Fee calculator by loweef
How it works
- The widget runs inside a sandboxed iframe from loweef.io. It sets no cookies, has no analytics and makes no requests to other sites.
- Fees and rebate rates come from the same data as the crypto futures fee index and update when they are checked again. You never need to change your code.
- Under the widget there is one visible credit link with the anchor text "loweef". Use data-rel (script) or the rel attribute (iframe) to mark it nofollow, sponsored or ugc. Any choice is fine.
- The one-line script adjusts the height automatically. The plain iframe has a fixed height of 520px.
Prefer the raw data?
The fee figures are open data under CC BY 4.0. Download JSON or CSV from the fee index page. Crypto futures fee index and downloads
