• 2 To 1 Odds
• 9/2 Mean Odds

Another example of decimal odds in action would be betting on NHL game with odds of 9.0. A $10 stake on odds of 9.0 would earn a total payout of $90 with $80 being won from the sportsbook and your initial $10 stake being returned. You can use the following formula to calculate potential returns with decimal odds: Calculating total payout: Odds. Few bettors use fractional odds for betting sports (other than horse racing), because the conversions to understand return are difficult. To calculate winnings on fractional odds, multiply your bet by the top number (numerator), then divide the result by the bottom (denominator). So a $10 bet at 5/2 odds is (10. 5) / 2, which equals $25. Odds are simply the way prices and payouts are shown at a horse track. The numbers displayed as 4-7 or 2-5 tell you what you pay and how much you get back if the horse you bet on wins. The first number tells you how much you could win, the second number is the amount you bet.

There are two ways odds – or prices – are displayed at racecourses in Britain: the traditional fractional system or the more recently introduced decimal system.

Fractional odds:

These are usually displayed in this format: 4/1.

2 To 1 Odds

In spoken form this is “Four-to-one” and sometimes this can be written as: 4-1.

Odds are just maths. To illustrate some examples, let’s call each number a unit. So:

4/1: For every 1 unit you stake, you will receive 4 units if you win (plus your stake).
7/2: For every 2 units you stake, you will receive 7 units if you win (plus your stake).
9/4: For every 4 units you stake, you will receive 9 units if you win (plus your stake).

If you see fractional odds the other way round – such as 1/4 – this is called odds-on and means the horse in question is a hot favourite to win the race.

In spoken form this is “Four-to-one on”.

9/2 Mean Odds

1/4: For every 4 units you stake, you will receive 1 unit if you win (plus your stake).
1/2: For every 2 units you stake, you will receive 1 unit if you win (plus your stake).

Sometimes you will see Evens or EVS displayed. This is the equivalent of a 1/1 fraction. Again it means the horse in question is expected to win the race.

EVS: For every 1 unit you stake, you will receive 1 unit if you win (plus your stake).

Decimal odds:

These are usually displayed in this format: 5.00.

5.00: Simply multiply this number by your stake to calculate your total potential returns if you are placing a win bet. Unlike fractional odds, your stake is already factored into this price i.e. this is the equivalent of 4/1 plus the 1 unit you stake.

Favourites:

Each race has a favourite. This is the horse most likely to win, which is reflected in having the shortest price displayed with betting operators.

You will see an F alongside the horse’s odds when they are the favourite. If more than one horse has the same odds of winning according to the betting market, this will be displayed as JF, meaning joint-favourite.

What about odds when betting each-way?

Racecourse bookmakers operating at Jockey Club Racecourses must meet (or exceed in the customer’s favour) a standard set of terms if you decide to place an each-way bet.

You will appreciate it is not affordable for bookmakers to pay out on all four places in a four runner race (!) so these agreed terms concerning place part of your each-way bet have to vary dependent on the number of runners and type of race. These are:

• Races with 3 or runners: win bets only, unless the bookmaker chooses to offer 1/5 (one fifth) of the stated odds for finishing 1st or 2nd
• Races with 3 or 4 runners: 1/5 (one fifth) of the stated odds for finishing 1st or 2nd
• Races with 5 to 7 runners (inclusive): 1/4 (one quarter) odds for finishing 1st or 2nd
• Races with 8 or more runners: 1/5 odds for finishing 1st, 2nd or 3rd
• Handicap races with 12 to 15 runners (inclusive): 1/4 odds for finishing 1st, 2nd or 3rd
• Handicap races with 16 to 21 runners (inclusive): 1/5 odds for finishing 1st, 2nd, 3rd or 4th
• Handicap races with 22 or more runners: 1/4 odds for finishing 1st, 2nd, 3rd and 4th
