Mutual Fund Returns Calculator — NAV-Based Return with Expense Ratio

Mutual Fund Returns Calculator — NAV, Units, and Expense Ratio Impact

How mutual fund returns are calculated

Mutual fund returns are entirely NAV-driven. When you invest, units are allotted at the prevailing NAV. When you redeem, the AMC pays you based on the applicable NAV on the redemption date. The return is simply:

Invested amount = Units bought × Purchase NAV

Redemption value = Units bought × Redemption NAV

Absolute return % = (Redemption Value − Invested Amount) / Invested Amount × 100

CAGR = (Redemption NAV / Purchase NAV)^(1 / Holding Years) − 1

CAGR is the SEBI standard metric for point-to-point return disclosure on mutual fund factsheets. This calculator uses the same formula.

The expense ratio — the invisible drag

The TER (Total Expense Ratio) is deducted from the fund’s NAV daily before it is published. You never see it as a separate charge, but it reduces your effective return every single day.

A direct plan of the same fund will always have a lower TER than the corresponding regular plan because there is no distributor commission. Over a 20-year horizon, a 1% per year TER difference compounds to a meaningful gap:

Scenario	Invested	20yr @ 12%	20yr @ 11%	Difference
Direct plan (TER 0.5%)	₹10,00,000	₹96.5L	—	—
Regular plan (TER 1.5%)	₹10,00,000	—	₹80.6L	₹15.9L

This calculator’s expense drag field lets you compare two TER scenarios side-by-side.

Growth vs IDCW (dividend) options

Growth option: profits are retained and reinvested into the NAV. Your NAV rises over time. No tax event until you redeem.

IDCW option (formerly dividend): the fund periodically distributes a portion of gains. The NAV falls by the distribution amount. The distribution is taxable as per your income slab in the year of receipt.

For long-term compounding, the growth option is structurally superior. Use IDCW only if you need periodic cash flow from the investment.

Worked examples

Example 1 — Mid-cap fund, 5-year hold

500 units bought at NAV ₹40; redeemed at NAV ₹60 after 5 years
Invested: ₹20,000; Redemption value: ₹30,000
Absolute return: ₹10,000 (50%)
CAGR: (60/40)^(1/5) − 1 ≈ 8.45%
With 1% TER, expense drag over 5 years ≈ ₹1,000 (approximate)

Example 2 — Short-term, 1-year hold (STCG territory)

100 units at NAV ₹25; redeemed at NAV ₹32 after 1 year
Invested: ₹2,500; Redemption value: ₹3,200
Absolute return: ₹700 (28%)
CAGR: (32/25)^1 − 1 = 28% (same as absolute return for 1-year hold)
Tax note: held < 1 year, so STCG at 20% applies. Tax ≈ ₹140. Net: ₹560.

Example 3 — Direct vs regular plan comparison

200 units at NAV ₹50; redeemed at NAV ₹100 after 5 years
CAGR ≈ 14.87% (2× growth in 5 years)
With direct plan TER 0.5%: expense drag ≈ ₹500
With regular plan TER 1.5%: expense drag ≈ ₹1,500
Difference over the 5-year hold: ₹1,000 — and this grows as corpus scales

Tax on mutual fund redemption gains

Once you have the gain figure from this calculator, the applicable tax depends on the fund category and holding period. For equity mutual funds (≥ 65% equity allocation), gains on units held more than 1 year are LTCG taxed at 12.5% on amounts above ₹1.25L per year (Budget 2024); use our LTCG equity tax calculator to compute the exact liability. For debt mutual funds purchased on or after 1 April 2023, the Finance Act 2023 removed the indexation benefit — all gains are added to your income and taxed at your slab rate regardless of holding period. Use our debt MF capital gains calculator to calculate the after-tax return on debt fund redemptions.

Mutual fund investments are subject to market risk

Mutual fund investments are subject to market risk. Past NAV performance does not guarantee future returns. This calculator uses your input NAVs to compute historical or hypothetical returns — it does not predict future NAV movement. Read all scheme-related documents carefully before investing.

