Managing multiple credit cards effectively can enhance your credit profile, but it requires discipline. Experts emphasize the 30% rule, advising that users should not exceed 30% of their total credit limit across all cards to avoid negative impacts on their CIBIL score. Manish Shara, Co-founder and CEO of ZET, notes that credit scoring models focus on utilization behavior rather than the number of cards held. Anand Agrawal, Co-founder of FixMyScore, suggests using cards for specific purposes, like essentials or travel, to lower overall utilization. However, managing multiple cards can be challenging, as it increases the number of due dates and payment obligations, which can lead to missed payments and financial stress. Experts recommend automating payments to mitigate these risks. Additionally, carrying a balance can lead to high interest charges, with rates ranging from 36% to 42% annually. Maintaining a disciplined approach to credit card use is crucial for building and repairing credit scores.
