Required Formulas

• PMT Function: =PMT(annual_rate/12, term_in_months, -loan_amount) → Used in Loan Summary and Amortization Schedule to calculate fixed monthly payment.
• IPMT Function: =IPMT(rate, period, nper, pv) → Calculates interest paid in a specific month.
• PPMT Function: =PPMT(rate, period, nper, pv) → Calculates principal portion of the payment.
• Date Incrementation: =DATE(YEAR(A2), MONTH(A2)+1, DAY(A2)) → Auto-updates payment date for next month.
• Habit Score Calculation: =COUNTIF(HabitComplianceColumn, "Yes")/COUNTA(HabitComplianceColumn)*10 → Converts compliance ratio into a habit score out of 10.

Conditional Formatting Rules

• Past Due Payments: Highlight any payment date that is earlier than today with a red fill and bold text (use conditional formatting: "Date is before" = TODAY()).
• Habit Compliance: Green background for "Yes", red for "No" in the Habit Compliance column.
• Remaining Balance: Light blue gradient where balance is above 75% of original, yellow at 50%, and red when below 25% (visual cue on loan progress).
• Late Payments: Highlight entire row in orange if payment was not made by the due date.
