If we are to pay 1% turnover charges in ETF transaction than how far it is beneficial for us ?
What turnover charge are you talking about?
Talking about bank of Barodacap : Turnover charges .45% on both buying and selling of etfs or scripts. I know that zerodha don’t have delivery charges. I vave nsdl account with bank of baroda. I have account with zerodha to.
The buy through Zerodha, problem solved 
Close your Baroda a/c while you are at it too.And to answer your questions, the more charges you pay, the lesser your returns. Costs matter, important to keep them low.
