A recent ING survey found that most respondents have only basic knowledge of finance, meaning that even if they understand the simple rules of finance like emergency funds and saving for retirement, they find it hard to practice them. In fact, less than 60 percent even had a retirement plan. The survey also found that emotional health directly corresponded with financial literacy; the more knowledgeable about their finances people are the happier they feel. Do you think you are financially literate, or are you still learning? Take this FINRA Financial Quiz and test your knowledge.
