Never leave the match on the table

A typical match β€” 50% of contributions up to 6% of salary β€” is an instant 50% return. Contribute at least enough to get the full match before investing anywhere else.

Roth or Traditional?

Traditional contributions save tax now and are taxed when withdrawn; Roth contributions are taxed now and grow tax-free. With the same budget, the two give the same result when your tax rate is unchanged. If you expect a lower rate in retirement, Traditional wins; if higher, Roth wins. Many people split contributions to diversify.
