Income tax on share sale: adjust brokerage etc towards cost and sale value?

I have sold some shares in FY 21-22. I find that the cost and sale proceeds have these components:

Total cost to me: traded value+brokerage+charges by exchange+charges by sebi+STT

Total sale proceeds received by me: traded value- brokerage-charges by exchange-charges by sebi-STT

What should I use as cost of shares and sales proceeds to calculate gains for calculation of tax?

Example:

Cost= 50 shares @ Rs 300 : 15000+250+35+1+150  =15436

Sales proceeds= 50 shares @ Rs 500: 25000-350-45-2-260  =24343
