🎯 Goal: Understand idle cash loses to inflation; investing in assets that grow over time protects purchasing power.
Idle cash loses value to inflation. To protect purchasing power, people invest in assets with expected return above inflation (stocks, funds, real estate) for the long run.
Let’s explore
🎈
Inflation slowly cuts cash’s purchasing power each year.
📈
To not "lose" to inflation, you need a positive real return (return > inflation).
🛡️
Diversifying and long-term investing improve the chance of beating inflation.
Practice activity
🧮 Deposit at 4%/year, inflation 6%/year — does real purchasing power rise or fall?
Worked example: 4% return but 6% inflation → real ≈ 4 − 6 = −2%: the number grows but buys less. To beat inflation, you need a channel expected above 6% (accepting more risk).

🎯 Real-life mission
Compare a savings rate with current inflation and compute the real return.
