Retirement income
Turning a corpus into a monthly income
An SWP is the mirror image of a SIP. Instead of putting a fixed amount in every month, you take a fixed amount out. The arithmetic of doing that safely is less obvious than it looks.
Most investment conversation is about accumulation — how to build a corpus. Far less attention is paid to the harder half: how to spend it without running out. An SWP is the tool for that, and understanding what it does to your capital is more important than understanding how to set it up.
The mechanics
You hold units in a scheme. You instruct the fund house to redeem, say, ₹40,000 worth of units on the 5th of every month and credit the proceeds to your bank. The number of units sold depends on that day’s NAV, so it varies. The rest of your holding continues to be invested.
That last point is what distinguishes an SWP from simply keeping money in a bank account and spending it. The unwithdrawn portion is still working. In a good decade it can grow faster than you are withdrawing, and the corpus ends larger than it started — while having paid you an income throughout.
Why the withdrawal rate decides everything
Take a corpus of ₹1 crore and an assumed 10% annual return, and vary only the monthly withdrawal.
| Monthly withdrawal | Annual rate | Corpus after 20 years |
|---|---|---|
| ₹40,000 | 4.8% | ₹3.35 crore |
| ₹60,000 | 7.2% | ₹1.72 crore |
| ₹80,000 | 9.6% | ₹9 lakh |
| ₹1,00,000 | 12.0% | Exhausted in year 15 |
The return assumption is identical in all four rows. Only the withdrawal changes, and it changes the outcome from a corpus that has tripled to one that has disappeared. This is the single most important idea in retirement planning, and it is why we spend more time on the withdrawal figure than on scheme selection.
Sequence risk, in one sentence
Two retirees can experience the same average return over twenty years and end with wildly different results, purely because one met a bad market in year two and the other met it in year eighteen. The early one had to sell more units at low prices, and never recovered them. This is why the first few years of a withdrawal plan deserve a conservative rate and a cash cushion.
Accumulation and withdrawal are one plan
It is common to plan a SIP for retirement without ever asking what income the resulting corpus can actually produce. The two halves need to be designed together. If you need ₹60,000 a month in today’s money in twenty years, inflation will have raised that requirement substantially, and the corpus has to be sized against the inflated figure, not the current one.
The SIP to SWP calculator models both phases in sequence — what your SIP builds, and what that corpus can then pay out. It is the most useful of the nine tools for anyone within fifteen years of retiring.
SWP against a fixed deposit
A fixed deposit pays a contracted rate; the entire interest is added to your income and taxed at your slab. An SWP pays whatever you instruct; only the capital gain inside each withdrawal is taxable, and equity-oriented gains held beyond a year are taxed at a lower rate with an annual exemption.
The deposit gives certainty. The SWP gives the possibility of the corpus keeping pace with inflation, and the risk that it does not. For most retirees the sensible answer is a split: cover essential monthly expenses from certain sources, and take discretionary income from an SWP.
Setting one up
Three decisions: how much per month, from which scheme, and on what date. The amount should come from a corpus calculation rather than from what you happen to need, because those two numbers are often far apart — and finding that out in year one is much better than finding out in year twelve.
Run your figures in the SWP calculator. It shows how long the corpus lasts at the rate you enter and lets you save the projection as a PDF. Mutual fund investments are subject to market risks; the projection assumes a constant return and real markets do not provide one.
Common questions
What is an SWP?
A Systematic Withdrawal Plan is a standing instruction to redeem a fixed amount from your mutual fund holding at a fixed interval, usually monthly, and credit it to your bank account. The remaining units stay invested.
How much can I withdraw safely?
As a working rule, a withdrawal of 5 to 6% of the corpus a year is usually sustainable from an equity-oriented portfolio over long periods, though nothing is guaranteed. Above about 8% the risk of exhausting the corpus rises sharply.
Is SWP income taxed?
Each withdrawal is a redemption, so the gain portion is taxable as capital gains — short or long term depending on how long those units were held. Only the gain is taxed, not the whole withdrawal, which is why the effective tax is usually lower than on fixed deposit interest.
What happens if the market falls while my SWP runs?
You redeem more units to produce the same rupee amount, which depletes the corpus faster. This is called sequence risk, and it is the main reason a conservative withdrawal rate matters.
Can I change or stop the SWP?
Yes, at any time. The amount, date and frequency can all be changed, and the plan can be paused if you do not need the income for a period.
Is SWP better than a fixed deposit for monthly income?
It offers the possibility of the corpus growing while you withdraw, and usually a lower tax burden. It also carries market risk that a fixed deposit does not. Many retirees use both — a deposit for the certain portion of expenses, an SWP for the rest.
