Flexi Cap vs Multi Cap Funds: SEBI Rules and Who Each Suits

The difference is a single rule. A flexi cap fund must keep at least 65% of its assets in equity but can divide that across large, mid and small companies however the manager likes. A multi cap fund must hold at least 25% each in large, mid and small caps, so at least half of it is always in mid and small companies. That makes multi cap funds typically more volatile, with more room to grow, and flexi cap funds more dependent on the manager's judgement.

Rules in this article are as of October 2026. Return figures are illustrative assumptions, not forecasts; past returns do not guarantee future returns.

SEBI's rules for each category

SEBI's mutual fund categorisation framework defines company size by rank, using AMFI's half-yearly list of companies by full market capitalisation: large caps are the top 100, mid caps rank 101 to 250, and small caps rank 251 onwards. The category rules then set how much each fund must hold. SEBI's circular of 26 February 2026 on categorisation and rationalisation raised equity minimums for some categories, such as value, contra, focused and dividend yield funds, but left these two unchanged.

Multi cap funds in their current form date from SEBI's 2020 changes, which introduced the 25-25-25 rule. Many existing multi cap funds then moved into the newly created flexi cap category to keep their freedom, which is why flexi cap is today the larger of the two.

For the size definitions in detail, see large cap vs mid cap vs small cap funds.

How each behaves when markets move

Because a multi cap fund must keep at least 25% in small caps and 25% in mid caps, it tends to rise more in broad rallies led by smaller companies and fall harder in sell-offs that hit them. A flexi cap fund's behaviour depends on what its manager holds; many keep a majority in large caps, but nothing stops one from shifting heavily into mid and small caps.

Worked example: the same fall, two portfolios

Take two ₹10 lakh portfolios, both fully in equity for simplicity:

• Flexi cap (typical large-cap tilt): 65% large, 25% mid, 10% small.
• Multi cap (near the minimums): 40% large, 30% mid, 30% small.

Suppose, as a hypothetical scenario, large caps fall 10%, mid caps 20% and small caps 30%.

The multi cap portfolio loses 4.5 percentage points more in this fall. In a rally led by smaller companies the pattern can reverse. Neither is better in every year; the question is which pattern you can sit through without selling at the bottom.

A SIP view of the same choice

For a long SIP, the category's average return over time matters more than any single fall, and nobody can know it in advance. As an illustration, a ₹10,000 monthly SIP for 15 years (₹18 lakh invested) at an assumed annual return compounded monthly:

• At 10%: i = 0.10 ÷ 12, n = 180, FV ≈ ₹41,79,243
• At 12%: i = 0.01, (1.01)^180 = 5.9958, FV = ₹10,000 × [(5.9958 − 1) ÷ 0.01] × 1.01 ≈ ₹50,45,760

The ₹8.7 lakh gap shows how much two percentage points a year matter over 15 years, but there is no rule that either category delivers the higher figure. Use the SIP calculator to test your own assumptions.

Which suits whom

In short:

• Flexi cap suits investors who want a single diversified equity fund and are comfortable trusting the manager to decide the size mix.
• Multi cap suits investors who specifically want guaranteed exposure to mid and small companies and can tolerate larger swings, usually with a long horizon.

What to check before choosing either

1. The actual portfolio, not the label. Look at the latest factsheet for the large, mid and small-cap split. Two flexi cap funds can be very different.
2. Consistency against the benchmark. Flexi cap funds are usually benchmarked to broad indices such as the Nifty 500 or BSE 500; multi cap funds often to a multi cap index weighted 50-25-25. Compare rolling returns against the stated benchmark.
3. Expense ratio. Choose the direct plan if you do not need a distributor. A lower cost is the only return you can be sure of.
4. Overlap with what you already hold. A flexi cap fund plus a large-cap fund may hold the same top 20 stocks. See mutual fund portfolio overlap.
5. Riskometer and fund size. Most diversified equity funds sit in SEBI's "Very High" risk band. A very large multi cap fund may find it harder to deploy money in small caps.

Tax (as of October 2026)

Both are equity-oriented funds. Units held more than 12 months are taxed at 12.5% on long-term gains above ₹1.25 lakh a year; units held 12 months or less at 20%. For a SIP, each instalment has its own holding period, and redemptions follow first-in, first-out. Switching from one category to another is a redemption and can trigger tax.

Key takeaways

• Flexi cap funds must hold at least 65% in equity with no size limits; multi cap funds must hold at least 25% each in large, mid and small caps, as of October 2026.
• SEBI's February 2026 recategorisation left both rules unchanged.
• Multi cap funds usually swing more; in our hypothetical fall, a multi cap mix lost 19.0% against 14.5% for a large-cap-tilted flexi cap mix.
• Flexi cap suits a single core holding; multi cap suits investors who want assured small and mid-cap exposure and a long horizon.
• Check the actual portfolio, cost and overlap, not the label; returns are never guaranteed and tax is the same for both.
