Table Structures & Columns

Cash Flow Projection Table (Main Sheet)

Data Types: All columns use "Currency" format (e.g., $#,##0.00) for consistency and accuracy. The "Month" column uses date formatting to support automatic sequencing.

Formulas Required

• Closing Cash Balance: = Opening Cash Balance + Total Inflows – Total Outflows
• Monthly Growth Rate (Revenue): = Previous Month's Revenue × (1 + Growth Rate Input from Assumptions Sheet)
• Total Inflows: = SUM(Inflows, Other Inflows)
• Total Outflows: = SUM(Outflows, Loan Repayments, Tax Payments)
• Cumulative Cash Balance (Dashboard): Use a running total formula to track financial health over time.

Conditional Formatting

To enhance visual understanding and quickly identify risks or opportunities:

• Negative Closing Balance: Red fill with white text to highlight potential cash shortages.
• Cash Balance Above $15,000: Green background indicating strong liquidity.
• Revenue Growth Rate > 15% Month-over-Month: Yellow highlight to signal rapid expansion.
• Last 3 Months with Negative Cash Flow: Flashing red border to trigger alert for intervention.

User Instructions

1. Navigate to the "Cash Flow Assumptions" sheet and input your projected growth rate, average customer value, payment terms (e.g., Net 30), and initial startup funding.
2. In the "Revenue Forecast" sheet, break down expected sales by product/service line. Use historical data or market research if available.
3. Enter all recurring and one-time expenses in the "Expense Tracker." Classify each cost (e.g., Rent, Salaries, Marketing).
4. Return to the "Cash Flow Projection" sheet—the template will auto-populate based on your inputs.
5. Use the "Scenario Analysis" sheet to model different futures: e.g., a 20% slower growth scenario or early customer churn.
6. Review the Dashboard for visual indicators of cash health and adjust business plans accordingly (e.g., delay hiring, seek funding).

Example Rows

The template includes three fully populated example rows (January–March 2025) to demonstrate realistic startup cash flow patterns. These reflect common startup behaviors: lower initial revenue, rising expenses due to product launch and marketing, followed by improving margins.
