Formulas Required

The template uses advanced Excel formulas for accuracy and automation:

• PMT Function: Calculates monthly payment amount using the formula =PMT(interest_rate/12, loan_term, -loan_amount).

• CUMIPMT & CUMPRINC Functions: Sum up total interest and principal paid over specific periods.
• DATE Function with EOMONTH: Automatically calculates payment dates for subsequent installments.
• IFERROR Function: Ensures clean display when calculations are incomplete or invalid.

Conditional Formatting

• High Interest Burden: Highlight payments where interest exceeds 40% of total payment.
