Betting on a team with negative odds is probably a safer bet, but it also costs more and returns a lesser profit. This example is the same for every sport. For the favorite, the calculation for your profit is (100/Odds). Bet Size. So if your team is listed at -150 and you bet $100, your profit would be (100/150). $100 = $66.67. The odds will change heavily if the team makes a late swap. Vegas Odds & Betting Lines. Betting is popular across the US, with many forms taking differing priorities. With Nevada seen as the hub of betting in the country, gamblers flock to Las Vegas to experience the thrills of betting, both on casino games and sporting events.

If you’re new to betting, one of the first things you should do is learn how betting odds work. It’s critically important because it allows you to understand how likely an event is to happen, and what your potential winnings will be. At first, it may appear confusing, however, read our guide and let us explain it to you.

In gambling, odds represent the ratio between the amounts staked by parties to a wager or bet. Thus, odds of 3 to 1 mean the first party (the bookmaker) stakes three times the amount staked by the second party (the bettor).

What is Probability?

The most basic level, betting provides you with the ability to predict the outcome of a certain event, and if your prediction is correct, you will win money. For any given event, there are a certain number of outcomes. Take rolling a dice for instance. If someone rolls a dice, there are six possible outcomes. Therefore, if you bet that the person rolls a ‘one’, there is a 16.67% chance that will happen. What betting odds merely do is present how likely the event is to happen. Bookies most frequently in the UK do this as a fraction, i.e. 4/7, whilst the vast majority also offer the ability to view them as decimals. Again, let us talk you through them. All will become clear.

Using Betting Odds to Calculate Probability

Whenever you see two numbers separated by a trailing slash, i.e. 10/1, this is known as fractional odds. From this, you can calculate how likely a given event is to happen with a calculation. For ease of explanation, let’s replace the numbers with letters i.e. 4/1 becomes A/B. Here is the calculation: Probability (%) = B / (A+B).

• 9/1 can be calculated as 1 / (9 + 1) = 0.10– There is a 10% chance that the event will happen.
• 4/1 can be calculated as 1 / (4 + 1) = 0.20 – There is a 20% chance that the event will happen.
• 1/1 can be calculated as 1 / (1 + 1) = 0.50 – There is a 50% chance that the event will happen.
• 1/4 can be calculated as 4 / (4 + 1) = 0.80 – There is a 80% chance that the event will happen.

Hooray! We’re making progress. Given a fraction, we can now tell how likely (the probability) what we’re going to bet on will happen. Now let’s figure out how much money can be won using betting odds.

Using Betting Odds to Calculate Winnings

Betting odds allow you to calculate how much money you will win if you make a bet. Let’s use the same examples as before, with the same replacement of numbers for letters, i.e. 4/1 becomes A/B. Quite simply, for every value of B that you bet, you will win A, plus the return of your stake.

• 9/1 for every £1 you bet, you will win £9.
• 4/1 for every £1 you bet, you will win £4.
• 1/1 for every £1 you bet, you will win £1.
• 1/4 for every £4 you bet, you will win £1.

What About Decimals?

Decimals are far more common on exchanges, such as Betfair, but all leading betting sites do give you the option to view betting odds in this format. They are an alternative to seeing betting odds in the fraction format, and in our opinion, are easier to work out. Here is the calculation: winnings = (odds * stake) – stake. Let’s illustrate it with some examples

• 9.0 can be calculated as (9.0 * £10 stake) – £10 stake = £80 winnings.
• 4.0 can be calculated as (4.0 * £10 stake) – £10 stake = £30 winnings.
• 2.5 can be calculated as (2.5 * £10 stake) – £10 stake = £15 winnings.
• 1.25 can be calculated as (1.25 * £10 stake) – £10 stake =£2.50 winnings.

Decimal Odds Versus Fractional Odds

In truth, one isn’t better than the other but there is certainly a trend emerging towards decimal odds. Historically fractional odds were used in the UK, especially on racetracks and on the high street. There are two key differences. Generally, decimal odds are easier to understand. Based on this, there has a movement to attract more people to horse racing by making it more accessible to the average punter. Ten years ago, if you were going to Cheltenham, all the odds would be displayed as fractional odds. Now, they’re largely all in decimals.

The second difference between the formats is that fractional odds only represent winnings, and do not include the returned stake compared to decimals which do include the stake. The transition from fractional odds to decimals largely kicked off with the growing popularity of the betting exchanges such Betfair. For odds to change slightly, it’s really difficult to marginally increase or decrease the probability without creating large fractions which are hard to compute for the punter.

The format for betting odds can vary depending on which part of the world you live in. The two most common options used are Decimal and American odds. But what is the difference, how do you calculate returns for each format and convert from one to the other? Read on to find out.

Before we delve into examples on how to calculate bet returns that have been presented in different odds formats, it is important to note that, irrespective of which odds format you use, the potential profit is the same, the presentation just differs.

Odds expression indicating return relative to 100 unit base figure. With money odds, whenever there is a minus (-) you lay that amount to win a hundred dollars, where there is a plus (+) you win that amount for every hundred dollars you bet.

Calculating profits with Decimal odds

Decimal odds are predominantly used in continental Europe, Australia and Canada. The format is a simple numerical representation of the potential return of a bet, which includes the stake amount.

The potential return on a bet quoted in Decimal odds is extremely easy to calculate by simply multiplying the amount you wish to bet by the Decimal odds offered – just remember that the return includes your stake. Here is an example of Decimal odds in a 1X2 soccer market from Pinnacle:

Calculating the potential return for a $100 Bet on Chelsea at 2.270:

Odds x Stake = 2.270 X 100 = 227

As this includes your original $100 stake amount, the potential profit is $127.

Calculating the potential return for a $100 bet on Liverpool at 3.390:

Odds x Stake = 3.390 x 100 = 339

Calculating profits with American odds

American odds are unsurprisingly the default format used in America. They start either with a positive or a negative sign, e.g. -110, or +120. A negative number indicates the amount you must stake to make $100 profit (or the equivalent in your chosen currency) and a positive number indicates how much you might profit if you bet $100 (again, this would be the equivalent in your chosen currency).

Using the example above, if you bet $124 on the Washington Redskins -2.5 handicap with American odds of -124 and they cover the spread, you will make $100 profit (plus your original $124 stake). If you bet $100 on the Dallas Cowboys +2.5 handicap with odds of +112 and they cover the spread, it will return $112 profit (plus the original $100 stake).

As with any odds format, the potential return and profit from a bet is relevant to the stake amount. Using a $100 bet example is the easiest way to calculate profits with American odds, but below is a simple formula to work out potential returns for any stake.

Negative American odds calculation:

(100/Odds) x stake

Positive American odds calculation:

Odds x (stake/100)

If we use the odds from the above example, you could bet $13.75 on the White Sox at -129 and your potential profit is $10.66:

Using the same example for positive odds, you could bet $15 on the Royals at +119 and your potential profit is $17.85:

Odds x (Stake/100) = 119 x (15/100) = 17.85
