SWP — turning a corpus into a monthly income without draining it
A systematic withdrawal plan is an SIP in reverse, with one crucial asymmetry: falling markets now work against you instead of for you.
An SIP buys units with money. An SWP sells units for money. The mechanics mirror each other, but the effect of volatility does not — and that asymmetry is the whole subject.
Why reverse averaging hurts
During an SIP, a falling market is good: the same instalment buys more units.
During an SWP, a falling market is bad: the same withdrawal sells more units. You are liquidating a larger share of the portfolio at every low, and those units are not there to recover when the market does.
This is sequence of returns risk in its most concrete form. Two portfolios with identical average returns can end decades apart depending purely on whether the bad years came early or late.
What the withdrawal rate does
₹1 crore, 9% average return, withdrawing monthly:
| Monthly withdrawal | Annual rate | Corpus after 20 years |
|---|---|---|
| ₹40,000 | 4.8% | Grown substantially |
| ₹60,000 | 7.2% | Roughly depleted |
| ₹80,000 | 9.6% | Exhausted in about 14 years |
And this assumes the withdrawal never rises. In reality it must, because inflation does.
The tax advantage over a deposit
This is where an SWP genuinely beats interest income. Every withdrawal is treated as a redemption, and only the gain portion of that redemption is taxable — not the whole amount.
Withdraw ₹50,000 from a fund where the gain component is 20%, and only ₹10,000 is a capital gain. Compare that to ₹50,000 of deposit interest, fully taxable at slab rate. For someone in a high bracket, the difference in post-tax income is substantial for the same pre-tax return.
The bucket structure
The standard mitigation for sequence risk:
- Bucket 1 — two to three years of withdrawals in liquid funds and short-duration debt. This is what you actually draw from.
- Bucket 2 — five to seven years of needs in medium-duration debt or hybrid funds.
- Bucket 3 — everything else in equity, untouched for a decade.
Refill bucket 1 from bucket 2 annually, and bucket 2 from bucket 3 after good equity years. During a market fall you simply do not refill, and draw down bucket 1 instead — which means you are never forced to sell equity at a low.
Model a withdrawal plan
Three practical rules
- Start below 5%. You can always increase later; recovering from over-withdrawal early is much harder.
- Build in an increase. A withdrawal fixed in rupees loses half its purchasing power in twelve years at 6% inflation.
- Review annually against the actual balance, not against the original plan. If the corpus is well below projection after three years, reduce the withdrawal before the arithmetic forces you to.
