What Are Betting Odds?

Betting odds represent the probability of an event occurring and determine how much you can win on a bet. Sportsbooks express odds in three main formats: American (moneyline), Decimal (European), and Fractional (British). Each format displays the same information differently, but all tell you the potential return on your wager.

Understanding odds is fundamental to sports betting success. Odds not only indicate potential payouts but also reveal the implied probability—the bookmaker's assessment of how likely an outcome is to occur. Learning to read and compare odds across formats helps you identify value bets and make informed betting decisions.

American Odds (Moneyline)

American odds, also called moneyline odds, use positive and negative numbers to indicate favorites and underdogs. This is the standard format used by sportsbooks in the United States.

Positive American Odds (Underdogs)

Positive odds (e.g., +150, +200, +350) show how much profit you would make on a $100 bet. The higher the positive number, the greater the underdog and potential profit.

Positive American Odds Payout Formula:

\[ \text{Profit} = \text{Stake} \times \frac{\text{American Odds}}{100} \] \[ \text{Total Payout} = \text{Stake} + \text{Profit} \]

Example: +150 Odds with $100 Bet

• Profit = $100 × (150/100) = $150

• Total Payout = $100 + $150 = $250

Interpretation: For every $100 wagered, you win $150 profit if your bet succeeds.

Negative American Odds (Favorites)

Negative odds (e.g., -110, -150, -250) show how much you must bet to win $100 profit. The higher the negative number, the stronger the favorite and the more you must risk for the same profit.

Negative American Odds Payout Formula:

\[ \text{Profit} = \text{Stake} \times \frac{100}{|\text{American Odds}|} \] \[ \text{Total Payout} = \text{Stake} + \text{Profit} \]

Example: -150 Odds with $150 Bet

• Profit = $150 × (100/150) = $100

• Total Payout = $150 + $100 = $250

Interpretation: You must bet $150 to win $100 profit if your bet succeeds.

Decimal Odds (European)

Decimal odds are the simplest format to understand and the most popular globally. They represent the total return (profit plus stake) per unit wagered. Decimal odds are always expressed as a number greater than 1.00.

Decimal Odds Payout Formula:

\[ \text{Total Payout} = \text{Stake} \times \text{Decimal Odds} \] \[ \text{Profit} = \text{Total Payout} - \text{Stake} \]

Example: 2.50 Decimal Odds with $100 Bet

• Total Payout = $100 × 2.50 = $250

• Profit = $250 - $100 = $150

Interpretation: For every $1 wagered, you receive $2.50 back (including your original stake).

Why Decimal Odds Are Popular

Decimal odds simplify payout calculations because you multiply your stake by the odds to get your total return. There's no need to add your stake back—it's already included in the decimal number. This makes parlay calculations and quick mental math much easier.

Fractional Odds (British)

Fractional odds, traditional in the United Kingdom and Ireland, express the profit relative to your stake as a fraction. The numerator (top number) shows potential profit, while the denominator (bottom number) shows the required stake.

Fractional Odds Payout Formula:

\[ \text{Profit} = \text{Stake} \times \frac{\text{Numerator}}{\text{Denominator}} \] \[ \text{Total Payout} = \text{Stake} + \text{Profit} \]

Example: 3/2 Fractional Odds with $100 Bet

• Profit = $100 × (3/2) = $150

• Total Payout = $100 + $150 = $250

Interpretation: For every $2 wagered, you win $3 profit.

Reading Fractional Odds

When the numerator is larger than the denominator (e.g., 5/1, 3/2, 7/4), the outcome is an underdog. When the denominator is larger (e.g., 1/2, 2/5, 1/3), the outcome is a favorite. Odds of 1/1 (even money) mean equal profit and stake.

Converting Between Odds Formats

Understanding how to convert between odds formats is essential when comparing bets across different sportsbooks or international betting markets. Here are the conversion formulas for all three formats.

American to Decimal Conversion

Conversion Formulas:

\[ \text{Positive American: Decimal} = \frac{\text{American}}{100} + 1 \] \[ \text{Negative American: Decimal} = \frac{100}{|\text{American}|} + 1 \]

Conversion Examples:

• +150 → (150/100) + 1 = 2.50

• -150 → (100/150) + 1 = 1.67

• +200 → (200/100) + 1 = 3.00

• -250 → (100/250) + 1 = 1.40

Decimal to American Conversion

Conversion Formulas:

\[ \text{If Decimal} \geq 2.00: \text{American} = (\text{Decimal} - 1) \times 100 \] \[ \text{If Decimal} < 2.00: \text{American} = \frac{-100}{\text{Decimal} - 1} \]

Fractional to Decimal Conversion

Conversion Formula:

\[ \text{Decimal} = \frac{\text{Numerator}}{\text{Denominator}} + 1 \]

Example: 3/2 → (3/2) + 1 = 2.50

Decimal to Fractional Conversion

Conversion Steps:

\[ \text{Step 1: } \text{Decimal} - 1 = \text{Decimal Fraction} \] \[ \text{Step 2: Convert to simplest fraction form} \]

Example: 2.50 → 2.50 - 1 = 1.50 = 3/2

Implied Probability

Implied probability is the conversion of betting odds into a percentage representing the likelihood of an event occurring according to the sportsbook. Understanding implied probability helps you identify value bets where your assessed probability differs from the bookmaker's odds.

