About this calculator

This arbitrage calculator splits stakes across the entered outcomes and shows the modelled payout and ROI. Confirm that the markets match and every bet is accepted at the entered price.

This free arbitrage calculator is a betting arbitrage calculator that shows how much to stake on each entered outcome for an even modelled return. You can use it for normal 2-way markets (Team A vs Team B), 3-way markets, or even big events like the Super Bowl where every bookmaker has slightly different prices. Just enter your odds, enter your total stake, and the tool shows you the exact amounts to place plus total payout and ROI.

  1. Enter the Odds:
    Input the odds for two or more bets from different bookmakers in the respective fields. Make sure the odds are accurate to avoid calculation errors.
  2. Enter Your Total Stake:
    Specify the total amount you want to bet. This helps the calculator determine the precise stakes for each bookmaker.
  3. Calculate:
    Click the 'Calculate' button to let the tool determine the optimal stake for each bet. The tool will instantly display the required stakes to calculate the modelled return.
  4. Analyze Results:
    Review the results. A positive ROI indicates a positive modelled ROI, while a negative ROI suggests a loss. Recheck the market, odds and stakes accordingly for the best outcome.

Arbitrage betting, also known as "arb betting" or "surebets," calculates whether all listed outcomes can be covered across different bookmakers for less than the total return. Moving prices, rejected bets, limits and market mismatches remain practical risks.

Arbitrage bets exist due to the following reasons:

  • Bookmaker Mistakes: Occasionally, bookmakers set odds incorrectly, creating discrepancies that can be exploited.
  • Market Differences: Bookmakers may have different opinions or access to different data when setting their odds.
  • Slow Updates: Some bookmakers are slower to adjust their odds in response to market changes, leaving opportunities for savvy bettors.

Let’s say you find the following odds:

  • Bookmaker A: Team X to win at 2.10
  • Bookmaker B: Team Y to win at 2.10

You want to invest $100 total. The arbitrage calculator will tell you how much to stake on each outcome for an even calculated return. In this case:

  • Stake $50 on Bookmaker A
  • Stake $50 on Bookmaker B

No matter which team wins, your total payout is $105, resulting in 5% ROI. You can easily find these opprounties using the arbitrage Calculator.

While it is possible to manually identify arbitrage opportunities, it can be time-consuming and complex due to the need to compare odds across multiple bookmakers. At WagerWise, we simplify this process with our advanced Arbitrage Betting Tool, designed to:

  • Scan odds across a wide range of bookmakers in real-time.
