Quick Facts

- Inputs: odds (any format) & total stake.
- Outputs: stake per outcome, payout, profit margin.

How to use
Steps
Enter odds for each outcome and your total stake. The tool allocates stakes to equalise payout and flags if a true arbitrage opportunity exists.
Use it as a 3 way arbitrage calculator for soccer and other multi-outcome markets. Many bettors call it an arb tool, but it works for any sports betting arbitrage calculator use case.
Example (2‑way)
Odds: 2.10 and 1.95 with a total stake of R1,000. The calculator splits your stake so each outcome returns the same payout and highlights whether the implied probabilities sum below 100%. If they do, you have a true arbitrage opportunity.
Practical tips
- Always check that odds are still live before staking.
- Factor in limits and bet delays on each sportsbook.
- Prefer higher liquidity markets for faster fills.
