What that margin costs you
At a 10.10% margin, every 100 units you stake with William Hill carry an expected cost of 9.17 units before any skill is involved. Someone staking 100 units a month pays roughly 110 units a year in margin alone — 53 units more per year than at the cheapest bookmaker we track (BetAnything, 4.97%).
Margin over the last 90 days
Each point is the average margin of the matches whose last pre-match price we captured that week (weeks with fewer than 10 matches are hidden). The most recent point can still move slightly as late prices arrive.
Margin by competition, last 30 days, leagues with at least 20 priced matches. 'Market avg' is the average margin of all bookmakers we track on that league — how William Hill compares to its peers, not just to itself.

Frequently asked
What is William Hill's real margin on 1X2 football odds?
Measured from 2,655 matches in the last 30 days, William Hill's average 1X2 margin is 10.10%. That means the implied probabilities of its home/draw/away prices add up to about 110.1% instead of 100%; the excess is the bookmaker's built-in fee.

How we measure this
For every match, we take each bookmaker's most recent pre-kick-off 1X2 prices from our own odds snapshots (in-play prices are excluded), convert them to implied probabilities (1 divided by the odds) and sum them. A fair market sums to exactly 100%; anything above that is the bookmaker's margin — the built-in fee you pay on every bet. We average that margin across all matches the bookmaker priced in the last 30 days. Nobody pays us for placement and no affiliate deal reorders this table: it is arithmetic on captured prices, recomputed every hour.
