How Betting Exchange Commission Works
Commission Basics
- Commission is only charged on winning bets (net profit)
- Losing bets incur no commission charges
- Commission applies to both back and lay bets
- Higher volume traders receive lower commission rates
Example Calculation
Stake: $100 at 3.00 odds (5% commission)
Gross Profit: $100 × (3.00-1) = $200
Commission: $200 × 5% = $10
Net Profit: $200 - $10 = $190
Effective Odds: 1 + ($190/$100) = 2.90
