Mutual Fund Returns Calculator India — NAV to CAGR 2026

How to Calculate Absolute Return and CAGR from NAV — and Why Growth Option Always Shows Higher NAV

A mutual fund's NAV (Net Asset Value) is the per-unit price of the fund's portfolio, calculated daily as: NAV = (Total Portfolio Value − Liabilities) / Number of Units Outstanding. For lumpsum investors, the return is calculated from the NAV at purchase to the NAV at redemption or current date.

Absolute return: (Current NAV − Purchase NAV + Dividends per unit) / Purchase NAV × 100. Example: purchased at NAV ₹100, current NAV ₹185 after 5 years, no dividends. Absolute return = (185 − 100) / 100 × 100 = 85%.

CAGR: (Current NAV / Purchase NAV)^(1/years) − 1 = (185/100)^(1/5) − 1 = (1.85)^0.2 − 1 = 1.1312 − 1 = 13.12% CAGR. This is the annualised return that a lumpsum investor earned.

Money multiplier: Current NAV / Purchase NAV = 185/100 = 1.85×. This tells you how many times your money multiplied — in this case, ₹1 lakh became ₹1.85 lakhs.

Why growth option NAV is always higher than IDCW option NAV for the same fund: In a growth option, all returns are retained in the fund and reflected in a rising NAV. In the IDCW (Income Distribution cum Capital Withdrawal) option — formerly called dividend option — periodic distributions reduce the NAV by the amount distributed. A growth option fund that started at ₹10 NAV in 2010 and distributed nothing will have a much higher NAV today than the IDCW option of the same fund that has distributed dividends multiple times. For comparing two funds' performance, always use their growth option NAVs, not IDCW, and compare over the same time period.

NAV sources: Historical NAVs for any date are available on the AMFI website (amfiindia.com → NAV History), fund house websites, and platforms like Groww, Zerodha, and CAMS. Historical NAV lookup requires the fund's scheme code or name.

Three Return Calculations That Show When a Fund Is Actually Performing

Scenario 1: Comparing two large-cap funds bought on the same date

Arjun bought Fund A (large-cap) in June 2019 at NAV ₹42. Current NAV in June 2026: ₹98. He also bought Fund B (large-cap) in June 2019 at NAV ₹65. Current NAV in June 2026: ₹131. Which performed better?

Fund A: Absolute return = (98−42)/42 × 100 = 133.3%. CAGR = (98/42)^(1/7) − 1 = (2.333)^0.1429 − 1 = 1.1266 − 1 = 12.66%.

Fund B: Absolute return = (131−65)/65 × 100 = 101.5%. CAGR = (131/65)^(1/7) − 1 = (2.015)^0.1429 − 1 = 1.1054 − 1 = 10.54%.

Fund A outperformed by 2.12% CAGR — a significant active management alpha over 7 years. In absolute rupee terms on ₹1L invested: Fund A → ₹2,33,333; Fund B → ₹2,01,538. Fund A added ₹31,795 more per ₹1L invested. The CAGR calculation using same-date NAVs is the correct method for comparing two funds.

Scenario 2: Using the Nifty 50 TRI as a benchmark

Seetha has been holding a large-cap fund for 7 years. Purchase NAV: ₹80. Current NAV: ₹175. CAGR: (175/80)^(1/7) − 1 = (2.1875)^0.1429 − 1 = 1.1185 − 1 = 11.85%.

She checks the Nifty 50 TRI (Total Return Index, which includes dividends) for the same 7-year period. Nifty 50 TRI CAGR for the same period: approximately 13.2% (verify exact figure at NSE India or AMFI for the specific dates). Her fund returned 11.85% vs the benchmark's 13.2% — underperformance of 1.35% annually. On a ₹10L investment over 7 years, this underperformance cost approximately ₹1.3L in foregone corpus. Conclusion: switch to a Nifty 50 index fund (TER: 0.05–0.1% direct plan) and capture the benchmark return at near-zero cost.

