What causes inflation and how is it measured?

Inflation is when money loses its power, like when your favorite candy bar gets more expensive every week.

Imagine you have a piggy bank full of coins. At first, those coins buy you one big ice cream cone. But over time, the shop owner decides to charge more for that same ice cream cone, maybe two coins instead of one. That’s inflation, prices go up, and your money doesn’t stretch as far.

Think of the economy like a bakery. If everyone wants a cookie but there are only a few ovens baking them, cookies become scarce and cost more. That's one way inflation happens, when demand goes up faster than supply.

Sometimes, bakers also raise prices because ingredients got more expensive, that’s another cause of inflation. It’s like if flour suddenly costs twice as much, so the cookie price has to go up too.

People use something called a consumer price index (CPI). It's like keeping track of how much things cost over time. Imagine you have a list of your favorite snacks, candy bars, ice cream, cookies, and every month you check how much they cost. If the total goes up, that means inflation is happening!

Sometimes adults use fancy calculators to figure this out, but it's really just counting and comparing, like when you count your coins before buying something.
