SIP + SWP Calculator

A SIP and an SWP are the same account pointed in opposite directions at different times of your life: one pays into a fund on a fixed schedule while you are earning, the other sells units on a fixed schedule to pay you back once you are not. This runs both halves as one plan — each with its own frequency, from weekly to yearly — and shows the corpus you build, how long it then funds your withdrawals, and what capital-gains tax takes when you switch the simulator on.

One plan, two halves

Most people meet SIPs and SWPs as separate products on separate pages, which hides the thing that matters: they are the same account, running in opposite directions at different times of your life. A Systematic Investment Plan pays a fixed sum into a fund on a fixed schedule. A Systematic Withdrawal Plan sells enough units on a fixed schedule to pay a fixed sum back out. The corpus the first builds is the corpus the second spends.

Modelling them together is the only way to answer the question anyone actually has. Not “what will my SIP be worth” and not “how long will a corpus last”, but whether the amount you can afford to pay in now funds the income you will want later, for as long as you will want it. That answer is a shape, and it is the shape the chart on this page draws: a climb, a peak, and a fall that either reaches the end or does not.

What the frequency dropdowns change

Each half keeps its own schedule. The amount you type is one instalment or one withdrawal on that schedule, so the same yearly outlay looks very different depending on which you pick — ₹5,769 a week and ₹3,00,000 a year are the same commitment.

A period earns the annual rate divided by the number of periods in a year, and money moves at the start of each period. That is the nominal convention the Indian industry quotes returns in, and it is why a monthly plan here agrees exactly with the standalone SIP and SWP calculators.

₹1,50,000 a half-year₹1,50,000₹2.46Cr
₹3,00,000 a year₹3,00,000₹2.42Cr

Paying in more often finishes slightly ahead, because the same nominal rate compounds more times. The spread across all five schedules is under 3.4% over twenty years — real arithmetic, but far too small to be a reason to change how you pay. Pick the schedule that matches when your money actually arrives.

How long the corpus lasts

The withdrawal rate — your first withdrawal as a percentage of the corpus, annualised — is the single number that decides this. It matters far more than the return you assume, because a rate above the real return means the corpus is shrinking from day one and every later withdrawal takes a larger bite of what is left.

5%₹1,04,078Past 25 years
6.5%₹1,35,301Past 25 years
8%₹1,66,52518.3 years

3.5% is usually sustainable for 30 years or more; 6.5% is typically runs 18–22 years. Those are rules of thumb drawn from how real sequences of returns have behaved, not guarantees — which is exactly what a projection at one flat rate cannot capture.

Time on the paying-in side

Every year you add at the start is a year of compounding on every instalment that follows it. The corpus column below grows far faster than the invested column, and the last column — what that corpus safely pays out — grows with it.

25 years₹75.00L₹4.74Cr₹1,38,369
30 years₹90.00L₹8.82Cr₹2,57,390

Stepping the instalment up matters nearly as much as starting early. The same ₹25,000 a month raised 10% a year for 20 years builds ₹4.97Cr rather than ₹2.50Cr — because each raise compounds on the one before it, and every raised instalment then compounds for the years that remain.

Why the handover carries lots, not a number

When the paying-in half ends, this calculator does not hand the withdrawal half a corpus and a cost. It hands it every instalment as its own lot: the units that instalment bought, the price it paid, and the date it paid. Withdrawals then redeem those lots oldest first, which is how a real fund does it.

That distinction is the whole of the tax answer. Units held more than 12 months are long-term; twelve months exactly is still short-term, because the rule is “more than”, not “at least”. On a corpus built by a SIP the oldest units are years past that line when the first withdrawal lands, so a SIP-built corpus is almost entirely long-term from the start — something a single blended cost basis cannot tell you, because it has thrown the dates away.

The flip side is that those oldest units were also the cheapest, so the gain realised on each early withdrawal is larger than a blended basis would suggest. The two effects pull in opposite directions, which is precisely why they have to be computed rather than assumed.

What tax takes, once you switch it on

The simulator starts off, because the first question is whether the plan stands up at all. Switched on, it prices each redemption under the current Indian rules: equity gains held past 12 months at 12.5% above a ₹1,25,000 allowance each financial year, anything shorter at 20%, and post-April-2023 debt funds at your slab with no allowance at all.

Two details are worth knowing. The allowance is consumed in the order gains happen through the year, so the page walks the schedule rather than aggregating it. And tax is treated as paid out of the withdrawal rather than by selling extra units — which is what actually happens, since there is no TDS on a resident's redemption and you settle it at filing. It also means the corpus line never jumps when you flip the toggle.

What this leaves out

  • One flat return stands in for every year, in each half. Real returns arrive in an order, and the order matters most once withdrawals have begun.
  • Expense ratios, exit loads and STT are not priced, nor is the gap between a fund and its index.
  • Cess is included in the tax figures; surcharge is not, as it depends on your total income. Capital losses are not carried forward.
  • A real plan transacts on a date at that day's NAV, so the units actually bought and sold depend on the path the price took rather than its average.
  • Balances shown in today's money are deflated at the inflation rate you set, which is an assumption like any other on the page.

Frequently asked questions

What is a SIP + SWP plan?

