Types of Odds You May Find: Betting odds explained

There are three primary odds systems that you’ll be able to choose from across most bookies: fractional, decimal, and American odds. Here’s a brief breakdown:

  • Fractional odds: Fractional odds are the most popular odds format on display on British bookmaking sites. The way fractional odds work is that they’ll indicate how much profit you’ll get back from a one-unit stake. How does this work? Let’s say that a unit stake is £10. If you place a wager at 3/1 odds, this simply means that a punter will get paid out 3 times the unit stake. So that would mean that the punter who placed this wager would make £30.
  • Decimal odds: Decimal odds are by far the most popular odds system out there in the online betting world because nearly all of the online bookmakers, regardless of the region, make decimal odds available to you. Decimal odds explicitly tell you how much money you’ll get from a 1-unit stake. Bookmakers will state the bookmaker unit of preference because it could 1 be one, or maybe it’s 10 or 100. If we take decimal odds of 4.00 that will mean your profit will be £40 divided between the £30 profit and the £10 return stake.
  • American odds: The basis of the American odds system is 100, and positive and negative outcomes. If you’re not familiar with the term American odds, you may have seen them before referred to as money lines. What do the positive and negative signs mean? When the bet is negative, it will show how much you need to get to the coveted 100 for a bet, and when it’s positive, it shows you how much profit you’ll be able to make from a typical bet.

Fractional vs. Decimal: Which is better?

While the most user-friendly system is surely the decimal system because it makes the calculations easier. Since it’s the most common system available it will ensure for a safer strategy towards a win. However, it is useful to look at the odds side-by-side for all of the systems. Many websites have conversion charts available and most of our articles will show the odds in both decimal and fractional odds systems.

An easy example is that evens odds are represented as 2.0 in decimal odds and are 1/1 in fractional odds. Many bookmakers also have betting calculators that can help make the job even easier.

A few more key terms for betting odds

There are some terms that you’ll see a lot in the fine print in many of the welcome offers and markets out there. Many of these terms are common in horse racing and football betting markets, so they’ll really help you make more informed decisions. Here’s a quick breakdown of the best of them:

  • Evens: A stake of evens basically means that a punter will be able to win the same amount that he or she staked on a particular bet. In fractional odds, evens are represented by 1/1 and in decimal odds they’re 2.0.
  • Ante-post: As the Latin root implies, ante-post is often used when relating to betting markets for events that are going to happen in the future. They’ll most likely refer to events happening the day after the bet becomes available for wagering.
  • In-play betting: This type of betting refers to the wagers that you’ll place on events from the time they have started until they have finished. Football and horse racing have many opportunities to stake on in-play betting and lots of profit to be found.
  • Starting price: For horse betters, the starting price is a critical term you need to keep in mind; this is the price that you’ll see for a particular race as it’s about to start reflecting the odds for the particular horse and jockey at this point.
  • Total Goals Under/Over: This type of bet will relate to the number of goals scored will be greater or lesser than the number of goals a punter has quoted.
  • Half Time/Full Time: These bets allow you to wager on the scores at the half-time and end-of-match points of football matches. The number of possible combinations you have for this bet is 9.
  • Handicap Betting: This type of betting is common when the match up is seen to be one-sided, or rather, with one side being much more heavily favoured than another. An example of this would be Manchester City and Hull. This would mean that Hull could get ahead by at least one goal.
  • First Goal Scorer: You can also place bets on which player from a certain side will score the first goal in a match. Some bookies will then double and treble these bets if the player scores more goals.
