Ssheet Names and Structure

The template includes the following sheets, each serving a specific purpose within the team workflow:

• Loan Calculator (Main): Central sheet containing all input fields, calculations, and output tables.
• Team Inputs & Feedback: A shared workspace where team members can log loan parameters, comments, or adjustments with timestamps and names.
• Summary Dashboard: An overview of key financial metrics (monthly payment, total interest, amortization schedule) displayed in a clean dashboard format.
• Amortization Schedule: A detailed table showing month-by-month breakdown of principal and interest payments over the loan term.
• Team Collaboration Log: Tracks changes made to the model, with user names, dates, and reasons for modifications—enabling full auditability.
• Formula Reference & Instructions: A dedicated sheet explaining all formulas used and providing step-by-step guidance for users.

Table Structures and Column Definitions

The core Loan Calculator (Main) sheet contains the following data tables:

• Input Parameters Table: Contains dynamic inputs such as loan amount, interest rate, term (in months), down payment, and repayment frequency.
• Output Results Table: Automatically populates with calculated values including monthly payment, total interest paid, total repayment amount, and final balance.
• Amortization Schedule Table: A structured table with columns for month number, beginning balance, principal payment, interest payment, ending balance.

Each column is defined with precise data types:

• Loan Amount: Decimal (numeric), required input.
• Interest Rate (%): Decimal (numeric), formatted as percentage (e.g., 5.0%).
• Term (months): Integer, validated to be ≥12.
• Down Payment: Decimal, must not exceed loan amount.
• Monthly Payment: Auto-calculated numeric value.
• Total Interest Paid: Auto-calculated sum of interest components over the term.
• Amortization Periods: Integer, derived from term input.

Formulas Required

The template leverages Excel’s powerful built-in functions for accuracy and efficiency:

• =PMT(rate, nper, pv): Calculates the monthly payment based on interest rate, number of periods, and present value.
• =IPMT(rate, per, nper, pv): Computes interest paid in a specific period (used in amortization).
• =PPMT(rate, per, nper, pv): Calculates principal portion of a payment for each month.
• =SUM() and =ROUND() are used to aggregate totals and maintain precision.
• Validation Formulas: Input ranges are validated using Data Validation rules (e.g., "Loan Amount" must be >0).

Conditional Formatting Rules

To support team collaboration and enhance readability, the template includes several conditional formatting features:

• Highlight Monthly Payment Over $1,000: Any monthly payment exceeding $1,000 turns yellow to signal high cost.
• Interest Rate Threshold Highlighting: Rates above 7% turn red to alert users of high-cost loans.
• Red Flag for Negative Down Payment: If down payment exceeds loan amount, the cell turns red with a warning message.
• Amortization Balance Progress Tracking: The balance decreases over time—shown with green gradient fill from high to low.
• Team Feedback Highlighting: Cells in the collaboration log are color-coded by status (e.g., "Approved," "Under Review," "Rejected").
