How our data works
Two kinds of prices
User submissions are prices shared anonymously by people through our 30-second form. We never ask who you are. No account, no email, no name.
Prices from public posts are prices people shared publicly on forums and social media (for example, asking “is this quote reasonable?” on Reddit). We note just the price, the service, and a rough location, nothing else, and we always label these so you can tell them apart from direct submissions. They exist so a page is useful before your neighbors have contributed; as real submissions arrive, older ones age out of the statistics.
How bad data gets removed
- Outlier rejection: prices more than three standard deviations from the recent average for that service are automatically excluded from every chart and statistic.
- Community votes: every report has “does this look right?” buttons. Reports that the community consistently flags are removed from the site automatically.
- Rate limits: anonymous submitters are limited in how many prices they can add, so no one person can move a median.
What the numbers mean
The median is the middle price: half of the reports were below it and half were above. The typical range covers the middle 50% of reports. We show medians rather than averages because one extreme price can’t distort them.
Prices are what individual people reported paying, in the currency they paid. They are not quotes, offers, or guarantees, and any specific provider’s current pricing may differ.
Sources and takedowns
Prices taken from public posts keep a link to their source. We keep no usernames or author identities, and we regularly re-check sources: anything deleted at the source gets removed here too. To report a problem with any price, use the vote buttons or the source link on the report.
