What is Arbitrage Calculator?
An arbitrage calculator is a tool that helps identify and calculate arbitrage opportunities in sports betting. Arbitrage betting involves placing bets on all possible outcomes of an event with different bookmakers to guarantee a profit regardless of the result.
The calculator takes the odds offered by different bookmakers as input and determines the optimal stake for each bet to maximize profit. It calculates the potential profit and return on investment (ROI) for the arbitrage opportunity.
How to Use the Arbitrage Calculator
1. Enter the odds for each bet in the corresponding input fields. You can add up to 6 bets using the "Add Bet" button.
2. Enter the total stake amount you wish to wager.
3. Click the "Calculate Arbitrage" button to see the recommended stake for each bet, the potential payout, total profit, and ROI.
4. Place your bets with the recommended stake amounts on the corresponding betting platforms.
By using the arbitrage calculator, you can identify profitable betting opportunities and optimize your stakes to maximize your returns.
Example
Let's say you find the following odds for an NFL game:
- Bookmaker A: Team 1 wins at +150 odds
- Bookmaker B: Team 2 wins at -120 odds
You enter these American odds into the arbitrage calculator with a total stake of $100. The calculator determines that by placing a stake of $42.31 on Team 1 at Bookmaker A and $57.69 on Team 2 at Bookmaker B, you can guarantee a profit of $5.77 regardless of the outcome, resulting in an ROI of 5.77%.
Frequently asked questions
What is an arbitrage bet?
An arbitrage exists when two sportsbooks price opposite sides of the same market such that the combined implied probability is under 100%. Backing both sides in the right proportions locks in a profit regardless of the result.
How is the stake split calculated?
Each side is staked in proportion to the inverse of its decimal odds, so both outcomes return the same total payout. The calculator does this division for you and shows the guaranteed return on the combined outlay.
Why do arbitrage opportunities disappear so quickly?
Books move lines toward each other as sharp money arrives, and the mispriced side is usually the stale one. Most arbs survive minutes at best, which is why arbers automate their price feeds.
What are the practical risks?
The main ones are a line moving after you place the first leg, a book voiding one side under different settlement rules, and account limits for accounts that only bet arbs. Always confirm both prices are still live before placing the second leg.
