Direct vs Regular Mutual Fund SIP – The 15-Lakh Corpus Difference

What SEBI Actually Created in 2013

In January 2013, the Securities and Exchange Board of India (SEBI) directed every open-ended mutual fund to offer two parallel "plans" of the same scheme — a Regular Plan and a Direct Plan. The portfolios are identical. The fund manager, the underlying stocks, the bonds, the AUM — all the same. The only difference is the Total Expense Ratio (TER) charged annually. The Direct Plan has no distribution commission baked in; the Regular Plan does.

For more than a decade now, both plans have run side by side. And yet, a 2024 AMFI investor research note noted that a majority of Indian retail mutual fund AUM still sits in regular plans. The reason is not pricing — it is awareness. Most first-time investors went through a bank RM or distributor app, never saw the direct option, and never knew they were paying.

How the TER Gap Works Under the Hood

Every mutual fund deducts a daily proportional charge from NAV to cover fund management, administration, and (in the regular plan) the trail commission paid to the distributor for as long as you stay invested. The trail commission typically runs at 0.6%–1.2% per year for actively managed equity funds.

Two consequences follow from "daily, proportional":

• The TER gap applies to your entire corpus, not just to new SIP installments. As your corpus grows, the rupee value of the gap grows with it.
• You never see the deduction. It is silently embedded in NAV. There is no line item on your statement saying "₹X paid as commission this month."

This is why investors underestimate the cost. A 1% TER gap "sounds small" but compounds geometrically against your wealth. See the compound interest calculator for the underlying math.

The Real-Money Difference Over 10, 20 and 30 Years

Assume a ₹10,000/month SIP. Regular plan compounds at 11% net (after TER), Direct plan at 12% net. Here is what the gap becomes.

Tenure	Total Invested	Regular Plan Corpus (11%)	Direct Plan Corpus (12%)	Gap
10 years	₹12.0 lakh	₹21.7 lakh	₹23.2 lakh	₹1.5 lakh
15 years	₹18.0 lakh	₹45.8 lakh	₹50.4 lakh	₹4.6 lakh
20 years	₹24.0 lakh	₹86.6 lakh	₹1.00 crore	₹13.4 lakh
25 years	₹30.0 lakh	₹1.55 crore	₹1.90 crore	₹35.0 lakh
30 years	₹36.0 lakh	₹2.71 crore	₹3.49 crore	₹78.0 lakh

At 20 years — the realistic horizon for a 30-year-old building a retirement corpus — the gap is roughly ₹13–15 lakh. That is the headline number for this post. Run your own scenarios on the SIP calculator using two different return rates to see the gap for your numbers.

TER Gap by Fund Category

The TER gap is not the same for every fund. Equity actively managed funds carry the highest commission load; index funds carry almost none. Here are illustrative TER ranges based on AMFI's January 2026 disclosures.

Fund Category	Typical Regular TER	Typical Direct TER	Gap
Large Cap Equity	1.6%–1.9%	0.5%–0.9%	~1.0%
Flexi Cap Equity	1.7%–2.0%	0.6%–1.0%	~1.0%
Mid & Small Cap Equity	1.8%–2.1%	0.7%–1.1%	~1.0%
Aggressive Hybrid	1.6%–1.9%	0.6%–1.0%	~1.0%
Nifty 50 Index Fund	0.4%–0.8%	0.1%–0.2%	~0.4%
ELSS (Tax-saving)	1.7%–1.9%	0.6%–1.0%	~1.0%
Short-Duration Debt	0.8%–1.2%	0.2%–0.4%	~0.6%
Liquid Fund	0.3%–0.5%	0.1%–0.2%	~0.2%

Notice that for index funds the absolute TER is already low, so the regular-vs-direct gap is also smaller in absolute terms. But percentage-wise, paying 0.6% instead of 0.15% is still a 4x overcharge on a passive product that does the same thing in both plans.

When Regular Plans Are Actually Justified

To be fair to distributors: regular plans are not automatically bad. They are bundled advice products. The 1% trail compensates a human (or a hybrid robo-advisor) for hand-holding through:

• Goal mapping and risk profiling
• Asset allocation between equity and debt
• Behavioural coaching during market crashes (the most under-rated value)
• Periodic portfolio reviews and rebalancing nudges
• Paperwork — nomination, redemption, tax statements, inheritance

If you genuinely use those services and they prevent even one panic exit during a 30%+ drawdown, the 1% trail can pay for itself many times over. The catch: many "advisors" do none of this. They sell you a fund, take the trail forever, and never speak to you again. If that's your experience, you are paying for a service you don't receive.

How to Switch from Regular to Direct (Without Tax Damage)

Switching from a regular plan to the direct plan of the same scheme is treated as a redemption + fresh purchase under Indian tax law. That triggers:

• Exit load (if you switch within the load period, usually 1 year for equity)
• Capital gains tax on the realised portion
• STCG (20%) for units held under 12 months, LTCG (12.5% beyond ₹1.25 lakh) for units held over 12 months

Three smart-switching tactics minimise the damage:

1. Stop new regular SIPs immediately. Open a direct SIP for fresh money in the same fund. This stops the bleed without triggering any tax.
2. Switch units that are LTCG-eligible in tranches. Use your ₹1.25 lakh LTCG exemption window each financial year to switch a portion tax-free.
3. Time switches around market dips. Realising losses on units in red is tax-free (and you can carry forward the loss). Realising gains during a correction means smaller tax bills.

For multi-AMC portfolios, MF Central or any RTA portal (CAMS/KFintech) lets you initiate direct-plan SIPs in seconds with your existing folio.

Five Myths Distributors Tell You

Myth 1: "Direct plans don't have customer service."

Direct plans use the same AMC support, same RTA (CAMS/KFintech), same call centres. Customer service is on the AMC's books — not the distributor's.

Myth 2: "Direct plans have lower returns because they exclude the best funds."

Every scheme that has a regular plan must have a direct plan by SEBI regulation. The portfolios are mathematically identical. The direct plan NAV is always equal to or higher than the regular plan NAV of the same scheme on every single day since 2013.

Myth 3: "Switching to direct will trigger a huge tax bill."

Only on realised gains. With staged switching across financial years and the ₹1.25 lakh LTCG exemption, most retail investors can complete a full switch over 2–3 years with negligible tax — and recover any tax paid within 12–18 months from the lower TER.

Myth 4: "Index funds are cheaper, so direct doesn't matter."

Index funds have a smaller TER gap (~0.4%) but it's a higher multiple. Paying 0.6% on a passive product when the direct version costs 0.15% means you are giving up 4x the necessary expense ratio for the same returns.

Myth 5: "You need expertise to manage direct plans."

Direct plans don't require expertise — they require five clicks. Fund selection complexity is identical in both. If you can use a banking app, you can run direct SIPs.
