Table Structures & Data Types

The template uses a normalized table structure to ensure data integrity and ease of maintenance across departments. Each sheet contains clearly defined tables with standardized data types:

1. Loan Inputs Sheet

2. Amortization Schedule Sheet

Formulas Required

• Monthly Interest Rate: =B2/12/100 (e.g., 6% annual rate → 0.5%)
• Monthly Payment: =PMT(B3/12, B4, -B1) — calculates fixed payment.
• Remaining Balance: =IF(C2=0, 0, (Previous Balance - Principal) * (1 + Interest Rate))
• Sensitivity Analysis: Uses dynamic tables with IF and VLOOKUP to test rate/term changes.
• Workflow Status Update: Conditional logic updates status based on date thresholds or manual inputs.

Conditional Formatting

• Red Highlight: If monthly payment exceeds 15% of gross monthly revenue (calculated in another sheet).
• Yellow Highlight: If loan term exceeds 72 months or interest rate > 10%.
• Green Checkmark: When all required fields are filled and the status is "Approved".
• Color Scale: Applied to the "Remaining Balance" column to visualize repayment progress (from green to red).
• Data Validation: Ensures inputs like interest rate remain between 0–20%, and term between 12–360 months.

Instructions for the User

1. Open the template and navigate to the "Loan Inputs" sheet.
2. Enter all loan parameters: amount, interest rate, term, down payment, and frequency.
3. Select a workflow status from the dropdown to begin tracking approval progress.
4. The amortization schedule will automatically update based on input values.
5. Use the "Sensitivity Analysis" sheet to test different interest rates or loan terms by adjusting variables.
6. Review the dashboard for visual summaries of key metrics such as total cost, monthly burden, and repayment timeline.
7. When all steps are complete, export financial reports via "Financial Reports" sheet for executive review or audit purposes.
