How this one decision in your twenties can impact whether you end up rich or poor

Getting your first proper salary in your twenties feels amazing. That is, until reality hits and you wonder where all that money went by month’s end. While most young people either blow their entire paycheck or stress about complex investment strategies, there’s one simple move that financial experts swear by.

The secret isn’t about earning more or following complicated budgets. It’s about what you do in the first few minutes after your salary lands in your account, according to Fred Harrington, CEO of Proxy Coupons, who has spent years helping people make smarter financial decisions through strategic savings and deal-hunting.

Fred sees so many young people earning decent money but still living paycheck to paycheck, says Fred. Income isn’t the main difference between those who build wealth and those who don’t. Instead, it’s having a system that works automatically, without willpower or constant decision-making.

According to Fred, the first thing any money-savvy person should do when their salary arrives is split a large portion of it immediately into three separate bank accounts or pots, each with a specific purpose and quirky name to make money management more engaging.

The three-account system that changes everything

Fred’s strategy is all about hacking your brain’s natural tendencies around money.

1. The Future Me Fund (Long-Term Investing)

This account gets 20% of your salary and is strictly for long-term wealth building. Your future self will thank you for every pound you put away now, explains Fred. Compound interest is like a snowball – it starts small but becomes unstoppable over time.

The key is treating this transfer like a non-negotiable bill. Most people invest what’s left over, but successful people invest first and spend what’s left.

2. The Life Happens Account (Short-Term Goals)

Allocate 15% here for upcoming trips, moving costs, or that laptop you’ve been eyeing. This account prevents you from raiding your long-term savings when you want something specific.

Unlike your emergency fund, this money is meant to be spent – just strategically. It gives you permission to enjoy your money guilt-free because you know your future is already secured.

3. The Oh Snap! Emergency Fund

This gets 10% and exists purely for genuine emergencies – job loss, medical bills, or urgent car repairs. Do not use this for impulse purchases or last-minute holidays, Fred clarifies. It’s your financial safety net that lets you sleep peacefully at night.

The remaining 55% stays in your main account for essential living costs like rent, bills, groceries, and day-to-day spending.

Why physical separation beats mental math

Most financial advice suggests mentally allocating money into different categories, but Fred argues this approach fails because of basic human psychology.

When all your money sits in one account, your brain sees the total and thinks it’s all available to spend, he explains. Physical separation removes temptation and makes good financial habits automatic.

Research in behavioural economics supports this approach – people spend less when money is physically separated rather than just mentally categorised. It’s like having separate cookie jars instead of one big jar where you promise yourself you’ll only eat a few, Fred adds with a laugh.

The ideal breakdown that works

Fred recommends this salary split for most twenty-somethings:

  • 55% for essential living costs (rent, bills, groceries, daily expenses)
  • 20% for the Future Me Fund (long-term investing)
  • 15% for the Life Goals Account (short-term savings goals)
  • 10% for the Oh Snap! Emergency Fund

The percentages aren’t set in stone, Fred emphasises. If you’re living with parents, bump up your investing percentage. If you’re in an expensive city, adjust accordingly. The key is having the system, not perfect numbers.

Money mistakes that keep twenty-somethings broke

Even with good intentions, young earners often sabotage their financial progress through predictable mistakes.

Lifestyle Creep: Every salary increase becomes an excuse to upgrade everything, warns Fred. Your flat-screen TV doesn’t need to get bigger just because your paycheck did.

No Emergency Buffer: Without emergency savings, one unexpected expense can derail months of financial progress. I’ve seen people max out credit cards because their laptop died.

Peer Pressure Spending: Social media makes everyone else’s life look expensive. Your Instagram feed isn’t a financial planning tool, Fred jokes. Stop trying to keep up with people who might be drowning in debt behind those perfect posts.

All-or-Nothing Thinking: Many young people either save nothing or try to save impossible amounts. Start with whatever you can, even if it’s just 5%. Building the habit matters more than the amount.

Automate good money habits in your twenties

Aside from having to do with money, the three-account system is about peace of mind. When you automate good financial habits in your twenties, you’re setting yourself up for decades of reduced money stress. I’ve watched people transform from chronic overspenders to confident savers simply by removing the daily decision-making around money.

What excites me most is seeing young people discover they can afford the things they want when they plan properly. Instead of impulse buying and regretting it later, they’re making deliberate choices about their money. That shift from reactive to proactive spending can change your entire relationship with money, not just your bank balance.

The compound effect goes beyond just investment returns. When you start your career with solid money habits, you avoid the debt spiral that traps so many people. You’re not spending your thirties digging out of credit card holes or your forties panicking about retirement. Financial wellness in your twenties creates a ripple effect that improves every decade that follows.
