ETF vs Index Funds: The Hidden Costs Behind ‘Low-Cost’ Investing

ETF vs Index Funds: The Hidden Costs Behind ‘Low-Cost’ Investing Exchange Traded Funds (ETFs) are often promoted as the cheapest way to invest in the stock market due to their low expense ratios. However, a closer look shows that the actual cost of investing in ETFs can be higher than it appears, especially for long-term and small investors.

A growing body of investor experience suggests that plain index mutual funds may, in many cases, be more cost-effective and convenient than ETFs, despite having a slightly higher expense ratio on paper.

Here’s a simple explanation of where the hidden costs lie and who should choose what.

The Invisible Costs of ETFs ETFs are traded on stock exchanges, similar to shares. While their expense ratio may be low, investors often face additional indirect costs that are not immediately visible.

1️⃣ Entry Cost Through Market Price Unlike index funds, ETFs are not bought directly from the fund house at NAV. Investors purchase them from the market.

An ETF with an NAV of ₹100 may trade at ₹104–₹105

This difference acts like a hidden entry load

Over time, this cost can significantly reduce returns, especially for SIP investors.
