1. What is 3-Way Arbitrage?

3-way arbitrage in betting occurs when the sum of the reciprocals of the odds for all three outcomes is less than 1, indicating a guaranteed profit regardless of the outcome. This represents a mathematical advantage for the bettor.

2. How Does the Calculator Work?

The calculator uses the arbitrage formula:

Where:

• \( O1 \) — Odds for outcome 1 (decimal format)
• \( O2 \) — Odds for outcome 2 (decimal format)
• \( O3 \) — Odds for outcome 3 (decimal format)

Interpretation: If Arb < 1, an arbitrage opportunity exists. The lower the value, the greater the potential profit.

3. Importance of Arbitrage Calculation

Details: Arbitrage betting allows bettors to guarantee profits by placing bets on all possible outcomes across different bookmakers. It requires precise calculation and quick execution.

4. Using the Calculator

Tips: Enter decimal odds for all three outcomes from different bookmakers. All values must be greater than 0. The calculator will determine if an arbitrage opportunity exists.

5. Frequently Asked Questions (FAQ)

Q1: What does Arb < 1 mean?
A: When the sum of the reciprocals of the odds is less than 1, it indicates that you can place bets on all outcomes and guarantee a profit.

Q2: How do I calculate stake amounts for each outcome?
A: To calculate individual stakes, divide the reciprocal of each odd by the total arbitrage value, then multiply by your total investment.

Q3: Are arbitrage opportunities common?
A: True arbitrage opportunities are rare and typically short-lived as bookmakers quickly adjust odds to eliminate them.

Q4: What are the risks of arbitrage betting?
A: Risks include odds changing before all bets are placed, account restrictions from bookmakers, and human error in calculations.

Q5: Can I use this for sports betting?
A: Yes, this calculator is specifically designed for 3-outcome sporting events like soccer (win/draw/lose) or tennis sets.
