Most retirement plans are built around investment returns, drawdown rates and tax. Few give medical aid the attention it deserves, even though it is often the single expense that grows fastest once your salary has stopped. In the FNB Retirement Insights Survey 2026, 74% of Personal segment retirees said their living costs were higher than they expected, and 46% said their healthcare costs were substantially higher than they expected. This article explains how to keep your cover affordable without leaving yourself exposed.
Why Medical Aid Costs Keep Outrunning Your Income
The Council for Medical Schemes recommended that 2026 increases be limited to 3.3%, but reported industry coverage shows an approved weighted average increase of 8.1%. At the scheme level, Discovery announced 7.2%, Bestmed 6.8%, Medihelp 8.46% and Bonitas 8.8%. Consumer inflation averaged 3.9% over the first seven months of 2026, so contributions are rising at roughly double the rate of everyday prices.
There is no sign of this easing. The Council for Medical Schemes has guided that 2027 increases be anchored at 3.8%, while the Board of Healthcare Funders argues that is unrealistic, pointing to specialist costs rising at 8.61% a year and hospital costs at 8.51%. Those cost figures come from the industry body, which has an interest in the argument, but they match what members see on their annual renewal letters.
The practical point for a retiree is simple. If your pension or living annuity income is rising at 4% to 5% a year while your medical aid rises at 7% to 9%, the gap widens every year. Budget for healthcare as a separate line that grows faster than your other expenses. Our guide to living annuities explains why that matters when you choose a drawdown rate.
The Mistake Not to Make: Letting Your Cover Lapse
When contributions bite, cancelling medical aid can look like a way to save money, particularly if you are healthy. It is the most expensive option available. Under the late joiner rules, anyone aged 35 or older who joins a scheme without continuous prior cover, or who has a break in cover of more than three consecutive months, pays a penalty added to their monthly contribution. As Discovery’s published rules explain, the penalty is based on the number of years you have been uncovered, calculated as your age minus (35 plus your years of prior creditable cover):
- 1 to 4 uncovered years: 5% of your contribution
- 5 to 14 uncovered years: 25%
- 15 to 24 uncovered years: 50%
- 25 or more uncovered years: 75%
Here is how that works. A 60-year-old with no prior cover has 25 uncovered years (60 minus 35), which puts them in the 75% band. A 60-year-old with 20 years of earlier cover and a long break has 5 uncovered years (60 minus 55), which puts them in the 25% band. The waiver that exists for some members applies only to those under 46 with no pre-existing conditions, so it will not help a retiree. Check with your scheme how long a penalty applies, because the document we reviewed does not set an end date.
The rule has a useful flip side: members with unbroken cover since 1 April 2001 are not penalised at any age. If you have kept your cover continuous, protecting that record is worth a great deal.
How to Downgrade Safely
Moving to a cheaper option within the same scheme does not trigger a late joiner penalty. Many schemes allow downgrades during the year; Discovery, for example, allows them at any time, effective from the first day of the next month, although rules vary by scheme and you should confirm yours. Upgrades are different. They are generally restricted to 1 January each year, because schemes want to prevent members from moving up only once they become ill.
That asymmetry matters. A downgrade is easy, but a reversal can mean waiting until January, and in some cases facing new waiting periods. Treat a downgrade as a decision that is hard to undo, much like buying a guaranteed annuity.
If you switch schemes instead, expect waiting periods of up to three months for general benefits and up to twelve months for condition-specific benefits. If you have had at least 24 months of continuous cover and rejoin within 90 days, typically only the three-month general waiting period applies. If you are on a plan with a medical savings account, a positive balance normally moves with you, but an overspent balance must be repaid, and some payouts on exit can be taxable. These switching details come from a broker comparison site, so confirm them with the scheme you are moving to.
Hospital Plans and What Still Protects You
A hospital plan is the usual downgrade destination. It generally covers in-hospital costs and leaves day-to-day expenses such as GP visits, dentistry, optometry and acute medication for you to pay from your own pocket. Gap insurance data reported in 2026 shows members moving toward cheaper core hospital plans as contributions climb, which is understandable but not risk-free.
One important safety net remains whichever option you choose: Prescribed Minimum Benefits (PMBs). Every registered medical scheme must cover a defined set of conditions regardless of option, currently around 271 diagnosis and treatment pairs plus 26 chronic conditions, including diabetes. Emergency conditions are covered too. PMB cover has limits, though:
- You are usually required to use the scheme’s designated service provider (DSP), and using a non-DSP typically means a co-payment, except in emergencies or where no DSP is within reasonable reach
- PMBs cover defined conditions and treatment protocols, not everything you might want or need
- Check the DSP network, chronic medication formulary and any co-payments before you downgrade, rather than after your first claim
Gap Cover: Who Actually Needs It
Gap cover is short-term insurance, not medical scheme cover, and you can only buy it while you belong to a scheme. It pays part or all of the difference between what a specialist charges and what your scheme pays, along with some co-payments and deductibles. It does not cover GP visits, medicines, dentistry or procedures your scheme excludes entirely.
Premiums quoted for 2026 run from about R150 to R300 a month for a single member and R300 to R500 for a family, with waiting periods commonly around three months for general claims and twelve months for pre-existing conditions. Some products restrict new entry at older ages, so deciding in your fifties is cheaper and easier than deciding in your seventies. Notify your gap insurer whenever you change your medical aid option, and stay with the same insurer where you can, since switching providers can mean fresh waiting periods.
