If you are new to sports betting, understanding betting odds is one of the first things you should learn. Odds show the potential return from a successful wager and give you an indication of how a bookmaker has priced a particular outcome.
Among the different odds formats available, decimal odds are one of the easiest for beginners to understand. The number represents the total return for every unit staked, including the original stake.
For example, decimal odds of 2.50 mean that a $10 winning bet would return $25 in total. This includes the original $10 stake, giving you a potential profit of $15.
Whether you are interested in football, basketball, tennis, cricket, esports or other sports, knowing how decimal odds work can help you understand betting markets and calculate potential returns before placing a wager.
This guide explains decimal odds in detail, including how to calculate winnings, understand implied probability, compare different odds formats, use decimal odds in accumulator bets and explore sports betting markets with Dafabet.
What Are Decimal Odds?
Decimal odds are a numerical format used by bookmakers to display the potential total return from a winning bet.
The basic formula is:
Total Return = Stake × Decimal Odds
For example, if you place a $20 bet at 2.50 odds:
$20 × 2.50 = $50
Your total return would be $50, including your original $20 stake.
Your potential profit would therefore be:
$50 − $20 = $30
Decimal odds can appear as numbers such as 1.20, 1.50, 2.00, 2.50, 3.00, 5.00 or 10.00.
Why Are Decimal Odds Easy to Understand?
One of the main advantages of decimal odds is that you can calculate the total return using a simple multiplication.
For example:
- 1.50 means 1.5 times your stake
- 2.00 means twice your stake
- 3.00 means three times your stake
- 5.00 means five times your stake
This makes decimal odds particularly convenient for beginners.
How Do Decimal Odds Work?
Decimal odds work as a multiplier applied to your stake.
Suppose a football team is offered at 1.80.
If you stake $10:
$10 × 1.80 = $18 total return
Your potential profit would be $8.
If you stake $50 at the same odds:
$50 × 1.80 = $90 total return
Your potential profit would be $40.
The odds stay the same, while your potential return changes depending on the amount you stake.
Decimal Odds Example
Imagine a football match has the following prices:
| Selection | Decimal Odds |
| Home Team | 1.70 |
| Draw | 3.80 |
| Away Team | 4.80 |
If you choose the home team at 1.70 and stake $20:
$20 × 1.70 = $34 total return
Your potential profit would be $14.
The calculation can be completed before placing the bet, allowing you to understand the potential outcome.
How to Calculate Potential Winnings
There are two formulas every beginner should know.
Calculating Total Return
Stake × Decimal Odds = Total Return
For example:
$25 × 2.40 = $60
The total potential return is $60.
Calculating Potential Profit
To calculate profit, subtract your original stake:
(Stake × Decimal Odds) − Stake = Potential Profit
Using the previous example:
$60 − $25 = $35
Your potential profit would be $35.
Decimal Odds Examples for Different Stakes
The same odds can produce very different returns depending on your stake.
Suppose the odds are 3.00:
| Stake | Total Return | Potential Profit |
| $5 | $15 | $10 |
| $10 | $30 | $20 |
| $25 | $75 | $50 |
| $50 | $150 | $100 |
| $100 | $300 | $200 |
This demonstrates why setting a betting budget is important. Increasing your stake increases both the potential return and the amount of money you have at risk.
What Do Low Decimal Odds Mean?
Low decimal odds generally indicate that a selection is considered more likely to win than selections with higher odds.
Examples include:
- 1.15
- 1.25
- 1.40
- 1.50
- 1.60
A favourite priced at 1.25 could provide a relatively small profit compared with a selection priced at 5.00.
However, low odds do not mean guaranteed success. A heavily favoured team or player can still lose.
Example of Low Odds
A $100 stake at 1.25 would produce:
$100 × 1.25 = $125 total return
The potential profit would be $25.
Although the potential profit is relatively small compared with the stake, the bet still carries risk.
What Do High Decimal Odds Mean?
Higher decimal odds generally represent selections that the market considers less likely to win.
Examples include:
- 3.00
- 5.00
- 10.00
- 20.00
At 10.00 odds, a $10 winning bet would return $100 in total, including $90 profit.
Higher Odds Do Not Automatically Mean Better Value
A common beginner mistake is assuming that high odds are always attractive because the potential payout is larger.
However, higher odds generally correspond to a lower implied probability.
A large potential payout does not mean an outcome is likely to happen.
What Does 2.00 Decimal Odds Mean?
2.00 odds are particularly easy to understand.
A $10 stake would produce:
$10 × 2.00 = $20 total return
The potential profit would be $10.
The implied probability represented by 2.00 odds is 50%, before considering the bookmaker’s margin.
What Does 1.00 Decimal Odds Mean?
Odds of 1.00 mean that there is no additional profit.
For example:
$20 × 1.00 = $20
You would receive your original stake back if the bet were settled at those odds.
Standard betting markets generally feature odds above 1.00.
Understanding Decimal Odds and Implied Probability
Decimal odds can be converted into an implied probability.
The basic formula is:
Implied Probability = 1 ÷ Decimal Odds × 100
For example, if the odds are 2.50:
1 ÷ 2.50 × 100 = 40%
This means 2.50 odds correspond to an implied probability of 40%.
