Your 20s are the perfect time to start investing and lay the foundation for long-term financial success. By starting early, you can maximise compound growth, take advantage of your higher risk tolerance, and build strong financial habits that pay off for decades to come.
This guide explains the key benefits of starting early, practical investment strategies, and the best investment options for young investors in the UK.
Why Start Investing in Your 20s
Starting early offers huge advantages:
- Time is on your side – The earlier you invest, the longer your money has to grow.
- Compound growth – Small, consistent contributions can grow into significant wealth over time.
- Higher risk tolerance – You can afford to take on more growth-oriented investments since you have decades to recover from market fluctuations.
- Financial independence – Investing now sets you on a faster path to achieving financial freedom.
Key Investment Strategies for Your 20s
1. Build an Emergency Fund
Before investing, save at least three to six months of expenses in an easy-access savings account. This safety net protects you from unexpected financial setbacks.
2. Pay Off High-Interest Debt
Prioritise repaying high-interest debts like credit cards or personal loans. Manageable, lower-interest debts like student loans can be paid off gradually alongside investing.
3. Start Small and Stay Consistent
You don’t need a large sum to get started. Many investment platforms allow you to invest from £25 per month. Automating your contributions helps you stay consistent and build long-term wealth.
4. Diversify Your Portfolio
A well-diversified portfolio spreads risk and improves growth potential. Consider:
- Stocks & Shares ISAs – Tax-efficient access to stocks, bonds, and funds.
- Exchange-Traded Funds (ETFs) – Low-cost, diversified investments that track global indices.
- Pensions (Workplace & SIPPs) – Long-term savings with tax relief and potential employer contributions.
- Property or REITs – Options for exposure to property markets without direct ownership.
5. Maximise Employer Pension Contributions
If your employer offers a workplace pension, contribute enough to get the full employer match. It’s essentially free money. You can also explore Self-Invested Personal Pensions (SIPPs) for additional retirement savings flexibility.
6. Invest in Yourself
Your earning potential is your biggest wealth-building tool. Spending on education, professional training, or side hustles can increase your income and accelerate your savings.
