The Hidden Cost of Going Direct: How Investors Could Be Losing Up to 3% a Year
By Inderpreet Singh, QPFP · NISM Certified Investment Advisor L1 · Updated September 2026 · 11 min read
A well-known Vanguard study estimates that a good financial advisor can add up to 3% in net returns annually, primarily through behavioural coaching, helping investors avoid the panic-selling and performance-chasing that quietly erode most portfolios' actual returns. That single number is larger than the entire expense ratio difference between a direct and a regular mutual fund plan. This article walks through exactly where that 3% comes from, then the honest expense-ratio math, so you see the full picture, not just the part that fits neatly on a comparison chart.
What this article is really about
Direct plans cost 0.3 to 0.7% less per year in expense ratio than regular plans. That's real and worth knowing. But global research on advisor value suggests the behavioural discipline a good MFD provides, staying invested through corrections, not chasing last year's winner, can be worth up to 3% a year on its own. The real question isn't which plan is cheaper. It's whether you're equipped to capture the larger number without help.
1. Global Research Puts a Number on Behavioural Coaching
Vanguard, one of the largest asset managers in the world, has studied the question of what an advisor is actually worth through its well-known "Advisor's Alpha" research. Its consistent finding across multiple editions of the study: behavioural coaching, essentially, an advisor helping an investor stay the course rather than panic-sell or chase last year's winner, may add 100 to 200 basis points in annual returns on its own, described by Vanguard as potentially "the largest potential value-add of the tools available to advisors," larger than fund selection, cost-effective implementation, or any other single factor measured.
| Advisor's Alpha Component | Category | Potential Value Added |
|---|---|---|
| Suitable asset allocation | Portfolio construction | Present, not separately quantified |
| Cost-effective implementation | Portfolio construction | 0.30% |
| Asset location | Portfolio construction | 0 to 0.60% |
| Total-return vs income investing | Portfolio construction | Present, not separately quantified |
| Rebalancing | Wealth management | Up to 0.14% |
| Spending strategy (withdrawal order) | Wealth management | Up to 1.20% |
| Behavioural coaching | Wealth management | 1.00% to 2.00% |
| Total potential value added | Up to, or even exceed, 3% | |
Source: Vanguard, "Putting a Value on Your Value: Quantifying Vanguard Advisor's Alpha" (Kinniry, Jaconetti, DiJoseph, Walker, Quinn, July 2022 edition). US market research. The total is Vanguard's own holistic estimate, not a literal sum of the rows above, see note below.
Vanguard puts the total potential value of working with a good advisor at up to, or even exceeding, 3% in net returns annually. Look at where most of that 3% actually comes from: behavioural coaching alone can be worth as much as every other quantified component in the table combined.
Worth being precise about what this is and isn't. This research is built on US market data, not an Indian study, and investor behaviour, fund structures, and market dynamics differ between the two markets. Vanguard itself notes it has separately estimated similar frameworks using non-US data over multiple time periods with broadly comparable results, though the exact value of each individual practice still varies by local tax laws, regulations, and market structure. Vanguard also cautions that its individual component figures should not simply be added together, since the different sources of value interact with each other, and it explicitly states this potential value-add is unlikely to arrive as a steady annual figure, it tends to show up unevenly, often concentrated in the market's most difficult or euphoric moments. It is not a promise that any specific advisor adds a specific percentage to any specific portfolio. What it is: a data point from one of the most credible, data-driven asset managers globally, and the question worth asking next is whether India's own data shows anything similar.
2. It Does. The Behaviour Gap, By the Numbers: How Long Do SIPs Actually Stay Invested?
That's global research, built on US data. Closer to home, AMFI's own holding-period breakdown of Indian SIP assets shows a strikingly similar pattern: money in direct plans moves in and out far more often than money in regular plans held through an MFD.
| SIP Holding Period | Direct Plan (Share of AUM) | Regular Plan (Share of AUM) |
|---|---|---|
| Greater than 5 years | 9% | 19% |
| 1 to 2 years | 25% | 22% |
| Less than 1 year | 41% | 31% |
Source: AMFI SIP holding-period data. Figures are share of total SIP AUM in each category, not number of investors.
Two numbers stand out. Regular plan investors are more than twice as likely to still be holding their SIP after 5 years, 19% of regular plan assets versus 9% of direct plan assets. And direct plan money is meaningfully more likely to exit within the first year, 41% versus 31% for regular plans. In an asset class where the biggest driver of outcomes is usually staying invested through the boring, uneventful middle years, that gap in patience is arguably more valuable than the expense ratio saving it's often traded against.
