Table Structures and Data Types (Loan Details & Schedules Sheet)

The primary working sheet contains a structured table with the following columns and data types:

Key Formulas Required

The following formulas are embedded across the sheets to ensure automated accuracy and audit readiness:

• Monthly Payment Calculation (PMT):
  =PMT(Effective_Rate/12, Term_Months, -Original_Amount)
  Calculates the fixed monthly installment based on principal, rate, and term.
• Interest Accrual Per Month:
  =ROUND(Balance * (Effective_Rate/12), 2)
  Applies compound interest monthly and rounds to two decimal places for currency accuracy.
• Remaining Balance (Amortization):
  =Previous_Balance + Interest_Accrued - Principal_Payment
  Maintains a running balance with correct principal reduction.
• Status Validation:
  =IF(AND(Due_Date <= TODAY(), Balance > 0), "In Arrears", IF(Balance = 0, "Paid in Full", "Active"))
  Automatically updates status based on current date and balance.
• Loan ID Auto-Generation:
  =IF(ROW()-1=1,"LOAN"&TEXT(COUNTA(A:A),"000"), "")
  Assigns a unique, sequential loan identifier starting from LOAN001.

Conditional Formatting Rules

To enhance audit visibility and highlight potential risks, the template includes:

• Red Highlighting: For any loan with a status of "In Arrears" or if the payment due date is within 7 days.
• Yellow Background: For loans where the effective interest rate exceeds 10% (configurable threshold).
• Green Border: On fully paid loans to indicate closed status.
• Data Bars: In the "Remaining Balance" column to visually compare loan sizes across entities.
