There is only one sheet in this template—LoanData_Calculator. The single-page layout ensures simplicity and ease of navigation. All data inputs, calculations, visualizations (charts), and conditional formatting are seamlessly integrated into a unified interface.

Table Structure and Layout

The worksheet is divided into four primary sections:

1. Borrower & Loan Information Input Zone
2. Loan Calculation Engine
3. Data Collection Dashboard (Summary Metrics)
4. Optional: Historical Data Log Table (for tracking multiple applications)

Columns and Data Types

Formulas Required

The following formulas are implemented for accurate, dynamic calculations:

• Monthly Payment (A6): =PMT(B4/12, B5*12, -B3)
  Where B3 = Loan Amount, B4 = Annual Interest Rate (as decimal), B5 = Term in Years.
• Total Repayment (A7): =A6 * (B5 * 12)
  Multiplies monthly payment by total number of months.
• Total Interest Paid (A8): =A7 - B3
  Difference between total repayment and principal amount.
• Loan ID Auto-generation (A1): =IF(ROW()-ROW($A$1)=0, "LOAN" & TEXT(COUNTA($A$2:$A$20)+1,"000"), "")
  Generates sequential IDs based on existing entries.
• Application Date (A9): =TODAY()
  Automatically populates today’s date upon entry.

Conditional Formatting

To enhance usability and data integrity, the following conditional formatting rules are applied:

• Borrower Name (A2): If blank, highlight cell in red to prompt input.
• Loan Amount (A3): If negative or zero, display in yellow warning text.
• Status Column (A10):
  • "Pending" → Yellow fill with black text
  • "Approved" → Green fill with white text
  • "Rejected" → Red fill with white text
• Monthly Payment (A6): If greater than $10,000, highlight in blue to flag high-value loans.
• Total Interest Paid (A8): If exceeding 50% of the principal amount, trigger a red border to alert potential risk.

• Bar Chart (Below Table): "Monthly Payment Distribution" – Compares average payments across different term lengths.
• Trend Line (Optional): Plot total interest paid over time to visualize cost trends based on rate increases or term extensions.
