What you are actually buying
You hand an insurer a lump sum. In exchange it pays you a stated amount for the rest of your life, however long that turns out to be.
The capital is generally gone — under a plain lifetime annuity there is nothing to leave behind, and that is not a defect. It is the price of the guarantee, and the guarantee is the product.
Every other retirement instrument leaves you exposed to one specific risk: living longer than your money. A corpus with an SWP can be exhausted. A deposit ladder runs out. An annuity is the only ordinary instrument where that cannot happen, because the obligation to pay you does not end until you do.
Why the pool can pay more than you could yourself
Here is the mechanism that makes annuities work, and it is almost never explained.
An insurer sells the same annuity to thousands of people of similar age. It knows roughly how long the group will live, even though it knows nothing about any individual. Some die early; some live far longer than average.
The capital of those who die early funds the payments to those who live long. That transfer is called a mortality credit, and it is real money that has no equivalent in a portfolio you manage yourself. Managing your own corpus, you must plan for the possibility of living to ninety-five — and so must every other retiree independently, which means everyone holds back for a scenario most will not reach.
Pooling removes that duplication. It is the same logic as any insurance: the many who do not claim fund the few who do. Here the “claim” is an unusually long life.
So the honest comparison is not annuity return versus market return. It is annuity income versus what you could safely withdraw from a corpus that has to last an unknown time — and once framed that way the gap narrows considerably, because the self-managed version must be conservative precisely where the annuity does not.
The options, and what each costs
| Option | What it adds | Effect on the payout |
|---|---|---|
| Life annuity | Nothing — income until death | Highest payout |
| Joint life | Continues to a spouse | Lower, since two lives are covered |
| Return of purchase price | The capital returns to your nominee | Substantially lower |
| Guaranteed period | Pays for a minimum number of years regardless | Slightly lower |
| Increasing annuity | Payment rises at a set rate each year | Much lower to begin with |
Two of these deserve comment.
Return of purchase price is the most popular option in India and the one that most undermines the point. Getting the capital back for your heirs means the insurer is not using it to fund payments, so the income drops sharply — and you have effectively turned a longevity product into a low-yielding deposit with an estate feature. If leaving money behind is the objective, term insurance does it far more efficiently.
The increasing annuity addresses the real weakness below, and it starts much lower. Whether the trade is worth it depends on how long you expect to receive it, which is exactly the thing nobody knows.
The genuine weaknesses
Three, and none of them is “the return is low”.
Inflation. A level annuity pays the same rupees for decades, and inflation halves purchasing power roughly every twelve years at 6%. An income that is comfortable at sixty may be inadequate at eighty. This is the strongest argument against putting an entire corpus into one.
Irreversibility. Once purchased, it generally cannot be undone. If circumstances change — a large medical need, a family emergency — the capital is not there to access. Flexibility has been sold, deliberately, and it cannot be bought back.
Rate at purchase. The payout is fixed by rates on the day you buy. Annuitising a whole corpus at one moment concentrates that timing risk, which is an argument for buying in tranches over several years rather than all at once.
Counterparty risk is worth a mention and is generally the smallest of the four: you are relying on an insurer to pay for decades, which is why the insurer's standing matters more here than on a short-term product.
How they are actually used well
Rarely as the whole plan, and rarely not at all. The structure that makes sense follows from matching the certainty of income to the necessity of the expense.
Cover the floor. Work out the essential expenses that must be paid regardless of markets — food, utilities, rent or maintenance, medicines, insurance premiums. Fund that floor with guaranteed lifetime income. Fund everything above it from the corpus.
What this buys is specific and valuable: a bad market can reduce your holidays and cannot threaten your groceries. It also removes most of the pressure that causes panicked decisions during a downturn, because the part of the plan that must not fail is not exposed to it.
And it directly addresses sequence risk — the annuity income continues through a drawdown, so fewer units have to be sold when prices are low.
Two refinements. Buy later rather than earlier where you can: payouts rise with age at purchase, because the insurer expects to pay for fewer years, so deferring purchases more income per rupee. And ladder the purchase across a few years to avoid fixing the whole thing at one rate.
Judging one properly
Since the return framing is wrong, what should you compare?
- Income per rupee of purchase price, for the same option and the same age, across insurers. This is the only directly comparable number and it varies meaningfully.
- The same option. A quote for a life annuity and one with return of purchase price are not comparable, and the second will always look worse on income.
- Against the alternative — what could you sustainably withdraw from the same sum yourself over an unknown lifespan? Not what it might return.
- The insurer's ability to pay for thirty years, not the current rate.
- Tax treatment, which is material to the net income and is statutory — verify the current position rather than assuming.
One trap worth naming: an annuity's income is often quoted as a percentage, which invites comparison with a deposit rate. They are not the same kind of number. A deposit returns your capital at the end; an annuity's payment includes a return of your own capital throughout. A 7% annuity payout and a 7% deposit are entirely different propositions.
Sizing the floor
The decision reduces to one figure: the essential annual expense that must be funded regardless of markets. Everything else follows from it.
That number comes from the same exercise as an emergency fund — the non-negotiable monthly floor, inflated to your retirement date. For the portion above the floor, FNOTrader's Mutual Funds app computes rolling returns and drawdown across the full AMFI NAV history — around 34 million NAV rows — so the discretionary layer can be tested against the worst window rather than the average.
FNOTrader does not sell insurance or annuities, is not a SEBI-registered investment adviser, and does not recommend products.
Common questions
What is an annuity?
A contract where you hand an insurer a lump sum and it pays you a stated amount for the rest of your life. Under a plain lifetime annuity the capital is generally gone — that is the price of the guarantee, and the guarantee is the product.
Why do annuities have such poor returns?
Because return is not what you are buying. An annuity is the only ordinary instrument that pays for as long as you live, so the right comparison is against what you could safely withdraw from a corpus that must last an unknown time — not against a market return.
What are mortality credits?
The transfer that makes annuities work. An insurer pools thousands of similar buyers; the capital of those who die early funds payments to those who live long. That is real money with no equivalent in a portfolio you manage alone, where you must personally provide for living to ninety-five.
Should I choose return of purchase price?
It is the most popular option in India and the one that most undermines the point — returning capital to heirs means the insurer cannot use it to fund payments, so income drops sharply. If leaving money behind is the goal, term insurance does it far more efficiently.
What is the biggest weakness of an annuity?
Inflation. A level annuity pays the same rupees for decades, and at 6% inflation purchasing power roughly halves every twelve years — an income comfortable at sixty may be inadequate at eighty. That is the strongest argument against annuitising an entire corpus.
How are annuities best used?
To cover the floor. Fund essential expenses that must be paid regardless of markets with guaranteed lifetime income, and everything above that from the corpus. A bad market then reduces holidays rather than threatening groceries.
Should I buy an annuity early or late?
Later, where you can. Payouts rise with age at purchase because the insurer expects to pay for fewer years, so deferring buys more income per rupee. Laddering the purchase across a few years also avoids fixing the whole amount at one rate.
How do I compare annuity quotes?
On income per rupee of purchase price, for the same option and the same age. A life annuity and one with return of purchase price are not comparable. And an annuity payout quoted as a percentage is not the same kind of number as a deposit rate, since it includes a return of your own capital.
