── The Most Expensive Sentence in Investing ──
'I've left it too late.' Four words. Six syllables. And I've heard them more times than I can count — from readers, from friends, from the bloke at the pub who asked what I do and then immediately looked like I'd told him he'd failed a test he didn't know he was taking. I've left it too late. It's such a seductive little sentence. It lets you off the hook. It gives you permission to do nothing. It transforms procrastination into something that sounds almost wise — 'I'm not avoiding it, I'm just being realistic about my situation.' And it's almost always wrong.
The internet is absolutely lousy with content aimed at 25-year-olds. 'Start investing at 22 and you'll retire at 40!' 'This 27-year-old has £300,000 in his ISA!' 'If you don't open a LISA before you're 40 the government confiscates your birthday' — okay, I made that last one up, but you get the idea. The entire personal finance content industry is built around telling young people to start young. Which is fine. It's good advice. Starting young IS better — the maths is unambiguous on that point. But there's a quiet, unintended side effect: everyone who ISN'T young reads that stuff and feels like they've already lost. Like they walked into the cinema halfway through the film and there's no point watching the rest. Like the ship has sailed, the train has left the station, the compounding horse has bolted — pick your metaphor, they all say the same thing. 'Should have started earlier, mate. Too bad. Enjoy your tin of beans at 75.'
This post is the antidote to that nonsense.
── You're Going to Be 70 Anyway ──
Here's a thought experiment that changed how I think about starting late. You're going to turn 70. (Or 75. Or 80. Pick an age — it's coming regardless.) That birthday is going to arrive whether you open an ISA or not. The candles are getting lit either way. The question isn't 'will I be old one day?' — spoiler: yes, if you're lucky. The question is: do you want to arrive at that birthday with a portfolio, or without one?
Let's say you're 55. You've got 15 years until you're 70. Fifteen years. That's not nothing. That's a general election cycle three times. That's a Premier League team getting promoted, relegated, promoted again, and changing manager seven times. That's enough time for money invested in a broad global ETF to — if history is any rough guide — roughly double, and then keep growing. A £50,000 pot with £300 a month added over 15 years, compounding at a historically-average-but-not-guaranteed rate, could become something in the region of £180,000-£220,000. That's not a yacht. But it's a lot of dinners out you wouldn't have had otherwise. A lot of holidays. A lot of 'I don't need to worry about that bill' moments. A lot of peace of mind.
And if you're 65? Ten years is still ten years. A £30,000 pot with £400 a month for a decade could become £90,000-£110,000. Is that as much as if you'd started at 25? No. But that's not the comparison that matters. The comparison that matters is: £90,000 versus £0. Having something versus having nothing. Options versus no options. 'I started at 65' versus 'I never started at all.' That's the only comparison worth making.
── The Maths at Every Age (No Tears, I Promise) ──
Let's do something I normally avoid — let's look at some numbers. But let's do it in a way that's honest and encouraging rather than depressing. Here's what happens when you invest £300 a month into a broad global ETF, assuming (big caveat, past performance, nobody knows the future, all the warnings apply) an average real return of about 7% a year after inflation:
Start at 25, invest for 40 years until 65: you'd put in £144,000 of your own money. The compounding could grow it to roughly £750,000. Impressive! Good for you, 25-year-old who doesn't exist in real life and definitely isn't reading this blog.
Start at 35, invest for 30 years until 65: you'd put in £108,000. Compounding: roughly £350,000. Less, yes. Still life-changing. Still a deposit on a retirement that doesn't involve counting coppers.
Start at 45, invest for 20 years until 65: you'd put in £72,000. Compounding: roughly £155,000. That's more than double what you put in. That's a new kitchen and a decade of nice holidays. That's the difference between 'I hope the state pension covers the basics' and 'I've got options.'
Start at 55, invest for 10 years until 65: you'd put in £36,000. Compounding: roughly £52,000. Not earth-shattering. But it's £16,000 you didn't have. And you don't have to stop at 65 — keep adding, keep compounding, and by 75 that £300 a month for 20 years could be north of £150,000.
