Impliciete kans = 1 / Decimale odds
Bookmakermarge (Overround) = (1 / Odds₁) + (1 / Odds₂) − 1
Uitbetaling = Inzet × Decimale odds
Marges onder 5% worden als competitief beschouwd; boven 10% zijn typisch voor recreatieve boeken of markten met lage liquiditeit.
Veelgestelde vragen
What is bookmaker margin?
Margin (also called overround or vigorish) is the percentage by which the sum of implied probabilities of all outcomes exceeds 100%. It represents the bookmaker’s expected profit if liability is balanced. A 5% margin means the bookmaker expects to keep $5 of every $100 staked over time.
How does the margin calculator differ from the hold calculator?
Both quantify the same concept. This calculator focuses on the practical impact: enter your stake and see exactly what each outcome pays. The hold calculator is more analytical and emphasises fair (no-vig) odds for comparing bookmakers.
Which bookmakers have the lowest margins?
Sharp Asian books (Pinnacle, Sbobet) historically run 2-3% margins on top markets. European recreational books typically run 5-8%. Promotional or niche markets can exceed 15%.
Why does margin matter for long-term profit?
Margin is the headwind every bet faces. To break even at a 5% margin you need to win above the implied break-even rate. Lower margin books make it mechanically easier to find value bets.
