Building wealth through monthly investing comes down to picking low-cost, diversified funds and staying consistent for decades. Here’s how the top 10 stack up.
Top picks for monthly investing:
- FXAIX (Fidelity 500 Index) – 0.015% fee, $0 min, S&P 500 core holding.
- SWPPX (Schwab S&P 500) – 0.02% fee, $1 min, near-identical to FXAIX.
- FZROX (Fidelity ZERO Total Market) – 0% fee, broadest US exposure.
- VTSAX (Vanguard Total Stock Market) – 0.04% fee, $3,000 min, the classic.
- VIGAX (Vanguard Growth Index) – 0.05% fee, growth tilt, higher volatility.
- FCNTX (Fidelity Contrafund) – ~0.74% fee; manager Danoff retiring late 2026.
- TRBCX (T. Rowe Price Blue Chip Growth) – ~0.70% fee, strong active track record.
- AGTHX (Growth Fund of America) – Class A carries a sales load; best via 401(k).
- VWELX (Vanguard Wellington) – 65/35 balanced, gentler ride, since 1929.
- VTIAX (Vanguard Total Intl) – non-US diversifier, not a standalone core fund.
For most beginners, FXAIX or SWPPX alone is the simplest, cheapest starting point.
