Accumulator bet ticket calculator and odds converter between decimal, fractional and American formats.
Two calculators for making sense of betting odds. Neither recommends nor predicts anything â both simply work out the numbers you give them.
The accumulator calculator multiplies the odds of each selection and shows the combined odds and the possible return on your stake. It is useful when you want to see how quickly adding a fourth or fifth selection changes the potential return, and with it the chance of the whole bet landing.
The odds converter translates between three ways of writing the same number: decimal (2.50), used across Europe, fractional (3/2), used in Britain, and American (+150). Alongside that it shows the implied probability, meaning the chance of winning the odds represent â bookmaker's margin included.
