Credit card loan repayment involves paying back the borrowed amount on a credit card, which includes the principal balance, interest, and any applicable fees. Timely repayment is crucial to avoid high interest charges and penalties. Borrowers can choose to pay the minimum due, full outstanding balance, or set up an EMI (Equated Monthly Installment) plan for large expenses. Maintaining regular payments improves credit scores and reduces debt burden. Automated payments and budgeting help manage timely repayments and prevent financial strain.
