> If you max out your 401(k) you are saving about $20k/yr while only reducing your taxable income by ~$15k/yr depending on your marginal tax rate. A Roth adds another $6k to that if you're under the cap (something like $140k for 2020)

Even if you are above the Roth cap, you can contribute post-tax $6k to a tradtional IRA, then immediately roll into a Roth IRA. This is known as a "backdoor Roth".

Additionally, some employer 401(k) plans allow you to contribute post-tax money to your 401(k). The IRS specifies an upper limit of the total of [employee pre-tax + employer match + employee post-tax], which was $57k in 2020. The post-tax portion of the above can also be rolled into a Roth IRA. This is commonly referred to as the "mega-backdoor Roth"

Also, don't forget catch-up contributions to each if you are over 50.

Point is if you have the income to support it, you can save much more in a tax advantaged way than just that $19.5k pre-tax 401(k). Please look up the tax consequences of any of these options before doing them. They are straightforward but contain a few pitfalls, such as the pro-rata rule affecting rolling over traditional IRAs into Roth IRAs.
