Dear Friend,
You may be aware that if you want to get a fair idea about the salary paid for a particular job post, some job portals like Naukri and Shine have tools that can provide information on what a person can earn in a specific industry, location, and based on skills, etc. I recommend trying them out to see if it helps you.
As one of our friends mentioned earlier, a proper hike to be demanded in the industry is around 30%. This is unless you are changing your position, location, or other circumstances, etc.
I hope this information is helpful to you.
Best regards
