SWP — generating regular income from a corpus

The reverse of a SIP: a Systematic Withdrawal Plan (SWP) automatically redeems a fixed amount from your mutual fund holding every month (or quarter) and credits it to your bank account. It's the most tax-efficient way to draw a regular income from an accumulated portfolio.

Why SWP beats IDCW for income

The intuitive alternative — dividends (IDCW) — has worse tax economics for most investors:

• IDCW is taxed at slab rate (added to your total income).
• SWP is a redemption — capital-gains tax only on the gain portion of each withdrawal, not the whole amount.

For a long-held equity fund, the gain portion of each ₹1 redeemed might be ₹0.30-0.50, taxed at 12.5%. For IDCW, the full ₹1 is taxed at your slab rate (potentially 30%+).

The 4% rule (and its caveats)

A classic retirement-research result: withdrawing 4% of the starting corpus annually (adjusted for inflation each year) has historically lasted 30 years across most US market scenarios. In Indian markets the equivalent number is harder to pin down precisely, but 4-6% is the workable range for a 25-30 year retirement.

The rate is sensitive to:

• Asset allocation — 100% equity is more fragile to early drawdowns than 60/40.
• Inflation — a long high-inflation stretch can break the math.
• Sequence of returns — a market crash in year 1-3 of retirement hurts more than the same crash in year 20.

Setting one up

Specify: source fund, withdrawal amount, frequency (monthly is most common), start date, end date or "until balance exhausted". Most AMCs and platforms offer this at no extra charge.

Pre-retirement uses

SWP isn't only for retirement. Useful for:

• Drawing kid's college fees over 4 years.
• Supplementing irregular income during a career break.
• Converting a windfall into a structured monthly cashflow.
