DP charges do not appear on your contract note because the contract note captures all trading-related charges executed on stock exchanges. DP charges apply when you sell shares in your demat account. Since DP charges and contract note charges are separate, Zerodha levies DP charges separately on the funds statement and not on the contract note.
Did you know? Account maintenance Charges (AMC) are also levied separately on the funds statement and not on the contract note.
