Sports betting odds are basically the laying bricks of the paradigm in **betting terms**. Without odds, everything else is meaningless because you canât make anything out of anything.

## What Are Betting Odds?

For the most part, **odds imply probability**. It refers to the likelihood of an event. It can go both ways as to whether the event is likely to happen or not.

For example, if we say the odds of getting into an accident during rain is high, it means you should drive carefully when itâs raining. How did we know it? From previous statistics by the Ministry of Transport in Ghana, of course.

Similarly, **sportsbooks can analyse previous statistics**, team formation, player form, injury, and lots of other factors. The end result is how likely it is for the team to win the match. The same goes for individual players and the associated markets.

In sports betting, however, odds have another role to play. They can **project how much you will** **win** from a bet. For casino games, you usually donât know how much you can win as the odds vary from round to round. But with sports, you can place informed bets knowing the final outcome.

In different countries, odds have different forms. They might look different but they all refer to the same thingâthe likelihood of the event and your winning potential. Throughout our guide, weâre going to look at the **different types of odds**, **how they are calculated**, and **examples** to understand them better.

## What are Fractional Odds?

This type of odds is very commonly used in the **UK and Ireland**. You can always use them in Ghana if you want because most **modern sportsbooks have the option to change the format**. Fractional odds are simply the ratio of your projected profit and stake.

Itâs called âfractionalâ because itâs denoted as a fraction. Or, ratio, as we already said. The job of fractional betting odds is the same as any other odds format. To tell you the value of your bet as well as how likely the event is.

### How Do You Calculate Fractional Odds?

Calculating fractional betting odds is as simple as looking at it and doing some minor additions. The odds are written in this format â â**Profit/Stake**â.

So, if a football team has **5/2 odds** in Ghana, it means you will **win 5 GHS if you bet 2 GHS**. Now, the ratio is made with integer numbers for better understanding. If you want to think of this as 2.5/1, it means the same thing. But introducing a decimal component only adds to the complexity of the paradigm.

### Fractional Odds Example

Letâs take a look at an example for fractional odds to understand exactly what it means. As our test subject, letâs take **a football match between Ghana and Nigeria** on Ghanaâs home ground.

If you visit an online sportsbook and look at the betting odds, youâll find 2 different projections, 1 for each team. For the sake of simplicity, weâre considering the **match winner** market. But the concept remains the same for all other markets as well.

Letâs assume the odds go like **Ghana 5/2 vs Nigeria 7/2**. Again, this is just an example and you may never find such odds for a real-life match.

You already had the betting odds explained previously. As it seems, you can win 5 GHS if Ghana wins the match and 7 GHS if Nigeria wins the match.

Between the 2, **Ghana is the favourite** and is more likely to win. How do we know it? Because **you can win more for the same wager** if Nigeria wins. The bookmaker has âpeggedâ Ghana as the favourite and most punters think itâs the likely team to win. So, the involved risks are lower for this team. Hence, the projected win is lower.

## What Are Decimal Odds?

Decimal is by far **the most commonly used odds format** all over the world. Most European countries, Canada, Australia, New Zealand, Nigeria, etc. countries use the decimal format for their sports betting needs. Ghanaians, too, are most comfortable with using the decimal odds.

Itâs called the âdecimalâ odds because itâs denoted as a number with **2 decimal positions**. Itâs **also known as European odds** as itâs the most popular in European countries.

In retrospect, understanding the decimal sports betting odds are simpler when compared to fractional odds. Itâs a **direct multiplier for your stake**. So, whatever the projected odds are, you just multiply it with your stake to calculate the final payout.

### How Do You Calculate Decimal Odds?

As we already said, itâs a direct multiplier for your stake. But the important distinction here is that the value you get after multiplying is your total winning and not the profit. To calculate the profit, you must deduct the stake amount from the payout amount.

Just like all the other odds, decimal odds give you the probability of the event. In association with implied probability, **2.00 odds mean thereâs a 50-50 chance the team will win**. Under 2.00 odds mean the team is more likely to win. And the opposite is true when the odds are over 2.00.

### Decimal Odds Example

To keep things streamlined, letâs use the same example as before. The football match between Ghana and Nigeria. Keeping the circumstance the same, Ghana is the favourite and Nigeria is the underdog.

We can say it because we already know it from the previous example. But what if there were no examples? **How would you know who is the favourite and who is the underdog?**

Itâs as simple as looking at the odds.

Letâs say the odds at a reputed Ghanaian bookmaker is **Ghana 1.60 vs Nigeria 2.40**. As the odds for Ghana are shorter than 2.00, it means Ghana has more than 50% probability to win. Hence, itâs the favourite. The opposite is true for Nigeria.

Now, if you decide to wager 100 GHS on Ghana for the match and it wins, youâll take home a decent 160 GHS home. Here, **100 GHS is your wager or investment and the 60 GHS is your profit**.

**For Nigeria**, on the other hand, you can win a massive **240 GHS for the same wager**. Itâs because the odds are longer and youâre going against the probability. Hence, the rewards are larger. In the 240 GHS payout, 100 GHS is your wagering and a whopping 140 GHS is your profit.

However, we donât condone betting on the underdog all the time. It takes a **certain level of experience** in the industry to interpret the betting odds accurately. You also need to analyse a lot of variables before you can actually gather the insights to know that the underdog will win.

## Percentage Odds

Well, the percentage odds are something you wonât find very often in Ghana. In fact, itâs one of the **lesser-known formats** all over the world. As the name suggests, itâs a percentage the online bookmaker gives you. Technically, thatâs simply the implied probability of the event.

So, even though youâre not getting the direct projection of your payout, you can always convert it to any of the known sports betting odds formats.

### How Do You Calculate Percentage Odds?

You donât. You convert it to another format. Percentage odds are basically implied probability and it has an intimate connection with the known odds format. Theyâre all interchangeable. There are plenty of calculators online that you can use to convert the percentage odds to decimal or fractional betting odds explained.

### Percentage Odds Example

If an online bookmaker in Ghana is using this format, itâs basically giving you the probability**. A 50% probability is 2.00 in Decimal and 1/1 in fractional**. Now, you can craft it as you want according to your bet size.

## American Odds

American odds, **also known as Moneyline odds**, are often considered very complex. Thatâs because it is. Itâs not as straightforward as the rest of the betting odds weâve explored so far. It uses a 3-digit number with a **plus (+) and minus (-)** to distinguish between the favourite and the underdog.

The **team with the (+) in the odds is the underdog** and the **team with the (-) in the odds is the favourite**. Interestingly, **when the implied probability is under 50%, itâs (+)** and **when itâs over 50%, itâs (-)**.

### How Do You Calculate American Odds?

The most important thing to keep in mind is that **everything is calculated with the base value of 100** in mind. For Americans, itâs $100. You can think of it as **100 GHS** in a Ghanaian context.

The number with (+) indicates **how much you will win for a 100 GHS bet**. And the number with the (-) indicates **how much you have to wager to win a 100 GHS profit**. If you can wrap your mind around this paragraph, understanding the rest is a walk in the park.

### American Odds Example

Letâs go with the same football match between Ghana and Nigeria. But this time with American odds.

The projected odds, in this case, is **Ghana (-150) vs Nigeria (+250)**.

What it basically means is that if you want to bet in favour of Ghana, you need to wager 150 GHS for a 100 GSH profit. Now, if you want to profit 200 GHS, youâll need to wager 300 GHS.

On the other hand, if you bet on Nigeria, you will win a whopping 250 GHS for a 100 GHS bet. **As itâs the underdog, the payout is considerably larger.**
