How much is your 401k down?

Agree but only after you max out your pretax max and if you can afford to contribute beyond it. Most folks cannot.

Yes, max out the pre-tax first. I am the second salary in the home and we live below our means so I can max pre-tax and then an additional 20K into the backdoor roth. You just have to make sure with company match that you do not go above 57K total (if under 50 that's the total max).
