Investing Rs 10K a month for 20 years: Does a 0.5% higher expense ratio in active funds really matter?

The total expense ratio or TER is not just a minor fee but a massive drag on your long-term wealth. When you invest in a mutual fund the fee is not billed to you separately but is subtracted directly from the NAV every single day. Over a 20-year period this daily deduction compounds heavily against you.

If you invest Rs 10K every month in an index fund and someone else invests the exact same amount in an active fund for 20 years straight a mere 0.5% difference in the expense ratio results in a massive Rs 3.9 Lakhs difference in the final corpus. Cost advantage is the primary reason to choose index funds over actively managed ones.

The sole job of an index fund is to replicate its underlying index like the Nifty 50. However this replication process is never perfect and the gap between the index's actual return and the fund's return is called the tracking difference.

This difference occurs due to cash drag where funds keep cash on hand for daily redemptions and rebalancing costs when the underlying index changes. There are also dividend reinvestment delays because fund operations take time to receive the money and reinvest it. Over a 10 or 20-year period this tracking difference compounds just like the expense ratio.

You should always check the scheme document on platforms like Zerodha Coin and choose a fund with the lowest possible tracking difference.
