Formulas Required

The following formulas power the dynamic calculations in this template:

• Monthly Payment (PMT): =PMT(annual_rate/12, term_in_months, -principal) – Calculates monthly payment based on interest rate and loan term.
• Total Interest Paid: =SUM(Total Payments) - Principal – Derived from amortization logic.
• Effective Annual Rate (EAR): =((1 + monthly_rate)^12) - 1 → Converted to percentage format for visibility.
• Productivity Impact Score: =IF(Interest/Payments < 0.2, 9, IF(Interest/Payments < 0.3, 7, IF(Interest/Payments < 0.4, 5, 3))) – A rule-based score based on interest efficiency.
• Automatic Loan ID Generation: =IF(ISBLANK(A2), "", "L-" & TEXT(DATE(YEAR(TODAY()), MONTH(TODAY()), 1), "00") & "-" & TEXT(ROW(), "00")) – Generates unique IDs per entry.
• Dynamic Status Update: =IF(C4="Paid", "Closed", IF(C4="Active", "Open", "In Review")) – Updates status based on input.

Conditional Formatting Rules

• High Interest Warning (Red): If “Total Interest Paid” exceeds 30% of Loan Amount, applies red background to the cell.
• Productivity Score Highlighting (Green/Yellow/Orange): Scores above 8 → Green; 5–7 → Yellow; below 5 → Orange.
• Payment Due Reminder: If “Last Updated Date” is over 30 days old, cell turns light gray with bold text indicating outdated data.
• Loan Term Flagging: Loans longer than 15 years appear in light purple background to draw attention to long-term obligations.
