Formulas Required

• Monthly Payment (PMT function):
  =PMT(interest_rate/months_per_year, total_payments, -loan_amount)
  Example: =PMT(0.045/12, 360, -300000) → $1,529.78
• Principal Portion (PPMT function):
  =PPMT(rate, period, nper, pv)
• Interest Portion (IPMT function):
  =IPMT(rate, period, nper, pv)
• Cumulative Interest: Use SUM() over interest columns for a running total.
• Total Repayment Cost: Monthly Payment × Number of Payments
• Interest-to-Principal Ratio: (Total Interest / Total Paid) → use conditional logic to flag high ratios

Conditional Formatting Features

• Cash Flow Health Indicators: Highlight months where interest exceeds principal in red; when principal dominates, highlight green.
• Payment Delinquency Warnings: If current month is past due or upcoming payment date is within 10 days, apply orange background.
• Trend Analysis in Dashboard: Color-scale gradient for cumulative interest to visually show acceleration over time.
• Scenario Comparison: Use data bars in the Scenario Analysis table to compare monthly payments at a glance.
