What is inflation in economics?

In economics, inflation refers to a sustained rise in the general price level, reducing purchasing power. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.

How to approach it step by step

To work with inflation confidently, compare price indices between periods to get the inflation rate. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.

Worked example

If the index rises from 100 to 106, annual inflation is 6 percent.

The mistake most learners make

Confusing a falling inflation rate with actually falling prices.
