SWP vs FD for Monthly Income: Which Is Better for Retirement?

If you have a lump sum, from retirement, a property sale or years of saving, and want a monthly income from it, the two usual choices are:

• A fixed deposit with monthly interest: predictable income, and your principal stays the same.
• A systematic withdrawal plan (SWP) from a mutual fund: you choose a fixed monthly amount, and the fund sells units to pay it. The rest stays invested.

Here's how they compare on a ₹50 lakh corpus.

The fixed deposit route

At 7% a year with monthly payout, ₹50 lakh pays ₹29,167 a month. The principal stays at ₹50 lakh, and you get it back at maturity.

The catch is inflation. At 6% inflation, ₹29,167 buys only about half as much after 12 years, and your FD income never rises to make up for it. Prices also go up while the principal stays the same, so the corpus itself loses value.

The SWP route

Suppose you invest ₹50 lakh in a fund that averages 10% a year and withdraw ₹30,000 a month:

Each row assumes 10% a year.

At ₹30,000 a month, a little more than the FD pays, the corpus more than doubles in 20 years, because the fund earns more than you take out. You could withdraw up to about ₹46,832 a month and still last exactly 20 years.

If returns average 8% instead of 10%, ₹30,000 a month still leaves ₹62,34,814 after 20 years.

Tax: where SWP shines

FD interest is fully taxable at your slab rate every year, whether you spend it or not.

SWP withdrawals are mostly a return of your own money. Only the gain in each withdrawal is taxed:

• Equity funds held over 12 months: gains above ₹1.25 lakh a year are taxed at 12.5%. Below ₹1.25 lakh, they're tax-free.
• Equity funds held 12 months or less: gains are taxed at 20%.
• Debt funds bought after 1 April 2023: gains are taxed at your slab rate, like FD interest, but only when you redeem.

In the early years of an SWP from an equity fund, most of each withdrawal is your own money coming back. The gains often stay under the ₹1.25 lakh exemption, so the income can be nearly tax-free.

Where FD wins: certainty

The SWP figures above assume steady returns. Markets don't work like that:

• Sequence risk. A 30% market fall in the first two years, while you keep withdrawing, can permanently shrink the corpus. Withdrawals sell more units when prices are low.
• No guarantee. An FD's income is fixed from day one. SWP returns can be negative in a bad year.
• Behaviour. Watching a corpus fall during a crash, and not stopping the SWP in panic, takes discipline.

A balanced approach

Many retirees combine the two:

1. Two to three years of expenses in FDs, a liquid fund or SCSS, for certain income in the short term.
2. The rest in a hybrid or balanced advantage fund (or an equity–debt mix), with an SWP of about 4–6% of the corpus a year.
3. Refill each year. Top up the safe bucket from the SWP fund in good years, and pause refills after market falls.

This gives FD-like certainty for the next few years and inflation-beating growth for the decades after.

Who should choose what

• FD (or SCSS): if you need every rupee of income fixed, have a short horizon, or can't tolerate seeing the corpus fall.
• SWP: if your retirement may last 20–30 years, you want the income to keep up with inflation, and you can hold through bad years.
• Both: most people, using a safe bucket plus a growth bucket.

Run your own numbers

The SWP calculator shows how long your corpus lasts for any withdrawal, return and annual increase, and the maximum safe withdrawal. Compare it with fixed income options in the FD calculator and the SCSS calculator.

Mutual fund returns are not guaranteed and investments are subject to market risks. The figures above assume constant returns for illustration.