Scenario 3: Growth option vs IDCW option — why the NAV comparison misleads

Vikram has two NAV printouts: his fund's growth option at NAV ₹245 and IDCW option at NAV ₹85. He thinks his growth option investment has been more profitable. But both options are for the same underlying fund that started at ₹10 NAV in 2005. The IDCW option has distributed ₹180 per unit in dividends over 20 years, reducing the NAV proportionally each time. If Vikram had received all ₹180 in dividends and reinvested them (plus the remaining ₹85 NAV), his total return would be approximately equivalent to the growth option's ₹245 NAV — adjusted for the tax on each dividend received. The growth option is tax-efficient because no tax is triggered until redemption; IDCW triggers tax as income on each distribution. For wealth creation, growth option is almost always superior to IDCW for retail investors.

Fund Return Rules — AMFI Disclosure Standards, LTCG on Redemption, XIRR vs CAGR

SEBI and AMFI NAV disclosure requirements: SEBI (Mutual Funds) Regulations, 1996 require fund houses to calculate and publish NAV daily by 9 PM for equity funds and by 11 PM for debt funds. NAVs are submitted to AMFI, which publishes them centrally. Historical NAVs for any date back to the fund's inception are available at amfiindia.com. This transparency allows investors to compute precise returns for any holding period.

SEBI fund categories (October 2017 circular): SEBI categorised all mutual funds into distinct categories (large-cap, mid-cap, small-cap, flexi-cap, ELSS, etc.), each with mandatory portfolio composition rules. This standardisation means CAGR comparisons within a category are meaningful — all large-cap funds must hold 80% in large-cap stocks, so their CAGR differences reflect genuine fund manager alpha, not just different risk-taking.

LTCG on redemption — Section 112A (Finance Act 2024): Gains on equity mutual fund units held over 12 months: LTCG at 12.5% above ₹1.25L per FY. STCG (Section 111A): 20% if held under 12 months. For IDCW distributions: SEBI reclassified dividends as 'Income Distribution cum Capital Withdrawal' (IDCW) in 2021. IDCW payouts are taxed as income at your slab rate in the year received — they are not capital gains. Budget 2026 made no changes to LTCG or STCG rates for equity mutual funds.

CAGR applies only to lumpsum investments; XIRR for SIP: NAV-based CAGR is the correct return metric for a single purchase on one date. For SIP portfolios — with multiple purchases at different NAVs on different dates — the correct metric is XIRR (Extended Internal Rate of Return). Your fund app's portfolio view typically shows XIRR for the SIP portion and CAGR for any lumpsum holdings. SEBI's 2025 proposal to mandate XIRR disclosure for SIP investors would make this more transparent — check SEBI circulars for current status.

Consolidated Account Statement (CAS): CAMS and KFintech (the two mutual fund RTAs covering 95%+ of AUM) issue a Consolidated Account Statement once a month to investors who have transacted in that month. CAS is available on demand at camsonline.com or kfintech.com using your PAN. CAS provides transaction history with NAV at each purchase date — the data needed to compute precise XIRR for any SIP portfolio.

What Investors Get Wrong When Calculating Mutual Fund Returns

Comparing CAGR from the fund fact sheet to their actual SIP returns. A fund's 5-year CAGR on the fact sheet represents a hypothetical lumpsum investor who put money in exactly 5 years ago. If you have been doing monthly SIP for 5 years, your actual return (XIRR) could be higher or lower than the fact sheet CAGR — depending entirely on which NAVs your instalments were allotted at. During a bull market with SIP at the bottom, your XIRR may be much higher than the fund's 5-year CAGR. During a correction after a long bull run, it may be lower.

Using IDCW option NAV to evaluate growth option performance. Never compare NAVs of the growth and IDCW options of the same fund — they are meaningless without adding back all distributed dividends. If you received ₹200 per unit in IDCW distributions from a fund whose IDCW NAV is now ₹50, your actual return per unit is measured on ₹250 (₹50 current NAV + ₹200 received), not ₹50. Always compare total return (NAV appreciation + distributions) when evaluating IDCW options.

Not including dividends received in CAGR calculation. For IDCW option holders, the total return = (Current NAV − Purchase NAV + All dividends received per unit) / Purchase NAV. Omitting dividends understates the actual return. For growth option investors, NAV appreciation alone is the total return — no dividends to track.

Selecting a favourable start date to show high returns. Fund marketing materials sometimes show returns from a market bottom to a market peak — producing spectacular CAGR numbers. An investor who started at a different date would have earned very different returns. SEBI mandates standardised start dates for fact sheet CAGR, but in informal comparisons, always use the actual purchase date from your own fund statement, not industry-reported CAGR figures.
