Sheet Names
- Main Loan Calculator (Monthly): The primary interface where users input loan parameters and view the monthly amortization schedule.
- Cost Analysis Summary: A summary sheet showing total interest paid, principal paid, cumulative costs, and cost-efficiency metrics over the loan term.
- Payment Schedule (Amortization Table): A detailed breakdown of every monthly payment, showing how much goes toward interest and principal.
- Scenario Comparison: Enables users to test different loan amounts, interest rates, or terms to evaluate their impact on monthly costs and total expenses.

Table Structures
The core data structure is based on an amortization table that spans the entire loan term. Each table uses a consistent and scalable format to ensure clarity and reliability.
Main Loan Calculator (Monthly)
| Month | Opening Balance | Monthly Payment | Interest for Month | Principal Repayment | Closing Balance |
|---|---|---|---|---|---|
| 1 | =IF(A2="",0,B2) | =D2 | =C2*E2/100 | =D2-E2 | =B2-F2 |
| 2 | ...... |
The table starts at Month 1 and continues for the selected loan term (e.g., 36, 60, or 180 months). All values are dynamically calculated using Excel formulas.
Payment Schedule (Amortization Table)
This sheet provides a detailed list of all payments over time with additional columns:
- Month: Sequential month number
- Opening Balance: Balance at the start of the month
- Monthly Payment: Fixed or variable monthly amount (based on input)
- Interest Component (Monthly): Calculated as opening balance × monthly interest rate <24>
- Total Loan Amount: Input value (e.g., $100,000)
- Annual Interest Rate (%): User input (e.g., 5%)
- Loan Term (Months): Duration of the loan
- Total Payments Made (Monthly): Sum of all monthly payments over term
- Total Interest Paid: Total interest subtracted from principal over time
- Monthly Payment Breakdown (%): Percentage of each payment going to interest vs. principal
- Cost Control Index (CCI): A dynamic metric calculated as: (Total Interest / Loan Amount) × 100, indicating cost efficiency.
- Month: Integer (data type: number)
- Opening Balance: Currency (number with $ formatting)
- Monthly Payment: Currency, fixed or variable based on input options
- Interest for Month: Number (in dollars), calculated per month
- Principal Repayment: Number (dollars)
- Closing Balance: Currency, updated each month via formula chain
- Cost Control Metrics: Percentage or decimal values for efficiency analysis.
- MICROSOFT EXCEL MONTHLY INTEREST FORMULA: =Opening Balance * (AnnualRate / 12)
- PRINCIPAL REPAYMENT: =MonthlyPayment - InterestForMonth
- CLOSING BALANCE: =OpeningBalance - PrincipalRepayment
- TOTAL INTEREST PAID: =SUM(InterestColumn)
- COST CONTROL INDEX (CCI): =TOTAL_INTEREST_PAID / LOAN_AMOUNT
- DYNAMIC RANGE FOR SCHEDULE: Uses OFFSET or INDEX functions to auto-adjust for variable term lengths.
- MONTHLY PAYMENT CALCULATION (OPTIONAL): =PMT(annual_rate/12, n_periods, -loan_amount)
- Interest Component Highlight (Red): When interest exceeds 30% of total payment, highlighted in red to flag high-cost periods.
- Principal Repayment Growth (Green): As principal repayment increases over time, cells are shaded green to indicate progress toward payoff.
- Closing Balance Below $10k (Yellow): Alerts users when loan balance drops below a threshold, indicating nearing closure or potential early payoff.
- High Interest Rate Warning: If the annual interest rate exceeds 8%, the "Cost Control Index" is marked in bold red for immediate attention.

- Enter the following in cells: Loan Amount (cell B1), Annual Interest Rate (cell B2), and Loan Term in Months (cell B3).
- The amortization table will auto-populate starting from Month 1.
- Use the "Scenario Comparison" sheet to test alternative values—e.g., higher interest rate or shorter term—and observe cost implications.
- Review the "Cost Analysis Summary" for key performance indicators like total interest paid and CCI.
- Apply conditional formatting by selecting ranges and using “Format Cells” → “Conditional Formatting” to set thresholds.
