American to decimal to implied probability
The same price in every form:
| American | Decimal | Implied |
|---|---|---|
| -200 | 1.500 | 66.67% |
| -110 | 1.909 | 52.38% |
| +100 | 2.000 | 50.00% |
| +150 | 2.500 | 40.00% |
| +400 | 5.000 | 20.00% |
The implied column is vig-inclusive: it is what the price asserts, not a fair probability. Calling it one without devigging first is the most common way to invent an edge that is not there.
Where the number comes from
Everything above was computed by the same engine that prices bets, at the moment this page was built — not typed into a template. The build fails if a figure appears here and not in the engine's own output.
