The margin currently blocked by Kotak Securities is different from the margin shown in the margin calculator, as the required margins change throughout the day as per the margin files published by the exchange.

SPAN and exposure margins on the margin calculator are updated once, at the beginning of the trading day. However, the actual margins required and blocked by Kotak Securities are dependent on the margin files released by the exchange.
