[quote=ucodegen][quote=flu]Why would a Roth 401k be odd? Aside from a matching contribution, some of us are disqualified from contributing to a a Roth IRA and have preconditions that prevent us from doing a backdoor Roth IRA. Also With a Roth 401k, one can contribute up to 18k/year if one choices not to contribute to a traditional 401k. I think that’s a lot more than most people can can contribute to a Roth IRA.[/quote]
Ok, understand it is an income limit and contribution limit issue wrt selection.

Roth 401ks would tend to limit your selection of investments/mutual funds to the ones that your plan provid(es/ed).

And yes, 18k is a lot more than upper limit on Roth IRA.[/quote]

Agreed, but in my case, the fund choices are all vanguard index and select fidelity funds, the same I put my own money into elsewhere.

Also since my average job expectancy is 2-3 years per employer, they’ll get rolled over anyway.
