The Personal Finance Index is a long-running survey that measures financial knowledge. U.S. consumers can answer only around 50% of the questions correctly.
This knowledge gap creates real problems. People with low financial literacy are more likely to live paycheck to paycheck and less likely to have emergency savings. The issue hits certain groups particularly hard, with women, Gen Z, and Black and Hispanic Americans typically scoring lower on financial literacy tests.
“Financial literacy is very low,” says Annamaria Lusardi, a Stanford finance professor who helped create the P-Fin Index, “not just in the U.S., but around the world. People just do not have those basics, even though they’ve made a lot of financial decisions. We can and we should find ways to improve it. The world is too complex to rely on only the knowledge people currently have.”
A revolutionary approach
More schools now offer financial literacy courses, but this approach misses millions of adults who have already graduated. It may also bypass young people who do not finish high school or attend college. For these groups, acquiring financial knowledge later in life can be challenging.
Lusardi teamed up with researchers from North Carolina State University, George Washington University, and the University of Pennsylvania to test whether simple narratives could effectively teach financial concepts to adults. They focused on Americans aged 45 and older, who had made significant financial decisions but likely had little formal financial education.
The team crafted three two-minute stories covering fundamental concepts:
- Compound interest story: Newlyweds received $5,000 in wedding gifts and had to decide what to do with the money. After learning about the Rule of 72, a simple method for calculating how long it takes investments to double, they chose to invest immediately.
- Inflation story: Lisa discovered how much prices had changed by tracking the cost of a plaid shirt over time, inspiring her to save more aggressively.
- Risk diversification story: Kate and Sam debated how to invest money from selling their car, discussing long-term stock market investing and the importance of spreading risk across different assets.

Remarkable results
The stories worked surprisingly well. Participants who read the risk diversification story were 17 to 18 percentage points more likely to answer related questions correctly than those who read nothing. The compound interest story boosted accuracy by up to 17 percentage points on certain questions, while the inflation story improved scores by 6 to 8 percentage points.
Lusardi explained that stories are memorable, tend to dispel the idea that finance is complex, and help people to understand concepts.
Eight months later, people who had read the risk diversification story retained nearly half their newfound knowledge. Retention was not as strong for the other topics, which involved trickier mental math. However, the inflation story readers spent more time considering inflation-related questions, suggesting genuine engagement with the concept.
The approach worked especially well for people with lower education and income levels, potentially democratizing access to financial literacy.
Building financial confidence through stories
Stanford’s research offers a hopeful message: improving financial literacy may not require formal courses or dense textbooks. Sometimes, it starts with something much simpler — a well-told story.
Narratives help people connect abstract concepts to real life. That makes the ideas easier to grasp, remember, and apply. The study found this method especially effective for people with lower education or income levels, a group often overlooked by traditional financial education.
- Banks can use stories to explain products in everyday language.
- Employers can build story-based learning into financial wellness programs.
- Families can turn money talks into relatable examples.
- Community groups can share short narratives to spark financial awareness.
“In finance, ignorance is not bliss,” says Lusardi. “The fact that people don’t understand the basics is a huge problem, and we are going to pay the costs of financial illiteracy. We just have to decide how. Do we want to pay for prevention, or do we want to pay for the cure?”
Stories are easier to remember than complex concepts. The trick is to embed the concepts in the stories. In a financial world where knowledge is power, keeping simple stories in mind can help you remember what matters most when your money is at stake.
