The L funds within the Thrift Savings Plan (TSP) are designed to be an all-in-one solution for federal employees, but they often come with hidden problems. The vast majority of feds do not fully understand how these funds work or if they actually make sense for their specific situation. While the idea of picking a fund based on your retirement date and forgetting about it sounds appealing, this approach can lead to significant issues down the road. Let us explore how the L funds operate, whether they are the right choice for you, and what alternative strategies might offer better results.
The Default Selection Trap
The primary issue with L funds is that they only consider one factor: your target retirement date. For example, if two federal employees both plan to retire in 2030 and have a million dollars in their TSP, they might both choose the L 2030 fund. However, their financial goals could be entirely different. One might rely solely on their TSP to fund their lifestyle, while the other might have a large inheritance and want to leave their TSP to charity or their children. Despite these vastly different objectives, the L fund invests their money identically. It ignores crucial factors such as the size of your pension, your risk tolerance, and any outside assets you may have.
The Conservative Shift
As L funds approach their target date, they automatically become more conservative. Eventually, they all merge into the L Income Fund, which is exceptionally conservative, consisting of about 75% G Fund and F Fund. While some retirees may prefer this level of safety, for the average person, it is often too conservative. Retirement can last 20, 30, or even 40 years. If the majority of your money is barely keeping up with inflation while you are taking withdrawals, your savings could be depleted much faster than anticipated due to a lack of growth.
The Opportunity Cost
The cost of being too conservative can be staggering. A mere 2% difference in annual returns over a 30-year career or retirement can result in a difference of over $250,000. Imagine what an additional quarter of a million dollars could do for your retirement lifestyle. Getting your investments aligned with your actual needs and goals makes a massive difference over time. Relying on a default fund that does not match your situation can mean leaving a significant amount of money on the table.
The Set It and Forget It Trap
Another major drawback of the L funds is their rigid adherence to a pre-programmed schedule. Regardless of what is happening in your personal life or the stock market, the L funds will continue to adjust their allocation based solely on the calendar. They follow a computer algorithm without any flexibility. While this hands-off approach works for some, most people benefit from having more control over their investments, allowing them to make adjustments based on real-world conditions and personal life changes.
When L Funds Make Sense
Despite their flaws, L funds are not entirely bad. They can be a good choice if you have absolutely zero interest in tracking the market and want automatic diversification. They are also beneficial for individuals who tend to panic sell and move everything to the G Fund when the market drops. If you need a system that manages your investments so you do not touch them, the L funds, with their daily rebalancing, can serve that purpose well. However, it is essential to understand the pros and cons before committing to this strategy.
Alternative Investment Approaches
If you decide the L funds are not for you, the alternative is to invest directly in the core TSP funds. The C, S, and I funds offer aggressive growth, while the G and F funds provide conservative stability. By managing these funds yourself, you can tailor your mix to fit your specific needs. Generally, younger employees or those in the middle of their careers should focus on growth. As retirement approaches, you can manually increase your allocation to the G and F funds to add stability, rather than letting an L fund dictate the timing. This personalized approach ensures your investments align with your unique retirement goals.
