SWP Calculator – Plan Monthly Income from Mutual Fund Withdrawals
A Systematic Withdrawal Plan (SWP) turns a lump-sum mutual fund investment into a steady monthly income without redeeming the whole corpus at once. Use the calculator below to see your total withdrawals, remaining balance, and returns earned.
This page also does something most SWP calculators skip: it works out how much tax you will actually pay. For a typical SWP, the answer is close to nothing — and understanding why is the strongest argument for choosing one over a fixed deposit.
What Is a Systematic Withdrawal Plan (SWP)?
An SWP is a mutual fund facility that lets you withdraw a fixed amount at regular intervals — monthly, quarterly, or annually — from your invested corpus. Unlike a one-time redemption, the remaining units stay invested and keep earning.
Key characteristics:
- Withdrawals are processed automatically at a frequency you set
- Remaining units stay invested and participate in market growth
- Available on equity, debt, and hybrid mutual funds
- Tax applies only to the capital gains portion of each withdrawal, not the full amount
- No lock-in — you can pause, change, or stop withdrawals at any time
That fourth point is the one that does most of the work, and it is explained in detail below.
SWP is widely used for retirement income planning because it behaves like a salary while the remainder of the investment continues to compound.
How the Calculator Works
The calculator simulates your balance one period at a time:
B_n = B_{n-1} \times \left(1 + \frac{r}{12}\right) - WWhere Bn is the balance at the end of period n, r is the annual return in decimal form, and W is the fixed withdrawal.
Run forward across the full duration, this resolves to:
B_n = B_0 \times (1+i)^n - W \times \frac{(1+i)^n - 1}{i}Where i is the monthly rate (annual ÷ 12) and n the number of months.
Inputs: total investment, withdrawal amount, duration in years, expected annual return.
Outputs: total withdrawn, final balance, and returns earned on the remaining corpus.
Worked Example
Inputs:
- Investment: ₹20,00,000
- Monthly withdrawal: ₹15,000
- Duration: 15 years
- Expected return: 10% per annum
Results:
| Measure | Amount |
|---|---|
| Starting corpus | ₹20,00,000 |
| Total withdrawn over 15 years | ₹27,00,000 |
| Returns earned | ₹33,90,776 |
| Final corpus remaining | ₹26,90,776 |
You withdraw ₹27 lakh across fifteen years and still end with 34% more than you started with. The corpus does not merely survive — it grows, because a ₹15,000 monthly withdrawal is 9% per year of the starting corpus while returns run at 10%.
That margin is the whole game. When the return rate exceeds the withdrawal rate, the corpus compounds indefinitely. When it doesn’t, the corpus is on a countdown.
How Much Tax Will You Actually Pay?
This is where SWP separates itself from every other income option, and where most calculators go quiet.
Only the gain portion of each withdrawal is taxed. When you redeem ₹15,000 of units, most of that ₹15,000 is your own capital coming back — not income. Only the growth on those specific units is a capital gain.
In the early years the growth on any given unit is small, so the taxable portion of each withdrawal is small. It rises over time as units are held longer, but slowly.
Here is the actual year-by-year tax on the example above — ₹20 lakh corpus, ₹15,000 per month, 10% return, assuming this is the investor’s only capital gain:
| Year | Withdrawn | Taxable gain portion | Tax treatment | Tax payable |
|---|---|---|---|---|
| 1 | ₹1,80,000 | ₹9,452 | Short-term, 20% | ₹1,890 |
| 2 | ₹1,80,000 | ₹25,617 | Long-term, under exemption | ₹0 |
| 5 | ₹1,80,000 | ₹65,494 | Long-term, under exemption | ₹0 |
| 10 | ₹1,80,000 | ₹1,10,411 | Long-term, under exemption | ₹0 |
| 13 | ₹1,80,000 | ₹1,28,386 | Long-term, ₹3,386 above exemption | ₹423 |
| 15 | ₹1,80,000 | ₹1,37,708 | Long-term, ₹12,708 above exemption | ₹1,589 |
Total tax across all fifteen years: approximately ₹4,937 — about 0.18% of everything withdrawn.
The reason is the ₹1.25 lakh annual exemption on long-term equity gains. The gain component of a ₹1.8 lakh annual withdrawal does not cross that threshold until year thirteen.
