Why Retirement Planning in Your 30s Matters

Your 30s are the most powerful decade for retirement planning because you have 30-35 years of compound growth ahead. In 2025, the average American in their 30s has just $18,000 saved for retirement, but experts recommend 1–2x your annual salary by age 35. By maximizing your 401k contributions ($23,000 limit in 2025), contributing to a Roth IRA ($7,000 limit), and investing in low-cost index funds, you can realistically build a $1 million+ retirement portfolio by age 65. This guide covers proven retirement savings strategies, investment allocation for your 30s (80% stocks, 20% bonds), and how to take advantage of employer 401k matching to accelerate your wealth building. Protecting your family with life insurance is also crucial during this decade.
