Betfair Commissions & Charges

Betfair Commission is the only charge that the majority of customers on Betfair will ever have to pay.

Each market that you bet on has a Market Base Rate (MBR). This Rate is the maximum percentage of your winnings that you will pay in commission. To find out what the Market Base Rate is for a market, simply click on the “Rules” section of the Market you wish to place a bet on to find it.

Betfair Commission is automatically removed from your winnings when the market is settled.


For example, Victorian thoroughbred racing (i.e. the Melbourne Cup market) has a 6% Market Base Rate.

You place a $50 BACK bet on Prince Of Arran in the Melbourne Cup at odds of $3.00. Prince Of Arran wins. This means that your winnings is $100 ($150 return – $50 stake).

With the Market Base Rate at 6%, the commission you will pay is $100 x 6% = $6.00.

What are the different Market Base Rates?

Market Base Rates for Sport and International Racing Markets is currently 5%.

On Australian thoroughbred, harness and greyhound racing, the Market Base Rate ranges from 6% – 10% depending on the state and racing code. Betfair is charged different fees to provide the betting exchange from state to state. These variable Market Base Rates are reflective of the fees each racing body charges Betfair.
