How do I open the TSP Mutual Fund Window?

Log into your TSP account at tsp.gov, navigate to 'Mutual Fund Window,' and follow the enrollment steps. You'll need a minimum TSP balance. Capital Wealth can walk you through the process.

What funds are available?

Over 5,000 mutual funds from major providers including Fidelity, Vanguard, T. Rowe Price, American Funds, PIMCO, and many others. Individual stocks and ETFs are not available — only mutual funds.

Should I move all my TSP money to the Window?

Almost certainly not. The core TSP funds (especially C, S, and I) have rock-bottom expense ratios. The best strategy usually combines core TSP funds with targeted Mutual Fund Window selections for asset classes the core doesn't cover.

You'll pay a $28.75 annual maintenance fee, plus the expense ratios of whatever mutual funds you select (these vary from 0.03% to over 1%). There may also be per-trade fees. We ensure your total costs are justified by the added diversification.

Can I move money back to core TSP?

Yes. You can transfer money between the Mutual Fund Window and your core TSP allocation. There are no penalties for moving back.
