Decimal vs Fractional Odds: Football Betting Made Simple

Football betting odds tell you two things: how likely something is to happen and how much money you will win if it does. Most people don’t realize that the way odds are written can change depending on where you live or what website you use.

Two of the most common formats are decimal odds and fractional odds. If you want to bet smart and win more often, you need to understand both. In this article, we will explain what these odds mean, how to read them, how to convert one to the other, and how they affect your decision when placing bets.

What are decimal odds in football betting?

Decimal odds are used in most countries, especially across Europe, Asia, Australia, and Canada. They are the easiest to understand. Decimal odds show the total return you will get for every unit you bet, including your original stake. So if the odds are 2.00, and you bet 10 dollars, your return will be 20 dollars. That means 10 dollars profit and your 10 dollars stake back.

Here’s a simple way to calculate it:
Decimal Odds × Stake = Total Return

For example, if Manchester United has odds of 1.80 to win against Aston Villa, and you bet 50 dollars, your return would be:
1.80 × 50 = 90 dollars

You make 40 dollars profit and get your 50 dollars back. Decimal odds are straight and do not require extra calculation.

What are fractional odds in football betting?

Fractional odds are mostly used in the United Kingdom and Ireland. They look like this: 5/1 or 7/4. These odds show you how much profit you’ll make compared to your stake. So 5/1 means you’ll win 5 dollars for every 1 dollar you bet. If you bet 10 dollars, you get 50 dollars profit plus your 10 dollars stake.

Here’s the formula:
(Fraction Numerator ÷ Denominator) × Stake = Profit

Using a real example, let’s say Chelsea has odds of 7/4 to beat Tottenham. If you bet 20 dollars:
(7 ÷ 4) × 20 = 35 dollars profit, plus your 20 dollars stake

Total return: 55 dollars

Fractional odds can look confusing at first, but they follow a pattern. A high number on the left (numerator) means a high return. If the numerator is smaller than the denominator, the team is more likely to win but gives less profit.

What’s the difference between decimal and fractional odds?

The biggest difference is how the numbers are shown and what they represent. Decimal odds show the total payout. Fractional odds show only the profit. This changes how you read them. A decimal odd of 3.00 is the same as a fractional odd of 2/1. Both mean you get double your money in profit.

Let’s look at this in a table for better clarity:

As the odds get bigger, the possible return increases, but the risk also goes up. Favorites usually have low odds. Underdogs have high odds.

How do decimal and fractional odds affect football betting strategy?

Understanding odds helps you calculate the real chance of something happening. Bookmakers set odds based on what they think will happen, and they add a small margin for profit. But sometimes they get it wrong, or public betting influences the odds. That’s where smart bettors find value.

To find value, you must estimate the chance of a team winning and compare it with the odds.

Here’s a simple example:

Let’s say Arsenal plays at home, and you believe they have a 60 percent chance of winning. The decimal odds given are 2.20.

To find the fair odds, use this:
Fair Odds = 1 ÷ Probability

Fair odds = 1 ÷ 0.60 = 1.67

But the bookmaker gives 2.20. That’s higher than 1.67, so it could be a value bet.

Fractional odds 6/4 mean the same as 2.50 decimal. You can also reverse the calculation:
Fraction = Decimal – 1

This gives you a way to convert and spot better value. Websites like Betfair or Pinnacle use decimal odds, while traditional bookmakers like William Hill still show fractional odds.

Which odds format is better for beginners?

Decimal odds are better for beginners because they are faster to calculate and easier to compare. With one quick glance, you know what your total return will be. Fractional odds take more time to get used to, but some experienced bettors prefer them, especially when looking for traditional bookmakers or historical betting forms in newspapers.

Imagine two friends are placing bets:

James uses decimal odds. He sees that Bayern Munich has odds of 1.65. He places 100 dollars and knows right away he will get back 165 dollars.

Moses uses fractional odds. He sees 13/8 on the same team and takes longer to figure out the return. He must divide 13 by 8 and multiply by his stake. For most people, the decimal system just saves time.

Can I switch between the two?

Yes, most betting platforms today let you choose your preferred odds format. There is usually a button or dropdown that lets you switch. Some advanced punters even use both formats to double-check value. For instance, if they notice that a certain bookmaker offers 9/4 while another gives 3.25, they calculate the better return and act quickly.

FAQ on Football Betting Odds: Decimal vs Fractional

What do odds like 1.90 mean in football betting?

It means if you bet 1 unit, you get 1.90 units back. That includes your stake. So your profit is 0.90 units.

How do I convert fractional odds to decimal odds?

Use this formula: Decimal = (Numerator ÷ Denominator) + 1

For 5/2, Decimal = (5 ÷ 2) + 1 = 3.50

How do I convert decimal odds to fractional odds?

Subtract 1 from the decimal and simplify the result. For example, 4.00 – 1 = 3.00. That becomes 3/1.

Why are some odds listed as evens?

“Evens” or “Even money” means the odds are 1/1. You double your stake if you win. In decimal format, it’s 2.00.

Do odds always show the real probability?

No. Bookmakers build in a profit margin. Odds reflect estimated probability plus a cushion for the bookmaker. A fair game would total 100% probability, but bookmakers usually add up to 110% or more.

Are odds the same across all websites?

Not always. Odds can differ based on betting volume, team news, or local markets. Comparing odds across sites is one way to find better value.

Can odds move after I place a bet?

Yes. Odds can change based on new information like injuries, lineup changes, or sudden betting spikes. But once you place your bet, the odds are locked for that wager.

Conclusion

If you want to predict football results better and make smarter bets, understanding the difference between decimal and fractional odds is one of the first steps. Decimal odds are easier and more common in modern betting, while fractional odds are still used in traditional settings.

Knowing how to read, convert, and compare them gives you an advantage. Always check for value, stay within your bankroll, and learn to think in terms of probability, not luck. This approach sets you apart from casual punters and helps you build long-term success.
