Excel Template Description: Audit Preparation – Loan Calculator (Analysis View)

This comprehensive Excel template is specifically designed for financial professionals and internal audit teams involved in loan portfolio reviews, risk assessments, and compliance verification. The primary purpose of this template is Audit Preparation, ensuring that all critical aspects of a loan’s financial behavior are documented, calculated accurately, and visualized effectively to support audit evidence collection. It combines the functionality of a dynamic Loan Calculator with an analytical framework in Analysis View, enabling auditors to validate loan terms, assess repayment feasibility, identify discrepancies, and generate audit-ready reports efficiently.

Schedule Overview: Sheet Names

The template consists of six main sheets designed for seamless navigation and robust data management:

1. Loan Inputs: Entry point for all loan details (principal, rate, term, etc.). Used as a source for calculations.
2. Amortization Schedule: Detailed monthly breakdown of principal and interest payments over the life of the loan.
3. Analysis View: Central dashboard showing key metrics, comparison tables, risk indicators, and audit flags. This is the primary interface for auditors.
4. Audit Trail & Notes: A secure log for documenting audit observations, changes made during review, responsible personnel, and supporting evidence references.
5. Summary Statistics: High-level KPIs including total interest paid, average monthly payment, loan-to-value ratio (LTV), and amortization period.
6. Charts & Dashboards: Visual representations of data trends, payment distributions, and risk exposure patterns.

Table Structures and Columns (Analysis View)

The Analysis View sheet contains five distinct tables, each serving a critical function in the audit process:

1. Loan Comparison Table
   This table compares multiple loans side-by-side for consistency checks. Columns include:
   • Loan ID (Text)
   • Effective Rate (%) (Decimal)
   • Term in Months (Integer)
   • Original Principal ($/Currency) (Number, 2 decimal places)
   • Monthly Payment ($/Currency) (Number, 2 decimals)
   • Benchmark Payment ($/Currency) (Number, 2 decimals)
   • Discrepancy Flag (Text – "Match" / "Mismatch")
2. Payment Performance Tracker
   Monitors actual payments versus scheduled payments to detect delinquency trends.
   • Month (Integer)
   • Scheduled Payment ($/Currency) (Number, 2 decimals)
   • Actual Payment ($/Currency) (Number, 2 decimals)
   • Payment Status (Text – "On Time", "Late", "Missed")
   • Difference ($/Currency) (Number, 2 decimals)
3. Risk Exposure Indicators
   Assesses potential risk factors associated with the loan.
   • Indicator (Text)
   • Threshold Value (Number or %)
   • Current Value (Number or %)
   • Status (Text – "Within Limit", "Warning", "Critical")
4. Audit Compliance Flags
   Highlights potential audit findings.
   • Issue Description (Text)
   • Severity Level (Text – Low / Medium / High)
   • Status (Text – Open / Resolved)
   • Reference to Documentation (Hyperlink to Audit Trail sheet)
5. Interest Rate Trend Analysis
   Compares variable interest rate movements over time against the agreed terms.
   • Period Start Date (Date)
   • Effective Rate (%) (Decimal)
   • Contracted Rate (%) (Decimal)
   • Difference (%)

Data Types and Formulas

All columns use appropriate data types for accuracy and validation:

• Text fields (Loan ID, Issue Description) are protected with data validation to prevent incorrect entries.
• Numbers use currency formatting with two decimal places.
• Dates are validated using Excel’s DATE function and input masks.

Key Formulas:

• Monthly Payment (Loan Inputs sheet):
  =PMT(Effective_Rate/12, Term_Months, -Principal)
• Discrepancy Flag (Analysis View – Loan Comparison Table):
  =IF(ABS(Monthly_Payment - Benchmark_Payment) <= 0.01, "Match", "Mismatch")
• Payment Status (Payment Performance Tracker):
  =IF(Actual_Payment >= Scheduled_Payment, "On Time", IF(Actual_Payment = 0, "Missed", "Late"))
• Difference in Payment (Analysis View):
  =Actual_Payment - Scheduled_Payment
• Risk Indicator Status:
  =IF(Current_Value <= Threshold_Value, "Within Limit", IF(Current_Value > 1.2*Threshold_Value, "Critical", "Warning"))
• Interest Rate Difference:
  =Effective_Rate - Contracted_Rate

Conditional Formatting for Audit Readability

To enhance visual audit readiness, the following formatting rules are applied across the Analysis View:

• Mismatch flags: Red fill with white text.
• Missed or Late payments: Orange background for "Late", red for "Missed".
• Critical risk indicators: Solid red border and bold font.
• High-severity audit issues: Highlight with dark yellow fill.
• Negative differences in payments or rates: Red text for negative values.

User Instructions

6. Update the Compliance Flags and Risk Indicators as needed.
7. Use the Charts & Dashboards sheet to generate visuals for audit presentations.
8. To prepare for audit, export the Analysis View and Audit Trail to PDF or print as evidence package.
