Living annuity vs. guaranteed annuity: which is right for you?

When you retire from a pension fund, provident fund, or retirement annuity in South Africa, in most cases at least two-thirds of that benefit must be used to buy an annuity — a product that turns your accumulated savings into a regular income. You have two fundamentally different options for how that income works: a living annuity or a guaranteed annuity.

Here's what actually separates the two, and how to think about which one fits your situation.

A living annuity keeps your money invested in the market. You choose how much income to draw each year — anywhere between 2.5% and 17.5% of the remaining capital, reviewed annually. Your income isn't fixed; it depends on your chosen drawdown rate and how your underlying investments perform. If your investments do well and you draw conservatively, your capital can last well into your later years and even grow. If markets underperform or you draw too aggressively, your capital can run out.

A guaranteed annuity, also called a life annuity, works the opposite way. You hand your capital to an insurer in exchange for a fixed income for life — either a flat amount or one that escalates at a predetermined rate each year. The insurer carries the investment and longevity risk. Whether you live to 70 or 100, the income keeps arriving. But once you've purchased it, there's generally no flexibility to change it, and if you pass away shortly after purchase, there is often little or nothing left for your beneficiaries unless you specifically built in features such as a guaranteed payment term or spouse's pension.

In short: a living annuity trades certainty for flexibility. A guaranteed annuity trades flexibility for certainty.

With a living annuity, you control:

• Your drawdown rate, within the 2.5%–17.5% band, reviewed once a year
• How the underlying capital is invested — living annuities are not bound by Regulation 28 in the way pre-retirement savings are, so asset-allocation flexibility is much wider
• What happens to any remaining capital when you pass away — it goes to your nominated beneficiaries rather than being absorbed by an insurer

With a guaranteed annuity, you control:

• Very little, by design — that's the trade-off. You typically choose the structure upfront, such as single life versus joint life, flat versus escalating income, and whether there's a guaranteed payment period, and after that, it runs on autopilot for the rest of your life

The flexibility of a living annuity is also its biggest danger. Because you choose your own drawdown rate, it's entirely possible to draw more than your investments can sustainably support — and the damage often isn't visible for years.

Advisers generally recommend keeping drawdown rates well below the regulatory maximum, often in the 4–5% range for a retirement that could realistically last 25–30 years. Retirement can easily last far longer than most people first assume. Drawing at the higher end of the legal range might feel manageable in year one, but it can quietly erode capital to a point where income has to be cut sharply later — often at the exact stage of life when medical and care costs are rising.

Fees matter here too. Because a living annuity stays invested, ongoing platform, investment, and advice fees continue to apply for as long as the annuity exists — and higher total fees directly reduce how much drawdown the capital can sustainably support.

The certainty of a guaranteed annuity comes at a real cost: once you've bought it, you generally can't undo it. If your circumstances change, if inflation runs hotter than the escalation rate you chose, or if you simply want access to a lump sum later, a guaranteed annuity offers no room to adapt.

There's also a timing element worth understanding: guaranteed annuity rates are heavily influenced by long-term bond yields, not by the stock market. That means the income a given amount of capital can buy you varies depending on when you purchase it — buying during a period of relatively higher long-term rates locks in a better starting income than buying during a low-rate environment, all else being equal.

This is not a perfectly symmetrical choice.

You can usually move from a living annuity into a guaranteed annuity later. You generally cannot move from a guaranteed annuity back into a living annuity. That matters, because many retirees assume they are choosing once between two equally reversible options. They are not.

A common misconception is that this is an all-or-nothing decision. In practice, many retirees split their retirement capital between the two — using a guaranteed annuity to cover essential, non-negotiable monthly expenses, and a living annuity for the remainder, to retain flexibility and growth potential. Some providers also offer a blended or composite annuity, which combines both structures within a single product.

This approach can meaningfully reduce the central risk of each option on its own: it limits how exposed you are to running out of capital in a living annuity, while avoiding locking 100% of your savings into a rigid guaranteed structure.

• Do you have other guaranteed income in retirement, such as a pension, rental income, or a spouse's income, that reduces how much certainty you actually need from this decision?
• How comfortable are you monitoring and adjusting your own drawdown rate every year, potentially for decades?
• Does your family have a history of long life expectancy, which would argue for building in more longevity protection?
• Is leaving capital to beneficiaries a priority, or is maximising your own income for life more important?
• What's your realistic risk tolerance if markets underperform for several years in a row after you've already retired?

Neither option is inherently better — they solve for different problems. A living annuity is well suited to those who want flexibility, are comfortable with some investment risk, and want to preserve capital for beneficiaries. A guaranteed annuity suits those who want certainty above all else and are less concerned with leaving money behind. For many people, the right answer isn't purely one or the other, but some deliberate mix of the two, sized to match their actual income needs and risk tolerance.

This is a decision worth working through properly with a full view of your financial position, rather than defaulting to whichever option a product provider happens to push hardest.
