What do decimal odds mean?
Decimal odds express the total return for a winning selection relative to the stake, subject to the market’s settlement terms. They are a quoted price for a particular outcome, not a guarantee that it will occur.

At decimal odds of 2.50, an illustrative 10-unit stake would return 25 units if the selection wins under the stated terms. That total includes the 10-unit stake, leaving 15 units above it. This is arithmetic using invented teaching numbers, not a current offer.
A void, partial result or other settlement condition may be treated differently. Read the selected market’s rules before applying a simple win calculation.
Convert a price to implied probability
The simple implied probability is 1 ÷ decimal odds. For 2.50, that is 0.40, or 40%. This converts the price into a percentage; it does not prove that the actual event probability is 40%.
Quoted prices across all outcomes can include a margin. For example, two outcomes both priced at 1.90 each imply about 52.63%, totaling about 105.26%. The excess over 100% explains why adding the displayed implied probabilities can be misleading.
Read the outcome and the time period
The same event can offer different markets for the full game, a period, a total or another condition. An odds number without its market and selection label is incomplete information.
Live prices and availability can change as the event develops. A price quoted earlier in a conversation should not be treated as the current selectable price.
