What Is an SWP? How a Systematic Withdrawal Plan Works
A systematic withdrawal plan (SWP) lets you take a fixed amount out of a mutual fund every month while the rest stays invested. It works well when you withdraw less than the fund earns, and it can drain your corpus faster than you expect when you withdraw more. The number that decides everything is your withdrawal rate: the share of the corpus you take out each year.
How an SWP works
You invest a lump sum in a mutual fund, then instruct the fund house to redeem a fixed number of rupees' worth of units on a set date each month. The money arrives in your bank account, and the units that remain stay invested and keep rising or falling with the market. It is the mirror image of a SIP: a SIP buys units every month, an SWP sells them.
The appeal is control. You choose the amount and the date, and unlike FD interest you are not forced to take a fixed payout — you can pause, raise or stop the plan.
The number that matters: your withdrawal rate
Suppose you invest ₹50 lakh and withdraw ₹30,000 a month. That is ₹3.6 lakh a year, or a 7.2% withdrawal rate. If the fund averages 10% a year, the corpus earns about ₹41,667 a month, which is more than you take out. After 20 years you would have withdrawn ₹72,00,000 and still hold about ₹1,38,59,303.
Now change two assumptions: withdraw ₹50,000 a month (a 12% rate) and let the fund average 8%. The same ₹50 lakh runs out in 13 years and 10 months, after paying out ₹82,67,064. Nothing dramatic changed, yet one plan outlives you and the other does not. That is why a small shift in either number deserves attention.
Why a smooth average can mislead you
Calculators assume the same return every year. Real markets do not behave that way, and with an SWP the order of returns matters. If the market falls early, you are forced to sell units cheaply to fund your withdrawals, and there are fewer units left to benefit from the recovery. The same bad years later in the plan do much less damage. This is called sequence risk, and it is the main reason to keep the withdrawal rate modest.
How an SWP is taxed
Each withdrawal is a sale of units, so only the gain portion of each payout is taxed, as capital gains, while the part that is your original capital is not. The rate depends on the type of fund and how long you held the units, and tax rules change, so check the current position with a tax professional. Compared with FD interest, which is taxed in full at your slab every year, an SWP can be tax-efficient, but it carries market risk that an FD does not.
Practical rules that keep an SWP safe
- Start conservative. A first-year withdrawal rate around 4% of the corpus is a common planning starting point; it comes from research on other markets, so treat it as a reference and not a guarantee in India.
- Keep a cushion. Holding one to two years of withdrawals in a low-risk fund means you are not selling equity units during a crash.
- Raise the amount slowly. If you step the withdrawal up each year for inflation, model it. Withdrawals that rise faster than the corpus grows eventually catch up.
- Review once a year. If the balance is shrinking faster than planned, cut the withdrawal early rather than late.
