It's the question almost everyone avoids until it feels uncomfortably late: how much money do I actually need to retire? The honest answer is that it depends on your life - but that's not an excuse to never work it out. With a few simple principles, you can get a realistic sense of the target, where you stand, and what to do about it. And the single most important factor is something you can act on today: time.
This guide walks through how to think about your retirement number, a rough way to estimate it, why starting early matters so much, and how to tell if you're on track. No complex formulas, just a clear way to get your head around it.
Why there's no single magic number
You'll sometimes see headlines claiming you need a specific amount to retire. Treat these sceptically - the real figure depends entirely on *your* circumstances:
- *Your lifestyle.* Someone who wants to travel and eat out needs more than someone content with a quiet, simple life.
- *Your expenses in retirement.* Will your home be paid off? Do you support dependants? What are your medical costs likely to be?
- *When you retire and how long you live.* Retiring earlier, or living longer, means your money has to stretch further.
- *Inflation.* Prices rise over time, so the income you need will keep growing throughout retirement.
So instead of chasing one universal number, the useful exercise is to estimate *your own* based on the income you'll want in retirement. That's far more meaningful than any general figure.
Start with the income you'll need
Retirement isn't really about a lump sum - it's about having enough *income* to live on once your salary stops. So the starting question is: how much money per month will I need to live comfortably in retirement?
A common rule of thumb is that you'll need roughly *70% to 80% of your pre-retirement income* to maintain your lifestyle, since some costs fall away in retirement (you're no longer saving for retirement, the home may be paid off, work-related costs disappear). But this is only a guide - your real number depends on your situation. Someone with a bond paid off and simple tastes might need less; someone wanting an active, travel-filled retirement might need more.
The practical step: estimate your likely *monthly expenses in retirement* in today's money. That figure is the foundation for everything else.
A rough way to estimate the lump sum
Once you know the annual income you'll want, you can get a rough sense of the lump sum needed to provide it. A widely used (if simplified) approach is the idea that you can sustainably draw around *4% to 5% of your savings each year* in retirement without running out too quickly.
Working backwards: if you want, say, R20,000 a month - R240,000 a year - and you assume a roughly 4-5% sustainable drawdown, you'd need somewhere in the region of *R5 million to R6 million* saved by retirement to provide that income (R240,000 divided by 4% is R6 million; divided by 5% is R4.8 million).
A few honest caveats: this is a *rough rule of thumb*, not a precise calculation. It ignores the detail of inflation, investment returns, how long you live, tax, and the type of annuity you choose. The numbers can look intimidating, and they're sensitive to your assumptions. But the exercise is still useful: it turns a vague worry into a ballpark target you can actually plan towards, and it shows why retirement saving needs to start seriously and early.
Why starting early matters more than anything
Here's the part that genuinely changes outcomes: *time is the most powerful factor in retirement saving*, far more than how much you earn.
This is because of *compound growth* - your investment returns earn returns of their own, and over decades that snowballs dramatically. Money invested in your 20s has 30 or 40 years to compound; money invested in your 50s has very little time to grow. The result is that someone who starts saving modest amounts early often ends up with more than someone who starts saving large amounts late.
A simple illustration: contributing a steady amount from age 25 can comfortably outgrow contributing the same amount from age 40, even though the early starter put in money for fewer rands per month in some cases - the extra years of compounding do the heavy lifting. Every year you delay makes the target harder to reach and the required monthly contribution larger.
The lesson is blunt: the best time to start saving for retirement was years ago; the second-best time is now. Even small contributions started today beat waiting until you can afford "enough".
How to tell if you're on track
You don't need a financial degree to sanity-check your progress. A few approaches:
- *Use your fund's tools.* Most retirement funds and providers offer online calculators where you enter your age, savings and contributions and get an estimate of your projected retirement income. These give a useful reality check.
- *Look at your replacement ratio.* This is the percentage of your final salary your savings are projected to replace as income. If you're heading well below the 70-80% guideline, that's a signal to save more.
- *Watch the warning signs.* Common red flags: not contributing at all, cashing out retirement savings when changing jobs (a major destroyer of retirement outcomes - see our dedicated article), starting late, or contributing only a small percentage of income.
If a check suggests you're behind, the response isn't despair - it's to increase contributions, preserve what you have when changing jobs, and let time do as much work as possible.
What to do if you're behind
Many people realise late that they haven't saved enough. It's not hopeless, but it does require action:
- *Increase your contributions* as much as you can, and raise them whenever your income grows.
- *Don't cash out* retirement savings when you change jobs - preserve them (covered in our article on preserving savings).
- *Use tax-advantaged tools* like a retirement annuity to save more efficiently, and a TFSA for additional tax-free growth.
- *Consider working a little longer* if feasible - even a few extra years of contributing and growth, while drawing nothing, makes a meaningful difference.
- *Keep fees low and stay invested* appropriately for growth, especially while you still have time.
The earlier you confront the gap, the more options you have.
Key takeaways
- There's *no single magic number* - your retirement target depends on your lifestyle, expenses, and how long your money must last.
- Start by estimating the *monthly income you'll need in retirement, often guided by 70-80% of pre-retirement income*.
- A rough rule is that you can draw around *4-5% of your savings a year*, which suggests sizeable lump sums - useful as a ballpark, not a precise figure.
- *Starting early is the most powerful factor*, thanks to compound growth - small amounts saved young often beat large amounts saved late.
- Check your progress with your fund's calculators, and if you're behind, *increase contributions, preserve your savings, and use tax-advantaged tools*.
Your next step
Work out a rough estimate of the monthly income you'll want in retirement, then use your retirement fund's online calculator to see your projected income against it. If there's a gap - and for most people there is - increase your contributions starting with your next payslip, even slightly. Then commit to never cashing out retirement savings when you change jobs. Our articles on RAs and preserving your savings explain how.
