How do we calculate the index?
- A basket that renews every month
- The basket holds every product on sale at a Belgian online shop. Within a month it stays the same, so we measure price changes, not a changing range. On the 1st of every month a new basket starts: new products and shops come in, products that are gone leave. The new basket carries on from the old one's level, the way statistics offices do it, so the renewal itself doesn't move the index. When a big shop arrives, a new basket starts right away. The index starts on 1 September 2026.
- The same shops
- For each product we only compare the shops that already sold it when the basket started. If another shop offers it cheaper later, the index doesn't drop: that is a new offer, not a price cut. That shop counts from the next basket.
- The lowest price
- For each product and each day, the lowest price at those shops counts: the price you actually pay.
- A geometric mean
- The index is the geometric mean of all price relatives (today's price divided by the price when the basket started), times 100. That is the Jevons method statistics offices use for indices like this. A price that rises and falls back doesn't quietly push the index up.
- Outliers
- A price more than four times higher or lower than when the basket started is left out. That is nearly always an error in a product feed, not a real price change. Categories with fewer than 10 products are not shown.
Frequently asked questions
- How often is the index updated?
- Every morning, after the daily price update from all shops. A day we already published is never recalculated: a figure shown here stays.
- Why does this differ from Statbel's inflation figure?
- Statbel measures a broad basket of everything households spend on, including services, energy and food. The Procently Price Index only follows products sold online, mostly electronics and home appliances.
- Which online shops count?
- Every Belgian online shop whose prices we collect daily. For each product, the shops that sold it when the current basket started count. A new shop counts from the next month.
- Does the index say anything about Black Friday?
- That's why we track it. If prices go up in the weeks before Black Friday, you'll see it here. To check a single product, use the Black Friday check.
