SWP vs Fixed Deposit: How the Income Compares

Both a Systematic Withdrawal Plan and a fixed deposit turn a lump sum into a monthly income. That is where the similarity ends. One pays a rate fixed in advance and hands back the full amount taxed at your slab; the other pays a variable amount drawn from an investment, taxed on the gain alone. Comparing them on the headline rate misses almost everything that actually decides which one leaves more in your pocket.

How each one actually works

A fixed deposit is a loan you make to a bank. You hand over a lump sum for a fixed tenure at a rate agreed up front — currently in the region of 6% to 7.5% for most banks, roughly 0.5 percentage points higher for senior citizens — and the bank pays that rate regardless of what happens in the markets. On a monthly-payout FD, the interest is paid out every month and the principal comes back, untouched and unchanged, at maturity.

An SWP instead redeems a fixed rupee amount of mutual fund units every month, as covered in what SWP is and how it works. There is no agreed rate: the units you hold are worth whatever the fund's NAV says on the withdrawal date, and the remaining balance keeps moving with the market, up or down, for as long as the plan runs.

The tax difference is the whole game

FD interest is fully taxable at your income tax slab, with no distinction between principal and return — the entire amount you receive each year is added to your income. Banks also deduct TDS at 10% once annual interest crosses ₹50,000 for most depositors, or ₹1 lakh for senior citizens, under Section 194A. That TDS is only a matter of timing, not your final liability, and can be avoided upfront by filing the self-declaration Form 121 — the single form that replaced both Form 15G and Form 15H from April 2026 — if your total income is below the taxable threshold.

An SWP is taxed completely differently. Because each withdrawal is legally a redemption, only the capital gain embedded in it is taxable, not the full amount — and for equity mutual funds that gain is taxed at a flat rate regardless of your income slab: 12.5% above a ₹1.25 lakh exemption per financial year for long-term gains, 20% for short-term. Mutual funds also do not deduct any TDS on SWP redemptions for resident Indian investors, so the entire cash-flow timing question that applies to FDs simply does not arise here.

The consequence is that the tax gap between the two widens sharply as income rises. Someone in the 30% slab loses close to a third of every rupee of FD interest to tax, while an equity SWP investor pays a flat 12.5% on the gain portion only — often a fraction of the withdrawal once the annual exemption is applied. Someone in the 5% slab, or a senior citizen using the ₹50,000 Section 80TTB deduction on interest income, sees a much smaller gap, and may find the FD perfectly competitive after tax.

What ₹1 crore actually pays, after tax

Take a ₹1 crore corpus — the same figure used throughout this SWP series — run through both structures.

• A monthly-payout FD at 7% pays about ₹58,333 a month before tax. At the 30% slab, after-tax income is roughly ₹40,800; at the 20% slab, about ₹46,700; at the 5% slab, about ₹55,400.
• An SWP of ₹50,000 a month from an equity fund, where — for illustration — half of each redemption is capital gain, realises about ₹3 lakh of gain a year. After the ₹1.25 lakh exemption, ₹1.75 lakh is taxed at 12.5%, or roughly ₹21,875 a year — about ₹1,800 a month. After-tax income comes to approximately ₹48,200, regardless of which income slab you are otherwise in.

The FD's higher gross payout is precisely what makes it look better before tax and precisely why the comparison has to be made after tax. The proportion of an SWP redemption that counts as gain rather than return of principal varies with how long the fund has run and how it has performed, so treat the 50% split above as an illustration rather than a rule — running your own numbers against your actual holding gives the real figure.

What happens to the money itself

A monthly-payout FD returns exactly the principal you put in at maturity — no more, no less — because the interest is paid out as it accrues rather than added to the balance. The corpus neither grows nor shrinks in nominal terms; it simply sits, earning a fixed rate, until the tenure ends and you decide whether to renew at whatever rate is then on offer.

An SWP's corpus can do either. If the fund's return outpaces the withdrawal rate, the balance grows even while you draw an income from it. If the withdrawal rate is too high relative to the return, the balance shrinks, and the shrinkage accelerates as the base available to grow gets smaller each month — the exact mechanics covered in how long an SWP can last. An FD never depletes on its own; an SWP can run to zero if the numbers do not support it.

Safety net: deposit insurance versus market risk

Bank deposits, FDs included, are protected by DICGC deposit insurance up to ₹5 lakh per depositor per bank — principal and interest combined — even if the bank itself fails. Spread across accounts at different banks, that limit resets each time, which is one reason large FD holdings are often split across institutions rather than concentrated in one.

Mutual fund units carry no equivalent insurance, and none is needed in the same sense — the fund holds securities on your behalf rather than owing you money as a creditor, so there is no counterparty failure risk of the kind DICGC exists to cover. What an SWP does carry is market risk: the value of what you hold moves with the underlying securities, and a downturn early in the withdrawal phase can permanently dent the corpus in a way a fixed-rate deposit simply cannot.

Which one actually suits you

Neither structure is universally better; they answer different priorities. An FD suits money you cannot afford to see fall in value over the period you need it, and suits investors in low tax slabs where the tax gap barely matters. An SWP suits money that can tolerate market movement in exchange for substantially better tax treatment and a real chance of growing rather than merely being preserved — which matters more the longer the withdrawal period and the higher your tax slab.

Many retirees do not choose one exclusively. A common approach keeps one to three years of planned expenses in FDs as a spending buffer, insulated from market swings, while the remainder runs an SWP for its tax efficiency and growth potential — spending from the safe bucket during a downturn rather than being forced to redeem fund units at depressed prices. Compare the two structures against your own numbers with the SWP calculator and the FD income calculator before deciding how to split.
