The Buffalo Effect: How R100 a Month Could Grow Beyond R200,000
The combination of consistency and compound growth could turn a modest saving habit into more than R200,000.
Most South Africans know the R100 note by the animal printed on it: the Cape buffalo. Some still call it a “clipper”, a nickname said to date back to the days when ten R10 notes were held together with a paper clip.
Whatever you call it, R100 does not travel particularly far these days. It can disappear into a takeaway meal, a few coffees or an unplanned stop at the shops with alarming efficiency.
That is precisely why it makes such a useful starting point for a conversation about saving. R100 feels small enough to spend without much thought—but, invested consistently over a long period, it can begin building a financial herd of its own.

What Could R100 a Month Become?
According to Brett Caminsky, Director at Atlas Finance, the buffalo offers a simple analogy for the power of regular saving.
“On its own, a buffalo doesn’t look particularly remarkable. But over time, buffalo build herds. Their strength comes from steady growth, not overnight transformation. Saving works in much the same way,” he says.
The important distinction is that one R100 note will not magically become R200,000. The calculation assumes that R100 is invested every month, earns an average annual return of 10% and remains invested so that its returns can compound.
Under those assumptions, the figures look like this:
Investment period | Your contributions | Illustrative value |
5 years | R6,000 | Approximately R7,700 |
10 years | R12,000 | Approximately R20,500 |
20 years | R24,000 | Approximately R76,000 |
30 years | R36,000 | Approximately R226,000 |
After 30 years, the investor would have contributed R36,000. The remaining growth would come from the assumed investment returns and the effect of compounding.
These figures are illustrative, not guaranteed. They are also calculated before fees, tax and inflation, all of which could substantially reduce the investment’s eventual value and spending power.

How Compound Growth Builds the Herd
Compound growth occurs when an investment begins earning returns not only on the money contributed, but also on the returns it has already generated. In simple terms, the money earns money—and that new money is then given an opportunity to do the same.
The early years can feel painfully uneventful. After five years, the difference between the R6,000 contributed and the projected R7,700 value is hardly the sort of result that inspires dramatic music and champagne.
The real acceleration comes later. Time allows each new return to join the investment base from which future returns may be earned. The longer the money remains invested, the greater the opportunity for that compounding effect to develop. This is why starting early can sometimes matter more than beginning with a large contribution. The basic mechanics of compound interest are explained by the US Securities and Exchange Commission’s investor education resource.
Why Small Savings Still Matter
South Africans are frequently told to save more, often by people who appear blissfully unaware of the cost of groceries, transport, electricity and simply keeping a household upright.
For many families, saving thousands of rand every month is not realistic. That does not mean smaller amounts are pointless.
A modest contribution can help establish the behaviour behind long-term wealth: putting money aside regularly, leaving it invested and increasing the contribution when circumstances allow. R100 may be the starting point, rather than the permanent limit.
“The biggest barrier isn’t usually income; it’s believing that small amounts don’t matter,” says Caminsky.
Income certainly affects how much someone can save, and many households genuinely have little or nothing left after essential expenses. However, for those who can free up even a small amount, consistency may be more useful than waiting for the mythical month when there is suddenly plenty of spare money.
Start Small, Then Grow the Contribution
The buffalo calculation becomes more powerful when the monthly contribution increases over time.
An investor might begin with R100, move to R150 after a salary increase and gradually raise the amount whenever debt is settled or household cash flow improves. The habit is established first; the contribution grows as life allows.
Before investing, it may also be sensible to address expensive short-term debt and build an accessible emergency fund. An investment intended for 20 or 30 years should not become the first place you turn when the geyser bursts or the car decides to develop a costly personality.
Anyone choosing an investment should consider its fees, tax treatment, risk level and accessibility. A registered financial adviser can help match an investment strategy to a person’s circumstances and goals.

Do not dismiss an amount simply because it seems too small to change your life today. Begin with something affordable, automate the monthly contribution and review it once a year. The lesson of the buffalo is not that R100 guarantees riches. It is that patient, repeated action can become far more powerful than its humble beginning suggests.
