Every time you invest in a mutual fund, a fee is deducted from your investment by the fund house or asset management company (AMC). This fee is called the total expense ratio (TER) and it encompasses management and administrative costs, marketing expenses and other operational charges. This fee is typically charged as a percentage of your investments in the mutual fund.
While it may seem like a small percentage, this fee can add up over time, affecting your overall wealth creation. Given the charges deducted from the fund's total returns, you may not notice that part of your investment gains is taken by the AMC rather than reinvested for more growth.
