Zerodha’s zero-brokerage approach has saved its investors over Rs 27,000 crore year-to-date since 2016, Founder Nithin Kamath said. The Bengaluru-based discount broker is one of the very few players that charge zero brokerage on delivery trades, while it charges Rs 20 per day on intra-day and futures & options (F&O). The company would have charged Rs 50 currently if it had adjusted for inflation, as per a bulletin on the company’s website on Thursday. Its brokerage has stayed flat even as the rest of the industry revised theirs, it added.