Why year one is different
Mutual fund redemptions follow FIFO — first in, first out. Units held twelve months or less are short-term and taxed at 20%; units held longer are long-term and taxed at 12.5% above the exemption.
For a lumpsum invested on a single date, every unit crosses the twelve-month mark together. So only your first twelve months of withdrawals are short-term, and in those months the gain component is at its smallest — which is why the year-one tax is under ₹2,000 despite the higher rate.
Two ways to avoid it entirely: start the SWP twelve months after investing, or accept the small cost as the price of starting income immediately.
The comparison that matters
To draw a similar income from a fixed deposit, a ₹20 lakh FD at 7% generates about ₹1,40,000 of interest in year one. Every rupee of that is taxed at your slab rate — roughly ₹42,000 for a 30% taxpayer, and it recurs every year.
| Year one | SWP (equity fund) | Fixed deposit |
|---|---|---|
| What is taxed | Gain portion of redemptions only | Full interest earned |
| Taxable amount | ₹9,452 | ₹1,40,000 |
| Rate applied | 20% (short-term) | Slab rate — 30% assumed |
| Tax payable | ₹1,890 | ₹42,000 |
Assumes this is the investor’s only capital gain in the year and that the full ₹1.25 lakh exemption is available. Surcharge and cess excluded. TDS applies on FD interest above ₹1,00,000 for senior citizens and ₹50,000 for others, adjusted at filing.
Exit Load: Check Before You Start
Most equity mutual funds charge an exit load of about 1% on units redeemed within twelve months of purchase. An SWP started immediately after a lumpsum investment will trigger it on every withdrawal in the first year.
Many schemes allow a portion of units — often 10% of the holding per year — to be redeemed load-free. Read the scheme information document before setting the withdrawal amount, because a 1% load on early withdrawals can exceed the tax on them.
Sequence of Returns: The Risk Unique to Withdrawals
This risk does not exist while you are accumulating, and it is the single most under-discussed factor in withdrawal planning.
When you are only investing, the order in which returns arrive is irrelevant — only the compounded total matters. Once you are withdrawing, order matters enormously, because a fall early on means you are selling units at depressed prices and those units are gone.
An illustration. A ₹50 lakh corpus, ₹5 lakh withdrawn at the end of each year, over three years with returns of −20%, +10% and +30% — the same three returns, in two different orders:
| Bad year first (−20, +10, +30) | Good year first (+30, +10, −20) | |
|---|---|---|
| After year 1 | ₹35,00,000 | ₹60,00,000 |
| After year 2 | ₹33,50,000 | ₹61,00,000 |
| After year 3 | ₹38,55,000 | ₹43,80,000 |
Identical returns, identical withdrawals, a gap of ₹5.25 lakh — and it widens over longer horizons. With no withdrawals at all, both sequences end at exactly ₹57.2 lakh.
What to do about it:
- Hold two to three years of withdrawals in a liquid or short-duration debt fund, and draw from that during market falls instead of selling equity units cheaply
- Set the withdrawal rate with room to spare, so a bad opening stretch does not force a mid-plan cut
- Consider reducing the withdrawal temporarily after a sharp fall rather than holding it fixed
- Use a balanced advantage or equity savings fund rather than pure equity if the SWP is your primary income
This is also why the calculator’s single fixed return rate is optimistic by construction. Real markets do not deliver 10% every year, and the variation costs you.
Choosing a Withdrawal Rate
The withdrawal rate — the percentage of your corpus taken each year — is the most consequential input you will choose.
On the 4% rule. The global benchmark suggests withdrawing 4% of the starting corpus in year one, then increasing that rupee amount with inflation each year, as sustainable for a 30-year retirement.
It is sometimes argued that Indian investors can safely take 5–6% because Indian equity returns are higher. That reasoning does not hold, because it compares nominal returns while ignoring that Indian inflation is also higher. What governs a withdrawal rate is the real return:
| Nominal return | Inflation | Real return | |
|---|---|---|---|
| Indian equity | 12% | 6% | 5.66% |
| US equity | 10% | 3% | 6.80% |
Real return calculated as (1 + nominal) ÷ (1 + inflation) − 1.
