Final Balloon Payment: ${bpc_formatCurrency(balloonAmount)}

Total Number of Regular Payments: ${termMonths}

Total Interest Paid: ${bpc_formatCurrency(totalInterestOverall)}

Total Amount Repaid (Incl. Balloon): ${bpc_formatCurrency(totalAmountRepaidOverall)}

(Note: Amortization final balance of ${bpc_formatCurrency(finalCalculatedBalance)} should approximate the balloon payment. Slight discrepancies can occur due to rounding.)
