Formulas Required

The template leverages advanced Excel formulas to ensure real-time accuracy and automation:

• =PMT(rate, nper, pv): Calculates monthly payment in Loan Calculator (e.g., =PMT(B3/12, B4*12, -B2))
• =SUMIFS() and =COUNTIFS(): Used across KPI Tracker to aggregate data by date period or status.
• =IFERROR(): Wraps all complex formulas to prevent errors when inputs are missing.
• =VLOOKUP / =XLOOKUP: For cross-referencing borrower data in portfolio table.
• =DATE() and =EDATE(): For automated date calculations, especially for loan maturity dates.
• Dynamic KPI Formulas:
  • Default Rate (%) = COUNTIF(Status Column, "Defaulted") / COUNTA(Status Column)
  • Average Loan Size = AVERAGE(Principal Amount Column)

Conditional Formatting

To enhance visual analytics and alert users to critical changes:

• Loan Status: Red font for "Defaulted", yellow for "Delinquent", green for "Repaid".
• KPI Thresholds: If Default Rate exceeds 5%, highlight the cell in red; if below 2%, use green.
• Current Balance: Conditional formatting to show decreasing balance over time (gradient fill from light blue to dark blue).
• Amortization Schedule: Highlight payments where interest > principal using color scale.
