How Mutual Funds Work — NAV, Units, Folio
Definition
The operational mechanics of a mutual fund describe the end-to-end journey of an investor's money — from the moment it leaves their bank account, through unit allotment at prevailing NAV, portfolio management by the fund manager, daily NAV computation, and finally redemption when the investor decides to withdraw. Understanding this flow is essential for every distributor because clients will ask exactly how their money is being handled.
In Simple Words
This is a common client question — here is exactly how the process works. When Anita invests ₹10,000 in a mutual fund, a precise chain of events is triggered. First, the money goes from her bank to the AMC's designated bank account (not the fund manager's pocket — this is crucial). The Registrar and Transfer Agent (RTA) — companies like CAMS or KFintech — processes the transaction, allots units at that day's NAV, and updates Anita's folio. The fund manager then deploys this money into the market per the scheme mandate. Every business day, the custodian marks all securities to market value, the fund accountant calculates the NAV, and AMFI publishes it by 11 PM. Anita can track her investment through the AMC website, the RTA portal (MyCams or KFintech), or her CAS (Consolidated Account Statement) which CAMS sends monthly via email. When Anita wants to redeem, she submits a redemption request, units are cancelled at that day's NAV, and money is credited to her bank within 1-3 business days depending on the fund type.
Real-Life Scenario
Let us trace ₹10,000 from Anita's bank account to her mutual fund folio — step by step: Step 1 — Anita logs into her MFD platform (or visits the AMC website) and places a purchase order for ₹10,000 in HDFC Flexi Cap Fund at 11:30 AM on a Monday. Step 2 — ₹10,000 is debited from her bank account via NACH mandate or UPI. Step 3 — Since she submitted before the 3 PM cut-off, she gets Monday's NAV. Let us say the NAV is ₹50.25. Step 4 — Units allotted = ₹10,000 / ₹50.25 = 199.00 units (rounded to 2 decimal places by most AMCs). Step 5 — The RTA (CAMS, in HDFC MF's case) updates Anita's folio. If she is a first-time investor, a new folio number is created. Step 6 — Anita receives an email confirmation and SMS with the allotment details. Step 7 — The fund manager now has this ₹10,000 as part of the larger pool (say ₹35,000 crore corpus) and deploys it according to the scheme mandate. Step 8 — Next day (Tuesday), the NAV is recalculated. If the portfolio gained 0.5%, the new NAV is ₹50.50 and Anita's 199 units are now worth ₹10,049.50. This entire process happens seamlessly for lakhs of investors every single day — that is the beauty of the mutual fund infrastructure in India.

Summary Notes
The money flow is: Investor → AMC pool → Securities market → NAV reflects gains/losses → Investor can redeem at current NAV
Cut-off time is 3 PM for equity/debt funds and 1:30 PM for liquid/overnight funds — this determines which day's NAV applies
CAMS and KFintech are the two major RTAs in India — they are the backbone of mutual fund operations
CAS is the investor's single-window view of all mutual fund holdings across AMCs — generated monthly by RTAs
Always explain the exact timeline for redemption to clients: T+1 for liquid, T+2 for debt, T+3 for equity funds

Frequently asked questions
Is a mutual fund the same as a stock?
No. A stock represents ownership in a single company, while a mutual fund is a portfolio of many securities. When an investor buys a mutual fund unit, they indirectly own a small fraction of every security in that fund's portfolio. This is why mutual funds offer built-in diversification that a single stock cannot.
Who manages the money in a mutual fund?
A qualified fund manager employed by the AMC manages the fund. The fund manager decides which securities to buy, hold, or sell based on the scheme's investment objective. They are supported by a research team of analysts. SEBI mandates that fund managers must have relevant qualifications and experience.
Is my money safe in a mutual fund? What if the AMC shuts down?
Mutual fund assets are held by a custodian (like a bank), not by the AMC itself. Even if the AMC shuts down, investor money is safe because it is ring-fenced from the AMC's own finances. SEBI would either transfer the scheme to another AMC or return the money to investors at prevailing NAV. This is a critical point clients frequently ask about — and the NISM exam tests this.
What is the difference between NAV and market price?
NAV is calculated once a day after market close (except for ETFs which trade real-time). Unlike stocks that have a fluctuating market price throughout the day, mutual fund units are bought and sold at the day-end NAV. If a purchase is submitted before the cut-off time (usually 3 PM for equity funds), that day's NAV applies.
How much money is needed to start investing in mutual funds?
A lump sum investment can begin with as little as ₹1,000 and a SIP with just ₹500/month (some AMCs allow ₹100). This low entry point is one of the biggest advantages of mutual funds compared to real estate or direct equity portfolios, which need much larger amounts.
What happens if I invest after the 3 PM cut-off time?
If an investor places an order in an equity or debt fund after 3 PM, the next business day's NAV applies, not the current day's. For liquid and overnight funds, the cut-off is 1:30 PM. This is a SEBI regulation and applies uniformly to all AMCs. The NISM exam specifically tests cut-off time rules — these must be memorized.
What is a CAS and how is it different from an account statement?
CAS (Consolidated Account Statement) is a single document showing all mutual fund holdings across all AMCs, linked to the investor's PAN. It is generated by the RTAs (CAMS/KFintech) and emailed monthly if there have been transactions. An account statement, on the other hand, is from a single AMC showing only that AMC's holdings. CAS gives the complete picture.
What is the role of the RTA?
The RTA (Registrar and Transfer Agent) is the back-office engine of the mutual fund industry. CAMS and KFintech are the two major RTAs in India. They process investor transactions, maintain folio records, issue account statements, handle KYC verification, and generate the CAS. Think of them as the "operations backbone" of mutual funds.
