What you actually keep after selling — every rate visible and editable.
STT, exchange transaction charges and the SEBI fee are levied on turnover. GST applies to brokerage plus transaction plus SEBI fee — not to STT or stamp duty. Stamp duty applies on the buy side only. DP charges are a flat amount per scrip on the day you sell, regardless of quantity.
The reason this matters for IPOs: on a small allotment the flat DP charge can be a meaningful share of a modest listing gain, which the headline "gain %" never shows you.
