The two main costs incurred are:
1) Expense Ratio: Annual expenses involved in running the mutual fund include administrative costs, management salary, overheads etc. Expense Ratio is the percentage of assets that go towards these expenses. Every time the fund manager churns his portfolio, he pays a brokerage fee, which is ultimately borne by investors in the form of an Expense Ratio. Therefore, higher churning not only leads to higher risk but also higher cost for the investor.
2) Exit Load: Due to SEBI's recent ban on entry loads, investors now have only exit loads to worry about. An exit load is charged to investors when they sell units of a mutual fund within a particular tenure; most funds charge if the units are sold before a year. As exit load is a fraction of the NAV, it eats into your investment.
Try investing in a fund with a low expense ratio and stay invested in them for longer duration.