Frequently Asked Questions

What is NAV and how is it different from a stock price?

NAV (Net Asset Value) is the per-unit value of a mutual fund, calculated daily as: (Total assets of the fund − Liabilities) / Number of outstanding units. Unlike a stock price, which fluctuates in real time on an exchange, NAV is struck once per day after market close for open-ended mutual funds. When you invest ₹10,000 in a fund at a NAV of ₹50, you receive 200 units. When you redeem at NAV ₹80, you get ₹16,000 — a gain of ₹6,000 or 60% absolute return.

Why does the expense ratio matter so much?

The expense ratio (TER — Total Expense Ratio) is the annual cost charged by the AMC to manage the fund, expressed as a percentage of AUM. It is deducted from the fund's NAV daily before publication, so you never see it as a line-item charge. Over long periods, even a 1% difference compounds significantly: ₹10L invested for 20 years at 12% CAGR grows to ₹96.5L, but at 11% CAGR (after 1% expense) it grows to only ₹80.6L — a ₹15.9L difference. SEBI has set TER caps: equity funds are capped at ~1.05–2.25% (depending on AUM) for regular plans.

What is the difference between a regular plan and a direct plan?

A regular plan is bought through a distributor (broker, bank, financial advisor). The AMC pays the distributor a commission from the TER — so regular plan TERs are higher by 0.5–1.5 percentage points. A direct plan is bought directly from the AMC or through direct portals (MF Utilities, AMC websites). Direct plans have no distributor commission, so their TER is lower and their NAV is higher for the same portfolio. Over 20 years, direct plans can meaningfully outperform regular plans of the same fund due to the compounding of the lower TER.

What is the ELSS lock-in period and how does it affect returns?

ELSS (Equity Linked Savings Scheme) funds have a mandatory 3-year lock-in per investment, making each SIP instalment individually subject to a 3-year lock from its allotment date. You cannot redeem within 3 years — not even if the NAV doubles. The ELSS lock-in exists because these funds qualify for Section 80C deduction (up to ₹1.5L per year). The lock-in is per unit allotment, so in a monthly SIP, each month's units are released 3 years after that specific month's investment. Gains after 3 years are treated as LTCG for equity funds: taxable at 12.5% above ₹1.25L.

What is the difference between dividend and growth options in mutual funds?

In a growth option, all profits are reinvested into the fund NAV. NAV grows over time and you realise returns only when you redeem. In a dividend option (now called IDCW — Income Distribution cum Capital Withdrawal), the fund periodically distributes part of its gains as dividends, reducing the NAV by the dividend amount. The dividend is taxable as per your income slab. For long-term wealth creation, the growth option is generally preferred because reinvested returns compound more efficiently. IDCW is better suited to investors who need periodic cash flow from their investment.

How are mutual fund returns taxed in India?

Taxation depends on the fund category and holding period. For equity mutual funds (≥65% equity): STCG (held < 1 year) is taxed at 20%; LTCG (held ≥ 1 year) is taxed at 12.5% on gains above ₹1.25L per year (Budget 2024 rate). For debt mutual funds (purchased on or after 1 April 2023): gains are added to income and taxed at your slab rate regardless of holding period. For hybrid and other categories, the equity/debt classification of the underlying portfolio determines the applicable rate. This calculator does not compute the tax — use our [LTCG equity tax calculator](/tax/capital-gains-calculator/ltcg-equity-calculator/) for that step.

What is the difference between absolute return and CAGR for mutual funds?

Absolute return is the total percentage gain irrespective of time: (Redemption Value − Invested Amount) / Invested Amount × 100. A 100% absolute return tells you the NAV doubled, but not how long it took. CAGR (Compound Annual Growth Rate) normalises for time: CAGR = (Redemption NAV / Purchase NAV)^(1/years) − 1. A 100% gain in 5 years is a CAGR of ~14.87%; the same gain in 10 years is a CAGR of ~7.18%. CAGR is the right metric for comparing funds held over different periods or against benchmarks and FD rates.
