Sheet Names

• Loan Input: Central input sheet where users define all key variables of the loan.
• Amortization Schedule: Detailed table showing monthly payments, interest, principal, and remaining balance over time.
• Cost Summary: A compact summary sheet highlighting total interest paid, total repayment amount, and cost efficiency metrics.
• Scenario Analysis: A dedicated tab to compare multiple loan options (e.g., different interest rates or terms) side-by-side.
• Dashboard: An interactive visual summary with charts and key performance indicators (KPIs) for cost control monitoring.

Table Structures & Data Types

The core structure is built around three primary tables, each designed for clarity and efficient data handling:

1. Loan Input Sheet

2. Amortization Schedule

3. Cost Summary Sheet

Formulas Required

• PMT(): Calculates monthly payment based on interest rate, term, and principal: =PMT(B2/12, B3*12, -B1)
• IPMT(): Returns interest portion of a given payment period.
• PPMT(): Returns principal portion of a payment.
• IF() and AND() functions: Used to flag high-interest scenarios or cost control alerts (e.g., if interest rate > 6%, trigger warning).
• SUMIFS(): Aggregates total interest paid across different loan types or time periods.
• ROUND(): Formats values to two decimal places for currency display.

Conditional Formatting

• Interest Rate Highlighting: If rate exceeds 6%, background turns red; otherwise green.
• Total Interest Alert: If total interest > 30% of principal, applies yellow highlight with warning icon.
• Cash Flow Warning: If monthly payment exceeds 30% of income, cell turns orange and displays "High Risk".
• Cost Control Status: Automatically fills status (e.g., “Low Risk”, “Medium”, “High”) based on pre-defined thresholds.
