Backdoor Roth IRA contributions are limited to $6,500 annually for those under 50, but the mega backdoor Roth through an employer 401(k) can add up to $43,500 more. Not all plans allow this, so check your summary plan description. For more on this topic, see Frugal Living Tips.

My financial advisor recommended the exact same approach. Nice to see it validated with actual numbers.
