Sheet Names

• Loan Inputs: Central sheet where all loan parameters are defined.
• Amortization Schedule: Detailed breakdown of payments over time, including principal and interest.
• Data Log: A historical tracking sheet for auditability and performance review.
• Summary Dashboard: A high-level view showing key financial KPIs such as total cost, equity ratio, and repayment timeline.

• Validation Rules: Contains data validation lists and error-checking criteria.

Table Structures & Column Definitions

The template uses a relational, tabular design to ensure clarity and consistency across sheets. All tables are structured with explicit column names, data types, and descriptions.

1. Loan Inputs (Sheet: Loan Inputs)

2. Amortization Schedule (Sheet: Amortization Schedule)

Formulas Required

All calculations are dynamically driven by built-in Excel functions, ensuring accuracy and real-time updates:

• MIDTERM(Loan Amount, Rate, Term): Calculates monthly payment using =PMT(rate/12, term*12, -loan_amount).
• Interest Portion: Uses =IPMT(rate/12, period, term*12, loan_amount).
• Principal Portion: Uses =PPMT(rate/12, period, term*12, loan_amount).
• Remaining Balance: Uses cumulative principal reduction via a running sum or recursive formula.
• Status Flag: Compares payment date against today’s date using IF(AND(date > TODAY(), ...), "On-Time", "Late")).
• Total Interest Cost: Sum of all interest components over the loan term.

Conditional Formatting Rules

• Rows in Amortization Schedule where the balance drops below 5% of original loan amount will be highlighted in green.
• If any payment is marked “Late” for more than 30 days, the row turns red with a warning flag.
• Cells containing negative values (e.g., interest or principal) are highlighted in yellow to prevent errors.
• The Summary Dashboard uses conditional formatting to show trends: green for improvement, red for deterioration.
