font—immediately draws attention to incomplete entries.
• Gross Profit Margin < 25%: Light red tint on the row, indicating potentially unsustainable cost structure.
