The amount of the credit card bill is determined based on the consumption amount and repayment status of your card. If you repay the same amount a few days after swiping your card, the amount due on the next bill will generally not increase. This is because credit card bills are generated based on consumption and repayments within each billing cycle. If you paid off your previous purchases during the billing cycle, the amount due on your next bill should not change.

However, it should be noted that different banks and credit card institutions may have different billing cycles and repayment date regulations. If your repayment happens to be at the end of the previous cycle, it may result in an increase in the amount of your bill next cycle. In addition, if your billing cycle and repayment cycle are different, it may have an impact on the bill amount.

In short, paying back the same amount of money a few days later will usually not cause the next bill to increase. However, specific circumstances may vary depending on individual consumption behavior and credit card institution regulations. It is recommended that you read the relevant terms of your credit card carefully or consult your credit card issuer for accurate information.
