How to do a lump-sum mutual fund purchase on Coin

A lump-sum purchase on Zerodha Coin is a one-time investment of a specified rupee amount into a direct plan mutual fund scheme. Unlike a Systematic Investment Plan (SIP), a lump-sum order is a single transaction and does not create any recurring debit obligation. All units purchased through Coin are held in demat account form at CDSL, not in a statement-of-account folio with the fund’s registrar.

This guide explains how to place and confirm a lump-sum purchase on Coin, the NAV cut-off rules that determine the applicable price, and what to verify afterwards.

Prerequisites

• An active Zerodha trading and demat account with full KYC complete under SEBI KRA norms.
• A bank account linked to Zerodha with sufficient funds for the purchase.
• UPI handle registered on that bank account, or access to net banking.
• TOTP (time-based one-time password) set up for Zerodha login.

No separate Coin account is required. Your Zerodha login credentials work on coin.zerodha.com and the Coin mobile app.

Lump-sum vs. SIP: when to use each

A lump-sum purchase is appropriate when you have a specific sum available for immediate deployment – for example, a bonus, a matured deposit, or a planned rebalancing. How to start an SIP on Coin covers periodic automated investment.

A key difference in tax treatment: a lump-sum purchase creates one acquisition lot with a single date and NAV. An SIP creates multiple lots (one per instalment). The holding period for long-term capital gains (LTCG) classification is calculated individually per lot.

NAV cut-off rules

The NAV applied to a lump-sum purchase depends on when funds are received in the AMC’s settlement account, not merely when the order is placed on Coin. SEBI prescribes the following cut-off times under SEBI (Mutual Funds) Regulations, 1996, and related circulars:

Coin’s payment gateway (UPI or net banking) typically settles within the same business day, but initiating a payment close to the cut-off time carries risk of receiving the next day’s NAV. Settle payments at least 30 minutes before the stated cut-off to avoid the rollover.

Step-by-step procedure

Step 1: Log in to Coin

Open coin.zerodha.com in a browser or launch the Coin mobile app. Enter your Zerodha client ID, password, and six-digit TOTP. The Coin dashboard loads your portfolio summary and shows a search bar at the top.

Step 2: Search for the scheme

Enter the fund name, AMC, or a descriptive category term in the search bar. For example, searching “Parag Parikh Flexi Cap” or “flexi cap direct” returns matching schemes. Results include the one-year return, AUM, and direct-plan expense ratio for each fund in the list.

Step 3: Review the fund detail page

Click the scheme name to open the fund detail page. Before placing any order, review:

• Scheme type and category: SEBI’s scheme categorisation (for example, Large Cap, Multi Cap, Gilt Fund) constrains what the fund can invest in.
• Expense ratio (TER): The direct plan TER is lower than the regular plan TER by the trail commission amount. For index funds, compare the TER to the benchmark’s tracking error figure.
• Minimum lump-sum amount: Shown under “Min Purchase” for the initial purchase, and “Min Additional Purchase” for subsequent purchases into an existing folio/demat holding.
• NAV: Current NAV displayed in real time during market hours; updated at end of day post-market close.

Step 4: Initiate the lump-sum order

On the fund detail page, click the Invest button. This opens the one-time purchase form. Do not click the SIP button unless you intend to set up a recurring investment.

In the form, enter the rupee amount. Ensure the amount equals or exceeds the fund’s minimum purchase. Click Invest to advance to the payment screen.

Step 5: Complete payment

UPI: Enter your UPI VPA (Virtual Payment Address). Coin sends a collect request to your UPI app. Switch to the app, locate the pending request, review the beneficiary name and amount, and approve using your UPI PIN. The collect window is typically 5 minutes.

Net banking: You are redirected to your bank’s net banking login. After authentication, confirm the payment. The page redirects back to Coin with a success or failure message.

For amounts over Rs 1 lakh, UPI may not be available depending on your bank’s per-transaction limit. Use net banking in such cases. Some banks support higher UPI limits for mutual fund transactions on NPCI’s agreed-framework platforms; check with your bank.

Step 6: Order confirmation

Coin displays a confirmation screen with:

• Fund name
• Amount invested
• Transaction reference number (useful for grievance filing if needed)
• NAV date applicable (today’s date if before cut-off; next business day if after cut-off)

This confirmation is also visible under Orders in the Coin dashboard (Portfolio > Orders).

Step 7: Post-settlement verification

Mutual fund units are credited to your CDSL demat account after settlement:

• Equity, hybrid, and debt funds (non-liquid): T+2 business days after the NAV date.
• Liquid and overnight funds: T+1 or faster.

After settlement, open Zerodha Console and navigate to Holdings. The fund appears in the list with the unit quantity, average NAV, current NAV, and unrealised gain or loss. The same units are reflected in your monthly CDSL Consolidated Account Statement (CAS) and in the CDSL Demat Account Passbook on cdsl.com.

What can go wrong

Payment gateway timeout: If the UPI collect window expires before approval, the order is cancelled. The amount is not debited. Retry the purchase.

Order placed after cut-off time: Your payment is processed, but the applicable NAV is the next business day’s NAV. This is not an error; it is the standard SEBI cut-off rule. The unit quantity you receive will differ from what was shown at the time of order.

Bank debit but units not credited after T+2: Contact Zerodha support with the transaction reference number. In rare cases the payment is received after the cut-off, creating a one-day delay in allotment.

Minimum amount error: If you enter an amount below the fund’s minimum, Coin blocks submission with an error message. Increase the amount to the stated minimum.

Folio vs. demat holding confusion: Coin holds all units in demat form. If you previously held units in a folio (SOA) through another platform, those are separate and do not appear in Console until imported. See How to import existing mutual funds into Coin.

Tax on lump-sum gains

Gains on a lump-sum purchase are taxed as capital gains based on the date the units were purchased:

• Equity-oriented funds: STCG at 20% for units held under 12 months; LTCG at 12.5% on gains above Rs 1.25 lakh per financial year for units held 12 months or more (Finance Act 2024, effective 23 July 2024).
• Debt-oriented funds (purchased on or after 1 April 2023): Gains taxed at the investor’s income tax slab rate regardless of holding period (Finance Act 2023, section 50AA).
• Debt-oriented funds (purchased before 1 April 2023): Grandfathering provisions may apply; see the grandfathering rule for LTCG.

For tax filing, use Zerodha Console’s Tax P&L statement and refer to ITR-2.
