Data Types and Formulas

This template uses dynamic formulas to ensure real-time calculations. All formulas are designed for accuracy and audit traceability:

• Payment Amount (Loan Details Sheet): =-PMT(E5/12, F5*12, D5) (for monthly payments; adjusted if frequency differs).
• Periodic Interest Rate: =E5 / 12 for monthly, or =E5 / 4 for quarterly.
• Payment Date (Amortization Sheet): =EDATE(H5, (A6-1)*IF(G5="Monthly",1,IF(G5="Quarterly",3,IF(G5="Bi-Annual",6,12))).
• Remaining Balance (Amortization Sheet): =F5 - SUMIFS(E:E, A:A, "<" & A6) for accurate cumulative principal reduction.
• Interest Portion: =F6 * (E5 / 12).

The template includes error-checking with =IFERROR(..., "Error") around all key calculations for stability during audits.

Conditional Formatting Rules

To support risk identification and visual audit readiness:

• Red Highlight: Any loan where the interest rate exceeds 10% (high-risk indicator).
• Yellow Highlight: Payments due within the next 30 days.
• Green Highlight: Loans with status “Active” and fully compliant with amortization schedule.
• Data Bars: Applied to the "Remaining Balance" column to visually track outstanding debt levels.
