Key Formulas Required

• Monthly Payment (PMT):
    =PMT(InterestRate/12, TermMonths, -LoanAmount)
  Used in both Summary Dashboard and Amortization Schedule.
• Interest Portion per Period:
    =RemainingBalance × (AnnualRate / 12)
• Principal Portion:
    =MonthlyPayment - InterestPortion
• Remaining Balance:
    =PreviousBalance - PrincipalPortion
• Cumulative Cash Balance (Cash Flow Sheet):
    =PreviousCumulative + NetCashFlow
• Conditional Formatting Trigger for Negative Cash Flow:
    =tblCashFlow[[#All],[Cumulative Cash Balance]] < 0
• Total Interest Paid (Scenario Sheet):
    =(MonthlyPayment × TermMonths) - LoanAmount

Conditional Formatting Rules

• Negative Cash Balance: Highlight in red with bold text to warn of potential cash shortfall.
• High Interest Rate (>7%): Yellow highlight to flag potentially risky terms.
• Last Payment Row (Amortization): Green background and "Final Payment" label for visual clarity.
• Monthly Payment Exceeds 30% of Forecast Revenue: Orange font to indicate high debt burden relative to income.
