As South Africans continue to navigate a difficult economic climate marked by rising living costs, fuel price pressure, unreliable electricity supply and growing financial stress, many consumers may be unknowingly further sabotaging their own savings goals through small, seemingly harmless spending habits.

According to Sean van Zyl, Certified Financial Planner® at Old Mutual Personal Finance, these “silent spending behaviours” often go unnoticed because they are embedded in daily routines, emotional coping mechanisms and social expectations. “Yet over time, they can significantly weaken long-term financial resilience and savings potential”.

Van Zyl says consumers often focus on major expenses when reviewing their finances or even budgeting, while overlooking the repeated smaller purchases that gradually chip away at disposable income.  “Many people do not realise how much money quietly leaves their accounts through convenience spending and emotionally driven purchases. Individually, these expenses may appear insignificant, but collectively and consistently over time, they can derail savings plans and create financial pressure,” he says.

Below are some of the top silent spending behaviours that van Zyl says, if left unchecked, can seriously undermine one’s savings objectives.

1. The takeaway culture

According to van Zyl, one of the most common silent spending habits is convenience spending, particularly fast foods and takeaways purchased in addition to monthly grocery budgets. He notes that while many households carefully budget for groceries, very few consumers actively allocate a separate budget for convenience meals or spontaneous food purchases.

This is becoming particularly prevalent as ongoing electricity disruptions and power outages continue to affect households across the country as this makes it difficult for many families to prepare meals at home consistently.

He adds that “when people are tired, stressed or unable to cook because of disruptions at home, convenience spending becomes an easy solution. The challenge is that these purchases often happen outside the formal budget, which makes them difficult to track”.

2. The danger of “micro-purchases”

Another major contributor is what van Zyl describes as “micro-spending”, the frequent, low-value purchases consumers make almost automatically throughout the month.  These include convenience store snacks while filling up fuel, impulse grocery add-ons, unplanned coffees, or regularly purchasing airtime and data for family members and loved ones. Giving money to friends and family when unbudgeted will also cripple you, so budget giving. Giving should only come from excess or sacrifice.

While each purchase may feel minor in isolation, the cumulative effect can be substantial. The opposite can be seen in compounded investment growth. It is like planting a seed, it may take months or years to show anything, and when you least expect it, a full-grown plant or tree will be there.

“Consumers often underestimate how much these small transactions add up over time because they are emotionally rationalised as necessary, affordable or too insignificant to matter,” says van Zyl.

3. The FOMO on entertainment

Entertainment and social spending also quietly consume savings capacity, particularly when driven by social pressure or the desire to maintain relationships and a sense of belonging.  Whether it is after-work drinks, unplanned dinners, weekend outings or hosting visiting family and friends, these social expenses are frequently not budgeted for in advance.

“People naturally do not want to feel excluded, especially in professional or social environments. There is often pressure to participate, even when the expense was never part of the monthly financial plan,” he explains.

Van Zyl says that consumers should be especially cautious of spending patterns linked to emotional decision-making rather than deliberate financial planning.

4. The psychological pull of retail “specials”

Retail promotions and specials are another silent threat to saving, particularly when consumers mistake “specials” for things they need.

Van Zyl says many people purchase items, like shoes or handbags, simply because they are advertised as specials, even when the purchase was not planned or budgeted for or even needed.  “The word ‘special’ creates a psychological trigger. Consumers often feel they are saving money by buying discounted items, even if the purchase itself was unnecessary at that particular time,” he says.

At the heart of many of these behaviours is emotional spending driven by stress, anxiety and the human need for comfort and reward.

“People are living under immense pressure. Work stress, financial stress and broader economic uncertainty all affect emotional wellbeing. Spending can temporarily create a sense of deceptive comfort, relief or even a sense of control,” he says.

With that said, it is important to spoil yourself as a reward, but this should be planned. Give yourself pocket money to spend as you wish. This should be planned and intentionally give yourself an amount to spend without guilt.  However, van Zyl warns that these behaviours become problematic when they begin replacing intentional financial planning and disciplined saving.

One of the clearest indicators, van Zyl says, that silent spending habits may be becoming financially harmful is when consumers start relying on credit to sustain their lifestyle.  He says addressing the issue requires more than simply cutting expenses. “It is important to understand why you are spending. Is it stress? Is it social pressure? Is it the desire to maintain a certain lifestyle? Financial behaviour is deeply connected to psychology”.

Van Zyl, therefore, encourages consumers to seek both psychological and financial support where necessary, adding that sustainable financial improvement requires honesty, consistency and realistic expectations.

“Nevertheless, there is no silver bullet and no one-size-fits-all solution. Every person’s financial situation, goals and pressures are different. The important thing is to start recognising the patterns, make intentional adjustments and seek appropriate guidance,” he says.

He adds that meaningful financial progress often requires sacrifices and behavioural changes that may take time to develop.

“Good financial habits are built consistently over time. Consumers should not think in terms of perfection or all-or-nothing solutions. Small, intentional improvements can make a significant difference in the long term,” he says. Remember there is no quick fix, it is a lifelong journey and not a destination.
