A Systematic Withdrawal Plan is the mirror image of a SIP. Instead of putting a fixed amount in each month, you instruct the fund house to take a fixed amount out and credit it to your bank account, while the rest of your units stay invested and continue to grow or fall with the market.
It is the standard way Indian retirees convert a lump sum corpus into a monthly income without liquidating everything at once.
How the mechanics work
You hold units. Each month, on your chosen date, the fund redeems just enough units to pay you the amount you specified, at that day's NAV.
Say you hold Rs 50 lakh and want Rs 25,000 a month. If the NAV is Rs 100, the fund sells 250 units. If the NAV has risen to Rs 110 the next month, it sells about 227 units. If it has fallen to Rs 90, it sells about 278.
That last case is the important one. When markets fall, an SWP sells more units for the same rupees. This is rupee cost averaging running in reverse, and it works against you rather than for you.
Will the corpus last?
The arithmetic is simply growth against withdrawal rate.
On a Rs 50 lakh corpus with an assumed 10% annual return:
| Monthly withdrawal | Annual withdrawal rate | Rough outcome |
|---|---|---|
| Rs 25,000 | 6% | Corpus grows slowly over time |
| Rs 35,000 | 8.4% | Roughly stable, sensitive to bad years |
| Rs 50,000 | 12% | Depletes within about 15 years |
| Rs 70,000 | 16.8% | Depletes within about 8 years |
The widely-cited guideline is to keep withdrawals in the region of 4% to 6% of the corpus a year if you want it to last indefinitely, and to review it as inflation raises your expenses.
Sequence of returns risk
This is the genuine danger in an SWP, and it is not obvious.
Two retirees both average 10% a year over twenty years. One has good years first and bad years later; the other has the bad years first. The average is identical, the outcome is not. The one who hit a market crash in the first three years of withdrawals sold a large number of units at depressed prices, permanently removing them from the recovery, and may run out of money years earlier.
The practical defences are to keep two to three years of planned withdrawals in a liquid or short-duration debt fund so you are not forced to sell equity during a fall, to hold the equity portion for the later years of the plan, and to be willing to reduce withdrawals temporarily in a bad year.
Why an SWP beats IDCW on tax
This is the main technical reason advisers prefer SWPs.
An IDCW or dividend payout is taxed in full at your slab rate. Receive Rs 25,000 and, in a 30% bracket, roughly Rs 7,500 goes to tax.
An SWP withdrawal is a redemption, so only the gain portion of each withdrawal is taxable, and it is taxed at capital gains rates. If Rs 25,000 of units includes Rs 5,000 of gain, only that Rs 5,000 is assessed, and for equity units held over a year it falls under the long-term rate with an annual exemption threshold applied first.
The rest is your own capital coming back, which was never income. For a retiree drawing from a large corpus, the difference over a decade is substantial. Rates and exemptions change with Budget announcements, so confirm the current figures.
Practical points before you start one
- Check the exit load. Withdrawals within the load period, often one year, attract a charge on top of tax. Many people start an SWP only after that window closes.
- Growth option only. Running an SWP on an IDCW plan combines the worst of both.
- Debt funds for short horizons. If the corpus must last only three or four years, an equity SWP exposes you to exactly the volatility you cannot afford.
- You can change or stop it any time. Unlike an annuity, an SWP is fully reversible and the corpus remains yours and inheritable, which is one of its main advantages over the annuity leg of NPS.
