Sheet Names and Structure

• Amortization Schedule: Detailed month-by-month repayment breakdown.
• Data & Instructions: Guidance sheet with usage instructions, example data, and definitions.

Table Structure: Loan Calculator Sheet

The primary input area on the Loan Calculator sheet includes a structured table for user inputs and calculated outputs.

Table Structure: Amortization Schedule Sheet

This sheet generates a detailed monthly breakdown of payments, showing how much goes toward principal and interest each period.

Formulas Required

The template leverages essential Excel formulas to automate calculations:

• Monthly Payment (PMT function):
  =-PMT(Annual Interest Rate / 12, Loan Term, Loan Amount)
  This formula calculates the fixed monthly payment based on standard loan principles.
• Interest Portion per Period:
  =Remaining Balance * (Annual Interest Rate / 12)
  Computes interest accrued on the current outstanding balance.
• Principal Portion per Period:
  =Payment Amount - Interest Portion
  Determines how much of each payment reduces the principal.
• Remaining Balance:
  =Previous Remaining Balance - Principal Portion
  Updates the outstanding loan balance after each payment.
• Total Interest Paid:
  =SUM(Interest Portion Column)
  Sums all interest payments across the term.
• Payment Date (Dynamic):
  Uses a date formula such as:
  =DATE(Year, Month, Day) + 1*Monthly Period, adjusted based on frequency.

Conditional Formatting

To enhance usability and visual clarity for administrative staff:

• Interest vs. Principal Color Coding: Rows where interest portion exceeds principal are highlighted in yellow to flag high-interest early payments.
• Final Payment Row Highlighting: The last payment row is shaded in light green to indicate loan completion.
• Due Date Reminders: If the payment date is within 7 days of today, the row turns red to prompt action.
