Direct vs regular mutual funds — the exact difference in returns over 10 years in India

Every mutual fund in India offers two versions of the same scheme: a direct plan and a regular plan. They invest in identical portfolios, are managed by the same fund manager, and carry the same investment objective. The only difference is cost. But that cost difference, compounded over 10 years, produces a gap in your final corpus that most investors would find genuinely shocking the first time they calculate it.

What the two plans actually are

A regular plan is one where you invest through a distributor — a bank, a mutual fund agent, an online platform that earns commission, or a relationship manager. The fund house pays the distributor a trail commission, typically ranging from 0.5% to 1.25% per annum depending on the fund category. This commission is embedded in the scheme's expense ratio, which means you pay it every year as a percentage of your invested corpus without receiving a separate bill for it.

A direct plan is one where you invest directly with the fund house — through the AMC's own website, through SEBI-registered investment advisers, or through platforms like MF Central, Kuvera, or Coin by Zerodha that do not earn distributor commissions. Because there is no distributor in the chain, the expense ratio is lower by exactly the amount of the distributor's commission. The NAV of the direct plan is therefore higher than the NAV of the regular plan in the same scheme on any given day, and it compounds at a marginally faster rate every single year.

The numbers: what the gap looks like in practice

Take a large-cap equity fund with a regular plan expense ratio of 1.5% and a direct plan expense ratio of 0.7% — a difference of 0.8 percentage points, which is realistic for this category. Assume the fund generates a gross return of 12% per annum before expenses.

Regular plan net return: 12% minus 1.5% = 10.5% per annum. Direct plan net return: 12% minus 0.7% = 11.3% per annum.

Now invest ₹10,000 per month as a SIP in each plan for 10 years.

At 10.5% annualised return, your ₹12,00,000 of total investment grows to approximately ₹20,87,000. At 11.3% annualised return, the same ₹12,00,000 grows to approximately ₹21,98,000.

The difference is approximately ₹1,11,000 — on a total investment of ₹12 lakh over 10 years. That is nearly one year's worth of SIP instalments lost purely to the cost differential between two plans that invest in exactly the same stocks.

Extend the horizon to 20 years and the compounding effect becomes dramatically larger. At 10.5%, ₹10,000 per month for 20 years grows to approximately ₹78,39,000. At 11.3%, the same SIP grows to approximately ₹88,06,000. The gap is now approximately ₹9,67,000 — nearly 10 lakh rupees on a total investment of ₹24 lakh, entirely attributable to the expense ratio difference.

For actively managed mid-cap or small-cap funds, where the expense ratio difference between direct and regular plans can be as wide as 1-1.25 percentage points, the gap over 20 years on the same SIP would exceed ₹15-20 lakh.

Why most investors are still in regular plans

Despite the mathematical clarity of the direct plan advantage, the majority of Indian mutual fund assets — roughly 45-50% of retail folios by some industry estimates — remain in regular plans. The reasons are straightforward.

The first is distribution reach. Banks, relationship managers, and agents actively sell regular plans because that is how they earn their livelihood. The direct plan requires the investor to take initiative, which most people either do not have the time for or do not know is an option. The second is the advisory value question — if a distributor is actively guiding your asset allocation, reviewing your portfolio, and helping you stay invested during volatile markets like the current one, there is a genuine argument that the trail commission they earn is fair compensation for that service. The problem is that most distributors in India are not providing that level of service — they are collecting trail commission on autopilot after the initial sale.

The third reason is inertia. Switching from a regular to a direct plan requires redemption from the regular plan and fresh investment in the direct plan — a process that can trigger exit load if done within the exit load period, and capital gains tax if your investment has appreciated. For investors with large existing regular plan corpora, the switching cost needs to be weighed against the future saving.

When regular plans make sense

Regular plans are not universally wrong. If you are a first-time investor with no knowledge of asset allocation, fund selection, or portfolio rebalancing, paying a trail commission to a SEBI-registered mutual fund distributor who actively manages your financial plan may deliver better outcomes than a poorly chosen direct plan portfolio that you abandon during the next market crash. A 0.8% annual cost is cheap insurance against making a ₹5 lakh lump sum investment in a sectoral fund at the wrong time.

The key distinction is between distributors who earn their commission through active, ongoing advisory engagement versus those who make a sale and disappear. The former may justify the regular plan cost; the latter definitely does not.

How to switch to direct plans

If you decide to move existing investments to direct plans, the cleanest approach is to stop the SIP in the regular plan, allow the existing units to complete the exit load period, redeem after one year, and start a fresh SIP in the direct plan of the same fund. This avoids exit load but does attract capital gains tax on the appreciated amount — short-term capital gains at 20% if redeemed within one year, long-term capital gains at 12.5% on gains above ₹1.25 lakh per year if held beyond one year.

For new investments, the decision is straightforward: go direct from day one. The platforms that facilitate direct plan investing — MF Central, AMC websites, Kuvera, Coin, Groww's direct plan option — are accessible, straightforward, and charge nothing for the transaction.

The 0.8 percentage point difference between direct and regular plans is not large enough to notice in any single month's statement. But compounded over the 10-20 year horizons that make equity mutual funds worth investing in, it produces a difference in final corpus that runs into multiple lakhs of rupees on a modest SIP. That is money that belongs in your retirement corpus, not in a distributor's trail commission account.
