Break-Even Percentage
The win rate you need to profit at given odds. At -110, you must win 52.4% of the time to break even. Calculated as risk / (risk + potential win).
Like a toll road: you need to earn enough on the trip to cover the toll, not just break even on gas.
Why it matters
Every bet has a built-in hurdle rate — if you can't clear the break-even percentage over time, you're losing money no matter how good your picks feel.
How DMP uses this
DMP displays break-even percentage alongside implied probability so users can see exactly what win rate they need to justify a bet at the given odds.
Common mistake
Thinking you only need to win 50% of bets at -110 odds — the vig means you actually need 52.4%, and that 2.4% gap is the book's profit.
