Getting your first real paycheck is exciting, and how you divide it sets the tone for decades of financial habits. A simple rule-based approach beats overthinking it.

• Pay yourself first: Automate a transfer on payday so saving happens before you can spend. Starting with 20% of net income is a solid benchmark.
• Build an emergency fund before investing aggressively: Keep three to six months of expenses in a high-yield savings account; this cash prevents you from selling investments at the worst time.
• Capture the full employer match: If your company offers a retirement plan with matching contributions, contribute at least enough to get the entire match; it is free money that beats any other return.
• Invest the rest in broad index funds: Once your emergency fund is in place, direct extra savings into low-cost diversified funds rather than picking individual stocks.

The verdict: automate 20% savings first, build a safety cushion, and only then start feeding a simple index fund portfolio.
