How do football odds work? A plain answer, using Sunday's game at Anfield
For anyone who has looked at a match price and not known what the numbers mean. What a price is, how to turn it into a chance, why the three add up to more than one, and why it changes.
Football odds are a chance written as a number. A price tells you two things at once: how much you would get back if you backed that outcome and it happened, and, turned around, how likely the market thinks that outcome is. On this site, and across most of the world, prices are written as decimals. A price of 2.00 means you get back twice what you staked, and that the market gives the outcome roughly an even chance. A price of 4.00 means four times your stake back, and roughly a one-in-four chance. Lower numbers mean more likely; higher numbers mean less likely.
That is the whole idea. Everything else on this page is detail.
What does a decimal price actually pay?
A decimal price is the total you get back for each unit staked, including the unit itself. Stake 10 at 2.55 and you get 25.50 back if you win: your 10 returned, plus 15.50 profit. Stake 10 at 1.50 and you get 15 back: your 10, plus 5 profit. Stake 10 at 3.49 and you get 34.90 back. If you lose, you get nothing back, whatever the price was.
The profit part is always the price minus one, multiplied by the stake. That is why a price of 1.00 cannot exist: it would return only your stake, with no profit, for taking a risk. Prices on real matches start a little above 1.00 for the heaviest favourites and run into the tens for the longest shots.
How do I turn a price into a chance?
Divide 1 by the price. That gives you the implied probability, which is the chance the price implies.
Take Sunday’s Premier League match between Liverpool and Arsenal at Anfield, which kicks off at 17:30 CET on 1 November. At 06:51 CET on Sunday, BettingBeast’s feed had Liverpool at 2.97 to win, the draw at 3.49 and Arsenal at 2.55.
Liverpool: 1 divided by 2.97 is 0.337, so about 34%.
The draw: 1 divided by 3.49 is 0.287, so about 29%.
Arsenal: 1 divided by 2.55 is 0.392, so about 39%.
Read like that, the market makes Arsenal, the away side, slightly the more likely winner, puts Liverpool a little behind, and gives the draw a bit under three chances in ten. None of those numbers is a forecast. They are a snapshot of what people were willing to pay for each outcome at 06:51 CET on Sunday, and they had moved a little since Friday, when the feed first captured this game at 13:54 CET with Liverpool at 3.06 and Arsenal at 2.50.
Why do the three chances add up to more than 100 per cent?
Add the three chances above together: 34 plus 29 plus 39 is 102. One of the three outcomes must happen, so in a perfect world the chances would add up to exactly 100. The extra is the margin, sometimes called the overround: the fee the bookmaker builds into its prices so that, whatever the result, it expects to keep a small share of everything staked. A margin of 2% is small. Some markets carry 5% or more, and the higher the margin, the worse the prices are for everyone backing them.
This is also why the chances you work out from prices are called implied, not true. They tell you what the market is charging, which is a mix of how likely each outcome is and how much the bookmaker is taking. To get closer to the market’s actual view, you can scale the three down so they add to 100: Liverpool about 33%, the draw about 28%, Arsenal about 39%. The order does not change; the numbers just shrink a little.
Now and then a snapshot shows three prices that add up to slightly less than a whole. Treat that snapshot with care, and trust the live page over it.
What is a favourite, and what is an underdog?
The favourite is the outcome with the shortest price, which means the lowest number and the highest implied chance. The underdog is the outcome with the longest price. At Anfield on Sunday, Arsenal at 2.55 are the favourite and Liverpool at 2.97 the underdog, though the gap is small. When one team is priced at 1.30 and the other at 10.00, the gap is large and the match is seen as one-sided.
A short price is not a promise. A team at 1.50 has an implied chance of about 67%, two in three. The same number says the market expects that team to fail about one time in three. Favourites lose every weekend, and the price already allows for it.
Why is the draw usually above 3.00?
In most football matches each of the three outcomes is less likely than a coin flip, because there are three of them, not two. A draw that happens about one time in four would be priced at around 4.00 before the margin; one that happens three times in ten, around 3.30. Draws are priced below 3.00 only when two very even and very cautious teams meet, which is rare. Sunday’s 3.49 is a fairly typical draw price for a close game.
Why do odds change before a match?
A price is set by people and moved by people. Three things move it most often.
Team news is the biggest. If a club confirms on Friday that its best striker is out, the chance of that club winning falls in the market’s eyes, so its price lengthens, and the opponent’s price shortens. Bayern Munich’s price to win at Atlético Madrid on Tuesday went from 2.04 at 18:20 CET on Saturday to 2.35 at 21:38 CET the same evening, after three Bayern players went off injured against Dortmund. The Markets desk covered that move on Sunday.
Money is the second. If far more is staked on one outcome than the bookmaker expected, it shortens that price and lengthens the others, to balance what it stands to pay out.
Other results are the third. A match can mean more or less depending on what happened elsewhere. On Saturday Manchester City lost to Brighton, so Arsenal now go top of the table if they win at Anfield; that changes the mood around the game, and sometimes the price.
Because prices move, a price without a time next to it is not much use. Every price on this site carries the time it was read, in CET, and links to the live page, where the number may already be different.
What other prices will I see on a match page?
Beyond the three match prices there are usually two more lines. The goals line splits the match at a number of goals, most often 2.5: “over 2.5” means three goals or more, “under 2.5” means two or fewer. For Liverpool v Arsenal at 06:51 CET on Sunday the line was 2.5, with over at 1.93 and under at 2.02, which is close to even either way. The handicap line gives one team a head start in goals so that the two sides are closer to even; a line of level, as at Anfield on Sunday morning, means the market gives neither side a start. A separate explainer on this site walks through both in more depth.
In plain words
A football price is a chance written as a number. Divide 1 by the price to see the chance the market gives an outcome. Lower prices mean more likely, higher prices mean less likely, and the three chances in a match add up to a little more than 100 per cent because the bookmaker’s fee is built in. Prices move with team news, money and other results, so a price is only meaningful with the time it was read. None of it tells you what will happen. It tells you what the market thought, at that moment, and that is all it has ever claimed to do.
Questions readers ask
How do football odds work?
A price shows how much you get back for each unit staked if the outcome happens, and 1 divided by the price is roughly the chance the market gives that outcome.
What does a price of 2.55 mean?
For each 1 staked you get 2.55 back if you win, so 1.55 profit plus your stake, and the market puts the chance at about 39%.
Why do the three chances in a match add up to more than 100 per cent?
The extra is the margin, the fee the bookmaker builds into the prices so that it keeps a share whatever happens.
Why do odds change before a match?
Prices move when team news arrives, when a lot of money goes on one side, and when results elsewhere change what the match means.
Does a short price mean a team will win?
No. A price of 1.50 means the market thinks the outcome is likely, about two times in three, which also means it expects to be wrong about once in three.
