Understand the numbers

What do your odds mean?

See the implied probability & possible return behind decimal odds. An explanation, never a prediction.

Implied probability50.0%

Total return if successful20.00

Profit if successful10.00

Amounts use the same currency as your stake. Return includes the stake. A losing bet loses the stake. Implied probability includes the price's margin; it is not the true chance of winning.

Three useful habits.

Practical betting information

Read the market, understand the return & check what the price includes.

Check the market Separate stake, return & profit Understand the margin
