How do Betting Odds work? By Pablo Luna / Tuesday, 19 Jan 2021 09:18PM If you are not a gambler, catching a glimpse of the latest betting odds in a newspaper or on television can seem bewildering. An Example of How Betting Lines Work. Let's use point spread and say a sportsbook believes that the Cleveland Cavaliers are a 20-point better team than the Washington Wizards. The bookmaker can handicap the Cavaliers by 20 points, which creates our line bet.

Understanding how betting odds work is crucial for success in gambling, whether you want to win at slots or place bets on sporting events. By knowing the odds of potential bets you can calculate your expected winnings and build an entire strategy for a successful session. Let’s see where betting odds come into action and how to read them.

Betting odds on sports events

Knowing what bet to place on any type of sports events all comes down to the odds. These events can come with different odds based on the bookmaker you place a bet at, so you want to find the ones which offer the best odds for your bet.

However, you should make sure you understand the odds properly as different bookmakers use various formats of odds for their events. This is so mainly because of geographical differences. In general, there are 3 types of odds you can come across; Fractional, Decimal and American. Let’s see how each one works and how to easily read them.

1. Fractional Odds

Fractional odds are usually found at British or Irish bookmakers. They are also referred to as traditional odds since they were used early on, originally on horse races. These odds are usually shown with a hyphen or a slash, for example, 5/1 or 5-1. This odd is read as five to one. So what does this mean exactly?

A fraction odd of 5/1 means that you stand to win £5 in profit for every £1 you wager. So the total payout from a £1 wager to a 5/1 odd is £6. The same formula is used for bigger wagers and bigger odds. For example, a wager of £100 on an 8/1 odd comes with a total payout of £900. So that’s 8 times what you bet, so it’s 100 x 8 = £800 which is your profit, plus your initial £100 back, given you the total winnings of £900.

This type of odds is still heavily used today, but as we mentioned earlier it’s mostly focused on the UK.

2. Decimal Odds

Decimal odds are also called European odds and they are mostly used in Europe. They are based on the decimal system and are very easy to understand and to work with. With decimal odds, all you need is a calculator and you can easily calculate your profit. This comes especially in handy if you place a single wager and divide it over several events.

The main reason why decimal odds are easy to calculate is that they give you the total expected return. In fractional odds, you need to calculate the profit first and then add your initial wager. With decimal odds, the entire amount is calculated at one go.

For example, you bet $/£100 on a sports event which has decimal odds of 1.60. In order to calculate how much you can win in total all you need to do is multiply your stake with the decimal odds. In this case, it’s 100 x 1.6 which gives us a total of $/£160. As you can see the profit from betting on an event with this odd is $/£60. Just like in fractional odds the higher the odd, the higher the overall payout will be.

3. American Odds

American odds are used pretty much only in the USA and are also known as Moneyline odds. For a person coming from Europe, they can be very confusing, but in fact, they are very simple to read. They are based on placing a $100 bet, so you can easily calculate the end profit based on that bet. The odds for the favourite on an event come with a minus sign, while the odds for the underdog come with a plus sign.

For example, an event can come with +400 for the underdog and -200 for the favourite. So if you bet $100 on the underdog you would make a profit of $400 plus the initial $100 you stake, giving you a total of $500. On the other hand, for the bet on the favourite, you would need to bet $200 in order to win $100, giving you a total of $300.

As you can see the American odds are actually quite easy to read if you’re betting $100. Problems can arise when you want to bet with smaller or bigger amounts and you will need to do some maths in order to calculate the correct odds.

Betting odds on casino games

When we talk about betting odds the first thing that springs to mind is the odds on sporting events. But betting odds are just as important on casino games, especially on table games like blackjack and roulette. In fact, on these games, the odds and payouts are one of the first things you need to learn.

The simplest odd pairing on roulette, for example, is betting on red or black, odd or even. This bet comes with a payout of 1:1 or simply if you bet $/£10 and win you will win $/£20 in total. However, the odds of this bet differ depending on whether you are playing European or American roulette. The European version has a house edge of 2.7%, while the American version comes with a house edge of 5.26%. This means that the odds are more in your favour on the European version because of the smaller house edge.

Other Betting odds to consider

As you can see odds are pretty easy to read once you know what you’re looking for. It’s imperative to know how to read all types of odds before you embark into the world of betting. You never know which types of odds you can come across at different bookmakers.

Knowing how betting odds work will also come in handy when you want to bet on multiple matches or even on multiple features from a single event. Many bookmakers offer multiple bets on single events so things can start to get a little more complicated when you move away from simply making 1 bet.

Luckily there are ways to reduce the complication because at the end of the day it’s just a calculation. Bookmakers and casinos will often give you a summary of the total you can win, and there are also betting calculators (a good example can be found here https://bookies.com/betting-tools/odds-calculator) which allow you to enter your bets and out comes a total. This is useful as often gamblers will place multiple bets to cover loses, you can’t win them all but you can at least minimise your loss to fight another day.

What Is Line Betting?

Line betting is a form of betting where the market is handicapped to make both betting outcomes equal. The bookmakers achieve this by giving both teams a margin, known as a line. If the bookmakers believe that one side is 12.5 points better than their opposition, you can back them to win by 13 or more points. Alternatively, you can back their opposition to either win the match or lose by less than 13 points. This gives you the chance to back a team at healthy odds, no matter how short or long they are on the Head to Head (H2H) market.

The example below shows the market for a game of AFL between GWS and Port Adelaide. GWS are the heavy favourites on the H2H market, paying $1.30 to win. The bookmakers have declared that in order for the odds to be even, GWS need to start 24.5 points behind their opposition, or Port Adelaide need a head start of 24.5 points.

How Do You Read Betting Lines

How Do I Know If My Line Bet Is a Winner?

Working out the result of a line bet is relatively simple – just add or subtract the line from your team’s score and if their score is higher than their oppositions, it’s a winning bet.

For example, if you backed GWS at the line of -24.5, and GWS ended up winning 102-90, your bet would be unsuccessful because their adjusted total is less than Port Adelaide’s score of 90. Alternatively, if you backed GWS at the line of -24.5 and GWS ended up winning 150-90, your bet would be successful because their adjusted total is greater than Port Adelaide’s score of 90.

What Sports Is Line Betting Available On?

Line betting is available on most sports, including AFL, Basketball, NRL and Tennis.
