What is an SWP?
What is it?
An SWP (Systematic Withdrawal Plan) is the reverse of a SIP: a fixed amount is automatically redeemed from your mutual fund and paid into your bank account at regular intervals. It's commonly used to turn an accumulated corpus into a steady income stream, such as during retirement.
Why should you care?
Once you've built a large corpus, withdrawing it all at once — or redeeming ad hoc whenever you need cash — makes it hard to plan and can trigger a larger tax bill in a single year. An SWP automates a fixed, predictable payout, and because each withdrawal only redeems the units needed to cover that amount, the rest of your corpus stays invested and keeps growing.
Real-life example
You retire with a ₹40,00,000 corpus in a mutual fund and set up an SWP of ₹20,000/month. Each month, the fund redeems however many units are needed to make up ₹20,000 at that month's NAV — more units in a month the NAV is low, fewer when it's high. The remaining corpus continues to be invested and can still grow, partially offsetting the withdrawals, as long as the fund's growth rate stays above your withdrawal rate.
Common mistakes
- Setting a withdrawal rate higher than the fund's realistic long-term growth rate, which erodes the corpus faster than it can be replenished — eventually running the corpus down to zero earlier than planned.
- Assuming SWP payouts are fixed and guaranteed like an annuity — they aren't; the corpus is still market-linked, and a prolonged downturn combined with continued withdrawals can shrink it faster than expected.
- Forgetting that each SWP withdrawal is a redemption and can trigger capital gains tax, unlike a bank fixed deposit interest payout.
How a ₹20,000/month SWP draws down a corpus depending on withdrawal rate vs. growth rate
| Scenario | Annual withdrawal | Fund's long-term growth | Corpus trend |
|---|---|---|---|
| Sustainable | 6% of corpus/year | 8-10% expected | Corpus can grow even while paying out |
| Unsustainable | 12% of corpus/year | 8-10% expected | Corpus depletes faster than it can grow |
FAQ
Is SWP just an automated way to redeem money regularly?
Yes, essentially — you set a fixed amount and frequency, and the fund automatically redeems the units needed to pay that amount into your bank account each time, rather than you manually placing a redemption request every month.
Will my corpus run out if I use SWP?
It can, if your withdrawal rate consistently exceeds the fund's growth rate over time. A withdrawal rate that stays comfortably below the fund's expected long-term return gives the remaining corpus room to keep growing even as you draw from it.
Is SWP better than a bank fixed deposit for generating income?
It depends on your risk appetite. A fixed deposit gives a guaranteed, fixed interest rate with capital protection. An SWP from a market-linked fund is not guaranteed — the corpus can fall in a downturn — but if the underlying fund's long-term returns exceed FD rates, it can be more tax-efficient and sustain a higher payout over time.
Can I change my SWP amount later?
Yes. Most platforms let you modify, pause, or stop an SWP at any time, similar to how you can adjust a SIP, though you should recheck the sustainability of the new withdrawal rate against your corpus each time you change it.
