What should be the minimum hike to consider the switch?

I've 1 YOE, my current in hand is 8.3 LPA with a permanent remote option. What should be a minimum increment below which I should not even consider that option. I'm assuming whatever offers I'll get they are going to onsite and mostly in BLR/NCR . On a CTC of 12 LPA I don't think it will improve my savings considering the cost of living in metro cities and since I live with my parents so current cost is almost zero. In terms of work life balance and culture I'm happy with my current company.
