SWP Calculator: Turn ₹1 Crore Into a Monthly Salary — Tax, Math and 3 Rules

What if your mutual fund paid you a salary every month — the way your job did? That is exactly what a Systematic Withdrawal Plan, or SWP, is designed to do. You invest a lump sum once, and the fund pays out a fixed amount to your bank account on a schedule you choose — monthly, quarterly or yearly. India's retirees have quietly adopted it: while everyone watches record SIP inflows (₹31,781 crore in June 2026 and ₹30,954 crore in May 2026, per AMFI data reported by way2wealth), equity redemptions have been climbing too — ₹44,824 crore in July 2026, up 38% year-on-year (Hindu BusinessLine, ~Aug 15, 2026). A meaningful share of that is money moving from "growth mode" to "income mode". This guide explains the SWP math, the current tax rules, and three rules that keep the income running — plus a calculator you can use right inside this article.

QUICK ANSWER: An SWP (Systematic Withdrawal Plan) lets you withdraw a fixed amount from your mutual fund corpus at regular intervals. The fund automatically redeems the required units at the prevailing NAV and credits your bank. Withdrawals of up to 4–6% of the corpus per year are commonly cited as sustainable, but only the gains portion is taxed (equity: 20% STCG up to 12 months, 12.5% LTCG above ₹1.25 lakh/year). You can pause, modify or stop an SWP anytime.

If a SIP is drip-feeding money into a fund, an SWP is drip-feeding money out. You invest a lump sum — say ₹1 crore — into a mutual fund. You then set a withdrawal instruction: ₹50,000 on the 5th of every month, for example. On each date, the fund automatically redeems whatever number of units equals ₹50,000 at that day's NAV, and the cash lands in your bank account. The plan runs until you cancel it, the scheduled instalments finish, or the units are exhausted. And yes — you can pause, modify or stop it at any time (ClearTax's SWP guide and LiveMint's retirement explainer both confirm this flexibility). Here is the mechanic that makes SWP elegant, and the one most articles skip. The units redeemed each month are not fixed — only the rupee amount is. The Economic Times illustrates it neatly: you hold 8,000 units and withdraw ₹5,000 a month. At a NAV of ₹10, the fund sells 500 units. If the NAV rises to ₹15 next month, it sells only 333 units. HDFC Mutual Fund (updated Sep 18, 2026) calls this "reverse rupee-cost averaging": when the market is high you part with fewer units; when it is low you part with more. It is the exact mirror of SIP, where a fixed rupee amount buys more units when the NAV falls.

Try the numbers on your own corpus with the live SWP calculator above — set your corpus, monthly payout and expected return, and see roughly how long the money lasts.

This is the question every SWP article must answer with worked numbers, not adjectives. Start with the simplest sustainable-withdrawal illustration. If a ₹1 crore corpus earns 6% a year, it generates ₹6 lakh a year — ₹50,000 a month — without touching the principal in theory. That is the often-quoted "6% rule of thumb" illustration, and you can verify it against your own return assumption in the calculator.

Now a more realistic worked example, with the math shown step by step. Take a ₹1 crore corpus, assume 9% annual returns, and withdraw ₹40,000 a month (₹4.8 lakh a year — a 4.8% withdrawal rate): Year-end value before withdrawal: ₹1,00,00,000 × 1.09 = ₹1,09,00,000. Withdrawals during the year: ₹4,80,000. Year-end corpus: roughly ₹1,04,20,000 (simplified — monthly timing changes this slightly). The corpus grew even after paying you ₹4.8 lakh. That is how compounding plus a conservative withdrawal rate keeps an SWP running. But change the return to 4% and keep the same ₹4.8 lakh withdrawal, and the corpus shrinks to about ₹99.2 lakh at year-end — you are eating the principal. The lesson: the withdrawal rate must sit comfortably below your expected return, with margin for bad years. All figures here are illustrations, not predictions; actual fund returns vary and past performance does not indicate future results.

What rate, then? Moneycontrol's SWP guide (crawled Sep 29, 2026) cites 4–6% of the corpus per year — ₹50 lakh supports roughly ₹16,000–25,000 a month. Upstox adapts the famous 4% rule for India: ₹50 lakh supports about ₹16,667 a month in year one. But there is an important India-specific caveat several guides flag: with Indian inflation historically running 5–7%, longer horizons may need a more conservative 3–3.5% rather than the American 4%. Set your rate against your own time horizon and expenses — and if you are unsure, that is a conversation for a SEBI-registered investment adviser, not a calculator.

