4. Summary & Metrics: Provides key performance indicators (KPIs) such as total interest paid, effective cost of borrowing, and equity accumulation.
5. Dashboard: A visual summary with charts and dynamic filters to support decision-making.

Table Structures and Column Definitions

All tables are designed for clarity, consistency, and scalability. Data types are explicitly defined to maintain accuracy:

1. Loan Input & Parameters Sheet

2. Monthly Payment Schedule Sheet

Formulas Required

The template leverages Excel’s powerful formula engine to deliver accurate and real-time results:

• Mortgage Payment Formula: =PMT(rate/12, nper*12, -loan_amount) to calculate monthly payment.
• Amortization Table (Monthly): Uses nested formulas for interest and principal portions via: Interest = Opening Balance * (rate/12); Principal = Total Payment – Interest; Closing Balance = Opening Balance – Principal.
• Interest Paid Summary: SUM of all interest payments across the term.
• Total Cost of Loan: Loan Amount + Total Interest Paid.
• Effective Annual Rate (EAR): =EFFECT(annual_rate, 1) to reflect compounding effects.
• Break-even Point: Calculates when the total interest paid equals a specified threshold via VLOOKUP and IF logic.

Conditional Formatting

To improve data readability and user awareness, several conditional formatting rules are applied:

• Red highlight for monthly payments exceeding 10% of monthly income (user-defined threshold).
• Green background when the total interest paid is below 30% of the loan amount.
• Yellow alert if payment frequency exceeds standard (e.g., bi-annual with low term).
• Data bars on principal payments to show progression over time.
