Running out of money is one of the biggest fears people carry into retirement. Once a regular paycheck stops, you have to turn a lump sum of savings into an income that can last for the rest of your life, however long that turns out to be. Annuities are one of the oldest and most widely used tools for solving that problem, because they can convert savings into a predictable stream of payments that you cannot outlive.
But annuities are also among the most debated financial products. Supporters see them as insurance against a long life and volatile markets, while critics point to high costs, complexity, and a loss of flexibility. The truth is that an annuity can be a smart choice for some people and a poor fit for others. This guide explains how annuities work, the main types available, and the pros and cons, with a look at how the rules differ across the US, UK, Canada, and Australia.
What Is an Annuity?
An annuity is a contract with an insurance company. In its simplest form, you hand over a sum of money and, in return, the insurer promises to pay you an income, either for a fixed number of years or for the rest of your life. Because the payments can be guaranteed to continue for as long as you live, annuities are essentially a form of insurance against outliving your savings, sometimes called longevity risk.
Insurers can make these promises by pooling many customers together. Some annuity holders will die earlier than expected and some later, and the insurer uses actuarial averages, along with the returns it earns on invested premiums, to fund the guaranteed payments. This pooling is what allows an annuity to pay a lifetime income that a person managing money alone would struggle to match with certainty.
The Main Types of Annuities
Product names vary between countries and providers, but most annuities fall into a few broad categories. Many contracts combine features, so it helps to understand the building blocks first.
Immediate (Income) Annuities
An immediate annuity, sometimes called an income annuity or a single-premium immediate annuity, starts paying you an income almost right away, typically within a year of purchase. You exchange a lump sum for a stream of payments. This type is popular with people who are already retired and want to turn savings into a paycheck without delay.
Deferred Annuities
A deferred annuity has two phases. During the accumulation phase, your money grows over a period of years. Later, in the payout phase, the contract converts into an income stream or is withdrawn as a lump sum. Deferred annuities appeal to people who are still working and want to build up value before drawing an income. A specialized version that only begins paying at an advanced age, such as in your 80s, is sometimes used purely as longevity insurance.
Fixed Annuities
A fixed annuity provides payments based on a rate set by the insurer, offering predictability. The income amount is known in advance and does not move with the stock market, which makes this type attractive to people who value certainty over growth potential. The trade-off is that a fixed income may lose purchasing power over time unless you add an inflation-linked option.
Variable and Investment-Linked Annuities
A variable annuity, known as an investment-linked annuity in some markets, ties your value or income to the performance of underlying investment funds. This offers the potential for higher returns and some protection against inflation, but it also introduces market risk, meaning your income can rise or fall. These products often carry additional fees and optional guarantees, sometimes called riders, that add cost in exchange for downside protection.
Pros and Cons of Annuities
Whether an annuity makes sense depends heavily on your circumstances, other income sources, and appetite for risk. The table below summarizes the main advantages and drawbacks.
| Potential Advantages | Potential Drawbacks |
|---|---|
| Guaranteed income that can last for life, reducing the risk of outliving your money | Loss of flexibility once you commit, as many annuities cannot be reversed or cashed in |
| Predictability that makes budgeting easier, especially with fixed types | Costs and fees that can be high, particularly on variable and rider-heavy products |
| Protection from market swings with fixed and guaranteed options | Inflation risk, since a level income buys less over time unless indexed |
| Peace of mind and simpler money management in later life | Limited inheritance, as basic lifetime annuities may leave little for heirs |
| Optional features such as inflation-linking or survivor benefits | Complexity that makes some contracts hard to compare and understand |
How Annuities Work by Country
Annuities exist in many countries, but the tax treatment, retirement systems, and product names differ significantly. Below is a general overview of how they fit into retirement planning in four major English-speaking markets.
