SWP Calculator

What is a Systematic Withdrawal Plan (SWP)?

A Systematic Withdrawal Plan lets you withdraw a fixed amount from your mutual fund investment at regular intervals, typically monthly. Unlike the dividend (IDCW) option, where payouts depend on the fund’s distributable surplus, an SWP redeems specific units of your holding each period, so the amount and timing are entirely under your control.

SWPs are widely used by retirees in India to build a pension-like income stream from their corpus. The remaining invested amount keeps earning returns, which can extend the life of your corpus by decades over a flat withdrawal. If the withdrawal rate consistently exceeds the return rate, though, the corpus will eventually run out, which is exactly what this calculator is built to show you in advance.

How SWP is calculated

Each month, the calculator deducts your withdrawal amount from the opening balance, then applies your assumed annual return, divided by 12, to whatever remains. This repeats every month until the corpus is exhausted or the selected time period ends.

A month-by-month run on a Rs 50,000 corpus with a Rs 1,000 monthly withdrawal at 12% annual return looks like this:

Over a full year, the return earned only partly offsets the withdrawals, so the balance drifts down. Whether it eventually reaches zero, and when, depends entirely on how your withdrawal rate compares with your return rate, which is what the sections below cover.

What is a safe SWP withdrawal rate in India?

A safe withdrawal rate is the annual withdrawal, as a percentage of your initial corpus, that your investment returns can sustain without shrinking the principal. In India, 4 to 6% a year is the commonly used range for a 25 to 30 year retirement, though the exact figure depends on your actual returns.

The table below shows the monthly withdrawal a Rs 1 crore corpus can sustain forever at different return rates, calculated as annual return divided by 12:

Withdrawing above the sustainable figure for your assumed return rate draws down the principal itself, not just the returns on it. A corpus of Rs 50 lakh withdrawing Rs 60,000 a month at a 10% return, for instance, is above the sustainable rate and depletes entirely in about 12 years, even though the corpus keeps earning a return the whole time.

What is a step-up SWP and how do I model inflation?

A step-up SWP increases your monthly withdrawal by a fixed percentage every year instead of keeping it flat, so your income keeps pace with rising living costs. Setting the step-up rate equal to your expected inflation rate is the standard way to model an inflation-adjusted SWP, since it keeps your withdrawal at roughly constant real purchasing power each year.

Turn this on from the More Settings panel above. A withdrawal starting at Rs 30,000 a month with a 6% annual step-up grows like this:

A step-up SWP depletes a fixed corpus faster than a flat SWP at the same starting withdrawal, since the withdrawal grows every year while the corpus does not get any larger. On a Rs 1 crore corpus at 10% return, a flat Rs 50,000 monthly withdrawal never runs out, but the same withdrawal stepped up 6% a year depletes the corpus by year 30. Model both scenarios with this calculator before committing to a step-up rate.

Should you combine SIP and SWP?

Yes, running an SIP during your working years and switching to an SWP after retirement is the standard two-phase approach used by most Indian investors, and the two calculators are meant to be used together, one for each phase.

You accumulate a corpus through SIP for 20 to 30 years, then switch that same fund, or move to a lower-volatility fund, into SWP mode once you stop earning a salary. Some investors run both at once in the years just before retirement: a smaller SIP continues in one fund while SWP begins in another, as a gradual transition rather than a single switch on the retirement date.

SWP vs lumpsum withdrawal: which is better?

SWP is better than a lumpsum withdrawal for anyone who needs regular income rather than a one-time sum, because it spreads out both the tax impact and the loss of compounding. A lumpsum withdrawal redeems your entire investment at once, which triggers capital gains tax on the full gain in a single financial year and stops any further compounding on that money immediately. An SWP redeems only what you need each period, so tax is spread across withdrawals and years, and the untouched portion of the corpus keeps compounding.

A lumpsum withdrawal makes sense mainly when the entire amount is needed immediately, for example to fund a large one-time expense. Outside that case, SWP is almost always the more tax-efficient and financially sound choice.

SWP vs the dividend (IDCW) option

In an SWP, you redeem a fixed number of units each period to receive a predictable, self-decided payout, and the transaction is treated as a capital gain for tax purposes. In the dividend option, now called Income Distribution cum Capital Withdrawal per SEBI nomenclature, the fund house distributes returns from realised profits at its own discretion, so the amount and timing are not guaranteed.

SWP gives investors more predictability and generally better tax efficiency, which is why it has become the default choice for retirement income planning over the dividend option.

How is SWP taxed?

Every SWP withdrawal is treated as a partial redemption of units and taxed on the gain portion, not the full withdrawal amount. For equity mutual funds, units held over 12 months are taxed at 12.5% as long-term capital gains, with the first Rs 1.25 lakh of gains in a financial year exempt. Units held under 12 months are taxed at 20% as short-term gains.

For debt mutual funds, all gains from an SWP are added to your income and taxed at your applicable slab rate, per the Finance Act 2023 amendment that removed indexation benefits on debt funds.