Whether you need it depends on one question: what rate does your option pay specialists? If it pays at 100% of scheme tariff, as many entry and mid-level options do, the shortfall can be large. Members on options that pay 200% to 300% face smaller gaps. One gap provider told the Citizen that large claims which once ran to R6,000 to R12,000 now regularly exceed R50,000. Treat that as indicative, since it comes from an insurer with something to sell, and check your own scheme’s specialist rate before deciding.
The Tax Relief Available After 65
For the 2026/27 tax year, the Medical Scheme Fees Tax Credit is R376 a month for the main member, R376 for the first dependant and R254 for each additional dependant. If you are 65 or older, you also qualify for an Additional Medical Expenses Tax Credit equal to 33.3% of the following: your medical scheme contributions less three times the Medical Scheme Fees Tax Credit, plus your qualifying out-of-pocket medical expenses. Qualifying expenses include professional medical services, hospital and nursing care, prescribed medicines and treatment outside South Africa. Over-the-counter medicines do not qualify unless a practitioner prescribed them.
The practical step is to keep every receipt and scheme statement, and make sure whoever prepares your tax return captures the credit. Confirm how it applies to your household with SARS or a tax practitioner.
Why Your Health Habits Are a Retirement Planning Decision
Everything above is about managing the cost of ill health. The cheaper strategy is needing less of it. Chronic conditions such as diabetes bring years of medication, monitoring and specialist visits, and each one is paid from a finite pool of retirement capital while medical costs inflate faster than your income.
The evidence for prevention is strong. In the Diabetes Prevention Program, a landmark randomised trial funded by the US National Institutes of Health, participants who received a lifestyle programme aiming for 7% weight loss and at least 150 minutes of physical activity a week cut their incidence of type 2 diabetes by 58%. That trial involved people at elevated risk rather than the general population, and results vary between individuals, but the size of the effect shows what is possible.
The World Health Organization’s 2020 guidelines set out a realistic target for adults aged 65 and over:
- 150 to 300 minutes a week of moderate aerobic activity, or 75 to 150 minutes of vigorous activity, or an equivalent combination
- Muscle-strengthening activity involving all major muscle groups on two or more days a week
- Varied balance and strength training on three or more days a week to improve function and prevent falls, a recommendation that now applies to all older adults and not only those with poor mobility
A fall that breaks a hip is a clinical event and a financial one. Strength and balance work in your fifties and sixties is cheap insurance against it. Speak to your doctor before you start a new exercise programme, particularly if you have an existing condition. Also ask your scheme whether it runs a wellness programme and exactly what it rewards, since the value varies widely between schemes.
A Practical Checklist Before You Retire
- Keep your medical aid continuous; never allow a break of more than three months
- Review your option every November, before the January upgrade window closes
- Compare total annual cost, not just the contribution: add expected out-of-pocket spending, co-payments and chronic medication costs
- Check the DSP network and chronic medication formulary before any downgrade
- Find out what rate your option pays specialists, then decide on gap cover, ideally before your sixties
- Keep every medical receipt for the 65+ tax credit
- Budget medical costs as a separate line that grows faster than your general expenses
- Build movement, strength and balance work into your week now, not once something goes wrong
Key Takeaways
- Medical scheme increases have run at roughly double inflation, so healthcare belongs in your retirement budget as its own fast-growing line
- Cancelling cover after 35 risks a late joiner penalty of up to 75% on your contributions, and a break of more than three months can trigger it
- Downgrading within a scheme is usually easy, but upgrading is generally limited to January, so treat a downgrade as hard to reverse
- Prescribed Minimum Benefits give every member a baseline for 271 conditions and 26 chronic diseases, but usually only through designated providers
- Gap cover matters most if your option pays specialists at 100% of scheme tariff; check your own rate before you buy
- Members aged 65 and over can claim an extra medical expenses tax credit, so keep every receipt
- Prevention has a financial return: exercise and weight management lower the risk of chronic conditions that drain retirement capital
Frequently Asked Questions
Should I cancel my medical aid when I retire?
Generally no. If you are 35 or older and your cover lapses for more than three consecutive months, a late joiner penalty of 5% to 75% can be added to your contributions when you rejoin. Downgrading to a cheaper option is usually a safer way to cut costs.
What is a late joiner penalty and how is it calculated?
It is an extra percentage added to your contribution if you join a scheme at 35 or older without continuous prior cover. It is based on uncovered years, calculated as your age minus 35 minus your years of prior creditable cover: 1 to 4 years is 5%, 5 to 14 years is 25%, 15 to 24 years is 50% and 25 or more years is 75%.
Can I move to a cheaper medical aid option mid-year?
Often yes. Downgrades within the same scheme are commonly allowed during the year, though timing varies by scheme. Upgrades are generally limited to 1 January, so check your scheme’s rules and think carefully before moving down.
Do hospital plans cover chronic medication?
Prescribed Minimum Benefits require every scheme to cover 26 chronic conditions regardless of option, including medication, consultations and related tests, usually through designated providers. Conditions outside the PMB list depend on the benefits of your specific option, so check before downgrading.
Do I need gap cover?
It is most valuable if your option pays specialists at 100% of scheme tariff. Premiums quoted for 2026 run from about R150 to R300 a month for a single member, and some insurers limit new cover at older ages, so it is cheaper to decide early. It cannot replace medical aid.
Do I get tax relief on medical aid after 65?
Yes. On top of the standard Medical Scheme Fees Tax Credit, members aged 65 and over can claim an Additional Medical Expenses Tax Credit of 33.3% on qualifying amounts, which includes a portion of contributions and qualifying out-of-pocket expenses. Keep your receipts and confirm the calculation with a tax practitioner.