India’s real return is lower, not higher. A rate of 4–5% with annual inflation increases is the defensible starting point, and higher rates should be a deliberate choice to spend down capital rather than an assumption that it will last.
Practical guidance:
- 3–4% with inflation increases — corpus likely grows; suitable if you want to leave an estate
- 5–6% with inflation increases — corpus roughly holds in real terms over a 25–30 year horizon, with meaningful dependence on sequence of returns
- 7%+ — planned depletion. Fine if intentional and if the horizon is short, but model when the corpus runs out
To work backwards from a target income to the corpus you need, use the Goal SIP Calculator.
Adjusting Withdrawals for Inflation
A fixed ₹15,000 per month does not stay worth ₹15,000. At 6% inflation it has the purchasing power of about ₹8,375 after ten years and ₹4,675 after twenty — a loss of nearly 69% over two decades.
The withdrawal needed in year n to hold purchasing power constant is:
W_n = W_0 \times (1 + i)^nWhere W0 is your starting withdrawal and i is the inflation rate.
| Year | Withdrawal needed to match ₹15,000 today (6% inflation) |
|---|---|
| Start | ₹15,000 |
| 5 | ₹20,073 |
| 10 | ₹26,863 |
| 15 | ₹35,948 |
| 20 | ₹48,107 |
By year twenty you need more than three times the starting withdrawal for the same standard of living — which changes the sustainability picture considerably compared with a flat withdrawal.
The calculator above models a fixed withdrawal. To plan a rising one, either recalculate periodically with the higher amount, or size your initial withdrawal conservatively enough to absorb increases later. Convert today’s expenses into future rupees with the Inflation Calculator.
SWP vs Fixed Deposit
| Feature | SWP (mutual fund) | Fixed deposit |
|---|---|---|
| Return potential | Market-linked, typically 8–12% | Fixed, typically 6–7.5% |
| What is taxed | Gain portion of each redemption only | Full interest earned |
| Tax rate | 12.5% above ₹1.25 lakh exemption (long-term equity) | Your income slab rate |
| Inflation protection | Partial, through equity growth | None — real returns often negative after tax |
| Flexibility | Adjust or stop any time | Penalty on premature closure |
| Capital certainty | Market risk; corpus can fall | Principal protected |
| On death | Remaining corpus passes to nominee | Passes to nominee |
The trade is real: SWP offers better post-tax income and inflation protection, and accepts market risk in exchange. An FD guarantees the rupee amount and guarantees losing purchasing power to inflation and tax.
SIP to SWP — the Full Lifecycle
Accumulation. Invest monthly through a SIP during your earning years.
Distribution. At retirement, switch to SWP and draw income while the remainder keeps compounding.
Worked through:
- ₹10,000 per month via SIP for 25 years at 12% → corpus of about ₹1.89 crore
- Start an SWP of ₹60,000 per month at an 8% return
- That corpus generates about ₹1,26,509 per month at 8%, well above the ₹60,000 withdrawal
- Result: the corpus grows indefinitely rather than depleting
The withdrawal here is 3.8% per year — inside the conservative band even before inflation increases. To reach a larger corpus with the same monthly strain, model annual increases with the Step-Up SIP Calculator.
Who Should Use This Calculator
- Retirees replacing a salary with monthly income from an accumulated corpus
- Early retirees modelling corpus longevity across long horizons
- Parents funding education costs through fixed annual withdrawals
- Anyone comparing SWP against an FD or annuity on a post-tax basis
- Advisors running quick scenarios during client conversations
Before You Start an SWP
- Use a conservative return assumption. 8–10% rather than peak historical figures. Test the plan at both and check it survives the lower one.
- Check the exit load and consider waiting twelve months after investing before starting withdrawals.
- Keep a liquid buffer of two to three years of withdrawals outside the SWP corpus, to avoid selling equity units during a downturn.
- Track your annual gain against the ₹1.25 lakh exemption. Splitting withdrawals across financial years, or across family members’ folios, can keep you under it for longer.
- Review annually. Adjust the withdrawal based on actual returns and actual expenses rather than the original projection.
- Match the fund to the horizon. Balanced advantage and equity savings funds for long horizons; debt or liquid funds where the SWP runs under three years.
