TABLE STRUCTURES AND COLUMNS

1. Loan Summary Sheet

This structure ensures that Administrative Support staff can easily verify calculations, spot discrepancies, and generate accurate reports with minimal effort.

FORMULAS REQUIRED

• Monthly Payment (PMT):
  =PMT(AnnualInterestRate/12, LoanTermMonths, -LoanAmount)
  This formula calculates the fixed monthly payment using Excel's built-in PMT function.
• Monthly Interest Portion:
  =RemainingBalance * (AnnualInterestRate/12)
  Calculates the interest component for each month based on the outstanding balance.
• Principal Portion:
  =MonthlyPayment - MonthlyInterestPortion
  Determines how much of the payment reduces the principal.
• Remaining Balance:
  =PreviousRemainingBalance - PrincipalPortion
  Updates the outstanding balance after each payment.
• Cumulative Payments:
  =SUM($D$2:D2) (for cumulative principal and interest)
  Used to track total amounts paid over time.

CONDITIONAL FORMATTING

To enhance readability and improve data integrity, the template uses the following conditional formatting rules:

• Highlight Overdue Payments: If a payment is not marked as "Paid" in the Payment Tracking Log, cells turn red to flag outstanding obligations.
• Balance Tiers: Remaining balance cells are color-coded: green (low risk), yellow (medium risk), and red (high risk or negative).
• Monthly Payment Alerts: Any monthly payment amount that exceeds a pre-set budget threshold is highlighted in orange.
