A retirement corpus does not pay a monthly income on its own. You convert it into income using one or more of four routes: a systematic withdrawal plan (SWP) from mutual funds, a bucket strategy that separates cash from growth, an annuity that pays a fixed pension for life, and the interest or dividends a portfolio throws off. Most retirees blend them rather than pick one.
Accumulation and decumulation are different skills. For decades you build a lump sum; then you have to make it release a reliable monthly amount that lasts as long as you do, through good markets and bad.
Numbers behind retirement income
A systematic withdrawal plan (SWP)
The most common tool is an SWP, which redeems a fixed rupee amount from a mutual fund on a set date each month while the rest stays invested. It is the reverse of an SIP, and the what is an SWP guide covers exactly how it works and how it is taxed.
The point for retirement is sustainability. An SWP lasts only if the withdrawal rate stays below the corpus's long-run growth, with a buffer for weak years. The income is market-linked, not guaranteed, so the rate you choose matters more than the fund you pick. The SWP calculator lets you test how long a corpus survives at a given withdrawal rate and return assumption.
The bucket strategy
A bucket strategy splits the corpus by when you will spend it.
- A cash bucket holds one to three years of expenses in a savings account, liquid fund or short-term deposit, so your near-term spending never depends on the market.
- A stability bucket holds a few more years of spending in debt instruments.
- A growth bucket keeps the long-term money in equity, where it has time to recover from falls.
You spend from cash, and periodically refill it from the other buckets when markets are kind. The purpose is behavioural as much as financial: it stops you selling equity in a crash to pay next month's bills.

An annuity floor for essentials
An annuity converts a lump sum into a fixed income for life, bought from a life insurer. Used as a "floor", you annuitise just enough to cover non-negotiable expenses (food, utilities, medicines), so those are covered by a fixed insurer payout rather than by market returns, and keep the rest of your corpus invested for growth and flexibility.
Annuity rates are set by insurers and currently sit broadly in the mid-single digits; the income is taxed as income, and the capital is locked once you buy. That trade, certainty for liquidity, is the whole decision. An NPS exit forces a version of this by requiring at least 40% of the corpus to buy an annuity at 60. For a smaller fixed pension, the Atal Pension Yojana plays a similar floor role.
Interest and dividends
Some retirees try to live only off the income their assets produce, interest from deposits and bonds, dividends from stocks or funds, without touching the capital. It is simple and leaves the corpus intact, but the income is uneven: interest rates fall, dividends are not guaranteed and can be cut, and a pure-income approach often needs a much larger corpus to generate enough. It usually works best as one stream among several, not the whole plan.
The risk that quietly breaks a plan: sequence of returns
Two retirees with the same average return can end up very differently if the order of returns differs. A market fall in the first few years of retirement, while you are withdrawing, does far more damage than the same fall later, because you sell more units when prices are low and the corpus never fully recovers. This is sequence-of-returns risk, and it is the reason the cash bucket and the annuity floor exist: they let you leave investments untouched precisely when selling would hurt most.
| Approach | What it gives | The catch |
|---|---|---|
| SWP | Flexible, tax-efficient monthly income | Market-linked, not guaranteed |
| Bucket strategy | Shields near-term spending from crashes | Needs periodic rebalancing |
| Annuity floor | Fixed income for life | Capital locked, mid-single-digit rates |
| Interest and dividends | Keeps capital intact | Uneven, needs a larger corpus |

Building a corpus asks one question: how do I grow this? Drawing an income asks a harder one: how do I spend it without running out? The answer is rarely a single product. It is a structure, a floor for what you must pay, growth for what you hope to, and cash so a bad year never forces your hand.
