Decimal odds are commonly found on betting exchanges such as Betfair and they provide a simple way for bettors to calculate their betting returns. Although the majority of bookmakers & betting websites will offer their users the opportunity to use decimal odds as their default option, the majority of online UK betting sites will automatically use fractional odds on the majority of their sports betting markets.
They offer a far simpler way of calculating your returns and your stake will always be included in your returns.
Examples of Decimal Odds – 1.63, 2.02, 2.50, 3.10
In decimal odds – 2.00 represents even money and anything priced at 1.99 or lower represents an odds-on bet.
