What does -110 odds mean in sports betting?
-110 odds in sports betting indicate that you must wager $110 to win $100, reflecting a standard bookmaker margin.
These odds are common in point spread and moneyline bets, showing the bookmaker’s built-in commission or 'vig'.
While traditional betting involves managing this margin and risk, arbitrage betting eliminates guesswork by securing guaranteed profits regardless of outcomes.
Understanding Negative Odds (-110) in Sports Betting
Negative odds like -110 tell you how much you must bet to win a fixed amount, typically $100. In this case, betting $110 wins you $100 plus your original stake back. This format is common in American odds and reflects the bookmaker's commission, ensuring they profit over time.
- •-110 means you risk $110 to win $100
- •Commonly used in point spread betting
- •Reflects bookmaker’s margin or 'vig'
Why Bookmakers Use -110 Odds
Bookmakers set odds like -110 to balance their books and guarantee profit regardless of which side wins. This margin covers operational costs and reduces risk from uneven betting volumes.
- →Ensures bookmaker profitability
- →Encourages equal betting on both sides
- →Creates a predictable margin
💡Calculating Profit at -110 Odds
If you bet $110 on a team at -110 odds and they win, you receive $210 back — your original $110 stake plus $100 profit.
Profit = (Stake / 110) * 100; Profit = (110 / 110)*100 = $100
Comparing -110 Odds with Other Formats
American odds like -110 can be converted into decimal or fractional odds for easier comparison. Decimal odds express total return per dollar wagered, while fractional odds show profit relative to stake. Understanding these helps bettors compare value across sportsbooks.
- •-110 odds equal 1.91 decimal odds
- •Equivalent fractional odds are 10/11
- •Different formats help international bettors understand risk and reward
How Arbitrage Benefits from Multiple Odds Formats

- →Automates complex conversion and calculation
- →Maximizes guaranteed profit potential
Risks of Betting at Standard -110 Odds
While -110 odds are straightforward, they carry inherent risks such as losing your entire stake if your selection fails. The bookmaker’s margin also means you must win more than 52.4% of your bets to break even. This makes consistent profit challenging without a strategy.
- •You must risk more than you can win
- •Bookmaker’s vig reduces expected value
- •High risk if win rate is below break-even
How Arbitrage Betting Eliminates These Risks
Arbitrage betting removes these risks by simultaneously placing bets on all possible outcomes with different sportsbooks at favorable odds. This guarantees a profit regardless of the outcome, eliminating guesswork and exposure to loss.
- →No risk of losing stake
- →Profit is locked in before the event starts
- →Ideal for risk-averse bettors
Calculating Implied Probability from -110 Odds
Implied probability represents the chance the bookmaker assigns to an outcome. For -110 odds, the formula is Stake / (Stake + Profit), which equals 110 / (110 + 100) = 52.38%. This slightly overstates the true chance due to the bookmaker’s margin.
- •Implied probability for -110 is about 52.38%
- •Sum of implied probabilities for both sides exceeds 100%
- •The excess represents bookmaker’s margin
Using Implied Probability to Find Value
Smart bettors look for odds that represent a probability lower than the true chance of winning, indicating value. However, identifying value can be complex. Arbitrage betting circumvents this by focusing solely on odds discrepancies to guarantee profit.
- →Value betting requires accurate probability estimates
- →Arbitrage bypasses the need for prediction
- →Software tools can help identify value and arbitrage
💡Implied Probability Calculation for -110
Calculate implied probability: 110 / (110 + 100) = 0.5238 or 52.38%. This means the bookmaker implies a 52.38% chance of winning for the outcome.
Implied Probability = Stake / (Stake + Profit) = 110 / 210 = 0.5238
Using Arbitrage to Maximize Returns Beyond -110 Odds
Arbitrage betting exploits differences in odds across multiple sportsbooks, often arising around standard -110 lines. By placing bets on all outcomes where combined implied probabilities are less than 100%, bettors lock in guaranteed profits. This method removes the bookmaker’s margin impact.
- •Arbitrage takes advantage of odds discrepancies
- •Profits are secured regardless of match result
- •Reduces reliance on predicting outcomes
How Technology Facilitates Arbitrage
Finding and calculating arbitrage opportunities manually is time-consuming and complex. Tools like ArbitUp automate the process, scanning sportsbooks, converting odds, and calculating stakes needed for guaranteed returns.
- →Automates odds comparison and stake calculation
- →Saves time and reduces errors
- →Empowers bettors to act quickly on opportunities
💡Simple Arbitrage Scenario Around -110 Odds
If one sportsbook offers -110 on Team A and another offers +110 on Team B, a bettor can place stakes on both to guarantee a profit regardless of the winner.
Stake A = $110 at -110 to win $100, Stake B = $100 at +110 to win $110; total stakes $210, guaranteed return $210 or more.
