Understanding Break-Even Percentage
The break-even percentage tells you how often you need to win to profit at given odds. At standard -110 juice, you need to win 52.38% of your bets just to break even. This is why the vig matters — it's the tax on every bet.
Break-Even Formula
For negative odds: Break-Even % = |Odds| / (|Odds| + 100)
For positive odds: Break-Even % = 100 / (Odds + 100)
For positive odds: Break-Even % = 100 / (Odds + 100)

- Evaluate the true cost of juice at different sportsbooks
- Compare value between different odds on the same bet
- Set realistic expectations for your betting performance
