Open a brokerage account (choose one that offers S&P 500 index funds/ETFs)
Compare S&P 500 options: ETFs (e.g., VOO, IVV, SPLG) or index mutual funds
Check total expense ratio (expense fee) and trading costs (for ETFs)
Verify the fund tracks the S&P 500 (look for “S&P 500 Index” or similar benchmark)
Decide how much to invest and your contribution schedule (one-time or recurring)
Place an order for the ETF (market or limit order) or mutual fund (typically at end-of-day NAV)
Use dollar-cost averaging if investing over time (set recurring deposits)
Reinvest dividends (if available) or schedule dividend reinvestment
Review and rebalance periodically based on your target allocation
Monitor holdings and fees, and confirm the fund remains an S&P 500 index product
Keep records for taxes and account reporting requirements in your jurisdiction
