401(k)

A retirement account you get through your employer. Money comes straight out of your paycheck before you see it, and the taxes are delayed until you withdraw it in retirement (or paid up front if your plan offers a Roth 401(k)). Pulling money out before age 59½ usually means taxes plus a 10% penalty.

50/30/20 Rule
