<prompt> Human: Hi!A little bit about my situation: - I am 22 years old- Just graduated college- Salary is at 110,000 28 tax bracket- Company matches 401k 50 up to 9,000 max- Given contribution options of pre-tax roth after-tax- I live in WA with no state income tax- Working in the tech field I am trying to figure out my best option for 401k investments. Being young, it seems simple to select the roth contribution option. Technically I should move up in tax brackets as I get older from moving up in positions, raises, etc... But since I am already in the 28 tax bracket, this is a chance that I might not get higher or I do a career change and I drop in my tax bracket.What contribution option would you suggest when considering these parameters? When it comes to investment options, I get completely lost and it goes slightly over my head in understanding.The company offers 2 tiers: 1 Target Retirement Date Investment Plans 2 Core Investments 2a Short term bond 2b Fixed income 2c Multi-asset I have tried to find good resources on understanding the core investment tier, but most of it is hard to grasp the concise procon list to each option. Do you have any resources or suggestions on when to look to better understand my 401k investment options? Thanks!Edit: formattingEdit2: more formatting  <response>: It really depends on how much money you think youll need to live on in retirement, more than whether youll increase in tax bracket while youre still working.At that income level, I would recommend a traditional 401k unless you think youll need a lot more than 110kyr in retirement.Id also stick with the target retirement date plan. Its a set it and forget it option that typically yields decent returns, and it will auto-adjust its holdings as you get older will shift more towards bonds and less risky investments as you get closer to retirement.
