Mutual Funds Explained: Types, NAV, Expense Ratio and SIP vs Lumpsum for RBI Grade B & Commerce Exams
Mutual Funds in a Nutshell: Direct Exam Answer
Quick answer: A mutual fund is a pooled investment vehicle that collects money from many investors and invests it in a diversified portfolio of securities — equity, debt, or money market instruments — managed by a professional fund manager. In India, mutual funds are regulated by SEBI under the SEBI (Mutual Funds) Regulations, 1996. Key exam terms to master: NAV, AUM, expense ratio (TER), SIP, lumpsum, open-ended vs close-ended funds, and exit load. AMFI is the industry association, not the regulator.

What Is a Mutual Fund? Structure and How It Works
A mutual fund is set up as a trust. Investor money is pooled into a common corpus, units are allotted to each investor in proportion to their contribution, and a professional fund manager deploys the corpus according to the fund’s stated objective.
The four-part structure is a favourite banking-exam question:
- Sponsor — the promoter who establishes the fund (e.g., HDFC, SBI, ICICI).
- Trustee — holds the fund’s assets in trust for unit-holders and oversees the AMC.
- Asset Management Company (AMC) — manages the schemes, makes investment decisions.
- Custodian — holds the securities and handles settlement (registered with SEBI).
Regulatory Framework: SEBI and Key Regulations
The governing law is the SEBI (Mutual Funds) Regulations, 1996, which cover registration, scheme launch, disclosure, and investor protection. The Association of Mutual Funds in India (AMFI) is a self-regulatory industry body — it runs the AMFI Registration Number (ARN) system for distributors and mandates the “Mutual fund investments are subject to market risks” disclaimer. Exam point: SEBI regulates; AMFI is only an industry association. Reference: SEBI and AMFI.
Types of Mutual Funds by Structure: Open-Ended, Close-Ended, Interval
- Open-ended funds — units can be bought and redeemed from the AMC at any time at prevailing NAV. Most funds in India are open-ended.
- Close-ended funds — fixed maturity (typically 3–5 years); units cannot be redeemed from the AMC before maturity, but may be listed and traded on stock exchanges.
- Interval funds — combine both; units can be bought/redeemed only during specified transaction windows.
Types of Mutual Funds by Asset Class: Equity, Debt, Hybrid, Money Market
- Equity funds — invest mainly in stocks. Highest risk, highest potential return. Examples: large-cap, mid-cap, small-cap, ELSS (tax-saving, 3-year lock-in).
- Debt funds — invest in bonds, government securities, corporate debentures. Moderate risk, more stable returns.
- Hybrid funds — mix of equity and debt (e.g., balanced advantage funds). Risk-return in between.
- Money market / liquid funds — very short-term instruments (T-bills, commercial paper, repo). Lowest risk, near-instant liquidity.
Risk-return ordering for exams: Money market < Debt < Hybrid < Equity (risk ascending).
NAV Explained with a Worked Example
NAV (Net Asset Value) is the per-unit price of a mutual fund, declared at the end of each business day.
Formula: NAV = (Total Assets − Liabilities) ÷ Number of Units Outstanding
Worked example: A fund holds securities worth ₹10,00,00,000 (₹10 crore) and cash of ₹50,00,000. It owes ₹10,00,000 in accrued expenses. It has 40,00,000 units outstanding.
- Net assets = ₹10,00,00,000 + ₹50,00,000 − ₹10,00,000 = ₹10,40,00,000
- NAV = ₹10,40,00,000 ÷ 40,00,000 units
- NAV = ₹26 per unit
Expense Ratio, Exit Load and Total Expense Ratio (TER)
The TER is the annual fee a fund charges as a percentage of assets — it covers management fees, administrative costs, registrar charges and distribution costs. It is deducted from the fund’s returns daily, so a high TER directly drags down net returns.
SEBI caps TER on a slab basis for equity funds — roughly 2.25% for the first ₹500 crore of AUM, tapering for larger slabs; debt funds have lower caps. Direct plans carry a lower TER than regular plans because distributor commissions are excluded.
Exit load is a charge levied when you redeem units early — e.g., a 1% exit load within 1 year of investment.
SIP vs Lumpsum: Meaning, Differences and When Each Works
A SIP (Systematic Investment Plan) invests a fixed amount at regular intervals; a lumpsum is a one-time investment. SIP benefits from rupee-cost averaging — you buy more units when NAV is low and fewer when high — and removes timing risk. Lumpsum can outperform if markets rise after entry, but carries full timing risk.
| Feature | SIP | Lumpsum |
|---|---|---|
| Mode | Fixed amount at intervals | One-time |
| Timing risk | Low (averaged) | High |
| Discipline | Builds saving habit | Requires lump availability |
| Best when | Volatile/falling markets, salaried investors | Windfall, bullish outlook |
Key Terminology for Exams: AUM, Units, Folio, Redemption, Load
- AUM — Assets Under Management; total market value of the fund’s holdings.
- Units — the investor’s share of the fund, bought at NAV.
- Folio — the unique account number recording an investor’s holdings in a fund.
- Redemption — selling units back to the AMC at NAV.
- Load — a charge on entry (entry load, banned in India since 2009) or exit (exit load).
Mutual Funds vs Other Investment Avenues
- vs Fixed Deposits: FDs give assured, fixed interest; mutual funds are market-linked with no guaranteed return but higher long-term potential.
- vs PPF: PPF is government-backed, tax-free, 15-year lock-in; ELSS has only a 3-year lock-in and equity-linked returns.
- vs Direct equity: mutual funds offer diversification and professional management at a modest fee; direct equity needs expertise and carries concentrated risk.

Frequently Asked Questions
Q: Who is the regulator of mutual funds in India?
SEBI, under the SEBI (Mutual Funds) Regulations, 1996. AMFI is only the industry association — a classic exam trap.
Q: How is NAV of a mutual fund calculated?
NAV = (Assets − Liabilities) ÷ Units outstanding. Example: net assets of ₹10.4 crore ÷ 40 lakh units = NAV of ₹26.
Q: Which is better: SIP or lumpsum?
Neither is universally better. SIP suits salaried investors and volatile markets (rupee-cost averaging, low timing risk); lumpsum suits windfalls and a bullish outlook. It depends on investor profile and market view.
Q: What is a good expense ratio for exam purposes?
TER is the annual fee as a percentage of AUM. SEBI caps it on a slab basis — a maximum of about 2.25% for the first ₹500 crore AUM in equity funds; lower for debt funds and higher slabs.
Q: What are the three types of mutual funds by structure?
Open-ended (anytime purchase/redemption at NAV), close-ended (fixed maturity, no AMC redemption before maturity), and interval funds (transaction only in defined windows).
