How to Read Betting Odds: A Complete Beginner's Cheat Sheet
If you're new to betting, the numbers next to each team can look like a foreign language. But they are simply a code. Once you crack it, you'll see that odds tell you two crucial things: how much money you stand to win, and what chance the bookmaker is giving that outcome. This cheat sheet will help you read them in seconds.
Decimal Odds: The Total Return
Decimal odds are the standard in Europe and the easiest format to understand. They show you the TOTAL amount you will get back for every £1 you bet, including your original stake.
How to Read: The bigger the number, the bigger the potential payout (and the less likely the outcome, according to the bookmaker).
- Cheat Sheet:
1.50: Heavy favorite. A £10 bet returns £15 (£5 profit).
2.00: Even money. A £10 bet returns £20 (£10 profit).
3.00: Underdog. A £10 bet returns £30 (£20 profit).
5.00: Long shot. A £10 bet returns £50 (£40 profit).
Calculation: Stake x Decimal Odds = Total Return.
Fractional Odds: The Profit
Fractional odds are the traditional format in the UK, especially for horse racing. They show you your PROFIT relative to your stake.
How to Read: The number on the left is your potential profit, the number on the right is your stake.
- Cheat Sheet:
1/5 (one-to-five): Heavy favorite. For every £5 you bet, you win £1 profit. A £10 bet wins £2 profit (total return £12).
1/1 (evens): For every £1 you bet, you win £1 profit. A £10 bet wins £10 profit (total return £20).
5/1 (five-to-one): For every £1 you bet, you win £5 profit. A £10 bet wins £50 profit (total return £60).
10/1 (ten-to-one): For every £1 you bet, you win £10 profit. A £10 bet wins £100 profit (total return £110).
Calculation: (Stake x Fraction) + Stake = Total Return.
Quick Conversion Tips
Fractional to Decimal: Divide the fraction and add 1.
5/1 = (5/1=5) + 1 = 6.00
1/2 = (1/2=0.5) + 1 = 1.50
Decimal to Fractional: Subtract 1 and convert the decimal to a fraction.
4.00 - 1 = 3.00 = 3/1
1.80 - 1 = 0.80 = 4/5
What the Odds Tell You (Implied Probability)
Odds also represent a percentage chance. The formula for decimal odds is: (1 / Decimal Odds) x 100.
1.50 odds imply a (1/1.50) * 100 = 66.7% chance.
2.00 odds imply a 50% chance.
4.00 odds imply a 25% chance.
If you think a team's chance is higher than the implied probability, you've found a potential value bet.
