Key Formulas Used

• =FORECAST.LINEAR(A4, B:B, A:A) – Predicts future sales volume using linear regression.
• =PMT($D$3/12, $D$4*12, -$E$3) – Calculates monthly loan payment (assumes annual rate and term).
• =IPMT($D$3/12, A8, $D$4*12, -$E$3) – Returns interest portion for a specific payment period.
• =PPMT($D$3/12, A8, $D$4*12, -$E$3) – Returns principal portion of payment.
• =IF(C6 > D6, "Over Budget", "On Track") – Conditional status check for revenue vs loan payment.

Conditional Formatting Rules

• Sales Forecast vs Loan Payment: If predicted revenue is less than the required monthly payment, the cell turns red. If it exceeds, it turns green.
• High Interest Risk: Highlight cells where interest portion exceeds 40% of total payment (in amber).
• Trend Lines: Conditional formatting applied to growth rate columns: >5% = bright green; <0% = red.
• Dashboards: Use icon sets (traffic lights) for performance indicators in the dashboard sheet.

User Instructions

1. Enter historical sales and loan data in the "RawData" sheet. Ensure dates are consistent (e.g., first day of each month).
2. Adjust assumptions in the "Assumptions & Settings" sheet—set interest rate, forecast period length, and growth factor.
3. Review the "Forecasting Engine" tab for auto-generated sales projections. Modify seasonality factors manually if needed.
4. The "Amortization" tab will automatically calculate payments based on loan terms defined in assumptions.
5. Use the "Scenario Manager" to compare different combinations: e.g., 10% higher sales vs. 1% higher interest rate.
6. Interact with charts on the "Dashboard & Visuals" sheet—hover over points for detailed values, filter by time period.
