Retirement Savings: Early Start and Contribution Amount Outweigh Investment Choices, Study Finds

Starting to save for retirement early and consistently contributing a significant portion of income has a greater impact on long-term financial security than the specific investment choices made, according to a new analysis of hypothetical retirement savers.

The study, which modeled the financial outcomes of two individuals – Laura and JR – both beginning their careers at age 25, demonstrated that even a slight delay in saving, or a lower contribution rate, could significantly impact final retirement balances. Laura, who immediately contributed 10% of her $75,000 salary to her 401(k) and benefited from a company match, ultimately amassed a portfolio exceeding $3 million over 40 years. JR, who waited five years to begin saving and contributed only the minimum to receive the full company match, ended up with approximately $2 million.

While JR opted for a target-date fund with a 15% allocation to private equity and private credit, hoping to accelerate his savings, the analysis showed that the slightly higher annualized return of 8.9% (compared to Laura’s 8.4% in a public-market-only fund) was overshadowed by the benefits of early and consistent saving. This finding aligns with broader research on the power of compound interest and its impact on long-term wealth accumulation. The difference in outcomes highlights the importance of prioritizing savings habits, especially as many Americans face challenges in adequately preparing for retirement.

Researchers cautioned that the results are based on specific assumptions, including consistent employment and long-term market returns, and that private market investments carry their own risks. However, the core takeaway remains: maximizing contributions and starting as early as possible are the most reliable paths to a secure retirement. Morningstar analysts noted that private equity funds should be viewed as another form of active management, where returns can vary significantly.

Officials stated that further research will be conducted to explore the evolving landscape of retirement investment options and their potential impact on savers’ outcomes.
