Table Structures and Columns

Sheet 2: Monthly Budget & Forecast – Main Table Structure

This sheet contains a primary table with the following columns:

• Month (Date): Data Type: Date (e.g., January 1, 2025). Ensures chronological order and supports date-based formulas.
• Category: Data Type: Text. Lists expense or revenue categories such as "Salaries," "Marketing," "Software Subscriptions," or "Product Sales."
• Budgeted Amount: Data Type: Currency (USD). The planned amount for each category per month.
• Actual Amount: Data Type: Currency. Where real-world spending or income is recorded monthly.
• Variance (Budget - Actual): Data Type: Currency. Automatically calculates the difference between budgeted and actual figures.
• Variance %: Data Type: Percentage. Formula = (Variance / Budgeted Amount) * 100. Highlights over/under performance.

Sheet 4: Revenue Projections Table

Columns include:

• Month: Date field aligned with the main budget sheet.
• Revenue Source: Text (e.g., "Monthly Subscriptions," "One-Time Sales," "Grants").
• Forecasted Revenue: Currency.
• Actual Revenue: Currency (to be updated monthly).
• Growth Rate (%): Formula-driven field showing month-over-month change.

Formulas Required

The template uses a combination of Excel functions to automate calculations and provide real-time feedback:

• =SUMIF(Category_Column, "Salaries", Budgeted_Amount_Column): Totals all salaries budgeted across months.
• =IF(Actual < Budget, "Under", IF(Actual = Budget, "On Target", "Over")): Dynamic status indicator for performance tracking.
• =VLOOKUP(Month, Assumptions_Table, 2, FALSE): Pulls inflation or growth multipliers from the Settings sheet.
• =ROUND((Actual - Budget) / Budget * 100, 1): Calculates precise variance percentage with one decimal place.
• =SUM(Actual_Amount_Column) - SUM(Budgeted_Amount_Column): Net cash flow difference per month.

Conditional Formatting

To improve visual clarity and quick decision-making:

• Variance (Budget - Actual):
  • Red text + background: If negative (overspent).
  • Green text + background: If positive (under budget).
  • Amber: Variance within ±5% of target.
• Variance %:
  • Red: >10% variance (over budget).
  • Green: < -10% variance (under budget).
  • Yellow: Between -10% and +10%.
• Cash Flow Trend: Color scales applied to monthly net cash flow data, using red-to-green gradients to indicate financial health trends.
