Inflation stood at 3.4 percent in September, according to flash estimate
The inflation rate stood at 3.4 percent in August 2026, according to the flash estimate of Statistics Netherlands (CBS). The flash estimate is based on source data that is not yet complete. Inflation in August 2026 was 3.3 percent.
Inflation is measured every month as the year-on-year change in the Consumer Price Index (CPI). The CPI also provides an insight into how prices changed compared to the previous month. According to the flash estimate, consumer prices rose by 0.1 percent in September 2025 relative to August 2025.
The regular consumer price index (CPI) figures will be published on 13 October.

Short-term price trends
According to the flash estimate, consumer prices rose by 0.1 percent in September 2025 relative to August 2025. Over the past ten years, prices in September have been the same as those in August, on average. It should be noted that when comparing two consecutive months, seasonal influences must be taken into account. For example, the average price change for clothing is lower during sales periods. However, these lower prices are temporary rather than structural.
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 development of all categories in the CPI will be published on 13 October.
| September 2026 (%) | August 2026 (%) | |
|---|---|---|
| All items | 3.4 | 3.3 |
| Food, beverages and tobacco | -1.2 | -0.5 |
| Energy including motor fuels | 13.9 | 11.6 |
| Non-energy industrial goods | 1.5 | 1.4 |
| Services | 3.9 | 3.7 |
| Consumption abroad | 7.7 | 7.4 |
HICP flash estimate
Statistics Netherlands 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 3.0 percent in September. In August, the HICP inflation rate was 2.8 percent.
New base year for CPI with effect from 2026
With effect from this year, 2026, a new base year will be used for the CPI and the HICP. The base year will change from 2015=100 to 2025=100. Further information on this change is available in the methodology document: Consumer price index from 2026.
