Credit Line on Credit Card India: How Overdraft Works
Credit Line on Credit Card in India: How It Works and When to Use It
A credit line on a credit card refers to the revolving credit facility your bank extends when it issues you a credit card. More specifically in India, it also refers to overdraft or personal loan products that are extended on top of your existing credit card relationship, sometimes called a loan against credit card or credit card cash advance line.
This is one of the most accessible forms of credit for existing cardholders because approval is almost instant and no fresh documentation is usually required.
Overview of Credit Lines on Credit Cards
Every credit card has a credit limit, which is the maximum amount you can spend in a billing cycle. When you carry a balance beyond the interest-free period (usually 45 to 55 days), interest kicks in. This revolving structure is the basic credit line on a credit card.
Beyond this, many banks offer a second product called Loan on Card or Insta Loan, where they convert your available credit limit (or offer an additional line) into a structured EMI loan. Banks like HDFC Bank’s Insta Loan, ICICI Bank’s Insta Finance, and SBI Card’s Encash offer this.
Interest Rates
Credit card interest rates in India are among the highest for any formal retail credit product. Here is what you need to know:
| Charge Type | Typical Rate |
|---|---|
| Revolving credit (APR) | 36% to 48% per annum |
| Loan on Card (EMI) | 12% to 24% per annum |
| Cash advance interest | 36% to 42% per annum + 2.5% cash advance fee |
| Late payment fee | Rs 100 to Rs 1,300 per cycle (varies by outstanding) |
The RBI capped credit card cash advance fees and directed full disclosure of APR on all credit card agreements. However, revolving interest rates are not directly capped, though the RBI has pushed for Fair Practices Code compliance from card issuers.
Eligibility for a Credit Line or Loan on Card
- Must be an existing credit cardholder of the issuing bank
- Good repayment history with the card (usually at least 6 to 12 months)
- Available credit limit must be sufficient for the cash portion (for loan-on-card products)
- No significant delinquency or defaults in recent months
Documents Required
For a loan on card or cash advance from an existing credit card, no fresh documents are generally required. The bank uses your existing KYC and credit history. Some lenders may ask for a fresh income proof if the top-up amount is large.
How to Use a Credit Line on Your Credit Card
- Log in to your bank’s mobile app or credit card portal
- Go to Card Services or Loans section
- Check if you have a pre-approved Loan on Card or Insta Loan offer
- Select the amount (subject to your available limit) and tenure
- The loan is disbursed to your linked savings account or directly charged to your card
- Repay in fixed monthly EMIs through autopay
Frequently Asked Questions
Is a credit card revolving line cheaper than a personal loan?
No. Revolving credit card interest at 36% to 48% per annum is far more expensive than a personal loan at 10.75% to 18%. If you cannot repay the full bill, converting the balance to a Loan on Card (12% to 24%) is much cheaper than letting it revolve.
Does using a credit card cash advance affect my credit score?
Frequent cash advances are seen as a sign of financial stress by credit bureaus and can lower your score. They also have no interest-free period; interest starts from the day of withdrawal.
What is the difference between a Loan on Card and a personal loan?
A Loan on Card uses your existing credit card relationship and requires no fresh application. It is disbursed quickly but reduces your available credit limit during the loan period. A personal loan is a separate account with its own credit limit and does not affect your card’s availability.
Can I get a credit card with a higher credit line if my income has increased?
Yes. Most banks allow you to request a credit limit enhancement online after 6 to 12 months, supported by your latest salary slip or ITR. A higher income with clean repayment history usually gets the upgrade approved within 2 to 3 working days.
