Hi Cobra_Kai,
Your
rakeback can be negative because of the deductions made by Full Tilt, mainly deposit fees that they carry over to you. Below you may find the full formula used, you can also view a description and breakdown of all Full Tilt deductions from
Full Tilt Rake Tracking page.
Your 27%
Full Tilt rakeback is based on Full Tilt Net Rake. Below is the actual formula used by Full Tilt to calculate your net revenue:
Rake + Tournament Fees – Bonus – Player Added – Used Points – Player Fees - Fraud = Net Rake
Your rakeback is 27% of Net Rake
Legend:
Rake - Money earned while playing in ring games
Tournament Fees - Fees a player pays when joining a tournament
Bonus – Bonuses a player earns
Player Added – Money Full Tilt has to add to tournaments. For example, if there is a $10,000 guaranteed tournament and Full Tilt only gets enough buy ins for $9,000, they split the remaining $1,000 by the players in the tournament.
Used Points – Full Tilt Points used on the site or in the store are deducted at a rate of $0.005 per point.
Player Fees – Transaction fees when players deposit money onto the site
Fraud - Bad credit etc.
