The TSP G Fund currently pays an interest rate of 3.75% as of June 2026, guaranteed by the U.S. government and adjusted monthly based on the average yield of outstanding Treasury securities.
Can you lose money in TSP G fund?
No, you can't lose money in the TSP G Fund because all principal and interest payments are guaranteed by the U.S. government.
Here's the thing: the G Fund invests in short-term U.S. Treasury securities issued specifically for the Thrift Savings Plan. Since these are backed by the full faith and credit of the U.S. government, your investment is completely protected from market risk, credit risk, or default. Honestly, this makes the G Fund the only truly zero-risk option in the entire TSP lineup.
What is the average rate of return for the G fund?
The average annual return for the TSP G Fund from 2000 to 2025 is about 3.3%, based on historical performance data from the Federal Retirement Thrift Investment Board.
Now, if you look at the period from 2020 to 2025, the G Fund's returns bounced between 1.5% and 4.0% annually. That reflects the low-interest-rate environment we've been stuck in for most of that time. The fund's rate adjusts monthly and tracks short-term U.S. Treasury yields pretty closely—those tend to be less volatile than longer-term bonds. The causes of convection current in financial markets often mirror broader economic forces.
What is TSP G fund paying?
The TSP G Fund is currently paying 3.75% interest as of June 2026, which is the rate credited to participant accounts for that month.
That rate gets set monthly by the Federal Retirement Thrift Investment Board, and it's based on the weighted average yield of all outstanding Treasury securities with maturities of 4 years or less. Because the U.S. government guarantees both your principal and the interest, the G Fund gives you a risk-free way to preserve your capital while earning a modest return.
Should I put all my money in the G fund?
No, putting all your TSP money in the G Fund generally isn't the best move because of inflation risk over time.
Here's why: while the G Fund protects your principal, its returns often can't keep up with inflation—especially during periods like 2022–2025 when prices were climbing fast. A balanced mix that includes stock-based funds (like the C, S, or I Funds) helps your savings grow faster to outpace rising costs. Think about your age, how much risk you're comfortable with, and when you plan to retire before making any decisions. For personalized advice, talk to a FINRA-registered financial professional.
What is safest TSP fund?
The G Fund is the safest TSP fund because it carries no credit, market, or default risk.
It holds short-term U.S. Treasury securities issued specifically for the TSP. While it won't make you rich, it does preserve your capital and delivers steady, predictable returns. That makes it perfect for conservative investors or anyone getting close to retirement who wants stability. The F Fund (bond index) is a close second, but it does carry some market risk thanks to fluctuating bond prices.
Which is better G fund or F fund?
The G Fund is safer and more stable, while the F Fund tends to offer higher returns with moderate risk over the long term.
The G Fund pays interest tied to short-term Treasury yields and guarantees your principal, making it ideal for people who hate taking risks. The F Fund, which tracks the Bloomberg U.S. Aggregate Bond Index, invests in government, corporate, and mortgage-backed bonds. It can deliver higher returns when interest rates drop but may lose value when rates rise. Historically, the F Fund has beaten the G Fund most years, but with slightly more ups and downs.
Why is the G fund so low?
The G Fund’s low interest rate reflects the Federal Reserve’s monetary policy and historically low Treasury yields, which have stuck around since the 2008 financial crisis.
In 2026, the fund's 3.75% yield is still below long-term averages thanks to low inflation and cautious Fed policy. While this protects you from losing money, it also limits how much your savings can grow. Over time, if you rely only on the G Fund, you might fall behind inflation—especially during periods like 2022–2023 when prices jumped over 8%. Mixing in stock funds can help make up for that shortfall. Understanding how currents affect broader systems can provide useful perspective on economic flows.
What is the C fund?
The C Fund tracks the S&P 500 and invests in 500 of the largest U.S. companies, such as Apple, Microsoft, and Amazon.
