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.

The math checks out but I think you are being a bit conservative with the return assumptions. Historical averages suggest higher.
