Formulas Required

  Calculates monthly (or periodic) payment based on rate, term, and principal.

  =PPMT(annual_rate/periods_per_year, period_number, total_periods, -loan_amount)
  Extracts the principal portion of each payment.

  Ensure clean error handling in case of invalid inputs.

Conditional Formatting

To support Administrative Support tasks, the template includes visual cues through conditional formatting:

• Past Due Payments: If the "Payment Date" is earlier than today and payment status is not marked as "Paid", cells turn red with a bold font.
• High Interest Payments: Any interest amount exceeding 30% of the total payment is highlighted in orange.
• Low Remaining Balance: If balance drops below 10% of original loan, cell background turns yellow for early warning.
• Data Validation Alerts: Red borders appear around cells with invalid or missing input (e.g., negative values).