Start at 65, invest for 10 years until 75: you'd put in £36,000. Compounding: roughly £52,000. And here's the beautiful thing about being 65 — you've probably got more disposable income than you did at 35. The mortgage might be gone. The kids might be financially independent (or at least pretending to be). You might be able to put away £500 or £1,000 a month. And at 65, with a SIPP, the government still gives you tax relief on contributions — 20% basic rate, possibly more if you're a higher-rate taxpayer. Free money. From the government. At 65. The taxman doesn't care how old you are.
The pattern is clear: starting earlier is better. Nobody's disputing that, least of all me. But starting later is still good. Starting later is still worth it. Starting later beats the pants off not starting. And the difference between 'I wish I'd started at 25' and 'I'm starting at 55' is the difference between a fantasy you can't change and a future you can. One of those is useful to think about. The other is a guilt trip disguised as maths.
── The Secret Weapon of the Late Starter ──
Here's something the 'start at 25 or you're doomed' brigade never mentions: you probably earn more now than you did at 25. A lot more. At 25 I was earning whatever a 25-year-old earns in their first proper job — which, adjusted for inflation, was approximately 'not very much.' By 45, I was earning considerably more. By 55, more still. Late starters have a secret weapon that early starters don't: a bigger shovel.
The 25-year-old putting away £200 a month is doing brilliantly — but they're probably stretching to hit that number. The 50-year-old who's just finished paying off the mortgage might be able to put away £800 a month without breaking a sweat. The £200-a-month early starter has time on their side. The £800-a-month late starter has firepower. Both paths work. Both paths lead somewhere worth going. The only path that doesn't work is the one where you put away £0 a month for 40 years and then wonder what happened.
There's also the SIPP tax relief angle, which is particularly juicy for late starters in their 50s and 60s. If you're a basic-rate taxpayer, every £80 you put into a SIPP gets topped up to £100 by HMRC. If you're a higher-rate taxpayer, it's even better — you claim back additional relief through your tax return. That's an instant, guaranteed 25% return before your money has even been invested. No ETF can promise that. No stock picker can beat that. The government is literally paying you to save for retirement, and the closer you are to retirement, the more valuable that boost becomes because it has less time to compound — so you need it to work harder, faster. Use it.
── The Psychological Trap of 'It's Too Late' ──
Let's be honest with each other for a moment. When you tell yourself 'I've left it too late' — and I've said this to myself, by the way, I'm not standing on a pedestal here — is it actually true, or is it just a very effective excuse? Because 'it's too late' is the perfect procrastination tactic. It sounds like realism. It dresses itself up as clear-eyed acceptance of one's situation. But underneath, it's often just fear wearing a sensible cardigan.
Fear of looking at the numbers. Fear of admitting you don't know how ISAs work. Fear of clicking the wrong button and accidentally buying 10,000 shares of a Bulgarian mining company. Fear of telling your partner 'I think we should start investing' and then having to explain what an ETF is when you're still not entirely sure yourself. Fear of being bad at it. Fear of losing money. Fear of finding out you've got less than you hoped. These are all completely reasonable fears. Investing IS intimidating when you're new to it. The financial industry has spent decades making it sound complicated because complicated justifies fees. But the fears are not the same thing as 'it's too late.' They're just fears. And fears can be walked through.
The real 'too late' is when you're on your deathbed wishing you'd done something — anything — 20 years earlier. The real 'too late' is the version of you at 75 who looks back at the 55-year-old version and thinks 'why didn't you just open the bloody account?' That's the only 'too late' that actually exists. Everything else is just different degrees of 'still plenty of time.'
── What If I Only Have a Small Amount? ──
Another cousin of 'it's too late' is 'I don't have enough to make it worth starting.' £50 a month. £25 a month. £10 a month. What's the point? The point is the habit. The point is the account being open. The point is the psychological shift from 'someone who doesn't invest' to 'someone who does.' The first £100 is the hardest £100 you'll ever invest — not because of the money, but because of the mental barrier. Once that £100 is in there, £200 feels easier. Once £1,000 is in there, you start checking it (not too often, please — quarterly, remember) and feeling quietly proud. Once £10,000 is in there, you're an investor. You've crossed the Rubicon. You're in the club.
Trading 212 lets you buy fractional shares — you can own 0.01 of a VWRP share for literal pennies. InvestEngine has no minimum. Vanguard's minimum monthly contribution is £100 for most funds, but you can start with a lump sum of £500. Freetrade has a free tier. The barriers to entry have never been lower. The platforms are designed for people exactly like you — people who aren't sure, who are starting small, who want to dip a toe in without committing to a full cannonball. The only remaining barrier is the one in your head.
