Excel Revenue Forecasting Model

I need a clean, well-structured Excel workbook that lets me plug in monthly revenue and expense figures and instantly see a forward-looking picture of the business. The sheet should run an automated trend analysis on the historical data, then use that trend to project future revenue, expenses, and overall cash flow for decision-making and scenario planning.

Core requirements
• One clearly labeled input area for raw revenue and expense numbers (ideally month-by-month).
• Dynamic charts and summary tables that display historical trends alongside the forecast.
• Transparent formulas and assumptions so I can tweak growth rates or time periods without breaking anything.
• All calculations kept within Excel—no external add-ins—so the file stays shareable across the team.

Deliverables
1. Unlocked .xlsx file with the complete model.
2. A short read-me tab explaining how to update data and adjust forecasting parameters.

If the structure leaves room to expand later into break-even or profit-margin analysis, even better, but the initial focus is accurate trend-based forecasting of revenue and expenses.