It's one of the most popular TSP funds because it gives you broad market exposure with super-low fees. Over the past 20 years, it's averaged about 10% returns annually. That's great for long-term growth, but remember—your balance can take a hit during downturns like the 2008 crash or the 2020 pandemic. Still, it's beaten most other TSP funds over full market cycles.
What is a good rate of return on TSP?
A good long-term average return for a diversified TSP portfolio is 6% to 8% annually, depending on your fund mix.
For example, a moderate-risk portfolio with 60% in stock funds (C, S, I) and 40% in bonds (F, G) typically delivers 6–7% returns over decades. Aggressive portfolios (80–100% stocks) can average 8–10%, while conservative ones (40–60% stocks) may return 4–6%. These numbers match historical market performance, but they're not guarantees. Always match your expectations to your risk tolerance and timeline.
What is the average TSP balance at retirement?
As of 2025, the average TSP balance for retirees aged 60–69 is $182,100, based on Federal Retirement Thrift Investment Board data.
| Age Group | Average Contribution Rate | Average Balance (2025) |
|---|---|---|
| 60–69 | 11% | $182,100 |
| 70–79 | 12% | $171,400 |
| All Ages | 9% | $95,600 |
This data reflects contributions, market performance, and withdrawal patterns. Higher balances usually mean consistent saving and longer participation in the TSP. People with higher incomes and steady contributions often blow past these averages.
How much should I have in my TSP at 40?
By age 40, aim to have 3 times your annual salary saved in your TSP—for example, $150,000 if you earn $50,000.
That benchmark comes from Fidelity's retirement savings guidelines. If you started saving at 25 with steady contributions and an average 7% annual return, hitting 3x salary by 40 is totally doable. Use the TSP's calculator to check your progress and tweak your savings rate as needed. Starting early and staying consistent matters way more than trying to time the market. The current technologies for use in business and industry can also impact your career growth and earning potential.
Should I keep my money in TSP after retirement?
Yes, you can leave your money in the TSP after retirement if you don’t need it right away—it will keep growing tax-deferred.
Once you retire, you can delay withdrawals until age 72 (Required Minimum Distributions apply). Keeping funds in the TSP avoids early withdrawal penalties and lets you keep investing in those low-cost funds. You can also take partial withdrawals or set up monthly payments. Compare fees and options with other accounts, like IRAs or annuities, to make sure the TSP is still your best bet.
What is the most aggressive TSP fund?
The I Fund is the most aggressive TSP fund because it invests in developed-market international stocks.
The I Fund tracks the MSCI EAFE Index and holds companies from Europe, Japan, and other developed economies. It's the wildest ride in the TSP lineup, with losses that can top 50% during severe downturns (like the -60.89% drop in 2008–2009). But if you've got a 20+ year horizon, it also offers the highest long-term growth potential. Only use it if you can stomach some serious short-term swings.
Which is the best fund to invest in TSP?
There is no single “best” TSP fund—the right choice depends on your age, risk tolerance, and retirement timeline.
- C Fund – Tracks the S&P 500; great for long-term growth.
- S Fund – Small U.S. companies; higher growth potential with higher risk.
- I Fund – International stocks; diversifies globally but adds volatility.
- F Fund – Bonds; stabilizes portfolios during market downturns.
- G Fund – Safe and stable; preserves capital but may not beat inflation.
- L Funds – Pre-mixed, age-appropriate portfolios; best for hands-off investors.
The Texas current state constitution outlines legal frameworks that may influence retirement planning in the state.
Is TSP same as 401k?
A TSP is similar to a 401(k) but is only available to federal employees and military service members.
Both plans let you save for retirement with tax-deferred dollars and offer employer matching (in the TSP, that's the Agency Automatic 1% and Matching contributions). The TSP usually has lower fees (just 0.04% in 2026) compared to most private-sector 401(k) plans. Unlike 401(k)s, TSP accounts stay with you even after you leave federal service, and you won't face the 10% early withdrawal penalty if you separate during or after the year you turn 55.
