Don't Leave the Match on the Table
Employer matching is an immediate 50%–100% return on your money — nothing in the market can reliably beat it. Always contribute at least enough to capture the full match before maxing out other accounts. A common match is "100% up to 3% of salary" — meaning you must contribute 3% to get a free 3%.
Traditional vs. Roth: Which Is Better?
If you expect to be in a higher tax bracket in retirement, Roth wins — you pay taxes at today's lower rate and withdrawals are tax-free. If you expect a lower bracket in retirement, Traditional wins — you defer taxes now at a higher rate. Most advisors suggest spreading across both for "tax diversification."
