How do William Hill odds work?
The odds at William Hill work just like those at most other sportsbooks, they reflect the probability of an event happening, as determined by William Hill’s oddsmakers.
For example, if Fulham are listed at 9/2 to beat Chelsea in a Premier League match, that means a £2 (or currency equivalent) bet on Fulham would return £11 if they win, a £9 profit, plus your £2 stake. These odds also indicate the implied probability of the outcome. In this example, 9/2 converts to an 18% chance of Fulham winning the match.
To make this easier to understand, William Hill provides a free bet calculator. You enter the odds and your bet amount to instantly see your potential return, and the implied probability of the event happening. This can help you get comfortable with how William Hill odds work before placing any bets.
How to read William Hill odds
The way you read William Hill’s betting odds depends on the odds format you choose. The brand supports three main formats: fractional, decimal, and American. Here’s how to read each one, with some examples:
| Format Example | Example | Stak | Return | Profit |
| Fractional | 5/1 | £10 | £60 | £50 |
| Decimal | 6.00 | £10 | £60 | £50 |
| American | +500 | £10 | £60 | £50 |
Fractional
Just as we found during our Betfred review, William Hill displays odds in a fractional format by default. That makes sense, as this format is easy to understand and is preferred by most bettors. Reading fractional odds is straightforward: the first number (the numerator) shows how much you can potentially win, while the second number (the denominator) shows how much you need to bet to win that amount. For example, if you see odds of 5/1, it means that for every £1 you stake, you’d make £5 of profit, plus your original £1 stake back, for a total return of £6. If the odds are 1/2, the idea is the same but reversed: for every £2 you stake, you’ll make £1 of profit, giving you a total return of £3.
Decimal
The decimal format is another William Hill odds format that’s simple to understand. It shows your total return per unit staked. Unlike fractional odds, it already includes your bet amount in the number displayed. To read decimal odds, you just multiply your bet amount by the decimal figure. For example, if the odds are 6.00, a £10 stake would return £60 in total. This is made up of £50 profit, plus your £10 stake. This format makes it simple to compare William Hill odds with other sportsbooks.
American
American odds, also called moneyline or US odds, can seem a bit tricky at first compared to fractional or decimal formats, but once you get used to them, they’re also very straightforward. When you select the American odds format at William Hill, the odds will appear as either a positive or a negative number. A positive number shows how much profit you’d make from a £100 bet, while a negative number shows how much you’d need to bet to make a £100 profit. For example, if the odds are +200, you’d make £200 profit based on a £100 stake. This format also makes it easy to see which side is the favorite and which is the underdog: a plus sign represents the underdog, while a minus sign represents the favorite.

Odds quality
After carrying out an in-depth William Hill review, we found that this online sportsbook consistently offers competitive odds across the board. In the UK for example, their horse racing odds rank among the best in the industry, thanks in part to the brand’s ongoing ‘Best Odds Guaranteed’ (BOG) promotion. Odds for player props are also notably strong, often outperforming other major sportsbooks. Combine that with daily odds boosts on select markets, and it’s clear that William Hill is an excellent choice in terms of finding value odds.
Odds margins
The odds margin, also known as the bookmaker’s “overround” or “vig” represents the built-in profit a sportsbook takes from each bet. During our tests, William Hill consistently showed margins at the lower end of industry standards. For most markets, the brand’s margins are below 10%, and for some Premier League football and major tennis tournaments, they can drop below 5%. For comparison, some competitors take margins in the 12-15% range, giving William Hill a clear advantage.