Here is the angle almost no SWP explainer ties to real markets, and it matters right now. The Nifty fell 5.67% in September 2026 — its worst September since 2018 (Business Standard). Imagine your NAV falls 10% while your ₹50,000 monthly payout stays fixed: the fund must sell 11% more units every month to produce the same cash. Fewer units remain to participate in the recovery. This is "sequence-of-returns risk". Two practical responses, both built into how SWPs work. First, temporarily reduce the payout during prolonged downturns — Moneycontrol explicitly suggests dialling down the SWP so unit erosion doesn't accelerate. Second, pause and draw from a buffer: keep 1–2 years of payouts in a liquid fund or FD, and switch the SWP off when equity NAVs are depressed. The flexibility to pause is the whole point of the instrument — use it.

A ₹30,000 monthly SWP feels comfortable today. At 6% inflation, in 10 years you will need about ₹54,000 a month to buy the same things (30,000 × 1.06^10 ≈ ₹53,725). Fixed withdrawals lose purchasing power silently — the most underrated SWP risk in Indian guides. Two defences: choose the inflation step-up variant that several funds offer, where your monthly payout rises by a fixed percentage (say 5–6%) each year automatically; or review the amount annually and step it up manually. Either way, build inflation into the withdrawal rate from day one.

An all-equity fund gives the highest long-term growth but also the wildest NAV swings — which means the most volatile unit erosion. For money you depend on monthly, many retirement guides (LiveMint's SWP table hints at this) suggest conservative hybrid or equity-savings funds as the SWP engine: 10–35% equity with the rest in debt and arbitrage. Returns are lower than pure equity, but the NAV path is smoother, so fewer units get sacrificed in bad months. A common Indian retiree playbook: keep 2–3 years of payouts in liquid/short-duration debt, run the SWP from a conservative hybrid fund, and review annually. Which fund and what mix suits your situation depends on your risk profile and horizon — again, adviser territory.

SWP withdrawals are not tax-free, and the rules changed recently enough that many guides are outdated. Here is the current position.

Equity funds (Budget 2024, effective July 23, 2024): gains on units held up to 12 months are taxed as short-term capital gains at 20%; gains on units held longer than 12 months are long-term, taxed at 12.5% on gains above ₹1.25 lakh per financial year (CNBC TV18, July 24, 2024; ET Now budget recap). Two things people miss: only the gains portion of each withdrawal is taxed — withdraw ₹15,000 where ₹10,000 is principal and only ₹5,000 of gains is taxable (LiveMint, citing Clear Tax) — and there is no TDS on SWP payouts, unlike FD interest. Budget 2025 and Budget 2026 made no further changes to these rates (financechecks.com, "Mutual Fund Taxation 2026," updated ~Aug 2026).

Debt funds (the surprise): for funds with less than 35% in domestic equity bought on or after April 1, 2023, all gains are deemed short-term and taxed at your income-tax slab rate, regardless of holding period — no indexation (Economic Times and ET Now, March 2023; the rule was designed to bring parity with bank FDs). Units bought before April 1, 2023 keep the old rules. Practical takeaway: a debt-fund SWP started today has zero tax advantage over FD interest — something many retirees still don't know.

The ₹1.25 lakh structuring point: because long-term equity gains up to ₹1.25 lakh a year are exempt, you can structure yearly withdrawals to book gains under the exemption (rupeezy.in LTCG guide, updated Sep 2026) — e.g. spread redemptions across financial years rather than bunching them. Tax law is intricate; confirm your plan with a chartered accountant.

- SIP vs SWP: SIP builds the corpus (accumulation); SWP spends it (distribution). Most investors will use both in sequence — SIP for 15–20 years, SWP after. Upstox's SIP+SWP guide frames them as the two halves of one journey. - SWP vs FD monthly income: FD interest is fully taxable at your slab rate with TDS; equity-SWP gains get the 12.5%-above-₹1.25L treatment with no TDS, and the corpus keeps market upside. But FD principal is protected; SWP corpus can fall. Compare post-tax, post-inflation numbers for your slab — not headline rates. - SWP vs dividend plans: dividends from mutual funds are taxed at your slab rate in the year received; SWP lets you control timing and tax character of each withdrawal. For most income-seekers, SWP is the cleaner instrument.
