Table Structures and Columns

Loan Details Sheet – Primary Table Structure:

Formulas Required

• Monthly Payment:
  =PMT(Annual Interest Rate/12, Loan Term (Months), -Loan Amount ($))
  This calculates the fixed monthly payment based on principal, interest rate, and term.
• Remaining Balance:
  =IF(Monthly Payment <> 0, Loan Amount * (1 + Monthly Interest Rate)^Current Month - PMT(Interest Rate/12, Term, -Loan Amount) * (((1 + Monthly Interest Rate)^Current Month) - 1) / Monthly Interest Rate, Loan Amount)
  Or use a simple iterative formula based on prior balance minus principal portion.
• Interest Portion of Payment:
  =Remaining Balance * (Annual Interest Rate / 12)
• Principal Portion:
  =Monthly Payment - Interest Portion
• Total Interest Paid:
  =SUM(Interest Column) (Cumulative across all months in amortization schedule)

Conditional Formatting Rules

• Overdue Payments: Highlight red if payment date is past and status ≠ "Paid"
• Balances Above Threshold: Yellow highlight if remaining balance exceeds 50% of original loan amount
• Maturity Warning: Orange highlight for loans with fewer than 3 months remaining
• Department Spending Summary: Color scale based on department's total loan cost (highest = red, lowest = green)
