The remaining 600 available quota means you still have 600 available. What do you mean this month and last month? The credit does not belong to any month. If you still have a limit of 600, you can still overdraft 600. Before other overdrafts have been repaid and before you start a new overdraft consumption, your available limit is only 600, which is not what is left over from last month. The rest. The limit is the overdraft indicator given to you by the bank, not cash. It's not even your money. If you owed 1,400 last month and then repaid 2,000, the extra 600 will be called the remaining 600 from last month. If you swipe your card again, you will use the extra 600 first (that is, it will be filled in automatically). Use the quota again. The available credit is the credit that has not been used, and of course it is always on the card.

You only have one cup, which can only hold one cup of water. There is still half a glass of water left in your glass. Can you use it to get another glass of water?

You only have a quota of 1,000. If you use 600, you will have 400 left. Before you repay the 600, you can only use 400 again. If you repay 100, you can use 500 more. If If you repay 300, you can use another 700. If you repay 600, you can immediately overdraft another 1,000. You don't have a 1,000 limit every month. The 1,000 quota is the maximum quota, and the remaining unused quota is called the available quota. The quota is not traffic and will not be accumulated and carried forward. If you treat a guest to a meal, and it is said that the standard is to serve food at no more than 300 per person, but the average consumption per person is 150, then should you give each person a red envelope of 150? Didn’t each of them not eat enough 300 and still have 150 left? Isn’t it a beautiful thought? You think beautifully yourself.
