Try it on your own price
Type the two sides of any market. You get the consensus fair probability and how far the four methods disagree about it — the number a one-figure no-vig calculator leaves out.
Loading the engine’s answers…
Every answer here was computed by the same engine that built this page, for all 6,737 two-way markets between −600 and +600. Nothing is calculated in your browser: a second implementation drifts from the first, and the drift is invisible until someone bets on it. Prices that do not form a real two-way market are refused rather than rounded into one.
A book offering -145 / +125 is asserting probabilities that sum to more than one. Removing that margin gives the favourite:
| additive | 57.37% |
| multiplicative | 57.11% |
| power | 57.50% |
| shin | 57.37% |
Consensus 57.34%, and the four methods disagree by 0.39 points. Every other no-vig calculator returns one number.
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.
