How to read your result
Implied probability is the win rate needed to break even at the offered price. It describes the price, not a prediction of the outcome.
At −110, you need to win about 52.38% of settled bets to break even. The equivalent decimal odds are 1.909.
Formula and assumptions
For positive American odds A, probability = 100 ÷ (A + 100). For negative odds, probability = |A| ÷ (|A| + 100). Decimal odds D imply probability 1 ÷ D. Pushes return the stake and are excluded from the win/loss calculation.
