Formulas Required

The template uses advanced Excel formulas for dynamic calculations:

• EMI Calculation (PMT function): =PMT(AnnualRate/4, TotalQuarters, -LoanAmount)
• Interest and Principal Breakdown:
  • Interest = Previous Balance × (AnnualRate / 4)
  • Principal = Payment – Interest
• Cash Flow After Loan: =Revenue - OperatingExpenses - LoanPayment
• Dynamically populated timeline: Uses DATE, EDATE, and TEXT functions to auto-generate quarters.

Conditional Formatting

To enhance usability and highlight critical data points:

• Negative Cash Flow (after loan): Red fill with white text, indicating financial strain.
• High Interest Payments: Yellow highlight if interest > 30% of total payment.
• Remaining Balance Below Threshold: Green text if balance drops below 25% of original loan amount.

2. Adjust grace period if needed (default is zero).
3. The “Quarterly Repayment Schedule” will auto-populate based on formulas.
