Football, called soccer in the United States, Canada and Australia, is the biggest betting sport in the world. The same match can be bet on in dozens of ways. This guide explains the main markets and how the numbers work, for readers in the UK, USA, Ireland, Canada and Australia.
It is not a guide to picking winners. Nothing here tells you who will win, and no market is free of the bookmaker’s margin.
Unless a market says otherwise, a football bet is settled on 90 minutes plus stoppage time. Extra time and penalty shootouts are not included.
Three formats exist. Fractional odds such as 5/2 are traditional in the UK and Ireland. Decimal odds such as 3.50 are common in Europe, Canada and Australia. American odds such as +250 are used in the United States. They show the same thing, and fractional, decimal and American odds compared explains the conversions.
To find the probability the price implies, divide 1 by the decimal odds. A price of 2.00 implies 50 percent. A price of 4.00 implies 25 percent.
Say, for illustration, a match is priced at home 1.80, draw 3.60 and away 4.75 (invented prices).
If the prices were fair, they would add up to 100 percent. The extra 4.39 points are the bookmaker’s margin. Scaling each back to 100 percent gives about 53.2 percent, 26.6 percent and 20.2 percent. These are what the prices imply, not what will happen. The favourite loses a good share of the time, and draws are common in football, which is why the draw price matters.
The margin has a cost. If the true chances happened to equal those scaled figures, which nobody can know, every pound staked at these prices would lose about 4.2 pence on average, whichever outcome was chosen. Real chances differ from the scaled figures, so the expected result of any single bet can differ, but the margin is still built into the price. How bookmakers and casinos make money explains why.
A price of 1.20 implies about 83 percent. That sounds very safe, but if the price is roughly right, about one in six such bets lose. A series of short-priced bets can be mistaken for safe ones, and a single loss then wipes out several wins. For illustration, suppose 10 pounds is staked each time at 1.20. A win profits 2 pounds. Five wins make 10 pounds, but one loss costs 10 pounds. That is why a price that is “likely” is not the same as a good bet.
Football betting is easy to start and easy to overspend on. Learn the main markets, convert prices into probabilities, and remember that every price contains a margin that favours the bookmaker over time. Set a budget before you start, track what you spend with the spend tracker, and stop if gambling stops being fun. If it feels hard to stop, read about self-exclusion and seek support.