It is one plan run in two halves. A Systematic Investment Plan pays a fixed sum into a fund on a fixed schedule while you are earning; a Systematic Withdrawal Plan sells enough units on a fixed schedule to pay a fixed sum back out once you are not. The corpus the first half builds is the corpus the second half spends, which is why they belong on one page rather than two.

How do the weekly, monthly, quarterly, half-yearly and yearly options work?

Each half has its own schedule, set independently. The amount you enter is one instalment or one withdrawal on that schedule, so ₹5,000 weekly is ₹2.6 lakh a year while ₹5,000 quarterly is ₹20,000. A period earns the annual return divided by the number of periods in a year, and money moves at the start of each period — the same convention the monthly SIP and SWP calculators use, so a monthly plan’s instalments and withdrawals match them exactly. Money already invested is the exception: it grows by the period rate here, where the SIP & Lumpsum page compounds a lumpsum once a year, so the same amount ends higher on this page.

Why can a weekly plan finish slightly ahead of a monthly one?

Because it compounds more often at the same headline rate. Fifty-two periods of one fifty-second of the annual rate come to a little more than twelve periods of one twelfth, which is the nominal convention the whole Indian industry quotes returns in. The gap is small — a fraction of a percent a year — and it is arithmetic, not an argument for paying weekly.

Can I invest and withdraw at different frequencies?

Yes, and it is the common case. People usually pay in monthly because a salary arrives monthly, then draw quarterly or monthly in retirement depending on how they want their expenses covered. The two dropdowns are independent, and the handover between them carries the whole corpus across whatever schedules you pick.

What happens at the handover between the two halves?

Everything the paying-in half bought is carried over — not just its value, but every instalment as its own lot, at the price that instalment paid and dated the day it paid it. That is what makes the tax figures real: redemptions sell the oldest units first, so the calculator knows exactly which units went and how long they had been held.

Why does the tax simulator start switched off?

Because the first question is whether the plan works at all — whether the corpus you build is large enough to fund the withdrawals you want for as long as you want them. Tax narrows the answer rather than changing its shape. Switch it on once the plan stands up, and the page prices each redemption under the current Indian capital-gains rules.

How is the tax on withdrawals calculated?

For equity funds, gains on units held more than twelve months are long-term and taxed at the long-term rate above a yearly exemption, which is applied per financial year in the order gains are realised; gains on units held twelve months or less are short-term at the higher rate. Debt funds bought after April 2023 are taxed at your slab with no exemption. The health and education cess is included; surcharge is not, since it depends on your total income.

Does a SIP-built corpus get taxed differently from a lumpsum?

On the long-term side, usually more favourably at the start. First-in-first-out means the units sold first are the ones bought first, which are both the oldest and — in a rising market — the cheapest. They clear the twelve-month holding test comfortably, so almost nothing is short-term. Their low cost does mean the gain on each redemption is larger, which is why the calculator tracks lots rather than applying a blended profit ratio.

Why are there two expected-return sliders?

Because the two halves are usually two different portfolios. Money still being accumulated is normally held harder — more equity, more volatility, a longer horizon to absorb it — while money being spent is normally held more conservatively. A drawdown is also far more sensitive to an optimistic rate than an accumulation is, so tying both to one number would flatter the result.

What is a safe withdrawal rate?

The first withdrawal as a percentage of the corpus, annualised. Long-horizon retirement work treats the conservative end of 3–4% as defensible over thirty years; higher rates shorten the plan quickly. The page labels your rate against those bands, but they are rules of thumb drawn from historical sequences, not a guarantee about the next thirty years.

What does the gap before the first withdrawal do?

It leaves the corpus invested, untouched, between the last instalment and the first withdrawal — time added on top of the drawing-out years, not taken from them. Two things follow: the corpus grows for longer, so the same withdrawal is a smaller share of it, and the units have been held longer when they finally go, which can move gains from short-term to long-term. On a SIP-built corpus the second effect is usually small, because the oldest units are already well past twelve months.

Should the withdrawals step up each year?

If you want them to keep buying the same things, yes — a flat withdrawal loses purchasing power at the inflation rate every year, and over a twenty-five-year retirement that is most of it. Stepping withdrawals up in line with inflation is the honest default; the trade is that the corpus drains faster, which the chart shows immediately.

Does this match what my fund house will show?

It will be close but rarely identical. This treats each instalment and each withdrawal as landing at the start of its period at a single flat return. A real plan transacts on a specific date at that day’s NAV, so the units actually bought and sold depend on the path the price took, not just its average. Expense ratios, exit loads and STT are not priced here.

Is the money I withdraw taxed as income?

No. A withdrawal from a mutual fund is a redemption, not income, so only the gain embedded in the units you sold is taxable — the capital you originally put in comes back untaxed. That is the structural reason an SWP is usually taxed more lightly than a fixed deposit paying the same amount, where every rupee of interest is taxable in the year it accrues.

What if the corpus runs out before the end?

The page says which month it happens and offers the largest starting withdrawal that would have lasted the full term instead. That figure is solved exactly rather than searched for, and it is rounded down — rounding a sustainable withdrawal up is precisely what stops it being sustainable.
