A 401(k) is like a retirement starter pack, especially if your employer offers a match (which is free money!). Contributions are taken out of your paycheck before taxes, which lowers your taxable income now, however you’ll pay taxes when you withdraw in retirement. It’s a great choice because it’s automatic – set it, forget it, and watch savings grow. Be aware that if you withdraw early, you'll face income taxes as well as a 10% penalty. This is your meant to be long-term, can't-touch-it money.
Example: If you’re earning $50,000 a year and contribute 10% to your 401(k) with a 3% employer match, that’s $6,500 saved annually. Over 30 years, assuming a 6% return, that could grow to over $500,000.
