Betfair — real bookmaker margin
We measure the margin Betfair actually builds into its 1X2 football prices — not the one it advertises. 1,605 matches in the last 30 days, every price taken from our own odds snapshots. We have no commercial relationship with Betfair or any other bookmaker.
Last computed:
Betfair has fewer than 50 matches with complete 1X2 prices in the last 30 days, so it is not ranked yet. The figures below are shown for transparency and should be read as provisional.

What that margin costs you
At a 1.44% margin, every 100 units you stake with Betfair carry an expected cost of 1.42 units before any skill is involved. Someone staking 100 units a month pays roughly 17 units a year in margin alone — 0 units more per year than at the cheapest bookmaker we track (BetAnything, 4.95%).
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 Betfair compares to its peers, not just to itself.

Frequently asked
What is Betfair's real margin on 1X2 football odds?
Measured from 1,605 matches in the last 30 days, Betfair's average 1X2 margin is 1.44%. That means the implied probabilities of its home/draw/away prices add up to about 101.4% instead of 100%; the excess is the bookmaker's built-in fee.
Which leagues is Betfair most expensive on?
On the matches we priced in the last 30 days, Betfair's highest margins were on Greek Super League (2.44%) and its lowest on La Liga (0.71%). Smaller competitions almost always carry a higher margin at every bookmaker.
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.
