Sheet Names

The template includes three main worksheets:

Table Structures and Data Layout

1. Loan Calculator Sheet

This sheet contains a central input table followed by calculation outputs.

2. Process Documentation Log Sheet

Required Formulas

The following formulas are implemented across the Loan Calculator sheet:

• Monthly Payment (PMT): =PMT(AnnualInterestRate/12, LoanTerm*12, -LoanAmount)
• Total Interest Paid: =TotalRepaymentAmount - LoanAmount
• Total Repayment Amount: =MonthlyPayment * (LoanTerm * 12)
• Amortization Schedule (in hidden section): Uses iterative formulas to calculate principal and interest per month, with cumulative totals.

Conditional Formatting Rules

To enhance usability and visual clarity:

• Overdue Tasks in Process Documentation: If “Date Completed” is blank but “Date Started” was more than 7 days ago, the entire row turns red.
• High Interest Rate Warning: If Annual Interest Rate exceeds 8%, the cell background turns yellow with a warning icon.
• Monthly Payment Threshold: If Monthly Payment exceeds 20% of estimated monthly income (set in a separate input box), the value is highlighted in orange.
