The Bank of Communications credit card has 12 installments, and the installment fee rate for each installment is 0.72%.

The installment handling fee for each installment = the total installment amount * the installment handling fee rate for each installment = 8000 * 0.72% = 165.6 yuan;

The principal payable for each installment = the total installment amount /Number of installments=230000/12=1916.67 yuan;

Total monthly repayment amount=installment fee per installment+principal repayment per installment=165.6+1916.67=2082.27 yuan.
