Betfair Commission explained. Betfair charges a Commission on your net winnings on a market. If you have a net loss on a market you do not pay commission and if you have a net win on your market you pay commission.
Commission is calculated by multiplying your net winnings by the Market Base Rate and it is shown on the Rules tab. From this betfair will apply a discount. The more you bet with betfair.com the greater the discount you will receive
