What will be my in hand monthly in HCL tech for 34 lpa fixed and 37 lpa overall. I will select new tax regime.

You should already be able to do this. Or atleast put an effort to learn, now what you'll be earning. Anyways, with new tax regime, it should be around 5.5 L on fixed

Hey, did you get the answer for this ?

Expect 2.6 monthly based on the fixed part for new regime
