How it works
Inflation compounds like interest. If prices rise by a steady rate each year, goods that cost one amount today cost amount x (1 + rate)^years after that many years.
The other side of it is buying power: money held in cash for that long buys only amount / (1 + rate)^years of today's goods.
Real inflation changes from year to year and differs between goods, so a single steady rate is an illustration. Use it to see the size of the effect, not to predict a price.
Common mistakes
- Ignoring inflation when judging a savings rate: a 3% account in a 3% inflation year gains nothing in real terms.
- Using the average inflation of one country for a price in another.
- Assuming every price rises at the headline rate; housing, food and electronics move differently.
