What this does: Enter the two American prices from different books and your total stake. This calculator tells you whether an arbitrage exists, how to split your stake, and the guaranteed profit.

Key takeaways

  • Arbitrage exists when the two prices imply under 100% combined.
  • The calculator splits your stake so every outcome pays the same.
  • Reduced-juice books make arbs easier to find and larger.

How it works

Each price converts to decimal odds; the reciprocal of each is its implied probability. If the two implied probabilities sum to under 100%, you can stake both sides so any outcome returns the same amount — a guaranteed profit. The calculator splits the stake proportionally.

Why this matters

Arbitrage relies on price differences and low margins. Bet105 allows arbitrage with no penalty and prices reduced juice. See arbitrage and does Bet105 allow arbitrage.

FAQ

What is arbitrage betting?

Betting all outcomes of an event across different prices so the total staked returns a guaranteed profit regardless of result.

Will Bet105 limit me for arbitrage?

No. Bet105 allows arbitrage with no account penalty.

Why do reduced-juice books help?

Lower margins make the combined implied probability more likely to fall under 100%, which is what creates an arb.
