The Postal Savings Credit Card repays 7 15 yuan (i.e. 24 installments) every month within two years (according to 24 installments, the handling fee for each installment is 0.6%, and there is no handling fee for early repayment).
Calculation method of fifteen thousand in the twenty-fourth period:
Handling fee: 15000X0.6% = 90 yuan.
Principal: 15000÷24=625 yuan.
Then pay it back every month (principal+handling fee =625+90=7 15 yuan).
