In tennis betting, the Game Handicap (also known as the Spread) is the second most popular market after the Match Winner. It allows you to bet on a player’s performance relative to the total number of games won, rather than just the final match result. This is perfect for matches with a heavy favorite, where the Moneyline odds offer little value.
However, handicaps can be tricky. A player can win the match but lose the handicap bet, or vice versa. Our Tennis Handicap Calculator helps you analyze the odds for lines like -4.5 or +2.5, revealing the true “Fair Probability” and the hidden margin charged by the sportsbook.

How to Use the Calculator
Handicap markets often have higher margins than standard winner markets. Use this tool to ensure you are getting a fair price:
- Enter the Spread Value: Input the handicap line set by the bookmaker (e.g., -3.5 for the favorite or +3.5 for the underdog).
- Enter the Odds: Input the decimal odds for both the favorite (H1) and the underdog (H2). Usually, these are close to 1.90 on both sides.
- Analyze the Results:
- Fair Probability: See the actual percentage chance of covering the spread, stripped of the bookmaker’s “juice.”
- Margin: Check if the bookmaker is taking a standard cut (5%) or an excessive one (>7%).
If you are looking to bet on the total length of the match rather than the spread, try our Total Games Over/Under Calculator.
Understanding Tennis Spreads with Examples
Unlike football or basketball, tennis scoring is unique. The “Game Handicap” calculates the Total Games Won by each player across the entire match.
Example 1: The Favorite Covers
The Bet: Alcaraz -4.5 Games vs. Evans.
- The Score: Alcaraz wins 6-3, 6-4.
- The Math:
- Alcaraz Games: 6 + 6 = 12
- Evans Games: 3 + 4 = 7
- Difference: 12 – 7 = 5
- Result: Since 5 is greater than 4.5, the -4.5 bet wins.
Example 2: The “Lose Match, Win Bet” Scenario
This is where tennis betting gets interesting. You can back an underdog who loses the match but covers the spread.
The Bet: Underdog +3.5 Games.
- The Score: Favorite wins 7-6, 7-6.
- The Math:
- Favorite Games: 14
- Underdog Games: 12
- Difference: 2
- Result: Since the favorite only won by 2 games, the Underdog (+3.5) covers the spread and wins the bet, even though they lost the match.
Frequently Asked Questions (FAQ)
What is the difference between Set Handicap and Game Handicap?
Game Handicap counts the total games played in the match (e.g., -4.5 games). Set Handicap counts the sets won (e.g., -1.5 sets). A -1.5 Set Handicap means the player must win 2-0 (in a 3-set match) or 3-0/3-1 (in a 5-set match).
What happens if the spread is a whole number (e.g., -4.0)?
If the spread is a whole number and the game difference lands exactly on that number (e.g., the favorite wins by exactly 4 games), the bet is a Push (Void). Your stake is refunded. This is why most lines use half-points (.5) to ensure a result.
Does a tie-break affect the handicap?
Yes. A tie-break counts as one game (the score becomes 7-6). Tie-breaks are often the enemy of handicap bettors backing the favorite, as winning a set 7-6 only yields a +1 game advantage, whereas winning 6-2 yields +4.
