Flip the usual question around: if you win this kind of bet 58% of the time, what price do you need? This calculator converts any win rate into its fair (break-even) American odds — the exact line at which the bet neither makes nor loses money.
Read it against the market: if your fair odds are −138 and a book is offering −120, you are getting paid better than your edge requires — value. If the market says −155, the price has eaten your edge. Covrr's Historical Analysis derives this same figure for every model.
