What a sum of money in one year is worth in another, using each country's own consumer price index. The figures come from the World Bank, the page says when they were retrieved, and a country or a year the source does not cover is refused rather than estimated.
How it works
An amount is multiplied by the ratio of two index values: the index in the later year divided by the index in the earlier one. That is the whole calculation. The base year of the index does not matter, because it cancels in the ratio.
The average annual rate is the same ratio spread evenly over the years between, which is a compound rate rather than the total divided by the number of years. Prices compound, so an average that did not would be the wrong kind of average.
A consumer price index measures a basket of goods in one country. It is a good answer to "what would this have cost" and a poorer one to "what was this worth to someone", because the basket, the goods in it and how people live all change over decades.
Frequently asked questions
Why is my country not in the list?
Because the source has no price index for it. Argentina is the one that surprises people: the World Bank publishes no consumer price index series for it in this indicator at all. A country with no data is left out rather than offered and then failing, and the list shows the years each country covers so you can see before you ask.
Why was my range refused?
Either one of the years is outside what the source measured for that country, or there is a gap between them. Iraq has no index between 1979 and 1989, so a calculation from 1960 to today would be asserting something about eleven years nobody measured. The message tells you which unbroken runs of years you can use instead.
Which currency is the amount in?
The country's own, whichever that is — the index is a domestic one, so an amount for Switzerland is in francs and one for Japan is in yen. No conversion between currencies happens here. Watch out for countries that redenominated: the index runs continuously through a currency reform, so an old amount comes out in new units and the figure needs reading with that in mind.
How current are the figures?
The page shows the date they were retrieved and the date the source last updated them. The index is annual, so the most recent complete year is the furthest it can go — this is not a tool for "since last March". The data is a snapshot in the repository rather than a live call, so nothing about your visit reaches the World Bank.
Is this the official inflation rate?
It is the World Bank's series, which is compiled from what national statistics offices publish. For a figure to quote in a contract or a dispute, go to your own national statistics office: they publish more often, usually further back, and theirs is the number that counts locally. This page is for getting a sense of scale across a lot of countries at once.
Good to know
- The figures are a dated snapshot, not a live feed. The date they were retrieved is on this page, and a price index goes out of date on its own — so read that date as part of the answer.
- The index is annual. A month-to-month question cannot be answered from it, and no attempt is made to interpolate one.
- Nothing is estimated, extended or interpolated. Where the source stops, this page stops.
