A Systematic Withdrawal Plan, or SWP, is a simple idea with powerful results: instead of pulling your entire mutual fund investment out at once, you withdraw a fixed amount every month while the rest stays invested and keeps growing. If a SIP is how you build a corpus, an SWP is how you turn that corpus into a steady, predictable income.
How does an SWP work?
You choose a monthly amount — say ₹30,000 — and the fund house redeems just enough units each month to pay it to you. The units you do not redeem stay invested, so they continue to earn returns. Every month becomes a small tug-of-war: your withdrawal pulls the balance down, and the market’s return pushes it back up.
How long will the money last?
This is the question that matters most, and the answer depends entirely on the gap between your return and your withdrawal rate. If your corpus earns 10% a year and you withdraw only about 7% of it, the corpus can actually grow while paying you. Push your withdrawals well above your return, and the fund drains — sometimes surprisingly fast. Our SWP calculator shows the exact year your money would run dry for any combination you enter.
The biggest hidden risk
The danger with an SWP is not the average return — it is the order of returns. A run of poor years early in your withdrawal phase forces you to sell more units when prices are low, permanently shrinking the corpus. This is called sequence-of-returns risk, and it is why a cautious withdrawal rate and a buffer of safer assets matter so much in the early years.
SWP versus a bank fixed deposit
An FD gives you fixed, guaranteed interest but no growth, and the interest is fully taxable. An SWP carries market risk, but it can grow your remaining corpus and is often more tax-efficient, since only the gains portion of each withdrawal is taxed. Neither is strictly better — it depends on your risk appetite and need for certainty.
Making inflation part of the plan
A fixed ₹30,000 will buy less every year. To keep your real lifestyle steady, many retirees step their withdrawal up with inflation. Our inflation-adjusted SWP calculator models this and even shows your ending balance in today’s money.
The best way to understand an SWP is to try one. Open the calculator, enter your numbers, and watch the year-by-year balance react as you change the withdrawal.
