Table Structures and Columns (Main Calculator Sheet)

The Main Calculator worksheet features a clean, intuitive table layout with clearly labeled input fields:

Formulas Required

The following Excel formulas are implemented across the template to ensure accurate and real-time calculations:

• Monthly Payment (Main Sheet):
  =-PMT(Annual Interest Rate/12, Loan Term*12, Loan Amount)
  Adjusts for payment frequency using IF or nested functions for bi-weekly and quarterly.
• Amortization Schedule (Dynamic Table):
  Uses OFFSET, INDEX, and CUMPRINC/CUMIPMT functions to generate period-by-period breakdowns.
• Total Interest Paid:
  =Total Payments - Loan Amount
  Where Total Payments = Monthly Payment × Number of Periods.
• Remaining Balance:
  Formula in each row that subtracts principal paid from the previous balance.

Conditional Formatting Features

To enhance readability and highlight critical financial milestones, the template includes robust conditional formatting:

• Overdue Status: If a payment date is past today’s date and payment not marked as "Paid", the row turns red.
• High Interest Rate Warning: If interest rate exceeds 6%, the cell background turns yellow for immediate attention.
• Premium Payment Highlight: Payments above average by 15% are displayed in green to flag exceptional outflows.
• End of Term Coloring: The final payment row is shaded with a distinct color to indicate loan closure.
