Arbitrage Betting Calculator

Arbitrage betting is a strategy where a bettor bets on all possible outcomes of a sports event at different bookmakers. In perspective, they can get guaranteed profit regardless of the result. But for the strategy to work, precise calculation is needed. You can make it using the arbitrage betting calculator from our website — it's free and doesn't require registration.

How does the arbitrage betting calculator work?

The arbitrage betting calculator helps the bettor accurately calculate what amount should be bet on each outcome of the event. It is based on odds for all possible results of the event. Manual calculation of an arbitrage bet requires calculating stake shares for each outcome, however the calculator automates this process.

EXAMPLE

Let's say you found an arbitrage situation in a tennis match. One bookmaker offers odds of 2.10 for player A's victory, and another — 2.15 for player B's victory. Since a draw is impossible, arbitrage is possible if the sum of inverse odds is less than 1:

• 1 / 2.10 ≈ 0.4762
• 1 / 2.15 ≈ 0.4651
• Sum: 0.9413 (less than 1)

You want to bet a total of $100. The arbitrage betting calculator will show:

• Bet on player A: $100 × 0.506 ≈ $50.60
• Bet on player B: $100 × 0.494 ≈ $49.40

Possible result:

• Player A wins: $50.60 × 2.10 = $106.26
• Player B wins: $49.40 × 2.15 = $106.21

Guaranteed profit: approximately $6.20, regardless of who wins.
