Sheet Names

• Loan Summary: Central dashboard providing a high-level overview of loan terms, total interest paid, monthly/annual payment amount, and remaining balance.

Table Structures and Columns

1. Loan Parameters (Sheet: "Loan Parameters")

2. Annual Payment Schedule (Sheet: "Annual Payment Schedule")

Formulas Required

• Annual Payment Amount: =-PMT(InterestRate/1, LoanTerm, PrincipalAmount)
  This formula calculates the fixed annual payment based on principal, interest rate (annual), and number of periods (years).
• Interest Portion: =BeginningBalance * InterestRate
  Calculates the interest component for each year.
• Principal Portion: =AnnualPayment - InterestPortion
  Determines how much of the payment reduces the principal.
• Ending Balance: =BeginningBalance - PrincipalPortion
  Finds remaining loan balance after the year’s payment.
• Running Balance: The first row begins with PrincipalAmount; each subsequent row uses the prior ending balance as its beginning balance.

Conditional Formatting

• Red Highlight for High Interest: If annual interest exceeds 15% of the payment, cells in "Interest Portion" are highlighted in light red.
• Green Emphasis on Principal Reduction: Years with principal reduction exceeding 60% of the annual payment are shaded green to indicate strong debt repayment progress.
• Warning for Negative Balances: If ending balance is negative (overpayment), it turns bright red to alert the user.
• Dual-Color Scale (Heat Map): The "Ending Balance" column uses a gradient from blue (high balance) to green (low/zero) for visual tracking of loan payoff progress.
