The inflation rate stood at 2.8 percent in August 2025, according to the flash estimate of Statistics Netherlands (CBS). The flash estimate is based on source data that is not yet complete. Inflation in July was 2.9 percent.

Inflation is measured every month as the change in the Consumer Price Index (CPI) relative to the same month of the previous year. The CPI also provides an insight into how prices changed compared to the previous month. According to the flash estimate, consumer prices rose by 0.2 percent in August 2025 relative to July 2025.

The regular consumer price index (CPI) figures for August will be released on 9 September.

Short-term price trends

According to the flash estimate, consumer prices rose by 0.2 percent in August 2025 relative to July 2025. It should be noted that when comparing two different months in the same year, seasonal influences must be taken into account. For example, airline tickets are more expensive in holiday months than outside the holiday season. These higher prices are temporary rather than structural, however.

Price changes across various product groups

In addition to the inflation rate, CBS also publishes price changes for a number of product groups as part of its flash estimate. These product groups are aggregations of spending categories for a particular theme, such as ‘all services’. The price changes for all categories in the CPI will be published on 9 September.


HICP flash estimate

CBS publishes two different figures for inflation. One is based on the Consumer Price Index (CPI) and the other on the European Harmonised Index of Consumer Prices (HICP). According to the HICP flash estimate, inflation stood at 2.4 percent in August. In July, the HICP inflation rate was 2.5 percent.

In the case of the Netherlands, the main difference between the CPI and the HICP is that the HICP does not take into account costs related to home ownership, unlike the CPI. In the CPI, these costs are calculated based on changes in rents for housing. This is not the only difference, however. The differences are explained in greater detail in the article linked below.

New base year CPI with effect from 2026

With effect from 2026, a new base year will be used for the CPI and the HICP, from 2015=100 to 2025=100. It is worth noting that these changes will not affect inflation figures that have already been published. At the same time, the classification of goods and services will be updated, in order to reflect changes in consumption patterns better. With effect from 2026, the CPI will also be brought more into line with the HICP. The first figures based on the new series with 2025 as the base year will be published in early February 2026.
