If you’re in your twenties, retirement probably feels like it belongs to a completely different person. Someone older, slower, and a long way off. That’s fair enough. But the decisions you make (or don’t make) about your pension right now will shape what your life looks like in 40 years. And most people under 30 are getting some of the basics wrong.
Mistake #1: Opting Out of Your Workplace Pension
Auto-enrolment was supposed to fix the problem of young workers ignoring pensions. And it did help. But plenty of people still opt out within the first few months, usually because they’d rather have the extra cash in their pay packet.
That’s understandable when rent takes up half your salary. But here’s what you’re actually turning down: free money. Your employer is legally required to contribute to your pension on top of what you put in. If you’re on a qualifying scheme, they’ll add at least 3% of your qualifying earnings. You also get tax relief on your own contributions, which means the government is effectively topping you up too.
Opting out doesn’t just delay your pension. It means you’re walking away from contributions you’ll never get back.
Mistake #2: Ignoring Employer Matching
This one catches a lot of people out. Some employers will match your contributions up to a certain percentage. So if you put in 5%, they’ll put in 5%. But if you only contribute the minimum, you’re leaving their extra money on the table.
It’s one of the few situations in life where someone is offering to give you more money for doing very little, and most young workers don’t even check what their employer’s matching policy is. A quick look at your pension scheme documents or a conversation with HR could make a genuine difference to your pot over the next few decades.
Mistake #3: Relying on the State Pension
A lot of people under 30 assume the state pension will cover them when they retire. It won’t. The full new state pension is currently £241.30 a week. That works out to about £12,550 a year. You can live on that, but it won’t be comfortable, and it won’t cover much beyond the basics.
On top of that, you need 35 qualifying years of National Insurance contributions to get the full amount. If you’ve had gaps in employment, time abroad, or years spent freelancing without paying Class 2 NICs, your state pension could end up being even less.
The state pension was designed as a safety net, not a retirement plan. Treating it as your main income source is one of the biggest miscalculations younger workers make.
Mistake #4: Underestimating Compound Growth
This is the one that really costs people. Compound growth means your investment returns generate their own returns over time. The earlier you start, the more powerful this effect becomes. And the difference between starting at 22 and starting at 32 is enormous.
Someone who puts £100 a month into a pension from age 22, with average annual growth of around 5%, could end up with roughly £136,000 by the time they’re 60. Start the same contributions at 32 and you’d have closer to £73,000. That’s a gap of over £60,000, and you’d have only contributed £12,000 less in total. The rest is lost growth.
For anyone with decades ahead of them, even getting professional financial planning management advice once in your twenties or thirties can help you set the right contribution levels and fund choices, so compound growth does the hard work for you.
Mistake #5: “I’ll Sort It Out Later”
This is probably the most common pension mistake of all, and it’s the hardest to argue against at the moment. When you’re 25, retirement is 40 years away. There are more pressing things to deal with: rent, student loans, car insurance, actually having a life.
But pension contributions don’t need to be huge to matter. Even small amounts in your twenties will do more heavy lifting than large contributions in your fifties, thanks to that compounding effect. The maths backs you up completely if you start early, even with modest sums.
The Real Cost of Waiting
Pensions aren’t exciting. Nobody’s posting about their SIPP on social media. The gap between someone who starts paying attention at 22 and someone who waits until 35 can easily run into tens of thousands of pounds by retirement, potentially six figures if you’re contributing more than the minimum. The biggest advantage young people have is time, and most of them don’t realise they’re wasting it.
Even if all you do is stay opted into your workplace scheme, check your employer’s matching policy, and bump your contributions up by 1% a year, you’ll be in a dramatically better position than the majority of your peers. You don’t need to become a pension expert. You just need to stop ignoring it.
Please note: Investment values fluctuate. You could receive back less than you put in, and the income from your investments isn’t guaranteed to stay the same. What’s happened in the past isn’t necessarily a sign of what will happen next.
