Example Calculation

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)

Understanding Matched Betting

What is Matched Betting?

Matched betting is a risk-free betting technique that exploits free bets and bonuses offered by bookmakers. By placing opposite bets (back and lay), you guarantee a profit regardless of the outcome.

How Does It Work?

  • Place a back bet on an outcome (e.g., Team A to win)
  • Place a lay bet against the same outcome (Team A not to win)
  • Use calculated stakes to guarantee profit or minimize loss
  • Profit from free bets and bonuses offered by bookmakers

Key Benefits

Mathematical certainty, not gambling

Guaranteed Profit

Extract value from free bets and bonuses

Legal & Tax-Free

Completely legal in most jurisdictions

Important: Success requires discipline, accurate calculations, and proper bankroll management.
