Bookmaker Percentage Calculator

Bookie In ActionPercentages tell the story of what margin the bookmaker is capable of having when operating a book on any given event. The higher the total percentage of all contestants, the greater the margin in favour of the bookmaker. These are calculated by dividing 100 by the odds plus stake, or the pay out for a one unit bet (say $1). For example, the price of a contestant is 8/10, or 4/5, or  $1.80, or 1.8, or -125, depending on the bookmaker or country where these odds are displayed. 100 is divided by 1.8, giving about 55.6%. If odds are displayed instead of the pay out dividend, the calculation must always include the stake, i.e. 9/2 (45/10 or $5.50 or 5.5 or +450).  converts to 4.5 to 1 and totals 5.5, so divide 100 by 5.5, giving about 18.2%.  This calculation should include EVERY contestant in an event, at least to 50/1 or 100/1, for there can be an extra 40% + in the total for so called long shots over 20/1 in some large fields. The overall percentage is the amount it would cost to back each and any runner to collect a total of 100 units.
 
Unfortunately, some betting organizations seem to work on the basis of  "never give a sucker any break", let alone an even break. It is probably wise to leave these sites that display odds consistently over 130% alone, for nobody can ultimately win with the odds so badly stacked against them. If the odds makers want to survive, then they must start giving out odds that encourage money into the bag first, then worry about where it is going to be paid out. The main reason bookmakers in Australia are disappearing so rapidly from racetracks is that many are more concerned with getting higher margins, and laying runners at the shortest possible odds, rather than trying to  increase their  holdings. Punters have become fed up and no longer have any incentive to go to the track.  It is unlikely that one in five racing starting price these days is above what the tote dividend pays, especially at the weekday meetings.  It was once closer to 50/50.
 
As a guide to your betting on futures events in general, under 108%, excellent, but unlikely; 108%- 116%, very good; 116%-122%, good; 122%-128%, fair; 128%-140%, poor; more than 140%, bad - leave it alone. Allow a little more percentage for very large fields, such as golf events.  In a "two horse race", such as an Aussie Rules football match, percentages should never exceed 110%, with about 105%-108% being the norm, and there is no reason (bar turnover tax), that  it should not be nearer the standard casino odds for US football  of 10/11 (104.8%). Even getting a 1% advantage from one bookmaker over another will make a large difference to your balance in the long run, so shop around.
