How to use this calculator

This calculator converts each quoted price into an implied probability, then normalizes all outcomes so the no-vig probabilities add to 100%.

Two-way and multi-outcome markets

Keep two rows for a standard yes/no or two-sided market. Add an outcome for three-way soccer markets or other mutually exclusive contracts.

What fair odds mean

The fair price is a proportional normalization of the listed market. It is a baseline, not an independent forecast, and it can still reflect stale prices or incomplete information.
