When I was a kid a 3 Musketeers bar cost 30 cents at my favorite shop, North End Pharmacy. The last time that I saw one in a gas station it cost $1.39. That’s ridiculous! What happened? Inflation, happened.

I like to use that candy bar example whenever I begin to explain inflation to kids. t’s a product they’re familiar with and usually have a good sense of its current value. If you want to come up with other examples or have students explore the impact of inflation on their own, take a look at the new Inflation Calculator created by Involve.me.

The Inflation Calculator lets you enter a dollar amount then select two years to see the change in the value of the original dollar amount over time. Watch this short video to see how it works.
