The 'Market Base Rate' (MBR) is the maximum commission rate you pay on some markets and is determined by your country of residence. If you are opted into “My Betfair Rewards” then Market Base Rate only applies in Australasian markets.

Examples of how it can affect your bet: 

• If the 'Market Base Rate' is 5% and your bet stands to make £100 profit, you will have £95 plus your stake returned. Having a Discount Rate of 10% would mean that you receive £95.50 plus your stake.
• If the Market Base Rate is 6.5% and your bet stands to make £100 profit, you will have £93.50 plus your stake returned. Having a Discount Rate of 10% would mean that you receive £94.15 plus your stake.
  

The default Market Base Rate varies depending on where you live. See below for details:
