If you’re new to sports betting, understanding odds is one of the first things you need to learn. They determine how much you can win and reflect the likelihood of different outcomes. To place informed bets, it’s important to understand how to read odds − whether you’re backing a favorite, taking a risk on an underdog, or calculating potential profits
This guide will walk you through the different types of odds, how they’re calculated, and how to use them effectively. You’ll also discover common mistakes bettors make − and how to avoid them.
What are odds in sports betting?
Betting odds meaning refers to the numerical expression of an event’s probability and potential payout. Odds help bettors understand possible winnings and risks. Learning how to read betting odds is crucial for making informed bets. Betting odds are explained in simple terms: they indicate how much you can win based on your wager.
Types of odds
There are three main types of betting odds: decimal, fractional, and American. Decimals are common in Europe and show the total payout per unit wagered (e.g., 2.50 means a $10 bet returns $25). Fractional, used in the UK, represents profit relative to the stake (e.g., 5/1 means a $10 bet wins $50). American odds use positive and negative numbers (+200 means a $100 bet wins $200, and -150 means you must bet $150 to win $100).
However, you may also encounter Hong Kong, Indonesian, and Malaysian odds in some regions.
Here’s how it works:
| Odds format | Example odds | Implied probability (%) | Potential Profit on $100 Bet | Total Payout on $100 Bet | Notes |
| Decimal | 2.50 | 40% | $150 | $250 | Most common worldwide, easy to calculate payout |
| Fractional | 3/2 | 40% | $150 | $250 | Popular in the UK, shows profit relative to stake |
| American | +150 | 40% | $150 | $250 | Used mainly in the US, positive and negative values |
| Hong Kong | 1.50 | 40% | $150 | $250 | Similar to decimal but only shows profit |
| Indonesian | +1.50 | 40% | $150 | $250 | Works like American odds but in fractional format |
| Malaysian | +0.75 | 40% | $75 | $175 | Unique − positive values return less profit, negative ones return full stake |
How are odds calculated?
Understanding how betting odds are calculated is important for making informed bets. Bookmakers set them based on probabilities and market trends and balance their books to ensure profit.
Decimal odds
Decimals are the easiest to understand. The formula is:
Payout = Stake × Odds
For example, if a team has decimal odds of 2.50 and you bet $100, your total payout will be:
100 × 2.50 = 250
This includes your original stake, so the net profit is $150.
Fractional odds
Fractionals are popular in the UK and show potential profit relative to the stake. The formula is:
Profit = (Stake × Numerator) / Denominator
For example, with 5/1 odds, if you bet $100, your profit will be:
(100 × 5) / 1 = 500
Total payout = $600.
If the odds are 7/4, the calculation is:
(100 × 7) / 4 = 175
Total payout = $275.
American odds
American odds use positive and negative values:
- Positive odds (+) show how much profit you make on a $100.
- Negative odds (-) show how much you must bet to win $100.
Example 1: Positive Odds (+200)
A +200 bet means you win $200 for every $100 wagered. If you bet $50:
50 × (200 / 100) = 100
Total payout = $150.
Example 2: Negative Odds (-150)
A -150 bet means you must wager $150 to win $100. If you bet $75:
75 / (150×100)=50
Total payout = $125.
Odds fluctuate due to team performance, injuries, volume. If many bettors place money on one side, bookmakers adjust the odds to balance risk. This is why in-play betting odds shift constantly.
Knowing how to calculate odds helps bettors compare potential profits, assess risk, and develop smarter strategies. Bookmakers adjust betting lines based on market movement, so understanding these calculations can give bettors an edge.
How to read betting odds?
You need to understand how to read betting odds to make smart bets. They indicate both the potential payout and the implied probability of an outcome. The lower the odds, the higher the chance of winning, but the smaller the returns − and vice versa.
Bookmakers use three formats to display odds: decimal, fractional, and American. While they look different, they all represent the same thing: how much you will receive if your bet wins.
How to interpret betting lines?
- Lower odds (e.g., 1.50, 1/2, -200) = higher probability, lower profit.
- Higher odds (e.g., 5.00, 4/1, +400) = lower probability, higher profit.
- Odds change due to player bets, team news, and other factors.
For example, if you see odds of 2.00, the probability is estimated at 50%, and a win doubles your stake. If the odds are 4.50, a victory will return 4.5x your bet, but the likelihood of this outcome is lower.
Understanding odds helps you assess risk and choose better bets. Now that you know how to read them, it’s time to move on to strategies!
How to use odds for betting strategies?
Odds are the foundation of any betting strategy. They indicate probability and help bettors assess risk, potential profit, and value. A smart bettor knows how to read odds, find opportunities, and use available bonuses to increase their chances of success.
How to choose bets based on odds?
