What the price difference actually costs
Betfair Exchange builds about 3.5% into its prices; William Hill about 5.0%. That gap of 1.5 percentage points is not an abstraction — it is money that leaves your account on every settled bet, win or lose.
Indicative cost of the gap
Stake £5,000 across a season and the difference between them is roughly £75 — in Betfair Exchange's favour.
A simplified illustration on total turnover, not a prediction. It ignores which bets you win, because the margin is charged either way — that is precisely the point.
A welcome offer is paid once. This gap is paid every time you bet, which is why we weight price at 30% of the score and most comparison sites do not weight it at all.
