The fraction is derived by rounding profit per unit to four decimal places. This is not an estimate of actual chances.

How to read the result

Decimal odds of 2.50 equal fractional odds of 3/2 and American odds of +150. In all three cases, a stake of 10 units produces 15 units of theoretical profit for a winning outcome, before costs.

Negative American odds describe how many units must be staked for 100 units of profit: −200 equals decimal odds of 1.50. Implied probability is 100 divided by decimal odds, expressed as a percentage.
