Inflation is the general rise in prices over time. It affects daily student costs, the value of cash and the meaning of an investment return.
What the sources confirm
Stats SA identifies CPI as South Africa’s official measure of consumer inflation.[1]
Stats SA reported annual consumer inflation of 5.0% in June 2026, up from 4.5% in May 2026.[2]
The SARB’s May 2026 statement discussed energy, food and services pressures and a 3% inflation target.[3]
Inflation changes purchasing power
If prices rise while your money remains unchanged, the same amount buys less. A balance can stay numerically stable while losing economic value.
This matters for goals several years away. Future tuition, rent, transport and food may cost more than today’s estimate.
Your personal inflation may be different
Official inflation measures a broad basket of goods and services. A student’s personal budget may be more exposed to food, transport, accommodation and data.
If those categories rise faster than the overall measure, the student may experience stronger financial pressure than the headline number suggests.
Nominal return versus real return
A nominal return is the percentage shown before considering inflation. A real return reflects the change in purchasing power.
An investment that grows while prices also rise has improved purchasing power by less than the headline return suggests.
Cash still has a role
Inflation does not mean all cash is bad. Cash is useful for emergencies and short-term goals because it is accessible and generally less volatile.
The mistake is using one type of asset for every goal. Short-term stability and long-term growth serve different purposes.
Adjust goals and contributions
A long-term savings target should be reviewed as prices change. Contributions may need to rise over time to preserve the original goal.
Salary increases should not automatically become lifestyle increases. Directing part of each increase toward long-term goals can help contributions keep pace.
Inflation and investment risk
Assets with greater growth potential often fluctuate more. The answer is not simply to select the highest historical return. Investors must balance inflation risk with market risk, time horizon and financial capacity.
Frequently asked questions
Does inflation mean cash is useless?
No. Cash remains important for emergencies and short-term goals, where access and stability matter.
Is my salary increase a real increase?
Only if it exceeds the increase in the costs relevant to you, after tax and other deductions.
Should I use the latest monthly inflation rate for a 20-year plan?
Not by itself. Use a range and review it over time.
Education, healthcare, rent and food may follow different price patterns. Use a reasonable range and review the estimate annually.
Avoid using one inflation rate for every goal
Track the price of the ten items that dominate your budget—such as residence, transport, food and data. This does not replace official CPI, but it shows why your lived cost pressure can differ from the national average.
Build personal category inflation
A simple approximation subtracts inflation from the nominal return. A more precise calculation divides one plus the nominal return by one plus inflation, then subtracts one. The difference becomes more important when rates are high.
Calculate a real return approximately
A postgraduate goal five years away
Neo estimates that postgraduate study will cost R80,000 in today’s money. If the cost rises over five years, saving exactly R80,000 may leave a shortfall.
He uses an inflation calculator to create a future-cost estimate, then reviews the goal annually instead of treating the first number as permanent.
Your next five actions
- List the costs most important to your personal budget.
- Use the inflation calculator for a future goal.
- Compare nominal and inflation-adjusted results.
- Increase contributions when income rises.
- Keep short-term cash needs separate from long-term growth goals.