Assumptions and Limits
- A constant annual return is applied. Real returns vary, and the sequence in which they arrive materially affects the outcome — see the section above.
- Withdrawals are fixed in rupee terms; inflation increases are not modelled.
- Tax is not deducted from the calculator’s output. The tax section above works through the actual figures.
- Exit load is not modelled.
- Results are projections, not guarantees.
Mutual fund investments are subject to market risk. Read all scheme-related documents carefully. This calculator is an estimation tool, not investment advice.

An SWP is a mutual fund facility that automatically withdraws a fixed amount at regular intervals — usually monthly — from your invested corpus, while the remaining units stay invested and continue earning. It is commonly used to convert a retirement corpus into a salary-like monthly income without redeeming everything at once.
Far less than most people expect, because only the capital gains portion of each withdrawal is taxable — not the full amount. On a ₹20 lakh corpus with ₹15,000 monthly withdrawals at 10%, total tax across fifteen years works out to roughly ₹4,937, about 0.18% of everything withdrawn. The gain component of each year’s withdrawals stays below the ₹1.25 lakh long-term exemption until around year thirteen. Equity units held over twelve months are taxed at 12.5% above that exemption; units held twelve months or less at 20%.
Redemptions follow FIFO — first in, first out. Units held for twelve months or less are short-term and taxed at 20%, while units held longer are long-term and taxed at 12.5% above the ₹1.25 lakh annual exemption. For a lumpsum invested on one date, all units cross twelve months together, so only your first year of withdrawals is short-term. The gain portion is smallest in that year, so the actual cost is usually under ₹2,000. Starting the SWP twelve months after investing avoids it entirely, and also avoids the exit load.
At a 4% annual rate — the conservative benchmark — that is about ₹16,667 per month, rising with inflation each year. At 5% it is roughly ₹20,833 and at 6% about ₹25,000. Higher rates work if returns cooperate, but they leave less margin if a poor stretch arrives early. Run your own figures above and check the plan still holds at a lower return assumption.
In principle, yes. If your annual withdrawal is smaller than the annual return, the corpus grows faster than it depletes. A ₹1 crore corpus earning 10% can sustain roughly ₹83,000 per month indefinitely at a constant return. Two caveats: real returns are not constant, and a fixed withdrawal loses purchasing power to inflation, so a plan that looks perpetual in nominal terms may not be in real terms.
It is the risk that poor returns arriving early in a withdrawal plan do lasting damage, because you sell units at depressed prices and those units cannot recover. The same set of returns in a different order produces a materially different outcome once withdrawals begin — while during accumulation, order makes no difference at all. Holding two to three years of withdrawals in a liquid fund, and drawing from that during downturns, is the standard defence.
On post-tax income, generally yes. FD interest is fully taxed at your slab rate, while an SWP is taxed only on the gain portion of each redemption and benefits from the ₹1.25 lakh annual exemption. In year one on comparable income, an SWP might cost around ₹1,890 in tax against roughly ₹42,000 on an FD for a 30% taxpayer. The trade-off is market risk: an FD guarantees the rupee amount, while an SWP corpus can fall in value.
SIP builds wealth — you invest a fixed amount every month. SWP distributes it — you withdraw a fixed amount every month from an existing corpus. Most investors run SIPs through their earning years and switch to an SWP at retirement.
With IDCW, the fund house decides the timing and amount, and payouts are taxed at your slab rate as income from other sources. With an SWP you control the amount and frequency, and the withdrawal is treated as a redemption taxed under capital gains rules — which for equity funds held over twelve months is usually far more favourable.
For horizons over ten years, balanced advantage and equity savings funds are common choices, blending equity growth with lower volatility than pure equity. For horizons under three years, debt or liquid funds reduce the risk of a fall arriving just as you start withdrawing. The right choice depends on your horizon, risk tolerance, and tax bracket.
Final Thoughts
The arithmetic of an SWP is simple: while your return rate exceeds your withdrawal rate, the corpus is preserved and often grows. In the example on this page, ₹20 lakh paid out ₹27 lakh over fifteen years and still finished at ₹26.9 lakh.
Two things decide whether that holds in practice — the withdrawal rate you choose, and whether you can avoid selling into a downturn early on. Get those right and the tax efficiency takes care of itself.