Making smart bets starts with understanding how chances shift and where value lies. Skilled bettors compare odds across markets to find discrepancies and capitalize on bookmakers’ miscalculations in probability.

Estimation of potential profit
Your potential payout isn’t just determined by the odds − it’s also influenced by things like market trends, limits, and the bookmaker’s margin. To help with this, many betting platforms, including 1xBet, offer bet calculators. These tools let users quickly check how much they could win based on their stake and the current odds, making it easier to plan bets.
Key factors affecting profit calculation
- Odds type. Decimal, fractional, and American odds influence how payouts are structured.
- Bet type. Single, accumulators, and system bets yield different returns.
- Stake amount. Higher stakes lead to bigger winnings but also greater risk.
- Bookmaker margin. Hidden within odds, it ensures the bookmaker retains a small percentage of bets.
- Cash-out feature. Some sportsbooks allow early cash-outs to lock in a profit or minimize losses.
Understanding odds, risk, and available promotions can help bettors make smarter choices and develop a long-term strategy. Those who take the time to analyze these factors put themselves in a better position for consistent success.
Common mistakes when reading odds
Even experienced bettors sometimes misread odds, which can lead to poor decisions. Here are some common pitfalls and how to avoid them:
- Misunderstanding probability
Many assume that high odds mean something is unlikely to happen, but odds only represent implied probability, not certainty. Always check if the odds align with actual chances before placing a bet. - Mixing up odds formats
Bookmakers display odds in different formats (decimal, fractional, American), and confusion between them can lead to miscalculations. Make sure you’re using the format you’re most comfortable with. - Forgetting about the bookmaker’s margin
Odds don’t always reflect true probability − bookmakers include a margin to ensure a profit. Comparing odds from different sportsbooks can help you find better value bets. - Ignoring live odds changes
Odds shift during games due to team performance, injuries, and trends. Not paying attention to these updates can mean missing out on good opportunities. - Misjudging potential payouts
A simple miscalculation can lead to unexpected losses. Always double-check your stake and bet type, and when in doubt, use a bet calculator to confirm potential winnings.
FAQ
What do negative and positive odds mean in sports betting?
In sports betting, odds can be positive (+) or negative (-), indicating the potential payout and the probability of an outcome.
- Positive odds (+): These represent the potential profit on a $100 bet. If you see +200, you win $200 for every $100 wagered, plus you get your original stake back. Higher positive odds indicate a less likely outcome but a bigger payout.
- Negative odds (-): These show how much you need to bet to win $100. If the odds are -150, you must bet $150 to win $100. Lower negative odds suggest a higher probability of winning, but the payouts are smaller.
In short, positive odds are for underdogs with higher risk but bigger rewards, while negative odds are for favorites with safer bets but lower returns. Understanding this helps bettors make informed decisions.
What is the best formula for betting?
There is no universal formula that guarantees success in sports betting. While many bettors look for a winning strategy, betting always involves risk, and even the most calculated approach cannot predict outcomes with certainty.
However, successful bettors rely on key principles:
- Value betting. Finding odds where the probability is higher than the bookmaker suggests.
- Bankroll management. Setting a budget and not exceeding it, regardless of wins or losses.
- Kelly criterion. A mathematical approach that helps determine optimal bet sizing based on perceived value.
- Odds comparison. Checking different bookmakers to find the best odds for maximum profit.
These strategies can help you make better decisions, but no method can guarantee wins. The key to smart betting is staying informed, setting realistic expectations, and acting responsibly.
Is there a best type of odds to use for beginners?
The best type of odds for beginners depends on what feels easiest to understand. Decimal odds are often recommended because they clearly show the total return per unit wagered, making calculations simple. However, some bettors find fractional or American odds more intuitive based on their familiarity with betting formats. The key is to choose the format that makes reading and comparing odds effortless. Most platforms allow users to switch between formats so beginners can experiment and find what works best for them.
What is the easiest way to calculate odds?
The easiest way is to use a bet calculator, which instantly shows potential payouts. If calculating manually, decimal odds are the simplest − multiply your stake by the odds to get the total return. Many betting platforms also offer built-in tools to make the process effortless.
What happens if odds change after a bet?
If the odds change after you’ve placed a bet, your original odds stay locked in. The payout will be based on the odds at the time of your bet, not the updated ones. Odds shifts only affect new bets, so it won’t be adjusted once yours is confirmed.
Where do bookmakers get their odds?
Bookmakers set odds using statistical models, expert analysis, and market trends. They factor in team performance, injuries, historical data, and betting patterns. Odds are constantly adjusted based on new information and the money coming in on different outcomes.
Conclusion
Knowing how betting odds work is essential for making informed bets. Whether you prefer decimal, fractional, or American odds, understanding them helps you calculate potential winnings and avoid common mistakes. Using smart strategies and taking advantage of promo codes can make the experience even more rewarding.
