The prices in PriceWiki database are submitted by web users. Most of the prices are submitted by knowledgable contributors with good intentions. The statistical credibility of our database comes from many users submitting prices for the same product and location. For large datasets the outcome will represent the actual price levels. PriceWiki uses median prices and common price ranges to inform users about price levels.

In spite of this we are aware that some of the data is either unintentionally or intentionally incorrect.

To provide valuable price information to our visitors, we are using several algorithms to filter out incorrect data and measure the credibility of the user who is submitting the price. The credibility of the user affects the weight of the price used in calculations and the outcome in PriceWiki profile pages.

We are constantly improving our filtering algorithms to provide reliable information about prices.

Data Confidence Score

The Data Confidence Score displayed in percentages shows the credibilitiy of a price. 100% confidence means that the data comes from official sources. Confidence scores below 100% have been calculated based on the user characteristics who submits the price.
