Growth vs IDCW: which option should you pick?
How the two payout options affect your fund's NAV and your actual returns.
Every mutual fund offers a choice between two payout options on the same underlying portfolio: Growth, where nothing is ever paid out and the NAV simply compounds, and IDCW(Income Distribution cum Capital Withdrawal, the option formerly called “Dividend”), which periodically pays out cash and drops the NAV by exactly that amount. The two aren’t different investments — they’re the same fund, sliced differently.
The NAV drop isn’t a loss
The most common source of confusion: an IDCW payout makes the fund’s NAV visibly drop overnight, which can look like the investment just lost value. It didn’t — the drop is exactly equal to the cash paid out per unit. Your total wealth at that instant — units × (new, lower) NAV, plus the cash you just received — is unchanged. An IDCW payout is your own money coming out of the fund, not new money being created.
The same fund, two very different outcomes
₹1,00,000 in a fund with a true 12% annual total return, held 5 years. Growth (nothing distributed, everything compounds): ₹1,76,234.17. The identical fund under IDCW, with every payout immediately reinvested (distributing 4% of NAV a year, then buying more units with it): also exactly ₹1,76,234.17— the two options are mathematically identical once every rupee paid out goes straight back in. IDCW with the payouts left as idle cash instead: only ₹1,69,728.50— 3.7% less, purely from the compounding those distributed rupees missed out on by sitting idle instead of staying invested.

That 3.7% gap is the entire practical difference between the two options in a frictionless world: Growth reinvests every rupee automatically, by construction; IDCW only matches it if you manually reinvest every single payout, and any payout you don’t is a small, permanent dent in the compounding you’d otherwise have gotten.
So which should you pick
For pure wealth accumulation with no need for periodic cash, Growth is the simpler default — it reinvests automatically and defers all tax to the point of redemption, rather than triggering a taxable event at every distribution the way IDCW does regardless of whether you reinvest it. IDCW is worth considering specifically when the goal is a regular cash income stream from the investment itself — though even then, an SWP from a Growth-option fund usually gives more control, since you choose the exact amount and timing withdrawn rather than accepting whatever the fund decides to distribute and when.