United States
In the US, annuities are sold by insurance companies and commonly split into fixed, indexed, and variable types. They are often bought with after-tax savings or held inside tax-advantaged retirement accounts. A key feature is tax-deferred growth, meaning earnings inside the contract are generally not taxed until withdrawn. Withdrawals before a certain age can trigger additional tax penalties, and product rules and consumer protections vary by state.
United Kingdom
Since pension freedoms were introduced, UK retirees with defined contribution pensions are no longer required to buy an annuity. The main choice is between a pension annuity, which converts your pension pot into a guaranteed income for life, and income drawdown, where your pot stays invested and you draw money flexibly. Annuities offer certainty, while drawdown offers flexibility and potential growth but carries the risk of depleting the pot. Many people use a mix of both.
Canada
Canadians often use a life annuity to convert registered savings, such as an RRSP, into guaranteed lifetime income. A common alternative is a Registered Retirement Income Fund (RRIF), which keeps savings invested and requires minimum annual withdrawals that increase with age. A life annuity provides certainty and longevity protection, while a RRIF offers flexibility and control over investments. These sit alongside government programs such as the Canada Pension Plan and Old Age Security.
Australia
In Australia, most retirees draw on their superannuation. A very common option is an account-based pension, where your super stays invested and you draw a regular, flexible income subject to minimum withdrawal rules. Lifetime and fixed-term annuities are also available and can be layered on top for guaranteed income. How retirement income is structured can also affect eligibility for the government Age Pension through means testing.
Tips and Things to Watch
- Check whether the income is level or inflation-linked, as a fixed payment loses value over decades.
- Understand all fees, commissions, and rider charges before you sign, especially on variable products.
- Consider a survivor or joint-life option if you want a spouse or partner to keep receiving income.
- Look at the financial strength of the insurer, since guarantees are only as reliable as the company behind them.
- Confirm what happens to any remaining value on death and whether a guarantee period or death benefit applies.
- Compare quotes from several providers, as rates and features can vary widely for the same money.
- Consider annuitizing only part of your savings so you keep some flexibility and liquidity.
- Factor in your health and family longevity, which affect how much value a lifetime income is likely to deliver.
So, Are Annuities a Smart Way to Fund Retirement?
For the right person, an annuity can be a powerful part of a retirement plan. If you value guaranteed income, worry about outliving your savings, or want to reduce the stress of managing money in later life, the certainty an annuity provides can be worth the trade-offs. Many planners suggest using an annuity to cover essential expenses while keeping other investments for flexibility and growth.
For others, the costs, reduced flexibility, and limited inheritance potential outweigh the benefits, particularly if you already have substantial guaranteed income from state or workplace pensions. As with most financial decisions, the answer depends on your goals, health, other income, and comfort with risk rather than on whether annuities are good or bad in the abstract.
Frequently Asked Questions
Can I lose money with an annuity?
With a fixed annuity, the income is set in advance and does not fall with the markets, though inflation can erode its buying power. With a variable or investment-linked annuity, your value or income can go down if the underlying investments perform poorly, unless you pay for a guarantee. There is also the risk, usually small in well-regulated markets, that the insurer itself could fail.
What happens to my annuity when I die?
It depends on the contract. A basic single-life annuity may stop paying when you die, leaving nothing for heirs. Options such as a joint-life annuity, a guarantee period, or a death benefit can provide continued income to a spouse or a payment to your estate, usually in exchange for a lower starting income.
Is an annuity better than keeping my money invested?
Neither is automatically better. Staying invested, through options like drawdown, a RRIF, or an account-based pension, offers flexibility and growth potential but leaves you exposed to market falls and the risk of running out of money. An annuity trades that flexibility for certainty. Many retirees combine both approaches to balance security and growth.
When is the best time to buy an annuity?
There is no single right age. Annuity income is influenced by your age, prevailing rates, and your health at the time of purchase, and payments are often higher when you buy later in life. Some people ladder their purchases over several years rather than committing all at once, which can spread out timing risk.
