Everyone experiences inflation differently, and now the European Central Bank measures it. Even as official indices show price pressures easing, many people still face high day-to-day costs. To bridge the gap between the published rate and lived experience, the ECB has launched an interactive tool that estimates each household’s “personal inflation” from real spending patterns, from supermarket bills and fuel to rent and services.
The personal inflation calculator builds on your own “basket” of expenses. Users select their country and enter monthly spending across 12 core categories of goods and services, or drill down into sub-categories for more precision. The tool then computes a personal index and compares it with the national HICP and the euro-area average. Infrequent purchases, such as a car, are converted into a monthly cost over the years of use (for example, six years equals 72 months). At the end, you see the official inflation rate for the period, your personal inflation rate, and the categories driving your result.
The app automatically pulls the latest price data from the ECB’s database and does not store personal information. Your personal inflation is calculated as a weighted average of price changes across the items you buy, using the share each category represents in your basket. It is an informed estimate, not a precise measurement, since perfect accuracy would require item-level data for everything you purchased today and a year ago.
Why your inflation can feel higher
The ECB pairs the calculator with plain-language explainers on what inflation is, how it is measured, and why it often feels higher than the headline number. Interactive visuals show how the price basket is constructed, which categories carry the most weight, and why two households in the same city may experience very different inflation depending on their mix of spending.
Users can compute their own personal rate via the ECB’s official calculator and see which costs are doing the most damage in their monthly budget.
