Comprehensive guide explaining point spreads in sports betting and how arbitrage betting offers a risk-free alternative.
How does a point spread work in sports betting?
A point spread in sports betting is a handicap used to level the playing field between two teams by assigning a margin of points that the favored team must win by or the underdog can lose by for bets to pay out.
Point spreads make betting more competitive and interesting by balancing mismatched teams, requiring bettors to consider the margin of victory or defeat rather than just the winner.
Because predicting exact margins can be challenging, arbitrage betting offers a risk-free way to profit regardless of the point spread outcome.
Understanding Point Spread Basics
The point spread is a number set by oddsmakers to create a balanced betting market. The favorite team is assigned a negative point spread, indicating how many points they must win by, while the underdog receives a positive spread, meaning they can lose by less than that number or win outright for bettors to win.
- •Favorite is denoted with a minus sign (e.g., -7)
- •Underdog is denoted with a plus sign (e.g., +7)
- •Bets on the favorite win only if they cover the spread
- •Bets on the underdog win if they lose by less than the spread or win the game
💡Basic Point Spread Example
If Team A is favored -7 points over Team B (+7), Team A must win by more than 7 points for bets on them to win. If Team A wins by exactly 7 points, the bet is a push and stakes are refunded.
Team A win margin > 7 = favorite wins bet; Team B loss margin < 7 or win = underdog wins bet
How Point Spreads Level the Playing Field
Point spreads are designed to equalize betting interest on both sides by adding a virtual advantage or disadvantage. This helps oddsmakers attract bets on the favorite and underdog evenly, reducing their risk. The spread reflects perceived differences in team strength and situational factors like injuries or home field advantage.
- •Encourages balanced betting volume
- •Reflects team strength and external factors
- •Prevents heavy bias on obvious favorites
- •Makes games with uneven talent more engaging to bet on
Impact on Bettor Strategy
Since the spread affects the margin needed to win a bet, bettors must analyze team performance beyond just winning or losing. This requires deeper insight into scoring trends, defense, and game pace.
- →Consider average winning margins
- →Analyze defensive and offensive matchups
- →Adjust for recent team performance and injuries
💡Leveling Example
A strong team favored by -10 points must win by more than 10 to satisfy bets, while an underdog with +10 can lose by up to 10 points and still win bets. This evens out the betting action.
Favorite margin > 10 = win bets; Underdog margin ≤ 10 = win bets
Calculating Payouts and The Vig
When betting on point spreads, sportsbooks include a commission called the 'vig' or 'juice' in the odds to ensure profit. Typically, bets pay at odds around -110, meaning you must bet $110 to win $100. Understanding how payouts and vig work helps bettors manage risk and potential rewards.
- •Standard odds are often -110 on both sides
- •Vig is how sportsbooks ensure profit regardless of outcome
- •Payout = (stake / odds) * 100 for negative odds
- •Proper bankroll management is essential due to vig
How Arbitrage Betting Helps
While traditional bets include vig and risk losses, arbitrage betting finds opportunities where different sportsbooks have differing spreads or odds, allowing guaranteed profit without risk. This eliminates the impact of vig.
- →Identifies discrepancies in odds across bookmakers
- →Locks in profits regardless of game outcome
- →Avoids losses from vig and incorrect spread predictions
💡Payout Calculation Example
If you bet $110 at -110 odds and win, you receive $210 total ($110 stake + $100 profit). The vig means you pay an extra $10 to win $100.
Payout = $110 + ($110 / 110 * 100) = $210
Common Challenges in Point Spread Betting
Betting on point spreads involves estimating not just the winner but the victory margin, which can be unpredictable due to in-game dynamics, weather conditions, and player performance. This complexity increases risk and requires careful analysis.
- •Difficulty in predicting exact margins
- •Potential for pushes when margins equal the spread
- •Line movements can change betting value
- •Injuries and unexpected events affect outcomes
How Arbitrage Betting Addresses These Risks
Arbitrage betting removes the uncertainty inherent in point spread predictions by leveraging differences in odds to guarantee profit regardless of the margin or winner. Tools like ArbitUp automate finding these opportunities, simplifying the process.
- →Eliminates guesswork about final scores
- →Reduces emotional and financial risk
- →Automates complex calculations with software
💡Line Movement Example
If the spread moves from -7 to -6.5 after heavy betting, odds and value change, complicating decisions. Arbitrage betting can exploit differing lines at various sportsbooks for guaranteed returns.
Use software to identify arbitrage when one sportsbook offers -7 and another -6.5 with favorable odds
Strategies for Successful Point Spread Betting
Successful bettors combine data analysis, timing, and discipline. Monitoring line movements, studying team statistics, and avoiding emotional decisions improve outcomes. Incorporating arbitrage strategies can further reduce risk and lock in profits.
- •Research team trends and matchup history
- •Bet early or late depending on line movement
- •Manage bankroll carefully to withstand variance
- •Use arbitrage tools like ArbitUp to find risk-free opportunities
Using Technology to Your Advantage
Manual calculations for optimal bets can be complex and time-consuming. Arbitrage software automates spotting profitable discrepancies in spreads and odds, making it easier for bettors to capitalize on opportunities.
- →Automates calculations to avoid errors
- →Saves time identifying arbitrage situations
- →Increases consistency and profitability
💡Timing Bet Example
If a bettor notices the spread shifting after key news, placing a bet before the change can maximize value. Combining this with arbitrage ensures profit even if the prediction is off.

Why Arbitrage Betting is Superior to Traditional Point Spread Betting
Traditional point spread betting carries inherent risks due to unpredictability of game outcomes and margins. Arbitrage betting bypasses these uncertainties by capitalizing on market inefficiencies to guarantee profit. This makes it an attractive alternative for those seeking safer, consistent returns.
- •Removes risk related to final score margins
- •Allows profit regardless of which team covers the spread
- •Optimizes use of betting capital effectively
- •Can be automated with tools like ArbitUp for ease
💡Arbitrage Betting Example
If one sportsbook offers Team A at -7 with certain odds and another offers Team B at +7 with differing odds, a bettor can place calculated bets on both sides to ensure profit no matter the margin.
