No fee is charged to users for investing in mutual funds. However, it is important to understand that Motilal Oswal only offers 'regular mutual fund schemes' and not 'direct mutual fund schemes'. Regular mutual fund schemes charge a higher expense ratio - (expense ratio is a fee charged by all mutual funds schemes from mutual fund investors). Regular mutual fund schemes charge a higher expense ratio because they have built-in commissions for mutual fund distributors/platforms selling regular mutual fund schemes like Motilal Oswal.
