American Century is one option among many, not objectively the best

Whether American Century Investments is the best mutual fund manager depends entirely on what you need from a fund — your investment timeline, how much risk you can tolerate, what you're willing to pay in fees, and whether you want active management or index tracking. American Century runs both actively managed funds (where a team picks stocks) and index funds, and their performance varies by fund and by time period. Some of their funds have beaten their benchmarks; others have underperformed. The same is true for every other major fund company.

No fund manager is best for everyone. Vanguard, Fidelity, Schwab, T. Rowe Price, and American Century all serve millions of investors, and each has strengths in different areas. The question to ask is not which company is best overall, but which fund within American Century (or elsewhere) matches your specific situation.

Key Takeaways

  • American Century offers both actively managed funds and index funds, so performance depends on which specific fund you choose, not the company name alone.
  • Fund performance is measured against a benchmark for that fund type, and past performance does not predict future results — even funds that beat their benchmark in one decade may lag in the next.
  • Expense ratios (the annual fee you pay) vary widely within American Century's lineup and across the industry, and lower fees often matter more to long-term returns than manager skill.
  • American Century is owned by Dimensional Fund Advisors, a private firm, while Vanguard is owned by its funds and Fidelity is privately held by the Johnson family — ownership structure affects how fees are set.
  • The best fund for you depends on your goals, time horizon, and risk tolerance, not on which company has the best reputation.

How to compare American Century funds to competitors

Start by identifying the specific fund you're considering, not just the company. American Century offers dozens of funds across different categories: growth, value, international, bonds, and target-date funds. Each competes against a different benchmark. The American Century Growth Fund competes against the S&P 500; the American Century Emerging Markets Fund competes against an emerging markets index. You cannot say "American Century is better" without specifying which fund and which benchmark.

Once you know the fund, look up its expense ratio — the percentage of your investment you pay annually in fees. American Century's expense ratios range from around 0.4% to 1.2% depending on the fund. Compare that directly to the expense ratio of a competitor's fund in the same category. Over 20 years, a difference of 0.5% per year compounds significantly. A fund charging 0.6% will leave you with substantially more money than one charging 1.1%, even if both beat their benchmark by the same amount.

Check the fund's performance against its stated benchmark over the past 1, 3, 5, and 10 years. You can find this on Morningstar, the fund company's own website, or your brokerage. Look at multiple time periods because a fund that led over three years may have lagged over ten. This tells you whether the fund's strategy has worked recently and whether it has worked over a longer cycle.

What American Century does well and where it falls short

American Century has a reputation for disciplined stock-picking in growth and emerging markets categories. Several of their actively managed growth funds have outperformed the S&P 500 over long periods, which is genuinely difficult — most active managers do not beat their benchmark after fees. Their target-date funds are also well-regarded and widely available through 401(k) plans.

Where American Century is not necessarily better: if you want the lowest possible fees, index funds from Vanguard or Fidelity often cost less. Vanguard's index funds typically charge 0.03% to 0.10% annually, while American Century's index funds charge 0.25% to 0.50%. If you want a broad, simple portfolio and do not believe active managers can beat the market consistently, a cheaper index fund will serve you better. If you want access to a wide range of bond funds or international options, Vanguard and Fidelity have deeper lineups.

American Century also does not have the brand recognition or the massive scale of Vanguard or Fidelity, which means fewer employers offer their funds in 401(k) plans. If your workplace plan includes American Century funds, that's convenient; if not, you'd have to open a separate brokerage account to invest with them.

The role of fees in long-term returns

A fund manager's skill matters less than most investors think. Research consistently shows that after accounting for fees, most active managers underperform their benchmark over 10+ years. This is not because they lack skill; it's because beating the market by enough to cover your fees is statistically very hard. The funds that do beat their benchmark often do so by 1% to 2% per year — which is real money, but not may provide to continue.

Fees, by contrast, are may provide. If you pay 1% per year, you lose 1% per year, no matter what the market does. Over 30 years, the difference between a 0.5% fee and a 1.0% fee can reduce your final balance by 15% to 20%, assuming equal performance before fees. This is why fee comparison matters as much as performance comparison.

American Century's fees are middle-of-the-road. They're higher than Vanguard's index funds but lower than many actively managed funds from smaller firms. Whether that trade-off is worth it depends on whether you believe their active managers will beat their benchmarks going forward — and that's a bet, not a certainty.

Ownership structure and how it affects your costs

American Century is owned by Dimensional Fund Advisors, a private investment firm. Vanguard is owned by its own funds (meaning investors own the company). Fidelity is privately held by the Johnson family. This ownership structure affects how fees are set and whether the company has incentive to keep them low.

Vanguard's structure means the company has direct incentive to lower fees — doing so benefits the fund owners, who are the same people who own Vanguard. Fidelity and American Century are not owned by their investors, so they can charge higher fees without that structural pressure. This does not mean American Century is dishonest or overpriced, but it does mean you should compare their fees to Vanguard's as a baseline. If American Century's fund charges 0.8% and Vanguard's equivalent index fund charges 0.05%, you're paying for active management. That may be worth it if the fund has beaten its benchmark, but you should know what you're paying for.

How to decide if American Century is right for you

American Century is a reasonable choice if: you believe active management can add value (and you have evidence from the specific fund's track record), you want exposure to growth or emerging markets and their funds have performed well in your time horizon, or your employer's 401(k) plan offers American Century funds and you like the options available.

American Century is probably not the best choice if: you want the lowest possible fees and are comfortable with index investing, you need a very broad range of fund options and your brokerage doesn't carry American Century, or you're building a simple portfolio and don't want to research individual managers.

The practical step: pick the specific fund you're considering, look up its expense ratio and its performance over the past 5 and 10 years, then compare those numbers directly to 2 or 3 competitor funds in the same category. Do not compare American Century Growth to Vanguard's Emerging Markets fund — compare apples to apples. If American Century's fund has lower fees and better performance, it's a strong candidate. If it has higher fees and similar performance, the cheaper option is probably better.

Frequently Asked Questions

Does American Century beat the S&P 500?

Some of their actively managed funds have beaten the S&P 500 over certain periods, but not all, and past performance does not predict future results. Their American Century Growth Fund has outperformed the S&P 500 over the past 10 years, but this varies by fund and by time period. Check the specific fund's performance on Morningstar or the company's website.

Are American Century funds available in my 401(k)?

That depends on your employer's plan. American Century is available in many large employer plans but not all. Check your plan's fund list or ask your benefits administrator. If American Century is not in your plan, you can still invest with them through an individual brokerage account.

How do American Century's fees compare to Vanguard?

Vanguard's index funds typically cost 0.03% to 0.10% per year, while American Century's index funds cost 0.25% to 0.50%. American Century's actively managed funds cost 0.5% to 1.2%. If you want the lowest fees, Vanguard's index funds are cheaper. If you want active management, compare American Century's fees and performance directly to other active managers.

What if I want to invest with American Century but I'm not sure which fund to pick?

Start with your time horizon and risk tolerance. If you're investing for retirement 30+ years away, a growth or emerging markets fund may fit. If you're closer to retirement, a balanced or target-date fund may be better. Look at the fund's past performance and expense ratio, then compare to one competitor in the same category. Choose based on fees and track record, not company reputation.

Can I lose money investing in an American Century mutual fund?

Yes. Mutual funds are not may provide. Stock funds can drop 20%, 30%, or more in a down market. Bond funds can lose value if interest rates rise. The longer your time horizon, the more you can tolerate short-term losses, but losses are always possible. Never invest money you'll need within 5 years in a stock fund.
