Football Qualifying Bet Example
Scenario: Liverpool to win vs Manchester United
Back stake: $50 (required for bonus)
Back odds: 2.4 (bookmaker)
Lay odds: 2.5 (betting exchange)
Exchange commission: 2%
Calculation
Lay Stake = (2.4 ÷ (2.5 - 0.02)) × $50 × 1
Lay Stake = (2.4 ÷ 2.48) × $50
Lay Stake = $48.39
Qualifying loss: ~$1.61 (minimal loss to unlock bonus)