── But What About... (The Objections Section) ──
'But what if the market crashes the day after I invest?' It might. It's happened to me. Multiple times. It'll happen again. And if history is any guide — which it might not be, but it's all we've got — the market will eventually recover and go on to new highs. The people who lost money in 2008 were the ones who sold. The people who kept buying through 2008 and 2009 are sitting on very nice returns today. The crash isn't the problem. Selling during the crash is the problem.
'But I don't understand any of this stuff.' Neither did I when I started. Neither did anyone. You learn by doing. You open an account. You buy one ETF. You read a bit. You ask questions. You make a few mistakes (everyone does — I've made more than most). And gradually, over months and years, it stops feeling like a foreign language and starts feeling like common sense. You don't need to understand discounted cash flow analysis or Modern Portfolio Theory or the difference between monetary and fiscal policy. You need to understand three things: buy a broad low-cost index fund, do it regularly, don't sell when it drops. That's genuinely most of what you need to know.
'But I'm worried I'll pick the wrong thing.' Then pick the thing that owns everything. VWRP — the Vanguard FTSE All-World ETF — owns 3,700+ companies across nearly 50 countries. You can't 'pick wrong' if you pick everything. Is it the optimal portfolio according to some academic paper? Probably not. Will it serve you perfectly well for the next 20 years? History suggests yes — though nobody can guarantee that, and anyone who does is selling something. The perfect is the enemy of the good, and in investing the good is very good indeed.
── A Little Story About My Friend Dave ──
I've got a friend — let's call him Dave, because his name is Dave and subtlety has never been my strong suit. Dave is 58. For 30 years, Dave has been saying he should 'get around to' investing. For 30 years, Dave has been putting it off. 'I'll do it next year.' 'I'll do it when the markets settle down.' 'I'll do it after I've read that book.' 'I'll do it when I've got more to invest.' Dave is 58 now and he's still saying the same things. Dave has missed 30 years of compounding. Not because he couldn't afford to invest — he could. Not because he didn't know how — he's a smart bloke, he could have figured it out in an afternoon. Because he never started.
Don't be Dave. Dave is lovely. But Dave's financial future is going to be harder than it needed to be because he spent three decades waiting for the perfect moment that never arrived. Meanwhile, another friend — let's call her Sarah — started at 52. She knew she was 'late.' She didn't care. She opened an ISA, set up a £250 monthly direct debit into a global ETF, and got on with her life. She's 63 now. Her portfolio is worth about £42,000 — more than double what she put in. She told me last year it's the best financial decision she ever made. 'I wish I'd started earlier,' she said, 'but I'm so glad I didn't wait any longer.' That's the energy. That's the vibe. Be Sarah. Don't be Dave.
── Today Is a Very Good Day ──
So here we are. Whether you're 35 and feeling like you should have started at 25, or 45 and feeling like you should have started at 35, or 55 and feeling like the ship has sailed — it hasn't. It really, genuinely hasn't. The ship is at the dock. The gangplank is down. The captain — who is also you — is waiting. All you have to do is step on board.
Open the ISA. Set up the direct debit. Buy the ETF. And then — this is the important bit — forgive yourself for not starting earlier. The past is the past. You can't change it, and beating yourself up about it doesn't add a single pound to your portfolio. What you CAN change is what happens next. Today. This afternoon. Right now.
You're going to be 70 anyway. You're going to be 75 anyway. You're going to be 80 anyway — if you're lucky, which I sincerely hope you are. The version of you at 75 who opened an ISA today is going to be significantly happier than the version who didn't. Not because they're rich. Because they did something. Because they took control. Because they stopped waiting and started doing. That version of you — the 75-year-old who started today — is looking back at this moment with a quiet smile and thinking: 'Good decision. Glad I did that.'
The best time to plant a tree was 20 years ago. The second best time is now. But here's the bit everyone forgets — the tree you plant at 55 still gives shade at 75. Plant the tree. Start today. You'll thank yourself later — and later arrives faster than you think.

All investments carry risk and can go down as well as up — sometimes by a lot, sometimes for a long time.
