Yes, your gross salary will include all the amount you receive from your company in your salary account.
That will include all the bonus / performance based pays that you will receive whenever you receive it.
For eg. In your CTC the performance amount is 50,000 but you only get 20,000 out of it, then your gross sal will include 20k and not 50k
It would help if you could tell us for what purpose you need to know the gross salary.
For eg, if you are talking about other companies who ask your salary, then you have to mention your CTC and not gross salary unless they specifically ask for the same.
