Own multiple credit cards? Remember this 30% rule to maintain your CIBIL score

Key Insights

1. The 30% Credit Utilisation Rule is the Single Most Powerful Tool to Protect Your CIBIL Score. Credit utilisation contributes between 20% to 30% of your overall credit score.

2. Starting in January 2026, the RBI has mandated a reporting cycle for all institutions under this rule. Your score can improve or drop depending on your repayment behaviour.

Why the 30% Rule Is Non-Negotiable for Every Indian Credit Card Holder

If you own two, three, or even five credit cards, it's easy to feel financially empowered but mismanaging them can quietly destroy your CIBIL score.

In India, 35% of a CIBIL score is based on repayment history, while 30% relates to credit exposure, meaning your repayment behaviour.

Credit utilisation ratio plays a greater role in shaping your score than the number of cards you hold.

The risk is very real. High utilisation across multiple limits, late payments, and frequent card applications significantly reduce your score.

In the short term, a falling CIBIL score can block loan approvals; in the long term, it can cost you lakhs in higher interest rates or rejections when you need credit the most.

What This Means for Millions of Indians Using Credit Cards

As of January 2026, India had 11.66 crore credit cards in circulation, and a large chunk of holders are unaware that they may be hurting their own scores.

The good news is that multiple cards, when used right, can actually work in your favour.

Multiple credit cards can increase your overall available credit and help lower your credit utilisation ratio, as long as your total spending stays controlled.

If one individual holds an SBI credit card with a ₹1 lakh limit and an IndusInd Bank card with a ₹50,000 limit, spending ₹40,000 only from the IndusInd card pushes utilisation to a damaging 80%.

Splitting the same spend ₹30,000 from SBI and ₹10,000 from IndusInd keeps both cards under the safe 30% threshold.

What Experts Say And What You Should Do Right Now

Financial experts are clear: discipline, not the number of cards, is what matters.

Experts recommend assigning one card per spending category: groceries on Card A, travel on Card B, so rewards don't get diluted and tracking stays clean.

They also suggest setting up auto-pay for at least the minimum due on every card to prevent missed payments.

With the RBI's new fortnightly reporting rules now live, the margin for error has shrunk further.

Automating payments prevents accidental delays, keeping utilisation below 30% demonstrates responsible credit use, and regularly reviewing your free credit reports allows you to catch errors early.

Conclusion

The 30% rule is straight but effective. No matter how many cards you have, keeping your credit utilisation under 30%, paying your bills on time, and applying your spending across cards can protect and even improve your CIBIL score.
