How Does a 401k Work?

A 401k is an employer-sponsored retirement savings account that lets you invest pre-tax dollars. Your money grows tax-deferred until withdrawal in retirement, allowing compound growth over decades.

Frequently Asked Questions

How much should I contribute to my 401k?
At minimum, contribute enough to capture your full employer match — that is free money. A common target is 10–15% of your gross income for retirement security.

What is the 401k contribution limit?
In 2024, the IRS limit is $23,000 per year (plus $7,500 catch-up contribution if you are 50 or older).

Can I withdraw from my 401k early?
You can withdraw before age 59½, but you will typically owe income taxes plus a 10% early withdrawal penalty. Exceptions exist for hardship withdrawals.