Common Decimal Odds and Their Implied Probability
| Decimal Odds | Implied Probability |
| 1.20 | 83.33% |
| 1.50 | 66.67% |
| 2.00 | 50% |
| 2.50 | 40% |
| 3.00 | 33.33% |
| 4.00 | 25% |
| 5.00 | 20% |
| 10.00 | 10% |
These figures should not be interpreted as guarantees or necessarily as the true probability of the event.
What Is the Bookmaker’s Margin?
Bookmakers generally include a margin when creating betting markets.
This margin is sometimes called the overround or bookmaker’s margin.
If you convert all selections in a market into implied probabilities and add them together, the total will often be greater than 100%.
This difference helps explain how bookmakers build their margin into markets.
Why Does the Margin Matter?
Understanding the bookmaker’s margin can help bettors recognise that the odds are not simply a neutral prediction of an event.
They represent a price offered by the bookmaker based on its assessment of probability, market conditions and other factors.
How Do Bookmakers Set Decimal Odds?
Bookmakers use statistical models, market information and other data when setting odds.
Factors can include:
- Recent form
- Historical performance
- Injuries
- Suspensions
- Player availability
- Home advantage
- Head-to-head records
- Team statistics
- Market activity
- Public betting patterns
- Weather conditions
Odds can change when new information becomes available.
Why Do Odds Change?
A bookmaker may adjust odds after receiving new information.
For example, if a football team’s key striker is ruled out before a match, the odds for that team may change.
Odds can also move because of changes in betting activity or developments during live events.
Decimal Odds for Different Sports
Decimal odds can be used across many different sports and competitions.
Football Betting
Football markets can include:
- Match winner
- Both teams to score
- Total goals
- Handicap
- Correct score
- Half-time result
Tennis Betting
Tennis markets can include:
- Match winner
- Set winner
- Total games
- Game handicap
- Correct score
Basketball Betting
Basketball markets may include:
- Match winner
- Point spread
- Total points
- Quarter markets
- Player markets
Cricket Betting

- Match winner
- Top batsman
- Top bowler
- Total runs
- Innings markets
Esports Betting
Esports markets can include:
- Match winner
- Map winner
- Map handicap

The exact markets and odds available can vary by event and bookmaker.
Decimal Odds in Accumulator Bets
Decimal odds are particularly useful for accumulator bets.
An accumulator combines several selections into one wager.
For example:
- Football selection: 1.50
- Tennis selection: 1.80
- Basketball selection: 2.00
The combined odds would be:
1.50 × 1.80 × 2.00 = 5.40
A $10 stake would therefore have a potential total return of:
$10 × 5.40 = $54
The potential profit would be $44.
Why Are Accumulators Riskier?
While accumulators can provide larger potential returns, every selection generally needs to be successful.
If one required selection loses, the standard accumulator will generally lose.
For this reason, beginners should understand individual bets before experimenting with multiple selections.
Single Bets vs Accumulator Bets
A single bet contains one selection, while an accumulator contains multiple selections.
Single Bet Example
Team A at 2.00 with a $10 stake:
$10 × 2.00 = $20
Accumulator Example
Three selections:
- 1.50
- 2.00
- 2.50
Combined odds:
1.50 × 2.00 × 2.50 = 7.50
A $10 stake would have a potential return of $75.
The accumulator offers a higher potential payout but also introduces additional risk.
Decimal Odds and Handicap Betting
Handicap betting adds a theoretical advantage or disadvantage to a team or player.
For example, a basketball team may be offered at:
Team A -4.5 at 1.90
The bet may require Team A to win by five or more points for the selection to be successful.
Handicap rules vary between sports and markets, so always check the specific settlement conditions before placing a wager.
Decimal Odds and Over/Under Markets
Over/under markets allow bettors to predict whether a particular statistic will be above or below a specified line.
For example:
Over 2.5 Goals — 1.90
A successful bet would generally require three or more goals.
Under 2.5 Goals — 1.90
A successful bet would generally require two or fewer goals.
The exact settlement rules can vary, so beginners should always review the market conditions.
Pre-Match Decimal Odds
Pre-match odds are available before an event begins.
This gives bettors time to research relevant information such as:
- Team form
- Player availability
- Injuries
- Statistics
- Recent performances
- Competition standings
Pre-match betting can be useful for beginners because there is generally more time to review a selection before confirming a wager.
Live Betting and Decimal Odds
Decimal odds can also change during a live event.
For example, if a football team scores, its odds may shorten while the opposing team’s odds may lengthen.
Live odds can move rapidly because the circumstances of the event are changing continuously.
Why Beginners Should Be Careful With Live Betting
Live betting can encourage fast decisions.
If you are new to betting, take time to understand how live markets work before using them.
Never feel pressured to place a wager simply because odds have changed.
Comparing Decimal Odds
Comparing prices can help you understand how different odds affect potential returns.
Suppose the same selection is offered at:
- Bookmaker A: 1.80
- Bookmaker B: 1.90
With a $100 stake:
1.80 = $180 total return
1.90 = $190 total return
The second price provides a higher potential return for the same stake.
