The S&P Global FinLit Survey covers numeracy, interest compounding, inflation and risk diversification. These topics are useful starting points, rather than a complete test of someone's ability to manage money.
The questions the research actually uses
Three questions, developed by Annamaria Lusardi and Olivia Mitchell, became the standard measure and have been run in dozens of countries.
Compounding. With $100 in an account paying 2% a year, after five years you would have more than $102, exactly $102, or less than $102? The answer is more, because interest earns interest.
Inflation. If your account pays 1% a year and inflation runs at 2%, after a year you could buy more, the same, or less than today? Less. The balance grows and its purchasing power shrinks.
Diversification. Is buying a single company's stock usually safer than buying a fund holding many stocks? No. Spreading holdings reduces the risk specific to any one company.
The questions look almost insultingly simple, which is the point. The share of adults answering all three correctly sits below half in most national samples, and the pattern is consistent across countries.
The two concepts that cost the most money
Compound interest matters in both directions and people generally understand it better as a benefit than as a cost. The Rule of 72 makes it concrete: divide 72 by an annual rate to get the years to double. At 7% a sum doubles in about a decade. The same arithmetic runs on debt, which is why a credit card at 22% doubles what you owe in a little over three years if nothing is repaid.
Inflation can reduce purchasing power even when a balance grows. If an account pays 1% while prices rise 3%, the real annual return is approximately minus 2%, before fees and taxes. Check the starting balance and assumptions when comparing percentages.
Explore compounding and inflation with basic arithmetic and a calculator. These concepts involve more than subtraction.
What low financial literacy is associated with
The research finds consistent associations, though causation is difficult to establish and the studies are mostly observational.
Lower measured literacy tracks with higher-cost borrowing, less retirement planning, less stock market participation, and a greater likelihood of paying avoidable fees. The retirement planning finding is one of the most consistent: people who answer the three questions correctly are substantially more likely to have thought concretely about retirement, and planning is one of the strongest predictors of what people end up with.
Survey results can vary by age, gender, education, income and country. Group averages do not establish any individual's knowledge, and an observed gap does not by itself identify its cause. Check the sample and measurement before generalizing.
Does financial education help
An educational resource can explain concepts, but completing a course or earning a quiz score does not guarantee better financial outcomes. Look for opportunities to apply what you learn and review the consequences.
Before a financial decision, check current local rules, fees, risks and any relevant professional advice. A hypothetical exercise can help you understand a calculation; it cannot choose an appropriate product or strategy for your circumstances.
This is not an argument against knowing the material. Understanding compounding and inflation is genuinely useful, and it is cheap to acquire. It is an argument against expecting knowledge alone to fix behavior, since the gap between knowing high-interest debt should be cleared first and actually clearing it is where the money goes.

Questions people also ask
What is the Rule of 72?
A shortcut for compound growth: divide 72 by an annual percentage rate to estimate the years until a sum doubles. At 6% it takes about 12 years, at 9% about 8. It works on debt exactly as it works on investments, which is the more useful application for most people.
Is financial literacy the same as being good with money?
No. Literacy is understanding the concepts; behavior is what you do. The two correlate and the gap between them is wide, which is why interventions that change defaults tend to outperform interventions that change knowledge.
