A 401(k) lets you invest pre-tax income—often with free employer matching—so you’re saving before you see your paycheck. IRAs, especially Roth IRAs funded with after-tax dollars, offer another self-directed path where earnings and withdrawals grow tax-free, making early contributions particularly potent.
Money in retirement accounts must be invested to grow; stocks offer high long-term returns but with volatility, bonds provide stability with lower gains, and index funds bundle many assets for broad diversification. Staying invested through market cycles—rather than timing ups and downs—is key to reliable growth over decades.
To open a Roth IRA, select a brokerage (e.g. Fidelity or Vanguard), complete an online application (minors use custodial accounts), and transfer funds—even $50 a month builds habit and balance. Inside the account, purchase low-cost index funds, set up automated contributions, and avoid common pitfalls like panic-selling during market dips.
Reaching $100K in retirement assets is the hardest but most transformative milestone: once attained, compound interest accelerates your balance without extra effort. Maximize tax-advantaged contributions, boost income via side hustles, live below your means, and invest consistently to clear this threshold and let growth work for you.
