Can tcs change qvp % after promotion to c3a ? Currently 9% c2.

Yes, the increment percentage will be more in terms of variable after C2 to C3A. It’s a trick which tcs uses to reduce the inhand salary of C3A and above associates. As of now you must be aware, associates are barely getting 10-20% QVA for C3A and above.

it supposed to be 100% for c2 right ?

Looking at this structure it’s better to take a promotion and switch. Let’s see how the things move.

Thanks for your inputs, much appreciated.

Yes . For C3 and above till C5 it's 15% of CTC
