You’ve worked hard to get above 750. But that old card sitting in your drawer with a zero balance? It’s doing more for your score than you think. Closing it could cost you 15 to 40 points.
Credit Age Is 15% of Your CIBIL Score
CIBIL calculates your score using payment history, utilisation, credit age, credit mix, and enquiries. Credit age alone carries 15% weight. Two specific metrics drive this factor:
- The age of your oldest account
- The average age across all your accounts
A credit history of seven years or more is considered a strong benchmark. Every account you keep open contributes to that average. Every account you close pulls it down. If your oldest card is also your zero balance card, closing it directly shortens your longest credit relationship.
What Happens When You Close an Old Card
Closing a card does two things at once, and both hurt. First, it removes years of history from your active credit file. A closed card stays on your CIBIL report for about 7 to 10 years, but after that, its positive contribution disappears completely.
Second, closing a card reduces your total available credit limit. If you have two cards with a ₹2L total limit and close one, your available limit drops to ₹1L. Your utilisation ratio doubles overnight, even if your spending hasn’t changed. That hits the 30% factor of your score.
Someone with a 780 score who closes a 5-year-old card could see their average credit age drop from 6 years to 2 years. That alone can trigger a 25 to 35 point decline.
Keep the Card. Use It Once Every Few Months.
If your old card has no annual fee, keeping it open requires zero effort. But even fee-free cards can get auto-closed by the issuer if they sit completely inactive for 12 months or longer. That auto-closure shows up on your credit report and can lower your score.
The fix is simple. Use the card for one small purchase every 3 to 6 months:
- A ₹99 OTT subscription
- A ₹200 mobile recharge
- Any small recurring bill on autopay
One transaction every quarter keeps the account active, the history intact, and your score protected.
Downgrade Instead of Closing
If the card has an annual fee you don’t want to pay, don’t close it. Call your issuer and ask to downgrade to a basic, zero-fee variant. Most banks allow this. You keep the same account number, the same opening date, and the same credit age contribution. The only thing that changes is the card tier.
This works especially well for cards you opened 5 to 10 years ago. That history is valuable. Paying ₹500 to ₹2,000 in annual fees to preserve it might not make sense, but throwing away the history makes even less sense. Downgrading gives you the best of both outcomes.
If downgrading isn’t available, try calling before your renewal date and asking for a fee waiver. Banks frequently waive fees for customers with scores above 750. One phone call can save both the fee and your credit age.
The “Fewer Cards Is Better” Myth
Many people above 750 feel the urge to simplify. Fewer cards, cleaner wallet, less to track. It sounds logical. But CIBIL doesn’t reward simplicity. It rewards longevity and responsible management.
Your zero balance card is proof that you can hold credit without misusing it. Lenders see an account that’s been open for years with zero outstanding. That’s a positive signal, not a dormant liability.
Closing cards does not improve your score. It does not remove negative history either. If the card had late payments in the past, closing it won’t erase those records. They stay on your report regardless.
The only scenario where closing makes clear sense is if a card charges high fees, cannot be downgraded, and the issuer won’t waive the charge. In every other case, keep it open.
Your Checklist for Protecting Credit Age
Here’s what to do this week:
- Pull up your CIBIL report and note the opening date of each account
- Identify your oldest card. If it’s inactive, set up one small autopay on it
- If any card has an annual fee, call the issuer to explore a downgrade or fee waiver
- Read our 2-Minute Tip on how switching card networks preserves your credit age
- Avoid closing any account without checking how it affects your average credit age first
Your score above 750 reflects years of disciplined credit behaviour. Protect that history by keeping your accounts open, active, and working for you.