To be fair to the data: this doesn't prove the MFD relationship alone causes longer holding periods. Investors who choose direct plans may also be a different population to begin with, more fee-conscious, more comfortable managing things themselves, sometimes younger and still building conviction in a buy-and-hold approach. Correlation isn't proof of causation. But it is consistent with the core argument of this article, and with Vanguard's own research above: an advisor's real value often shows up not in fund selection, but in simply keeping people invested when their instincts say otherwise.
3. What This Actually Looks Like: The Costs That Do Not Appear on the Expense Ratio
None of this is abstract theory. Research consistently shows that individual investors underperform the very funds they invest in, due to behaviour, not fund selection. This gap is called the behaviour gap, and it's worth seeing what it actually looks like in practice.
| Behavioural Mistake | Estimated Cost |
|---|---|
| Panic selling in a bear market | 20 to 40% permanent loss if exited at bottom and re-entered late |
| Chasing recent top performers | Consistently underperforms disciplined SIP by 3 to 5% annually |
| Over-diversification (20 plus funds) | Returns converge to index, minus a higher total expense ratio |
| Stopping SIPs when market falls | Missing the best accumulation period, exactly when SIPs should continue |
| No rebalancing | Portfolio drifts from target allocation, often 80% equity by late bull market |
A good MFD's most valuable service is not fund selection, it is preventing these mistakes. If your MFD stops you from selling in one bear market, they have more than earned a decade of trail commission.
4. So What About the Expense Ratio Savings? They're Real, Just Smaller Than the Number Above
| Fund Category | Direct TER | Regular TER | Annual Difference |
|---|---|---|---|
| Large Cap Fund | 0.50 to 0.80% | 0.90 to 1.20% | 0.40 to 0.50% |
| Flexi Cap Fund | 0.60 to 0.90% | 1.00 to 1.50% | 0.40 to 0.60% |
| Mid Cap Fund | 0.70 to 1.00% | 1.20 to 1.70% | 0.50 to 0.70% |
| Small Cap Fund | 0.80 to 1.10% | 1.30 to 1.80% | 0.50 to 0.70% |
| Debt Fund (Short Duration) | 0.20 to 0.40% | 0.50 to 0.80% | 0.30 to 0.40% |
| Index Fund (Nifty 50) | 0.10 to 0.20% | 0.30 to 0.50% | 0.20 to 0.30% |
TER ranges are indicative. Actual TERs vary by fund and AUM. Check current TERs on AMFI website before investing.
The long-term compounding impact, at its absolute best case
On a Rs 1 crore portfolio earning 12% (direct) vs 11.5% (regular, assuming 0.5% difference): over 20 years, direct grows to Rs 9.65 crore and regular to Rs 8.85 crore, a difference of Rs 80 lakh. This is the maximum possible advantage of direct, and it assumes identical decisions and zero behavioural cost, exactly the assumption the research above suggests rarely holds.
When Direct Makes Sense
You have strong financial knowledge and actively research funds
You can build and maintain a well-diversified portfolio independently
You will not panic-sell during a 30 to 40% market correction
You have the time to monitor portfolio drift and rebalance annually
You do not need tax planning, goal mapping, or insurance integration
Your portfolio is simple (2 to 3 index funds, no complex goals)
When an MFD Makes Sense
You are new to investing and need guidance on fund selection and allocation
You have multiple goals (retirement, education, home) requiring coordinated planning
You need insurance review, tax planning, and investment advice from one advisor
Your portfolio is large enough that the cost of a mistake exceeds the expense ratio saving
You have limited time to track markets, rebalance, and make informed switches
Behavioural coaching (staying invested in corrections) is valuable to you
What a Good MFD Should Provide
If you use an MFD, you should expect, and demand, more than fund selection:
- Goal-based financial planning (retirement, education, home)
- Portfolio review at least once a year
- Rebalancing recommendations when allocation drifts
- Tax-loss harvesting and capital gains management at year-end
- Insurance review: term, health, and motor aligned to your life stage
- Behavioural guidance during market corrections, preventing panic decisions
An MFD who only processes SIPs and does not provide these services is not earning their trail commission. The relationship should feel like a financial co-pilot, not a transaction processor.

The Bottom Line
Direct plans are the right choice if you have the knowledge, discipline, and time to manage your own portfolio well. Regular plans via a good MFD are the right choice if you value advice, planning integration, and behavioural guardrails, and if the MFD earns the commission through genuine service.
The worst outcome is investing in regular plans via an MFD who provides no service. The second-worst is investing in direct plans and making behavioural mistakes that cost more than the expense ratio saving.
Choose based on your honest assessment of your own knowledge, discipline, and time, not just the expense ratio comparison. This same discipline shows up clearly in the data on women investors specifically, see why Indian women invest more but still own less wealth.
