Every mutual fund scheme in India offers at least two options at the time of investing: Growth and IDCW (Income Distribution cum Capital Withdrawal — the renamed 'Dividend' option). The name change happened in 2021 because SEBI wanted investors to stop thinking of it as free income. It isn't. Let's unpack why.
In the growth option, the fund does not pay out anything. Any profits the fund makes — interest, dividends from underlying stocks, capital appreciation — stay inside the scheme and get reflected in a rising NAV (Net Asset Value). You only realise your gain when you redeem units, and it's taxed as capital gains at that point.
This is the default, and sensible, choice for most long-term investors — especially in SIPs building toward retirement, a house, or children's education.
In the IDCW option, the fund periodically pays out a sum per unit to investors — this could be monthly, quarterly, or whenever the fund house declares it. But here's the part most people miss: the NAV drops by the exact amount paid out. If NAV was ₹50 and the fund declares an IDCW of ₹2 per unit, the NAV falls to ₹48 immediately after. You haven't gained anything extra — you've simply been handed a slice of your own capital back in cash.
| Growth | IDCW | |
|---|---|---|
| Payout | None — reinvested | Periodic, NAV-linked |
| NAV behaviour | Rises with fund performance | Drops after each payout |
| Compounding | Uninterrupted | Reduced — capital taken out can't grow |
| Taxation | Capital gains, only on redemption | Added to income, taxed at slab rate when paid |
| Best suited for | Long-term wealth building | Investors needing periodic cash flow |
Two investors put ₹5 lakh each into the same fund — one in growth, one in IDCW. Over 10 years, if the underlying fund performs identically, the growth investor's corpus compounds fully. The IDCW investor receives periodic payouts, each of which:
The IDCW investor's final corpus is typically noticeably lower — not because the fund performed worse, but because compounding was repeatedly interrupted and tax was paid earlier than necessary.
Even then, many advisors suggest a Systematic Withdrawal Plan (SWP) from a growth-option fund instead — you control the withdrawal amount and timing, rather than leaving it to the fund house's IDCW declaration schedule. It's usually more tax-efficient too, since SWP withdrawals are treated as partial redemptions (a mix of capital and gain) rather than fully taxed at slab rate.
Unless you have a specific, ongoing need for cash flow and understand exactly how NAV reduction works, choose growth. It's simpler, more tax-efficient for long holding periods, and lets compounding do its job without interruption. If you need periodic income, look at an SWP from a growth-option fund before defaulting to IDCW — it usually achieves the same goal more efficiently.
