10 ways South Africans quietly blow up their retirement and don’t see it coming

The biggest threats to retirement are often small behavioural mistakes that build up over time. Here are 10 retirement mistakes that can derail even a well-prepared retirement.

Retirement rarely falls apart because of one dramatic financial mistake.  More often, it happens slowly. Small decisions that seem reasonable at the time compound over years until people find themselves in a position they never expected.

After years of helping South Africans prepare for retirement, I have seen that the biggest threats are often not investment markets or economic uncertainty. They are behavioural mistakes – decisions people make because they feel natural after decades of working and saving.

Here are 10 retirement mistakes that can quietly derail even a well-funded retirement.

1. Failing to switch from building wealth to spending wisely

For most of our working lives, the goal is accumulation. We buy homes, build businesses, save for retirement and provide for our families.  Retirement requires a completely different mindset.

The skill that helped you build wealth – accumulating assets – now needs to be replaced by the ability to spend sustainably.

This transition is surprisingly difficult. The 10X Investments Retirement Reality Report has highlighted how many South Africans struggle with preserving retirement savings, with a significant number choosing to cash out retirement savings when changing jobs.

The challenge is that the habit of spending what is available can continue into retirement, when every decision has a long-term impact.

2. Allowing emergencies to become expensive debt

Many retirees have investments, but not enough accessible cash reserves. Then life happens. A vehicle repair, medical expense or unexpected home maintenance issue arrives, and the easiest solution becomes using a credit card.

The problem is that high-interest debt can quickly destroy retirement income.

A proper retirement plan should include an emergency fund that is easily accessible – not invested for maximum growth, but available when life does not go according to plan.

3. Not having the retirement conversation with your partner

One of the biggest retirement risks has nothing to do with money. It is retiring with completely different expectations.

One spouse may dream of travelling, while the other wants a quieter lifestyle close to family. One may want to relocate, while the other wants to remain where they are.

These conversations often happen too late. Retirement is not only a financial transition. It is a lifestyle transition, and couples need to plan for both.

4. Retiring without a spending strategy

Many people approach retirement with one question: “How much money do I need?” But a retirement number without a spending plan is incomplete.

Markets move in cycles. A retiree drawing the same income regardless of investment performance can put unnecessary pressure on their portfolio.

This is why retirement income strategies increasingly focus on guardrails – adjusting spending within reasonable limits depending on market conditions rather than following a rigid approach.

5. Underestimating healthcare costs

Many retirees assume their medical aid will cover everything. Unfortunately, healthcare costs can create significant financial pressure.

Specialists often charge more than medical schemes reimburse, leaving patients with unexpected shortfalls. Gap cover can help protect against these gaps, while dread disease cover can provide valuable financial support if a serious illness occurs.

Healthcare planning should form part of retirement planning – not be treated as an afterthought.

6. Waiting too long to get advice

Retirement planning involves complex decisions around investments, tax, estate planning and income strategies. Many mistakes are difficult to fix after retirement.

Getting advice before making major decisions can provide valuable perspective and prevent costly errors. A qualified professional can also help retirees avoid emotional decisions during uncertain markets.

7. Financing adult children indefinitely

Helping children is part of being a parent. However, retirement savings are designed to support one household – not indefinitely finance multiple generations.

Many retirees continue paying for adult children’s expenses, vehicles, subscriptions or lifestyle costs without considering the impact on their own financial independence.

Supporting children is admirable, but it should not come at the expense of your own retirement security.

8. Falling for investment scams

Some of the most damaging financial losses do not happen because people are careless. They happen because trustworthy people are persuaded by opportunities that appear legitimate.

Many failed investments look professional. They have marketing material, offices and convincing stories.

The lesson is simple: trust is not a substitute for due diligence. Any investment opportunity should be properly researched, understood and independently reviewed.

9. Ignoring tax planning

Tax is one of the biggest lifetime costs investors face, yet many retirees only think about it when submitting their tax returns.

The decisions around which investments to draw from, how to structure retirement income and how to use available tax allowances can significantly influence how much money remains available throughout retirement.

Tax planning is not a once-off event. It should be reviewed every year.

10. Retiring from something instead of retiring to something

Perhaps the most overlooked retirement risk is losing purpose. Many people spend decades working towards retirement but never consider what retirement will actually look like.

A successful retirement is not simply the absence of work. It is having something meaningful to move towards. That could be spending more time with family, starting a new venture, volunteering, travelling or pursuing a passion.

The financial plan is only one half of retirement. The other half is creating a life you are excited to live. Retirement success is not about avoiding every mistake. It is about recognising the risks early enough to make better decisions.

A good retirement plan does not predict the future perfectly. It creates clarity, confidence and the ability to adapt when life changes.
