Table Structures and Data Types

Budget Overview Sheet (Summary Dashboard)

This sheet provides a snapshot of the startup’s financial health. It includes:

Monthly Budget Detail Sheet

This sheet is the core of the template, structured to capture all startup-related financial activity. Data types include:

• Category (Text): e.g., Salaries, Marketing, Software Subscriptions, Rent

• Actual Spending (Currency): Real-time tracking of expenses incurred
• Variance (Currency & %): Difference between budget and actual, displayed in absolute and percentage terms
• Notes (Text): Optional field for comments on variances or project updates

Formulas and Automation

The template leverages advanced Excel formulas to automate tracking and forecasting:

• =SUMIF(CategoryRange, "Salaries", AmountRange) – aggregates expenses by category.
• =VLOOKUP(Month, ForecastTable, 2, FALSE) – pulls monthly revenue projections.
• =IF(Variance <= 0, "Under Budget", "Over Budget") – categorizes variances.
• =SUM(CashInflows) - SUM(CashOutflows) – calculates net monthly cash flow on the Cash Flow Forecast sheet.
• =FORECAST.LINEAR(TODAY(), KnownYs, KnownXs) – predicts future revenue trends based on historical data.

Conditional Formatting

To improve visual clarity and highlight anomalies, the following rules are applied:

• Red fill with white text: Variance greater than 15% over budget.
• Green fill with white text: Variance less than -10% under budget (positive performance).
• Yellow highlight: Total expenses exceeding 90% of the monthly budget.
• Conditional icons (traffic light): Visual indicators for variance status in summary dashboard.
