Know what sells.
Price it right.
The calculator and the public index are free and stay free. Pro is for people who sell every week and want the range, not just the median: where the middle half of the market sits, 90 days of movement, and your numbers saved.

The middle half of the market
Free shows the median. Pro shades where half of all listings sit, on the calculator's price ladder and on every category page, so you know whether your 60% price is in the crowd or above it.
90 days of history, not 7
Every category's download curve back to June, from the archive we imported, plus each new day. Enough to see a season start, not just a week's noise.
Saved calculations and CSV
Name a set of inputs and come back to it from your account. Download the index with the top models per category and up to 90 days of history as CSV.

Questions
- Where does the data come from?
- Once a day: the top 100 models per category on MakerWorld and Printables, a sample of Etsy search results per category, and the catalogues of Shopify stores we track. Nothing is estimated; if a source failed that day, the page says so.
- Can I cancel?
- Any time, from the account page, through Stripe. Access runs to the end of the period you paid for.
- Is the calculator going behind the paywall later?
- No. The calculator is the front door and stays free, multi-plate products included.
