The template is built with clean, modern design principles suitable for high-growth startups operating in competitive markets.

Sheet Names & Purpose

1. Loan Summary Dashboard: The central hub displaying key metrics, repayment timeline, total interest paid, and ROI forecasts.
2. Marketing Spend Plan: A detailed table outlining monthly marketing activities with associated costs and expected KPIs.
3. Loan Calculator & Amortization Schedule: Core financial engine that computes loan payments, interest, principal reduction, and balance over time.
4. ROI & Forecasting Model: Dynamic model linking marketing spend to customer acquisition cost (CAC), lifetime value (LTV), and projected revenue growth.
5. Scenario Analysis: Predefined sheets to compare different funding levels, interest rates, and repayment terms.

Table Structures & Columns

1. Marketing Spend Plan (Sheet: Marketing Spend Plan)

This table tracks planned marketing expenditures month by month across different channels.

2. Loan Calculator & Amortization Schedule (Sheet: Loan Calculator)

This table models loan amortization with monthly payments, principal/interest breakdowns, and cumulative totals.

Data Types & Formulas Required

• Month (Text/Date): "January 2025" or date format for timeline consistency.
• Budget Allocation ($): Currency type with two decimal places.
• Expected Leads (Number): Integer or whole number (e.g., 1,200).
• Conversion Rate (%): Percentage format between 0% and 100%.
• CAC ($): Currency calculated using: =Budget / (Expected Leads × Conversion Rate / 100).
• Loan Payment: Formula using Excel’s PMT function: =PMT(annual_rate/12, total_months, -loan_amount)
• Principal & Interest: Use PPMT and IPMT functions respectively for amortization.
• Total Marketing Cost (Monthly): SUM of budget allocations per month.
• Cumulative Loan Balance: Recursive formula or use running sum from prior balance minus principal paid.

Conditional Formatting & Visual Indicators

• CAC Alert: If CAC exceeds $150, highlight cell in red (e.g., apply rule: =C15 > 150) to flag high acquisition costs.
• Loan Payment Status: Highlight overdue payments in yellow if current month exceeds payment due date.
• ROI Forecast: Use data bars to visualize monthly ROI trend from the Forecasting Model sheet.
• Critical Thresholds: Color-code cells where LTV/CAC ratio drops below 3x—indicating unprofitable acquisition.
