Vanguard VTSAX Review 2026: Is It Still the Best Index Fund?

What Is VTSAX?

VTSAX (Vanguard Total Stock Market Index Fund Admiral Shares) is one of the most famous and widely held index funds in the world. It tracks the CRSP US Total Market Index, giving investors exposure to virtually every publicly traded U.S. company — approximately 3,600 stocks across large, mid, and small-cap companies.

VTSAX was popularized by personal finance author JL Collins in his book "The Simple Path to Wealth," where he described it as the one fund that can make you a millionaire if you invest in it consistently over decades.

VTSAX Key Facts (2026)

• Expense ratio: 0.04% — $4 per year on $10,000 invested
• Minimum investment: $3,000
• Number of holdings: ~3,600 U.S. stocks
• Dividend yield: approximately 1.3-1.5%
• Available at: Vanguard primarily (can hold at other brokerages but may have transaction fees)
• ETF equivalent: VTI (same index, same holdings, $0 minimum, trades like a stock)

Historical Performance

VTSAX has delivered strong long-term returns that closely mirror the overall U.S. stock market. Over any 20-year period in its history, it has delivered positive returns. Its performance closely tracks the S&P 500 — typically within 0.1-0.3% annually — with slightly more small-cap exposure providing occasional outperformance.

VTSAX vs. The Competition

VTSAX vs. FZROX (Fidelity)

FZROX charges 0.00% vs VTSAX's 0.04%. Over 30 years on $100,000, this difference is roughly $13,000 — real but not life-changing. FZROX is only available at Fidelity; VTSAX is available at Vanguard and can be held elsewhere.

VTSAX vs. VTI

Both track the same index with the same expense ratio (0.04%). VTI is the ETF version — it has no minimum investment and trades throughout the day. VTSAX requires a $3,000 minimum but allows automatic dollar-amount investing. For most investors, VTI is more accessible.

VTSAX vs. VOO (S&P 500)

VOO tracks only the S&P 500 (500 largest companies). VTSAX adds mid and small-cap exposure. Historically, performance has been nearly identical — within 0.2% annually. VTSAX is slightly more diversified.

Is VTSAX Still Worth It in 2026?

Yes — VTSAX remains an excellent index fund. Its 0.04% expense ratio is among the lowest available, its diversification is exceptional, and Vanguard's investor-owned structure ensures it will remain low-cost. The $3,000 minimum is a barrier for some beginners, but Fidelity's FZROX (0.00%, no minimum) is an excellent alternative for those just starting out.

For investors already at Vanguard with $3,000+ to invest, VTSAX is a superb choice. For beginners, VTI (no minimum) or FZROX (free at Fidelity) may be more accessible entry points.
