Inflation
Age 10+When things slowly cost more over time. The candy bar that cost $1 five years ago might cost $1.25 now.
At a glance
Inflation is the slow rise in prices over time. The dollar today buys slightly less than the dollar a year ago, and noticeably less than the dollar a decade ago. The annual rate is usually around 2-4% in the US but can spike higher in some years. Inflation is invisible day-to-day but enormous over decades, which is why money sitting in cash quietly loses value year after year.
Example sentence
"That's why the same toy is more expensive than it was when I was a kid — inflation."
Why this matters for kids
Inflation is the silent reason why money in a checking account or under a mattress slowly becomes worth less, even though the number doesn't change. A kid who understands this concept by twelve has the foundation for the most important adult financial decision: why investing isn't a luxury but a defense against inflation. Cash sitting in a non-interest-bearing account at 0% return loses to inflation every year — at 3% inflation, $1,000 today is worth $863 in real purchasing power five years from now. Money in a savings account at 4% APY gains a little against inflation. Money in a diversified investment portfolio averaging 7-10% real return grows wealth meaningfully over time. The rate matters; the alternative isn't no risk, it's the slow guaranteed loss of inflation. Kids who internalise this don't default to "saving is enough" — they learn that long-term wealth building requires beating inflation, which means investing.
How to teach it
Find a photo or ad of something from your childhood with a clearly visible price — a gallon of gas, a comic book, a movie ticket, a McDonald's burger, a dozen eggs. Compare to today's price for the same thing. Do the math of how much more expensive it is, and crucially the rate per year. Show them the BLS Consumer Price Index calculator (free online) — type in $100 in 1995, see what it would equal today. The number is around $200, which means money lost half its purchasing power in 30 years just by sitting still. For older kids, contrast this with what $100 invested in an S&P 500 index fund in 1995 would be worth today (around $1,500). That single comparison — same starting amount, two completely different outcomes — is one of the most powerful financial visuals a teen can see. Repeat the exercise occasionally with different numbers and time spans.
Common misconceptions
- Inflation only matters in extreme cases. Even at "normal" 3% inflation, money loses about half its value over 25 years. The drift is constant.
- Inflation is always bad. Mild inflation is actually preferred over zero or negative inflation; it nudges economic activity. Crippling inflation is bad. Reading the news, kids should know the difference.
- A higher savings rate beats inflation. It depends on the rate. A 4% APY savings account barely keeps up with 3% inflation. A 0.01% checking account is losing.
