Can someone please explain Roth IRA vs. 401K (like i'm five)

I keep hearing different things from different people about this and I couldn't understand which is better/worse for retirement planning.

You contribute to Roth IRA with post-tax dollars and get to take out your money when you retire tax-free whereas a regular 401k takes pre-tax dollars but you get taxed when you take it out.

Simply, Roth=Pay taxes now Traditional=Pay taxes later

As for what is better for you it depends on your situation and what your current/future tax bracket will be.
