Tennis betting odds can look confusing at first — decimals, fractions, plus-minus numbers — but once you understand them, you gain a huge edge over casual bettors.
In this 2026 complete guide, we break down tennis betting odds step-by-step, explain how bookmakers set prices, how to calculate payouts, and how smart bettors use odds to find value bets.
Whether you’re betting on Grand Slams, ATP, WTA, or live tennis, this guide will help you bet smarter — not harder.
What Are Tennis Betting Odds?
Tennis betting odds represent two things at the same time:
-
Probability of an outcome happening
-
Potential payout if your bet wins
👉 Lower odds = higher chance, lower return
👉 Higher odds = lower chance, higher return
Example:
-
Novak Djokovic @ 1.40 → strong favorite
-
Underdog player @ 3.20 → higher risk, bigger reward
Types of Tennis Betting Odds Explained (2026)
1. Decimal Odds (Most Popular – India & Europe)
Decimal odds show total return, including stake.
Formula:
Example:
-
Bet ₹1,000 @ 2.50
-
Return = ₹2,500 (₹1,500 profit)
✔ Easy to understand
✔ Used by Betacular & top exchanges
✔ Best for beginners
2. Fractional Odds (UK Style)
Written as 5/2, 3/1, 7/4, etc.
Example:
-
Odds 5/2 → For every ₹2, you win ₹5 profit
-
Total return = ₹7
Mostly used in UK sportsbooks, less common in 2026 globally.
3. American Odds (Moneyline Odds)
Shown as +150 or -200
-
+150 → Bet ₹100, win ₹150
-
-200 → Bet ₹200 to win ₹100
Rare for tennis in India but still used on some international sites.
How to Convert Tennis Odds into Probability
Smart bettors always check implied probability.
Formula (Decimal Odds):
Example:
-
Odds: 2.00
-
Probability = 50%
👉 If you believe the player has more than 50% chance, it’s a value bet.
How Bookmakers Set Tennis Odds
Bookmakers use:
-
Player rankings (ATP/WTA)
-
Head-to-head records
-
Surface type (Clay, Grass, Hard)
-
Recent form & injuries
-
Weather & court speed
-
Betting market activity
⚠️ Odds change constantly, especially close to match time.
Live Tennis Odds Explained (In-Play Betting)
Live odds change point by point.
Factors affecting live odds:
-
Break of serve
-
Momentum swings
-
Medical timeouts
-
Crowd pressure
-
Tie-break situations
📌 Pro Tip: Live odds often overreact — great for experienced bettors.
