Fractional odds are a traditional way of expressing the potential profit relative to the stake in betting. They are written as a ratio, for example 5/1, which means for every 1 unit staked you could win 5 units of profit.
The calculation is straightforward: profit equals the numerator divided by the denominator, multiplied by the stake. Adding the original stake gives the total return. This format is popular in UK and Irish betting markets and is favoured for its simplicity when comparing multiple selections.
Understanding fractional odds also helps when converting to decimal or implied probability, allowing bettors to assess value across different formats. The formula below summarises the core relationship used by the calculator.
