The extra money saved in the credit card is called overpayment, which is accumulated on the credit limit, and will be taken up first the next time you make a purchase.
After recharging a credit card, there may be an "over-deposit" on the credit card. The amount is equal to the total deposit amount minus the amount owed in the bill that has been issued. Most card-issuing banks will treat cardholders' withdrawals from their own deposits as overdrafts and charge a certain fee.
Calculation method:
For example: Mr. A deposits 5,000 yuan into his credit card and his outstanding bill balance is 2,600 yuan, then the system will automatically repay the credit card debt first and the remaining balance. The portion of 2,400 yuan remained in Mr. A’s account as an “overflow deposit”. It can be seen that even if you deposit money into a credit card before the final repayment date, there will not be as much "excess deposit" as you deposit.
In the above example, if Mr. A wants to withdraw his 5,000 yuan deposit, the 2,600 yuan that has been used to repay the debt will be treated as an overdraft withdrawal, and he will also need to pay 50,000 yuan of interest per day.

Notes:
1. Credit cards are not debit cards. Depositing money on a credit card will not result in a higher credit limit except for the higher limit when swiping the card. How many benefits.
2. Even if you deposit money into a credit card before the final repayment date, it does not mean that there will be as much "excess deposit" as you deposit.
3. "Excess deposits" will not generate any interest. In other words, there is no benefit to "recharging" your credit card in advance and then spending.
4. Do not withdraw the "overflow deposit" easily. Generally, you only need to clear the account before canceling the card. In other cases, you can use the "overflow deposit" by directly swiping the card for consumption.
5. If the cardholder wants to increase a certain credit limit, he or she can apply for a temporary limit from the bank customer service center. There is no need to rely on "excess deposits" to increase spending power.
