What should be a salary of 2.5 years experienced flutter developer in mumbai?

I have worked for 2 years in a startup which was WFH. Now i am working from office in my new company with CTC 12 LPA. I feel like i am under paid because i hardly saves 20% of my salary per month. Should i switch my job or stay in this company for a while. I have worked as solo developer on big projects.
