I want to tell you about two people I'll call Thembi and Reza. I've changed the names but the numbers are real, drawn from the kind of conversations I have with clients every week.
In 2016, both earned R25,000 a month. Both were renting, both driving modest cars, both putting away about R2,000 a month into savings. They were in the same place financially.
By 2026, both earned R55,000 a month. That's a meaningful increase, more than double in a decade, which is roughly in line with promotions and career growth for South Africans in professional roles.
Here's where the story diverges.
Thembi's savings rate grew with her salary. Today she's saving R11,000 a month, 20% of her gross income, just as she did when she earned less. She drives a reliable second-hand car, lives in a home she can comfortably afford, and takes one good holiday a year. Her retirement fund and TFSA are on track.
Reza earns the same salary. But today he saves R2,500 a month, the same nominal rand amount he was saving ten years ago. His expenses have grown almost exactly in line with his income. Nicer car. Bigger apartment. Better restaurants. A holiday upgrade or two. Nothing dramatic. Just a gradual drift upward, month by month, year by year.
Reza isn't reckless. He isn't irresponsible. He hasn't made any single bad decision. But a decade of lifestyle inflation has quietly cost him a fortune.
What lifestyle inflation actually is
Lifestyle inflation, sometimes called lifestyle creep, is the tendency for spending to increase as income increases. It's not a dramatic event. There's no moment where you consciously decide to blow your salary. It happens one reasonable decision at a time.
You get a raise. The R8,000-per-month apartment you're renting feels a bit small now, so you upgrade to R12,000. It's still affordable on your new salary, and it's a nice place. Then you replace the car. Then you start spending a bit more on food, eating out more, buying better groceries, ordering in on weeknights because it's been a long week. Each decision, on its own, is entirely defensible.
The problem is the aggregate. And the compounding effect of all those decisions over time.
The real cost, with numbers
Let's go back to Thembi and Reza, and run the numbers forward to retirement.
Both are 35 today and plan to retire at 65. Both invest at an average return of 10% per annum, a reasonable long-term assumption for a diversified equity portfolio in South Africa.
Thembi saves R11,000 per month today and increases her contributions by 5.5% every year alongside her expected salary growth. By 65, she will have accumulated approximately R74 million.
Reza saves R2,500 per month and, because his spending always expands to fill his income, never manages to meaningfully grow that number. By 65, he will have accumulated approximately R5.6 million.
Same salary. Same career trajectory. Same investment returns. A difference of R68 million at retirement, driven entirely by what they chose to do with the money that was left over after spending.
Reza isn't retiring in poverty. R5.6 million is not nothing. But it will generate roughly R23,000 per month in retirement income at a 5% drawdown rate. That's less than half his current salary. And given that he's been living on R55,000 a month, it's going to feel like a significant step down.
Thembi, with R74 million, can draw R308,000 a month. She's not working in retirement unless she wants to.
Why it happens, the psychology
Lifestyle inflation persists because of two powerful and well-documented psychological forces: hedonic adaptation and social comparison.
Hedonic adaptation means that we quickly get used to improvements in our circumstances. The upgrade that excited you becomes the new baseline within months. The new car stops feeling new. The bigger apartment becomes just "home." You've adapted, so the pleasure that justified the upgrade fades, and you need another upgrade to get that feeling back.
Social comparison means we gauge our financial situation relative to the people around us. As your peer group earns more, they buy bigger homes and take more expensive holidays, and you feel a quiet pressure (often unconscious) to keep up. This isn't vanity. It's deeply wired human behaviour. But in a world of Instagram and LinkedIn, the reference group for comparison has never been more visible or more aspirational.
Neither of these forces will ever go away. Which means the antidote can't be willpower. It has to be structure.
How to protect yourself from it
1. Pay yourself first, automatically
The most reliable defence against lifestyle inflation is to make your savings decision before your spending decision. Set up a debit order that moves money into your RA, TFSA, and investment accounts on the day your salary lands. What's left is yours to spend freely. You cannot lifestyle-inflate money you never see.
This is not a new idea. It's been called "pay yourself first" in personal finance for decades. But most South Africans still do it the other way around: they spend what they spend, and save what's left. What's left is usually very little.
2. Tie savings increases to salary increases
Every time you get a raise, increase your debit order. Not all of it, give yourself something to enjoy. But a rule like "50% of every raise goes to savings, 50% is mine to spend" ensures that your financial position improves alongside your lifestyle, rather than being crowded out by it.
If you get a R5,000 monthly increase, commit R2,500 to savings before you adjust any spending. You'll still enjoy the raise. But you won't wake up at 60 wondering where it all went.
3. Make the big three decisions carefully
Lifestyle inflation is not driven by coffee and eating out, regardless of what personal finance clickbait will tell you. It's driven by three major categories: housing, vehicles, and debt payments.
These are the decisions that lock in your fixed monthly expenses for years at a time. An upgraded apartment adds R4,000 per month to your fixed costs indefinitely. A vehicle finance agreement locks in R8,000 a month for 72 months. These are the choices that really determine whether your savings can grow.
The rule I use with clients: housing costs (rent or bond repayment) should ideally stay below 30% of gross income, and total fixed monthly commitments (housing, vehicle, debt repayments) below 50%. If you're above these thresholds, lifestyle inflation has already taken hold, and the corrective action is bigger than cutting a subscription.
4. Know your savings rate, not just your savings amount
Reza's mistake wasn't that he saved R2,500. Ten years ago, R2,500 was 10% of his income, which is reasonable as a starting point. The mistake was that as his salary grew, the percentage shrank. Today R2,500 is less than 5% of his gross salary.
Track your savings as a percentage of income, not as a rand amount. If your percentage is falling while your salary is rising, you're lifestyle inflating, even if the rand amount you're saving is going up slightly.
A target savings rate of 15–20% of gross income is the standard benchmark used by most financial planners for someone who starts saving in their mid-twenties. If you're starting later, you'll need a higher rate. If you've been lifestyle inflating for a decade, you'll need a plan.
If you recognise yourself in Reza
Most people who read this article will. Lifestyle inflation is the norm, not the exception. If you've been earning a good income for five or ten years and you don't have much to show for it, this is almost certainly why.
The good news is that it's fixable. The corrective actions are not dramatic. You don't need to sell your car or move to a smaller apartment (though for some people that's the right call). You need to do two things:
First: calculate your actual savings rate right now. Total monthly savings (RA contributions, TFSA contributions, unit trust debit orders, any investment savings) divided by gross monthly income. If it's below 10%, you have work to do.
Second: set up automatic increases. Start with whatever you can, even R500 extra per month, and build a commitment that the next raise goes 50% into savings. Do this once, automate it, and don't touch it.
The maths of compounding is extraordinarily forgiving if you give it time. But it requires a savings rate that keeps pace with your income. That's the one discipline that separates the Thembis from the Rezas, not income, not intelligence, not luck.
What to do right now
If you'd like a clear, structured way to audit your current financial position, including your savings rate, your fixed-cost ratio, and your retirement trajectory, the Budget Planner on the products page walks you through exactly this. It's designed for South African households and gives you a clear picture of where your money is going and what needs to change.
If you'd rather talk it through, book a free 30-minute call. In 30 minutes we can usually identify exactly where lifestyle inflation has crept in, and what a realistic corrective plan looks like for your specific situation.
The earlier you address it, the less it costs you. And for most South Africans, addressing it at 35 or 40 still leaves more than enough time to build real wealth.
