Formulas Required

• Annual Payment (C2 in Amortization Sheet):
  =PMT(InterestRate/1, LoanTerm, -LoanAmount)
  This formula calculates the fixed annual payment using Excel’s PMT function.
• Principal Paid (D2):
  =C2 - E2
  Deducts interest from total payment to find principal portion.
• Interest Paid (E2):
  =B2 * InterestRate
  Computes interest based on the beginning balance and annual rate.
• Ending Balance (F2):
  =B2 - D2
  Subtracts principal paid from the beginning balance.
• Beginning Balance for Next Year:
  In row 3, Column B uses: =F2
• Total Interest (Loan Summary):
  Use a SUM function across all interest values in the amortization table.

Conditional Formatting

To enhance visual clarity and support administrative error detection:

• Highlight any negative ending balance in red with conditional formatting.
• Apply green fill to cells where principal paid exceeds $10,000 annually (for trend analysis).
• Use data bars for the "Annual Payment" column to visualize variation over time.
• Highlight empty or invalid inputs in yellow on the Loan Summary sheet with input validation rules.

User Instructions

Administrative users should follow these guidelines:

1. Enter loan amount, interest rate (as percentage), term in years, and start date in the Loan Summary sheet.
2. The system auto-populates the Annual Amortization Schedule.
3. Verify that all formulas are correctly calculated using Excel’s formula auditing tools.
4. Maintain a version history by saving dated copies (e.g., "LoanCalc_Apr2024.xlsx") for audit and compliance purposes.
5. Use the Data Validation & Instructions sheet to reference best practices and update inputs as needed.

Recommended Charts and Dashboards

• Bar Chart: Annual principal vs. interest paid (over time) to show decreasing interest share.
