• =FV(rate, nper, pmt): Used to verify remaining balance after each month’s payment.
• =SUMIFS(): To calculate total interest paid over time via sum of interest components.
• =IF(remaining_balance <= 0, "Fully Paid", "Active"): Determines loan status dynamically.
• =DATEDIF() or date arithmetic to auto-generate due dates and calculate term durations.

Conditional Formatting

The template uses conditional formatting to highlight critical data:

• Red Highlight on Interest > 10%: Flags loans with high interest rates for team review.
• Green Background if Monthly Payment is under $500: Indicates low-cost, accessible financing options.
• Yellow Alert when Loan Term exceeds 30 years: Warns about long-term liabilities.
