Table Structures and Columns

The core tables in this template are designed for readability and consistency across team use:

1. Input Parameters (Sheet Name)

• Loan Principal (Currency): The initial amount borrowed (e.g., $50,000). Data type: Number (Currency).

• Loan Term (Months): Duration of the loan in months. Data type: Integer.
• Payment Frequency: Select between Monthly, Bi-Weekly, or Quarterly. Data type: Dropdown list.

• User/Team Member (Text): Field to log who last updated or reviewed the data.

2. Loan Summary (Sheet Name)

• Loan ID: Auto-generated unique identifier (e.g., L-2024-001).
• Total Payments (Currency): Sum of all monthly payments over the term.
<3>Total Interest Paid (Currency): Calculated interest component across the loan duration.
• Monthly Payment (Currency): Fixed value derived from formula.
• Final Balance (Currency): Should be zero upon completion of the term.
• Payoff Date: Final due date based on term and start date.

3. Amortization Schedule (Sheet Name)

This table spans over the loan term in monthly rows and includes:

• Month: Sequential month number (1 to N).
• Date: Full date of payment.
• Payment Amount (Currency): Fixed monthly amount.
• Interest Portion (Currency): Interest due for the month.
• Principal Portion (Currency): Principal reduction in that month.
• Remaining Balance (Currency): Updated balance after payment.

Formulas Required

The template relies on standard financial formulas:

• =PMT(rate/12, term_months, -principal): Calculates monthly payment based on rate and term.
• =IPMT(rate/12, month_number, term_months, -principal): Returns interest portion for a specific month.
• =PPMT(rate/12, month_number, term_months, -principal): Returns principal portion for a specific month.
• =IF(E2="", "Missing Input", "Valid"): Data validation feedback.
• =DATE(start_date_year, start_date_month + (month_number -1), 1): Dynamically generates payment dates.

Conditional Formatting

• Red highlight on the "Monthly Payment" when the interest rate exceeds 10% to alert high-cost loans.
• Green highlight on all rows in the Amortization Schedule when principal portion increases (indicating repayment progress).
• Yellow background for any month where interest portion exceeds 50% of payment—indicative of a slow principal reduction.
• Bold formatting on the "Final Balance" in the Loan Summary if it does not equal zero (error flag).

Instructions for the User

This template is intended to be used collaboratively across departments such as finance, operations, and risk management. Users should:

• Enter loan details in the "Input Parameters" sheet.
• Select payment frequency using dropdowns (ensure consistency).
• Use the "Team Notes & Comments" section to log changes or approvals—assign specific team members to each update.
