SWP vs FD Interest — Monthly Money From Two Different Machines

A deposit paying monthly or quarterly interest keeps the principal intact and pays you the interest it earns. The rupee amount of capital never falls, and the monthly income is decided by the rate at the time of booking.

A systematic withdrawal plan redeems a fixed amount from a scheme on a set date each month. You choose the amount. Units are sold to pay it, and the remaining units stay invested, as our page on the systematic withdrawal plan explains.

So a deposit pays you what the capital earns. A withdrawal plan pays you what you ask for, drawn from capital and growth together, and whether the remainder grows or shrinks depends on markets and on whether you are withdrawing more than the holding earns.

Certainty, and it is worth a great deal to a household that has stopped earning.

The amount of interest is known at booking. The capital does not move. There is no month in which a statement shows less than was put in. For money that must be available on specific dates, that is exactly the right characteristic, and our page on mutual funds versus fixed deposits sets out where it fits.

The weakness is quiet. A fixed rupee amount buys less each year, and a retirement that lasts twenty-five years is long enough for that erosion to become the main problem rather than a detail. Our page on inflation and your savings is about precisely that.

Control and the possibility of keeping pace.

You set the monthly amount rather than accepting whatever a rate produces, and you can raise it, lower it or pause it without breaking anything. If the underlying scheme holds some growth assets, the remaining capital has a chance of growing over a long retirement rather than steadily losing buying power.

The weakness is that the value moves. In a poor year the plan is selling units at lower prices to meet the same monthly amount, which depletes the holding faster. That sequence problem is real and it is the main thing to plan around, as our page on early retirement explains in detail.

The most workable arrangement we see splits the retirement money by when it will be spent.

The first few years of spending sit somewhere certain, which is what deposits and the very short end of the debt ladder are for. That removes the risk of being forced to sell growth holdings during a bad stretch at the start of retirement.

Money for later years stays in holdings that can grow, and a withdrawal plan draws from them once the near-term money has been used. As each year approaches, money moves from the growth side to the certain side on a schedule.

This is not a clever product. It is simply matching money to dates, which our page on asset allocation sets out as the method for everything.

The single most important decision in a withdrawal plan is how much to take, and it is the one people set by what they would like to spend rather than by what the holding can sustain.

Withdrawing more than a holding earns over time means the capital shrinks, and a shrinking capital earns less the following year, which accelerates the decline. Withdrawing less leaves room for bad years to pass.

We do not publish a safe figure, because any figure depends on assumed returns and assumed inflation that nobody knows. What we would say is that a withdrawal amount which requires good markets to be sustainable is not a plan for retirement, and that reviewing the amount every year is part of the arrangement rather than an admission that something failed.

The two are treated differently, and the difference is structural rather than a matter of rates.

Deposit interest is generally taxed as income as it accrues. A withdrawal plan is a series of redemptions, and each redemption is a sale in which only the gain portion is relevant, calculated according to the holding period of the units sold. For many retired households that difference is meaningful.

How it applies to you depends on your income, the scheme type and the rules at the time, which have changed before. Our page on mutual fund taxation covers the structure, and your own position belongs with a tax adviser.

One consideration that rarely enters the conversation and should.

In many households one partner handles the money and the other survives them, sometimes by a decade or more, and inherits an arrangement they did not design. A withdrawal plan that needs annual review is only as good as the person able to do that review.

So whoever is likely to be managing this in their eighties should understand it now, and the nominations on every holding should be current, as our page on nomination covers. Our page on investing as a working woman discusses why this falls on women more often than on men.

We are distributors rather than investment advisers, and a close-ended scheme considered for this purpose deserves particular care, as our page on open-ended versus close-ended funds explains. Get in touch if you want to work through the split.
