Calculating Payouts From Fractional Odds

Fractional odds have been used in bookmaking primarily in the
United Kingdom. They have been more or less replaced by decimal
odds in recent years, but a lot of bookmakers and bettors still
prefer this format. Although this odds format is often
considered more complicated than the decimal or moneyline
format, the calculations required for working out potential
profits and payouts is actually reasonably straightforward.

We provide the necessary calculations on this page, along
with some examples to highlight how it works in practice. We
also include a chart listing some of the more commonly-used
fractional odds, with the associated profits and payouts.
