For indexing purposes, the FSO recommends the use of the rounded index results according to the indexing table below or the CPI Inflation Calculator.

Release calendar
Contracts often link amounts to inflation by means of indexation over a certain period of time. This is intended to prevent the agreed amount from being devalued by any inflation. This is particularly important for wages, pensions, alimony or long-term contracts. The agreed amount is indexed to a constant purchasing power.
An ordinary rule of three is used to calculate an index-linked amount at any given time:
indexed amount = initial amount x final index value / initial index value
When applying the index results in connection with contractual inflation compensation, it is advisable to clearly describe the following framework conditions:
- Reference month and value of the amount to be indexed;
- Defined index base and index level in the reference month;
- indexation mechanism.
Indexing with the online calculator
With the inflation calculator you can calculate amounts indexed with the national consumer price index (e.g. alimony payments, pensions, etc.) or the inflation rate over any period of time.
