The conclusion is that users who have already applied for credit card installment payments can indeed pay it off in one go. But be aware that doing so may involve additional fees and conditions. First, you need to apply through customer service and pay immediately after the money is credited to your account. However, it should be noted that the bank may charge interest on a daily basis for each day of repayment in advance. Installment fees are generally not waived for early repayment and need to be paid in full, regardless of the number of installments remaining.

Secondly, early repayment may incur liquidated damages, especially the installment fees and service fees incurred, which are usually not refundable. Once you choose to settle in one lump sum, your credit limit will be restored immediately, but the corresponding default costs need to be taken into account.

Legally, the Contract Law allows liquidated damages to be stipulated, so if you choose to repay the loan early, you may need to pay a certain amount of liquidated damages as stipulated in the contract. In addition, credit card repayments usually have a grace period, and late payments will accrue interest and late fees will also be charged.

In general, while a lump sum repayment is possible, there are associated fees and implications to consider, so it’s best to check with your bank to understand the specific terms and fees before making a decision. Repayment policies may vary depending on the bank and type of credit card.
