₹5 lakh credit card limit but you only use ₹70k? Can unused credit help your CIBIL score

A high credit-card limit does not automatically mean you should spend more. In fact, if you have a ₹5 lakh credit limit but regularly use only ₹70,000, the unused portion can work in your favour by keeping your credit utilisation low.

But can a low credit card utilisation ratio help your CIBIL score? What is a healthy credit utilisation ratio, and should you ask your bank for a higher limit just to improve your score?

₹5 lakh limit, ₹70,000 spending: Does low utilisation matter?

The credit utilisation ratio shows what percentage of your total available credit limit you are currently using.


Credit utilisation ratio = outstanding credit-card balance ÷ total credit limit × 100

Suppose you have a credit-card limit of ₹5 lakh and your outstanding balance is ₹70,000. Your credit utilisation ratio, or CUR, is 14%.

A lower utilisation ratio generally indicates that you are using a smaller portion of the credit available to you.

A 14% utilisation ratio is a strong level, says Dr Raj P Narayanam, Executive Chairman, Zaggle.

He says keeping utilisation below 30% is a useful benchmark, while borrowers targeting a very high score may aim for below 10%.

However, the ratio should not be viewed alone.

Repayment history remains more important than utilisation, he adds. A person who consistently pays credit-card bills on time is in a stronger position than someone who keeps utilisation low but misses payments.

This means unused credit can help indirectly. A larger available limit can keep the utilisation ratio lower, provided spending does not rise along with the limit.

A person using 40% of the limit is not automatically a bad borrower, particularly if all dues are paid on time. But, among borrowers with otherwise similar repayment records, a lower utilisation ratio can indicate that less of the available revolving credit is being used.

Additionally, utilisation needs to be considered both card-wise and across all cards.

For example, having several cards with low overall utilisation does not necessarily erase the signal from one card that is being used very heavily, points out Narayanam.

So, if you have three cards with a combined limit of ₹10 lakh and use ₹1 lakh in total, your overall utilisation is 10%. But if almost the entire ₹1 lakh is sitting on one card with a ₹1.2 lakh limit, that individual card has utilisation of more than 80%.

Credit utilisation is not the same as how much you spend

This is one of the most important things cardholders need to understand.

Your credit utilisation reported to a bureau is linked to the balance reported by the card issuer. It is not simply the total amount you spent during the month.

Narayanam says the statement-generation date is particularly important. For example, if you have a ₹5 lakh limit and spend ₹1.5 lakh, your utilisation would be 30% if that balance is what gets reported.

Even if you pay the entire ₹1.5 lakh by the payment due date, the balance may already have been reported to the credit bureau based on the issuer's reporting cycle.

This does not mean you should rush to make payments before every statement. The practical point is to understand when your card issuer generates the statement and reports the balance, and how that timing affects the balance reflected in your credit report.

If keeping reported utilisation low is important before applying for a major loan, Narayanam suggests making a payment before the statement-generation date so that a lower balance is reported.

Can a high unused credit limit help when applying for a loan?

“A high credit card limit which is not used is beneficial because it shows banks that you are able to handle a big credit line responsibly,” says Kundan Shahi, Founder, Zavo.

However, lenders place greater emphasis on whether borrowers actually repay their credit-card dues and manage their existing liabilities responsibly than simply on the size of the sanctioned credit limit.

“So if you regularly pay off your credit card bill and have a zero balance, this will show the banks that you are a good candidate for bigger loans,” he says

On the other hand, if you have a high limit balance every month, it will show the banks that a big part of your income is being used for credit card payments. This will decrease the loan amounts banks will offer you. So in order to get a bigger loan, you need to be responsible about your credit card and have a low balance, he adds.

For example, someone with a ₹5 lakh limit who regularly pays the full bill and maintains a low outstanding balance presents a different credit picture from someone who repeatedly carries a large balance and pays only the minimum amount due.

What cardholders should remember

An unused credit limit can indirectly support a healthy credit profile because it can keep credit utilisation low. But the benefit comes with an important condition: the larger limit should not encourage larger, unaffordable borrowing.

For a ₹5 lakh card limit, using ₹70,000 means 14% utilisation. That is comfortably below the commonly used 30% benchmark. But a cardholder should not chase a lower ratio at the cost of missing a payment or carrying expensive debt.

The bigger picture is simple: use the credit you need, keep reported utilisation under control, repay on time and treat a higher limit as available borrowing capacity—not extra income.
