What Are Passive Funds, Anyway?
Before diving into the cost benefits, it's essential to understand what makes a fund 'passive'. Unlike active mutual funds where a fund manager actively picks stocks hoping to beat the market, passive funds simply aim to mirror a market index, like the Nifty
50 or Sensex. The fund holds the same stocks in the same proportions as the index it tracks. The goal isn't to outperform the market but to match its performance as closely as possible, minus a small fee. This approach, popularised by investment pioneers like John Bogle, operates on the principle that consistently beating the market is incredibly difficult, so it's more efficient to just ride the market's overall growth.
The Decisive Factor: Lower Expense Ratios
The single biggest driver of the shift towards passive funds is the dramatic difference in cost. Every mutual fund charges an annual fee called the Total Expense Ratio (TER), which covers management fees, administrative costs, and other operational expenses. For active funds in India, this fee typically ranges from 1% to 2.5%. In contrast, passive funds, because they don't require expensive research teams or star fund managers, have much lower TERs, often between 0.05% and 0.5%. This might not sound like a huge difference, but over the long term, its impact is enormous. A higher expense ratio directly eats into an investor's returns, and the effect of compounding means that even a 1% difference in annual fees can lead to a significantly smaller corpus over 15 or 20 years.
The Performance Question: Paying More for Less?
Historically, investors were willing to pay higher fees for active funds with the expectation of higher returns. However, data increasingly shows that a majority of active large-cap funds in India struggle to consistently outperform their benchmark indices over the long term, especially after costs are factored in. For many investors, the realisation is setting in that they are paying a premium for active management that often fails to deliver superior performance in the large-cap space. While active managers can still find an edge in less-researched areas like small- and mid-cap stocks, the argument for low-cost passive funds for core large-cap allocations has become very strong. A 2025 survey by Motilal Oswal found that low cost was the primary reason (54% of respondents) for choosing passive funds, followed by diversification and simplicity.
Easier Access and a Nudge from Regulators
The growth of passive investing isn't just about cost and performance; it's also about accessibility and regulation. The rise of digital investment platforms and fintech apps has made it easier than ever for retail investors to discover and invest in low-cost index funds and Exchange-Traded Funds (ETFs). Simultaneously, regulatory moves by the Securities and Exchange Board of India (SEBI) have increased transparency around fund expenses. These regulations, which mandate clearer disclosures of expense structures, help investors make more informed comparisons, further highlighting the cost advantage of passive products. This combination of greater awareness, ease of access, and a supportive regulatory environment has fuelled a massive surge in assets. The assets under management (AUM) for passive funds in India have seen a monumental rise, growing to represent a significant portion of the total mutual fund industry.
Is a Passive Strategy Right for You?
Passive funds are particularly well-suited for long-term investors who are cost-conscious and prefer a straightforward approach to building wealth. They are an excellent choice for beginners who may not have deep market knowledge, as they provide broad market exposure without the need to select individual stocks or fund managers. However, they are not a one-size-all solution. Investors with a higher risk appetite or those who believe in a fund manager's ability to generate alpha (returns above the benchmark) may still prefer active funds, especially in niche sectors. Many financial advisors now recommend a 'core-satellite' approach, using low-cost passive funds for the core of a portfolio (like large-cap exposure) and selectively adding active funds as 'satellites' to target specific opportunities.
