Question 1

How does Betfair commission work?

Accepted Answer

Commission is charged on your net winnings when you make a profit on a market. If you bet $100 at 3.00 odds and win, your gross profit is $200. At 5% commission, you pay $10, leaving $190 net profit. If you lose, no commission is charged.

Question 2

How can I reduce my Betfair commission rate?

Accepted Answer

Betfair Points earned through betting activity can unlock lower commission rates. Starting at 5%, active traders can achieve rates as low as 2%. Other exchanges like Smarkets offer flat 2% commission for all users, making them attractive for regular bettors.

Question 3

What are effective odds?

Accepted Answer

Effective odds account for commission on winning bets. At 3.00 odds with 5% commission: Effective Odds = 1 + ((3.00-1) × 0.95) = 2.90. This means a $100 bet returns $290 total ($190 profit), not $300. Always factor commission into your value calculations.

Question 4

Is commission charged on back bets and lay bets?

Accepted Answer

Yes, commission applies to both back and lay bets when they win. For back bets, it's charged on the profit. For lay bets, it's charged on the stake you win from the backer. The calculation is the same - commission rate × net profit.

Question 5

How does commission affect matched betting profits?

Accepted Answer

Commission reduces matched betting returns on the exchange side. With a $50 free bet at 4.00 odds, qualifying losses are higher because commission eats into your lay profits. Factor in commission to accurately calculate guaranteed profit from promotions.

Question 6

What is the commission on Betfair Exchange vs other exchanges?

Accepted Answer

Betfair: 5% base (reducible to 2%). Smarkets: Flat 2%. Betdaq: 2-5%. Matchbook: 1.5-2%. For regular bettors, lower commission exchanges can significantly improve long-term profitability, though liquidity is typically highest on Betfair.