However, price should not be the only consideration. Market rules, availability, limits and other conditions can also matter.
Common Beginner Mistakes With Decimal Odds
Mistake 1: Confusing Profit and Return
Remember that total return includes your original stake.
Mistake 2: Assuming Short Odds Are Guaranteed
A 1.20 favourite can still lose.
Mistake 3: Choosing High Odds Just for the Payout
High odds may offer an attractive potential return but generally indicate greater uncertainty.
Mistake 4: Ignoring Market Conditions
Always understand exactly what needs to happen for your selection to win.
Mistake 5: Chasing Losses
Increasing your stake to recover a previous loss can lead to even larger losses.
Mistake 6: Betting Without a Budget
Set your limits before you start betting.
How to Create a Simple Betting Budget
Responsible bankroll management is an important part of sports betting.
Choose an amount that you can comfortably afford to lose and treat it as entertainment spending rather than guaranteed income.
Simple Budget Rules
You can consider rules such as:
- Never use money needed for bills.
- Never borrow money to bet.
- Set weekly or monthly limits.
- Avoid increasing stakes after losses.
- Keep individual wagers affordable.
- Stop when you reach your predetermined limit.
A betting budget should always be based on money you can afford to lose.
How to Keep Track of Your Bets
Keeping a betting record can help you understand your activity.
You can record:
- Date
- Sport
- Competition
- Selection
- Odds
- Stake
- Result
- Profit or loss
Example Betting Record
| Date | Sport | Odds | Stake | Result |
| Sept 1 | Football | 1.80 | $10 | Win |
| Sept 2 | Tennis | 2.20 | $10 | Loss |
| Sept 3 | Basketball | 1.90 | $10 | Win |
Tracking results can help you avoid relying solely on memory and make it easier to monitor your betting budget.

Why Starting Small Can Help Beginners
There is no reason to start with large stakes when learning how betting works.
Small wagers can help you become familiar with:
- Decimal odds
- Betting slips
- Different markets
- Potential returns
- Bet settlement
- Bankroll management
The goal at the beginning should be to understand the process rather than chase large payouts.
How to Avoid Emotional Betting
Sports fans often have favourite teams and players.
However, emotional attachment can influence betting decisions.
For example, you might support a particular football club and automatically bet on it even when the odds or circumstances do not appeal to you.
Questions to Ask Before Betting
Before confirming a wager, ask:
- Do I understand this market?
- Have I checked the relevant information?
- Do I understand the odds?
- Is the stake within my budget?
- Am I betting because of analysis or emotion?
- Would I still place this bet without a personal connection to the team?
Taking a moment to think can help reduce impulsive decisions.
Understanding Risk and Reward
Sports betting always involves a relationship between potential reward and risk.
Lower odds generally provide smaller potential profits, while higher odds provide larger potential profits.
For example:
Bet A: $50 at 1.40
Potential return: $70
Potential profit: $20
Bet B: $50 at 4.00
Potential return: $200
Potential profit: $150
Bet B offers a larger potential return, but its higher odds generally indicate a lower implied probability.
Neither option guarantees a successful result.
What Is Expected Value?
Once you understand basic decimal odds, you may encounter the term expected value, or EV.
Expected value is a mathematical concept used to estimate the potential long-term value of a wager based on an estimated probability.
For example, if you believe an outcome has a 50% chance of occurring and the available odds are 2.20, you could compare your estimated probability with the probability implied by the odds.
However, accurately estimating probability is difficult.
Expected value is therefore not a guarantee that an individual bet will win.
Understanding Odds Movement
Odds can move before and during sporting events.
For example:
2.50 → 2.20
means the odds have shortened.
Alternatively:
2.50 → 2.80
means the odds have lengthened.
Why Do Odds Move?
Possible reasons include:
- New injury information
- Team lineup announcements
- Changes in weather
- Betting activity
- Market expectations
- Developments during live events
Do not assume that every odds movement indicates which team or player will eventually win.
Responsible Sports Betting
Understanding decimal odds can help you make more informed decisions, but it cannot remove the financial risk involved in betting.
Always remember:
- Bet only with money you can afford to lose.
- Never borrow money to bet.
- Set a betting budget.
- Avoid chasing losses.
- Take breaks when needed.
- Don’t treat betting as guaranteed income.
- Don’t bet under pressure.
- Understand the market before placing a wager.
If betting stops being enjoyable or becomes difficult to control, stop betting and seek appropriate support.
Final Thoughts on Decimal Odds
Decimal odds are one of the simplest betting formats to learn.
The most important formula to remember is:
Stake × Decimal Odds = Total Return
Once you understand this calculation, you can begin exploring more advanced concepts such as implied probability, bookmaker margins, handicaps, over/under markets and accumulators.
Dafabet users can apply this knowledge when exploring available sports betting markets and comparing potential returns.
If you’re ready to try sports betting, start with a sport you understand, choose a market you are familiar with and consider a small wager that fits comfortably within your budget.
Bet for entertainment, stay within your limits and remember that no odds guarantee a winning result.
