Key Takeaway: The earlier you start, the easier it is!


Step 1: Choose the Right Investment Accounts

Before picking stocks, maximize tax-advantaged accounts:

1. 401(k) / Employer Plans

  • Contribute enough to get the full employer match (free money!).
  • 2025 Contribution Limit: **23,000∗∗(30,500 if 50+).

2. Roth IRA (Best for Tax-Free Growth)

  • 2025 Limit: **7,000∗∗(8,000 if 50+).
  • Best for: Long-term compound growth (no taxes on withdrawals).

3. Taxable Brokerage Account

  • For extra savings beyond retirement accounts.
  • Best at Fidelity, Vanguard, or Schwab.

Step 2: Invest in the Right Assets

$1M portfolio should be diversified across:

1. Index Funds (80-90% of Portfolio)

  • Vanguard S&P 500 ETF (VOO) – 0.03% fee, tracks the top 500 U.S. companies.
  • Vanguard Total Stock Market ETF (VTI)—Broad U.S. market exposure.
  • Vanguard Total International Stock ETF (VXUS)—Global diversification.

Why?  Low fees, automatic diversification, and historically ~10% annual returns.

2. Dividend Stocks (5%-10% for Passive Income)

  • Schwab U.S. Dividend Equity ETF (SCHD) – Top dividend growers.
  • Realty Income (O)—A monthly dividend payer.

Why?  Reinvested dividends accelerate compounding.

3. Bonds (10-20% for Stability)

  • Vanguard Total Bond Market ETF (BND) – Low-risk income.
  • Only increase bond allocation as you near retirement.

Step 3: Automate & Stay Consistent

  • Set up automatic transfers to your investment accounts.
  • Increase contributions annually (e.g., by 1-2% each year).
  • Never panic-sell during market crashes (stay the course!).

Sample $1M Portfolio (Based on Age)

Example 1: Aggressive Growth (Age 25-40)

Investment Allocation
VTI (Total Stock Market) 70%
VXUS (International Stocks) 20%
BND (Bonds) 10%

Projected Growth: 450/month → 450/month → 1M by 65 (7% return).

Example 2: Balanced Growth (Age 40-55)

Investment Allocation
VOO (S&P 500) 60%
SCHD (Dividend Stocks) 20%
BND (Bonds) 20%

Projected Growth: 1,500/month → 1,500/month → 1M by 65.

Example 3: Catch-Up Plan (Age 55+)

Investment Allocation
VOO (S&P 500) 50%
SCHD (Dividend Stocks) 30%
BND (Bonds) 20%

Projected Growth: 5,000/month→1M in 10-15 years.


Step 4: Minimize Fees & Taxes

  • Avoid actively managed funds (high fees eat returns).
  • Hold investments long-term (lower capital gains taxes).
  • Use tax-loss harvesting in taxable accounts.

Step 5: Monitor & Rebalance Annually

  • Check the portfolio once a year.
  • Rebalance if allocations drift (e.g., sell stocks if they exceed 70%).
  • Adjust risk as you near retirement (more bonds over time).

Common Mistakes That Delay $1M

❌ Starting too late (time is your biggest advantage).
❌ Trying to time the market (Just keep investing!).
❌ Picking individual stocks (mostly underperforming index funds).
❌ Paying high fees (even 1% fees cost $300,000+ over 40 years!).

  3. Automate & ignore short-term noise.
