# AfterFees

> Crypto funding-rate arbitrage ranked by what you keep: net USD after taker fees and order-book slippage at the user's own size (walked through the live order books), plus borrow interest and carry. Read-only: never holds funds, never trades, takes no exchange referral fees.

What sets it apart:
- Net, not gross: every pair is ranked by its net result at a stated size, not by the funding rate.
- Slippage from the live order book at the user's size; max size and breakeven for every pair.
- 50 exchanges and DEXs (20 with the full net calculation), 1186 coins with perps on two or more of them.
- 13 languages (English at /, then /zh, /zh-hant, /ja, /ko, /es, /pt, /ru, /tr, /vi, /id, /fr, /de).
- Default figures: $10,000 per side, held 7 days. The method behind every number is published.
