How to invest? Americans don't know some basics.

Americans lack the knowledge and confidence to invest, a new survey finds. Here are some resources to get you started in investing.

In a recent survey, more than half of the current investors said low prices were most important in picking an online broker, but only 1 in 10 compared costs across accounts when making their choice.

Are you a knowledgeable investor? Try this quiz:

  1. What kind of account must be opened in order to trade stocks online? 
  2. What will the average household in pay total 401(k) fees over a lifetime? a) $10,000; b) $50,000; c) more than $150,000? 
  3. What's the most important factor for most Americans picking an online broker?

If you said: brokerage account, more than $150,000, and low prices, then congratulations. You're far ahead of most Americans, whose grasp of investing is rudimentary.

The three questions above caused the most problems for the 869 adults in a new investment literacy survey conducted by InvestingNerd. For example: 4 in 5 couldn’t identify a brokerage account; 9 in 10 severely underestimated how much a 401(k) would cost them (because beyond the stated fees are the trading costs, which also sap returns); and while over half of the current investors in the survey said low prices were most important to them in picking an online broker, only 1 in 10 actually took the time to compare costs across accounts when making their choice.

No wonder so many Americans don’t invest! They lack the knowledge and confidence to feel they are doing a good job at it.

Over a quarter of non-investing respondents said they avoided investing altogether because of either uncertainty on how to get started (13.6 percent) or not wanting to risk losing money (12.8 percent). A full 39.3 percent said they did not invest because they do not have enough money to do so.

Investing is a key pillar of a strong personal finance foundation. These results all point to one thing – knowing how to get started, and what to look for once you are ready to invest – is half the battle.

So where should you look for help?  Here are three places where people can get started learning about basic investing concepts:
