The current monthly consumer price index CPI₂₀₂₅ is calculated from the monthly consumer price index CPI₂₀₂₄ of the year 2024 and the inflation rate I of the current month:

CPI = (I / 100 + 1) * CPI₂₀₂₄.

The annual value for the consumer price index CPI 2025 is calculated from the average of the monthly values resulting from the inflation rates already published. The annual value for the CPI 2024 consumer price index is calculated from the average of the corresponding monthly values. The annual value I for the inflation rate is calculated from the two annual values of the consumer price index CPI₂₀₂₅ and CPI₂₀₂₄:

I = (CPI₂₀₂₅ / CPI₂₀₂₄ - 1) * 100.

According to this calculation, the provisional inflation rate for 2025 would be 2,2 %.
