Direct Plan Vs Regular Plan: The Real Cost Gap Over 20 Years, With Numbers

A Direct Plan and a Regular Plan of the same mutual fund scheme hold the same securities, are run by the same fund manager, and follow the same investment strategy. Nothing about the underlying portfolio changes based on which plan you choose.

The only structural difference is that a Regular Plan's expense ratio includes the distributor commission described in our earlier article on trail commission, while a Direct Plan's does not.

That difference shows up in a very specific place: the fund's Net Asset Value. Expenses are deducted from the scheme's assets before the NAV is calculated each day, so a lower expense ratio means a slightly higher daily NAV growth rate, all else equal.

Since the April 2026 shift to the Base Expense Ratio framework, both plans are still subject to the same category cap before the commission is added back for the Regular Plan, so the mechanism has not changed, only the specific ceiling has moved slightly lower across most categories.

The Typical Gap, By Category

Category	Typical Regular Plan Expense Ratio	Typical Direct Plan Expense Ratio	Approximate Gap
Equity oriented schemes	Roughly 1.5% to 2.10%	Roughly 0.5% to 1.2%	Roughly 0.5 to 1.5 percentage points
Debt oriented schemes	Roughly 1.0% to 1.85%	Roughly 0.3% to 0.8%	Roughly 0.3 to 1.0 percentage points
Index and other passive schemes	Up to 0.90%	Often 0.1% to 0.3%	Roughly 0.1 to 0.6 percentage points

Figures are typical ranges observed across the industry, not a single published rate. Larger schemes generally sit toward the lower end of the Regular Plan range because the Base Expense Ratio caps decline as a scheme's assets grow. The passive category's gap looks small in percentage terms but can represent a large share of that category's thin overall cost budget.

Turning A Percentage Gap Into A Rupee Number

To see what a modest looking gap does over time, assume a lump sum investment of Rs 10,00,000 in an equity oriented scheme, with a hypothetical net return of 11.5% a year in the Direct Plan and 10.5% a year in the Regular Plan, a 1 percentage point gap roughly in the middle of the typical equity range shown above. Both figures are illustrative assumptions, not return forecasts.

Year	Direct Plan Corpus	Regular Plan Corpus	Gap
5	Rs 17,23,353	Rs 16,47,447	Rs 75,907
10	Rs 29,69,947	Rs 27,14,081	Rs 2,55,866
15	Rs 51,18,268	Rs 44,71,304	Rs 6,46,964
20	Rs 88,20,584	Rs 73,66,235	Rs 14,54,349

Hypothetical illustration only, assuming a one time investment of Rs 10,00,000 growing at 11.5% a year in the Direct Plan and 10.5% a year in the Regular Plan, with no withdrawals. By year 20, the gap equals close to 20% of the Regular Plan corpus, even though the underlying assumed return gap was only 1 percentage point a year.

The gap does not grow in a straight line. In the first five years it is a relatively small Rs 75,907, under 5% of the Regular Plan corpus. By year 20, the same 1 percentage point annual difference has produced a gap of Rs 14,54,349, essentially a fifth of the entire Regular Plan corpus. This is compounding working on the cost difference itself, not just on the investment.

A gap of one percentage point a year sounds trivial. Compounded over two decades, it becomes a fifth of the corpus you actually retire with.

The Same Math For A Monthly SIP

Lump sum investing is not how most people actually build a mutual fund portfolio. Running the same 1 percentage point gap through a monthly Systematic Investment Plan of Rs 10,000, instead of a one time lump sum, tells a similar story, even though each individual contribution has less time to compound than the first one did.

Year	Amount Invested	Direct Plan Corpus	Regular Plan Corpus	Gap
10	Rs 12,00,000	Rs 22,55,442	Rs 21,26,594	Rs 1,28,847
15	Rs 18,00,000	Rs 48,10,828	Rs 43,78,276	Rs 4,32,552
20	Rs 24,00,000	Rs 93,39,666	Rs 81,75,968	Rs 11,63,698

Hypothetical illustration only, assuming a Rs 10,000 monthly SIP growing at 11.5% a year in the Direct Plan and 10.5% a year in the Regular Plan. By year 20, the gap of Rs 11,63,698 is close to half of the entire Rs 24,00,000 actually invested over those two decades.

How Much The Assumed Gap Itself Matters

The 1 percentage point assumption used above sits in the middle of the typical equity range, but actual gaps vary by scheme. Holding the Direct Plan return fixed at a hypothetical 11% a year over 20 years on the same Rs 10,00,000 lump sum, a wider or narrower assumed gap changes the year 20 shortfall considerably.

Assumed Annual Gap	Regular Plan Return Used	Regular Plan Corpus At Year 20	Shortfall Versus Direct Plan
0.5 percentage points	10.5%	Rs 73,66,235	Rs 6,96,077
1.0 percentage points	10.0%	Rs 67,27,500	Rs 13,34,812
1.5 percentage points	9.5%	Rs 61,41,612	Rs 19,20,699

All rows assume the Direct Plan grows at a hypothetical 11% a year over 20 years on a Rs 10,00,000 lump sum, so the Direct Plan corpus is the same Rs 80,62,312 throughout. Only the assumed Regular Plan gap changes. A wider gap does not just cost proportionally more, the shortfall as a share of the Regular Plan corpus rises from roughly 9% to more than 31% as the annual gap moves from 0.5 to 1.5 percentage points.

What Does Not Change Between The Two Plans

Taxation is identical either way. The same holding period rules and the same equity oriented capital gains treatment, short term at 20% within 12 months and long term at 12.5% above Rs 1.25 lakh a year beyond that, apply to a Direct Plan and a Regular Plan of the same scheme without any difference. Choosing Direct over Regular is a cost decision, not a tax decision, and it does not change what securities the fund holds or how it is managed.

It is also worth being clear about what the Regular Plan's extra cost is actually paying for. A distributor typically provides ongoing service, guidance on fund selection, help with paperwork, and periodic portfolio reviews, funded by the trail commission built into that expense ratio.

A Direct Plan investor either manages all of this without that support or pays a fee only adviser separately for it. Whether the gap shown above is worth paying depends entirely on how much of that service an individual investor actually uses, not on the numbers alone.

Note: The return rates used in this article are hypothetical assumptions chosen to illustrate how an expense ratio gap compounds, not a forecast, a promise, or a historical average of any actual scheme. Real fund returns vary year to year and can be negative. What this article isolates is a single variable, the cost difference between two plans of the same scheme, while holding the assumed gross return identical between them. Nothing here should be read as a return projection for your own investment.
