Imagine your child standing in front of the pick-and-mix stand at the local shop. They have their trusty £1 coin clutched in their hand. Last year, that pound bought them a full bag of sweets. Today, the same pound only fills the bag halfway.
That “shrinking bag” is the simplest way to explain inflation to a child.
At its heart, inflation isn’t about complex economic charts; it’s about the “purchasing power” of our money. For a seven-year-old, understanding that prices can change over time is a foundational lesson in financial literacy. Here is how to explain it using everyday magic.

The “Ice Cream” Analogy
Ask your child to imagine an ice cream cone. If everyone in the world suddenly had ten times more money, they would all want more ice cream. But if the ice cream man only has the same amount of vanilla and chocolate, he has to raise the price so he doesn’t run out. This is “too much money chasing too few goods.”
Why “Saving Under the Mattress” Doesn’t Work
Explain that if we hide our gold coins in a box for ten years, they might only buy half as much bread as they do today. In The Financial Fairy Tales, we talk about sowing seeds. By investing, we aim to grow our money faster than the prices in the shops are rising.
A Simple Game to Try
Next time you are at the supermarket, point out a “special offer” or a price increase. Ask your child: “If this bread costs more today than it did last month, do we need to find a way to make our money ‘stronger’?”
The Lesson of Resilience
In The Financial Fairy Tales: Activity Book, we explore how being smart with our “gold coins” means planning for the future. Understanding inflation isn’t about fear; it’s about being prepared. It teaches children that while we can’t always control the prices in the shops, we can control our habits and our education.
