How much increment can I expect

I joined Deloitte Touche Tohmatsu in Aug 2023. My current CTC is 15.5LPA. My seniors are in support of my promotion. I have received an award from the client for the work I delivered and my rating is pretty good as well 9.69 on 10. 1. What can be the percentage of appraisal 2. Is it true that if you get promoted the salary increment is usually lesser?
