October TSP Fund Performance

For federal employees, the TSP is a powerful retirement benefit. With low fees, government backing, and a variety of investment options, it offers a strong foundation for growing and protecting your savings.

The G Fund is unique to the TSP, providing stability through U.S. Treasury securities, making it a reliable anchor for your portfolio, especially as retirement nears.

But “safe” doesn’t mean hands-off. Stock-focused funds like the C, S, or I Funds can fluctuate significantly, while the G Fund’s conservative returns may lag behind inflation over time.

Looking at 2025 performance so far, the I Fund has been the top performer overall. In October, the C Fund led monthly returns with 2.34%, while the S Fund returned 1.16% and is up 12.47% for the year, behind the C Fund’s 17.49% gain. Among the Lifecycle (L) Funds, the L 2027 Fund posted a 2025 return of 20.40%, delivering higher gains than the L 2055, L 2060, and L 2065 Funds.

A few practical tips:

• If you’re early in your career, a higher stock allocation can help capture long-term growth.
• If retirement is near, consider shifting toward more conservative funds like the G or F Fund or the L-Income Fund.
• Review and rebalance regularly to keep your portfolio aligned with your goals and risk tolerance.

The TSP is a valuable tool, but making sure your allocations match your timeline and comfort with risk can make a significant difference in your retirement outcomes. A Federal Retirement Consultant (FRC®) can give you a complimentary analysis and tailor a plan to meet your retirement goals.
