What a 401k actually is.

A 401k is not an investment.
It's a tax label.

It refers to a section of the IRS code.
That's it.

It just tells the government how your investment will be taxed.

In a Roth 401k, you pay taxes now and it grows tax free.
In a traditional 401k, you defer taxes until later.

Knowing the difference is not trivia.
It can save you thousands of dollars over time.

Stop treating your 401k like a magic box.
Understand what it actually is.
And use the rules to your advantage.
