Expense ratio
The expense ratio is the yearly fee a mutual fund or ETF charges for running the fund, shown as a percentage of the money in it. You never get a separate bill. The fee is taken out of the fund's value, so it quietly lowers your return every year.
How it is charged
The fund house works out the cost for each day and takes it out of the fund before it calculates the NAV. A fund with an expense ratio of 1 percent charges about ₹1 a year for every ₹100 of your money in it. Because it is taken inside the NAV, you see it only as a slightly lower NAV and a lower return.
What it pays for
It covers the fund manager and research team, administration, record keeping and the costs of buying and selling. In a regular plan it also includes a commission paid to the distributor who sold you the fund. A direct plan has no such commission, so its expense ratio is usually lower.
Why it matters over time
A small yearly fee compounds against you, because it reduces the base that grows every following year. Index funds and ETFs, which only copy an index, usually have lower expense ratios than funds where a manager picks shares. SEBI sets limits on what funds may charge, and the limits can change, so check the fund's current figure in its documents.
A low fee is not the whole picture
The expense ratio is one cost of owning a fund, not a measure of how good it is. A fund with a low fee can still fall, and a fund with a higher fee can sometimes justify it. The fee is a known cost, while the return is not.
How a fee compounds (hypothetical numbers)
Suppose ₹1,00,000 grows at 10 percent a year before costs for 20 years. With an expense ratio of 0.2 percent, it grows at about 9.8 percent a year after costs and reaches about ₹6,48,704. With an expense ratio of 1.5 percent, it grows at about 8.5 percent after costs and reaches about ₹5,11,205. The difference is about ₹1,37,499, from the fee alone.
Common questions
- What is an expense ratio in simple words?
- The yearly fee a fund charges, as a percentage of the money in it.
- Do I pay the expense ratio separately?
- No. It is taken out of the fund's value, so it shows up as a lower NAV and a lower return.
- What is the difference between a direct and a regular plan?
- A regular plan includes a distributor's commission in its expense ratio. A direct plan does not, so its expense ratio is usually lower.
- Is a lower expense ratio always better?
- It means a lower cost, which helps, but it does not say how well the fund will perform.
