Basic InvestorU.S. Module 01 · Know the container
Compare the plan before choosing the investment.
A 401(k), 403(b), 457, traditional IRA or Roth IRA is a set of rules around saving and withdrawing money. The investments held inside the account still need their own review.
A practical comparison
Ask what the plan lets you do.
- Eligibility: Who can participate, and when?
- Contributions: What can the employee and employer contribute, and what limits apply?
- Employer money: Is there a match, nonelective contribution or vesting schedule?
- Investments: Which choices, fees, restrictions and advice services are available?
- Access: What happens if you change jobs, need a distribution or roll funds over?
The summary plan description, fee disclosures and investment options answer questions that a product name cannot. Current limits and tax treatment change, so verify them with official sources.
This lesson is general education, not tax, investment, benefits or legal advice.

Do not compare labels alone.
A Roth feature, employer match or low-cost fund may be useful, but the practical decision depends on eligibility, timing, tax treatment, fees, investment choices and your ability to use the benefit. Keep the plan’s current documents with your questions and verify details before acting.
