Contributions
You choose how much of your eligible pay to contribute, subject to plan rules and applicable IRS limits. Check whether your contribution rate captures the full employer match available under your plan.
401k Calculator & Guide
Your 401(k) is more than a retirement savings account. The investments you choose, the costs you pay, and the risks you take can all influence your long-term results. Learn the basics of investing your workplace retirement savings and how to evaluate the options available in your plan.
Learn the Basics → Explore Asset AllocationA 401(k) is an employer-sponsored retirement plan that lets eligible employees contribute part of their pay toward retirement. Depending on the plan, an employer may also contribute matching or other amounts. Your contributions are then invested in the options available through the plan, according to the elections you make.
Your account's future value depends on several factors, including contributions, employer contributions, investment performance, fees, and time. Returns are not guaranteed, and your balance can fall as well as rise.

Your plan may offer mutual funds, target-date funds, collective investment trusts, or other options. Availability varies by employer and plan.
Investment returns can generate additional returns over time. Compounding can help build wealth, but actual growth is uncertain and losses are possible.
Not every 401(k) offers the same investments. Learn what each category generally does, then compare the specific options in your plan.
Invest in shares of companies. Stock funds can offer long-term growth potential, but prices fluctuate and losses can be substantial, particularly over short periods.
Invest in bonds or other debt securities. They can serve a different role from stocks, but still carry risks such as interest-rate, credit, and inflation risk.
Seek to track a market index. They often offer broad exposure and may have relatively low operating expenses, although costs and strategies vary.
Use an approximate retirement year to guide an investment mix that generally becomes more conservative over time. Funds with the same target year can differ significantly.
Combine asset classes in one investment. Check the fund's allocation, objective, costs, and whether it automatically adjusts its holdings.
Some plans offer options intended to emphasize principal stability. Their guarantees, restrictions, returns, and risks depend on the specific product and contract.
Some plans also provide brokerage windows or collective investment trusts. Read the plan documents and investment-specific disclosures to understand eligibility, expenses, restrictions, and risks.
Diversification means spreading investments across different assets, sectors, companies, or regions rather than relying heavily on a single holding. It can help manage concentration risk, although it cannot eliminate investment risk or guarantee profits.
A portfolio invested in a range of assets may be less dependent on the performance of one company, sector, or market. Broad funds can help, depending on what they hold.
Owning several funds does not necessarily mean you are diversified. Different funds may hold many of the same companies or assets.
Your time horizon, financial circumstances, and ability to tolerate losses can affect how you think about investment risk. There is no universal allocation for every investor.
Asset values change at different rates, which can cause your portfolio to drift away from its intended mix. Rebalancing brings it closer to a chosen allocation.
Stocks generally offer greater growth potential alongside greater volatility. Bonds can behave differently but are not risk-free. Cash-like options may offer stability while carrying inflation and opportunity costs. The right balance depends on your goals and circumstances.

Your example allocates 100% of the portfolio. Consider the role and risk of each asset class before making actual investment choices.
The example profiles are arbitrary educational illustrations, not age-based rules. Retirement timing alone does not determine an appropriate investment mix. Some investors may prefer different allocations depending on goals, risk tolerance, other assets, and financial needs.

| Risk | What conditions could cause losses or lower returns? | Risk disclosures and investment strategy |

Use this checklist to organize your review of your workplace retirement account.
Review your plan documents before changing investments. If you need individualized guidance, consider consulting a qualified financial professional who understands your circumstances.
Some participants make contributions but do not select investments. Check how your plan handles contributions and whether your account is invested according to your elections.
A fund that recently outperformed may not continue to do so. Review objectives, risks, costs, and longer-term context rather than relying on recent returns.
Small recurring expenses can affect long-term results. Review both investment expense ratios and separate plan-level fees.
Large market declines can be difficult to withstand. Understand the potential losses associated with your investments before choosing an allocation.
Several funds may hold similar assets. Review underlying holdings and exposures to understand how your portfolio is actually diversified.
Your needs, contributions, and investments can change. Periodically check whether your plan still fits your goals and whether rebalancing is appropriate.

There is no single investment suitable for everyone. Your plan's options, time horizon, risk tolerance, other assets, and financial goals all matter. Review each investment's objective, costs, and risks. A target-date fund may offer a diversified, professionally managed approach, but its design and suitability vary.
A target-date fund can simplify investing by combining asset classes and adjusting its mix over time. However, funds with the same target year can have different allocations, fees, and risk levels. Read the fund's materials before selecting one.
An all-stock portfolio can experience substantial declines. Whether that risk fits your circumstances depends on your goals, time horizon, ability to tolerate losses, and other resources. A long time horizon does not automatically make an all-stock allocation appropriate.
No. Index funds often have lower expenses, but investment approaches differ. Compare similar objectives, fees, diversification, risks, and performance relative to relevant benchmarks. No approach guarantees better results.
Consider reviewing your investments periodically and when your circumstances, plan options, or goals change. Rebalancing frequency depends on your approach and plan features; frequent changes are not automatically beneficial.
Rebalancing means bringing a portfolio back toward its intended asset allocation after market movements change the relative weights of investments. Some plans or target-date funds may offer automatic features. Review applicable costs and tax or plan considerations.
Most market-based 401(k) investments do not guarantee returns, and you can lose money. Certain plan options may have specific guarantees or principal-protection features, subject to their terms. Read the relevant documentation carefully.
Investment expenses reduce returns available to compound in your account. Over long periods, differences in recurring fees can produce meaningful differences in hypothetical outcomes. Use our 401(k) investment fees guide to learn about common costs.
Many plans allow participants to change future contribution elections and exchange existing investments, subject to plan rules and any applicable restrictions. Review your plan's procedures and understand the implications before making changes.
Understand your investment options, compare fees, and review your portfolio with a clear view of risk and long-term goals.
