You will be allowed to spend 10% over your credit limit.
For this, a service charge equal to 2.5% of the over-limit amount will be charged, with a minimum fee of ₹500. For instance, if you have spent ₹15,000 over your credit limit, the over-limit fee (at 2.5%) is ₹375. Now, since this fee is less than ₹500, you will be charged ₹500 as the minimum over-limit fee.
