1978

In what year did the U.S. Congress create the tax provision behind the modern 401(k) retirement plan?

The 401(k) came from a little-noticed provision in that year's Revenue Act, and the first real plans appeared just a few years later.

About how much total money was held in U.S. 401(k) plans as of early 2026?

401(k)s have grown into one of the largest pools of retirement savings in the country since their 1978 creation.

0.78%, about $250 per participant

In 2011, what was the average total administrative and management fee on a typical 401(k) account?

Fees that sound small can meaningfully eat into long-term retirement returns over decades.

Questions

How does InvestorSurvey.com work?

Each question asks you to guess a real number about investing and the stock market. After you answer you see how everyone else guessed, then the real figure and where it comes from.

How is the daily round scored?

Four stats and one opinion poll. A correct guess earns 100 points plus up to 50 for speed, with a combo bonus for answers in a row. The range next to the right answer earns 40. Opinion polls earn 25 for having your say, and nailing every stat adds 150.

Where do the numbers come from?

Every stat links to its source, such as government statistics agencies, research organizations and industry groups. Figures are checked against the source before they go live.

Is it free?

Yes. Playing, streaks, badges and leaderboards are free, and your votes stay anonymous.
