    I'm sure it varies but over a large number of bets, I'm sure the margin from year to year would be similar.

    Anyone got figures for paddy power or some other bookie ?

    What % of what they take in gets paid out ?

    Remember reading somewhere a couple of months ago it was about 8% for paddy p. Check their financial statements.

    Fairly easy to work out. Just add up all the prices of an event, convert to percentages and see what the overround % comes to.

    e.g., football match a bookies might go 6/4 Home, 13/8 Away 11/5 Draw.
    6/4 = 40% (4 div 4+6), 13/8 = 38% (8 div 8+13), 11/5 = 31% (5 div 5+11).

    So total percentage = 109% (40+38+31) which leads to a theoretical margin of 9/109 = 8.25%. Its still only a theoretical margin though, they could win 100% if no-one back the draw and it comes up etc. Over a season it'll be close to correct though.

    Its a good habit to be able to add up a market and see the overround, simpler than it looks as well as there are only about 50 different prices and you soon stop having to do the maths as you know them all off by heart.

    Think he means profit as a percentage of turnover.

    Don't think so.

    From what the OP has says he is looking for Gross Win Margin.

    For instance in 2010 PP online sportsbook has a 8.6% on €1,126m

    You're barking up the wrong tree totally.
