First of all, from the perspective of financial management, my opinion is that young people should use credit cards as little as possible. If they want to use them, they will pay for them conveniently. If they want to spend in advance, they will have to bear the pain of repayment. In the end, they often lose many opportunities that could have been used for saving and investing. Points and installment payment are both means used by businesses to stimulate consumption. Don't blindly pursue them. If you have planned consumption to do, credit card payment can bring discounts, so you might as well use it to pay. Remember to use it in the plan.
Secondly, from the point of view of card management, I personally suggest that the credit card of 1-2 is enough, and all the unused ones are cancelled, which is convenient for management. There is no need to apply for many cards for a small gift or for a beautiful wallet, because too many cards will easily lead to missed repayment or bring some various expenses. If you insist on holding so many cards, I have nothing to say. I suggest calling the bank and changing the repayment date of all credit cards to a similar date (most banks can change the billing date and repayment date). For example, if your monthly salary is 1, then the billing date will be set near the 5th, so as to ensure that you can repay in time every time. My idea is never to give credit cards the opportunity to charge interest. The calculation method of interest on credit cards is really outrageous.
Third, from the perspective of efficiency, the interest-free repayment period and interest calculation method of credit cards should be good at calculation. Consumers enjoy the longest interest-free repayment period on the second day of the billing date, generally 45-50 days. Therefore, we should make full use of the interest-free repayment period. In terms of interest calculation, if you don't pay off all the bill amount before the repayment date, the bank will still calculate the interest according to your total amount, even if there is a penny missing. How to understand it? For example, if your bill this month is 500 1 yuan, and you ignore the quick money behind 1 and pay back 5000, then your interest will be calculated according to 500 1 in next month's bill. This caused a lot of users' dissatisfaction, and some banks began to improve and calculate interest according to the unpaid amount.
Finally, if you don't pay the minimum repayment amount on the credit card repayment date every month, the bank will not only impose a penalty interest on you, but also report your bad behavior to the People's Bank of China, and all banks can call up your records. Generally speaking, the bank thinks you have a bad personality, so if you really can't repay, you have to pay a minimum repayment amount, and paying some interest will not be blacklisted, so you can break the money and eliminate disasters.
Having said that, I hope I can help you:-)
