Groww vs Zerodha Coin: Mutual Fund Showdown

For Indian mutual fund investors, Groww and Zerodha Coin are the two largest, most popular platforms. Both are SEBI-registered investment platforms offering regulated, zero-commission Direct Mutual Funds, allowing you to bypass distributors and save up to 1% to 1.5% annually in expense ratios.

However, behind the "free direct funds" marketing, the two platforms have vastly different underlying architectures, fees, and user experiences. In this guide, we break down their differences to help you choose the right platform.

Summary Table: Fees & Features

*Fee structures and account charges are subject to change and reflect official platform schedules as of July 2026.

Key Difference 1: Demat vs. Non-Demat Holding

This is the single most critical structural difference:

• Zerodha Coin holds all mutual funds inside your Demat account (managed by CDSL). Since it is in Demat format, you get a single consolidated statement for your stocks, ETFs, and mutual funds. However, redemptions and setups are bound to Demat transaction times and require active AMC payments.
• Groww holds mutual funds in the traditional Statement of Account (SOA) format via mutual fund registrar agencies like CAMS and KFintech. A Demat account is not required. If you decide to close your Groww account, your mutual funds remain safe and redeemable directly from the AMC websites.

Key Difference 2: Costs and Account Fees

While mutual fund transactions are commission-free on both platforms, account maintenance fees differ:

Groww is 100% free for mutual funds. There are no account opening fees and zero annual maintenance charges (AMC).

Zerodha Coin requires a trading account with Zerodha. Opening this account costs ₹200 (one-time), and maintaining the demat account costs ₹300 per year (billed quarterly as ₹75), regardless of whether you buy stocks or only mutual funds.

Key Difference 3: SIP and Systematic Plans

Due to the Demat architecture, Zerodha Coin processes SIPs using a manual mandate or trading balance. If your Zerodha wallet is empty on the SIP date, your SIP will bounce.

Groww supports standard bank AutoPay mandates (via e-NACH). The SIP amount is pulled directly from your bank account to the fund house, eliminating the need to maintain a wallet balance.

Key Difference 4: Does the Expense Ratio Differ Between the Two?

A common misconception is that expense ratios vary between investment platforms. In reality, a mutual fund's expense ratio is set and charged directly by the Asset Management Company (AMC)—such as HDFC, SBI, or Parag Parikh—not by Groww or Zerodha.

For any given Direct Plan, the expense ratio is 100% identical whether you invest through Groww, Zerodha Coin, or directly via the fund house. Platform choice does not alter this cost. What does differ between the two platforms is account-level charges (such as Demat maintenance fees), not fund-level expense ratios. This is separate from the 1% to 1.5% annual savings mentioned earlier, which compares Direct Plans to distributor-sold Regular Plans rather than Groww to Zerodha Coin.

Downsides to Consider

Neither platform is without trade-offs. Consider the following platform-specific downsides:

Zerodha Coin Downsides:

• Mandatory Demat overhead: Requires opening and managing a full Demat and trading account, adding unnecessary operational steps for pure mutual fund investors.
• Account Maintenance Charges (AMC): Incurs ₹300/year + GST in Demat maintenance fees, even if you never trade stocks and only hold mutual funds.
• Wallet balance & mandate dependency: SIPs rely on adequate funds in your Zerodha trading balance or specific mandate schedules, which can fail if funds are not maintained on time.

Groww Downsides:

• No Demat portfolio consolidation: Mutual funds are held in Statement of Account (SOA) format, meaning they are not consolidated inside a single CDSL/NSDL Demat statement alongside Demat stocks or ETFs.
• Fragmented portfolio tracking: If you trade equities across separate stockbrokers in Demat format, your mutual fund holdings remain tracked separately via RTAs (CAMS/KFintech).

Verdict: Which Should You Choose?

Choose Groww if: You want a 100% free platform, do not want the hassle of Demat accounts, prefer seamless direct-from-bank auto-SIP processes, and want an intuitive interface focused purely on mutual funds.

Choose Zerodha Coin if: You are already an active stock trader using Zerodha Kite and prefer consolidating your entire stock, ETF, and mutual fund portfolio in a single Demat view.
