Having a 401(k) can help you retire. But it’s far from the only available option. Many people don’t have a 401(k) because they choose to invest independently or because their employer doesn't offer one.
In fact, not having a 401(k) can be a benefit because it forces you to plan your own retirement.
It’s possible to achieve similar retirement benefits through an IRA. You can also obtain further tax-advantaged growth through a health savings account (HSA) and some life insurance policies, too.