Calculating Implied Probability

Implied Probability from Decimal Odds:

\[ \text{Implied Probability} = \frac{1}{\text{Decimal Odds}} \times 100\% \]

Implied Probability from American Odds:

\[ \text{Positive: } \frac{100}{\text{American Odds} + 100} \times 100\% \] \[ \text{Negative: } \frac{|\text{American Odds}|}{|\text{American Odds}| + 100} \times 100\% \]

Implied Probability Examples:

• Odds of 2.00 (decimal) = 50% implied probability

• Odds of +150 (American) = 40% implied probability

• Odds of -150 (American) = 60% implied probability

• Odds of 3.00 (decimal) = 33.33% implied probability

Using Implied Probability for Value Betting

Compare the implied probability to your own assessment of an event's likelihood. If you believe an outcome is more likely than the implied probability suggests, that bet has positive expected value. For example, if odds imply 40% probability but you assess 50% chance, that's a value bet.

Understanding The Vig (Juice)

The "vig" or "juice" is the sportsbook's commission built into betting odds. It ensures the bookmaker profits regardless of outcome. Understanding the vig helps you recognize the true odds and calculate expected value.

Example of the Vig:

Standard point spread odds are -110 on both sides:

• Team A -7.5 at -110 (52.38% implied probability)

• Team B +7.5 at -110 (52.38% implied probability)

• Combined: 52.38% + 52.38% = 104.76%

The extra 4.76% represents the bookmaker's edge. In a fair market, both sides would total exactly 100%. The difference is the vig—the price you pay for the bookmaker's services.

Calculating No-Vig Odds

No-Vig Probability Formula:

\[ \text{No-Vig Prob} = \frac{\text{Implied Probability}}{\text{Total Implied Probability}} \times 100\% \]

Common Betting Odds Scenarios

Even Money (+100 or 2.00)

Even money means your profit equals your stake. A $100 bet at even odds wins $100 profit for a total payout of $200. This represents exactly 50% implied probability in a fair market.

Standard Point Spread (-110)

The -110 odds are standard for NFL and NBA point spreads. You must risk $110 to win $100. This slight favorite pricing (52.38% implied probability) includes the sportsbook's vig on both sides of the bet.

Heavy Favorites (-300 to -500)

Large negative numbers indicate strong favorites. At -400, you must risk $400 to win $100 (80% implied probability). While favorites win more often, the risk-reward ratio is unfavorable—large stakes for modest profits.

Long Shots (+500 to +5000)

High positive numbers represent unlikely outcomes with large potential payouts. At +1000, a $100 bet wins $1,000 profit (9.09% implied probability). Long shots offer excitement but win infrequently—discipline is essential.

Frequently Asked Questions

How do I calculate my betting payout?

Multiply your stake by the decimal odds to get total payout, then subtract your stake to find profit. For American odds: if positive, multiply stake by (odds/100); if negative, multiply stake by (100/|odds|). For fractional odds, multiply stake by (numerator/denominator). Our calculator handles all formats automatically.

What does +150 mean in betting?

+150 means if you bet $100, you would win $150 profit for a total payout of $250. Positive American odds show how much profit you make on a $100 bet. The higher the positive number, the greater the underdog and potential profit. +150 represents approximately 40% implied probability.

What does -110 mean in betting?

-110 means you must bet $110 to win $100 profit for a total payout of $210. Negative American odds show how much you need to bet to win $100. -110 is the standard odds for point spreads and totals, representing 52.38% implied probability with the bookmaker's vig included.

Which odds format is easiest to understand?

Decimal odds are generally easiest because they show your total return directly. Simply multiply your stake by the decimal odds (e.g., $100 × 2.50 = $250 total payout). American odds require different calculations for positive and negative numbers, while fractional odds involve fraction arithmetic.

How do you convert American odds to decimal?

For positive American odds, divide by 100 and add 1 (e.g., +150 → 150/100 + 1 = 2.50). For negative American odds, divide 100 by the absolute value and add 1 (e.g., -150 → 100/150 + 1 = 1.67). Our calculator converts automatically between all formats.

What is implied probability in betting odds?

Implied probability is the likelihood of an event occurring according to the betting odds, expressed as a percentage. Calculate it by dividing 1 by decimal odds and multiplying by 100. For example, 2.00 decimal odds = 50% implied probability. This helps identify value bets where your assessment differs from the bookmaker's.

What is the vig or juice in sports betting?

The vig (vigorish) or juice is the bookmaker's commission built into the odds. It's why point spread odds are typically -110 on both sides instead of even money. The combined implied probabilities exceed 100%, with the excess representing the bookmaker's profit margin. Standard vig on -110 odds is approximately 4.5%.

Do you get your stake back when you win a bet?

Yes, when you win a bet, you receive both your profit and your original stake back. The "total payout" includes everything. For example, a $100 bet at +150 pays $150 profit plus your $100 stake = $250 total payout. Some displays show only the profit ($150), while others show total payout ($250).

What are fractional odds and how do they work?

Fractional odds (e.g., 3/2, 5/1) show profit relative to stake. The first number (numerator) is your profit, and the second (denominator) is your stake. Odds of 3/2 mean you win $3 for every $2 bet. A $100 bet at 3/2 would win $150 profit plus your $100 stake = $250 total payout.

Can betting odds change after I place my bet?

The odds you receive when placing your bet are locked in—that's your payout rate regardless of future odds changes. However, odds do change based on betting action, news, injuries, and other factors. If you bet at +150 and odds later move to +200, you keep your +150 odds. This is why timing your bets strategically matters.
