What is inflation?

A money search that spikes whenever prices jump. This page has 50 important questions and answers. Original explainer for daily search — not a government login or live tracker.

Inflation is a general rise in prices over time — your money buys less of the same basket of goods. Central banks watch a consumer price index (CPI). A little inflation is normal in growing economies; very high inflation hurts savers and anyone on a fixed income.

Inflation is not the same as one shop’s sale ending. It is not GDP. And a pay rise that lags inflation is a real-terms cut.
