2-way arbitrage calculator
How this calculator works
Arbitražas lažybos (also called "arbing") exploits price differences across bookmakers to guarantee a profit regardless of outcome. For a 2-way rinka, a risk-free situation exists when the sum of the inverse of each koeficientai is less than 1.00.
The arb percentage formula is: arb% = (1/koeficientai1 + 1/koeficientai2). If this sum is below 1.00, an arbitrage opportunity exists. The lower the arb%, the larger the guaranteed profit margin.
Stake allocation for Outcome 1 uses: stake1 = iš viso x (1/koeficientai1) / arb%. Outcome 2 receives the remainder. This ensures both outcomes return the same iš viso payout.
For example, with Outcome 1 at 2.10 and Outcome 2 at 2.05, the arb% = (1/2.10 + 1/2.05) = 0.4762 + 0.4878 = 0.9640. Since this is below 1.00, an arb exists. On a iš viso stake of 100, the guaranteed profit is 100 / 0.9640 - 100 = 3.73 units.
Stake allocation is proportional to the implied probability of each outcome. The higher-koeficientai outcome receives a smaller stake; the lower-koeficientai outcome receives a larger stake. Both produce identical returns on a win.
In practice, real-time pricing and sąskaita restrictions make arbing difficult at most bookmakers. This calculator is intended primarily for understanding the math and for quick checks on promotional rinkas where koeficientai may be inflated.
The calculator assumes no commission is charged. Lay bets (at exchanges) carry commission which reduces guaranteed profit. Use the Matched Bet calculator for commission-adjusted lay calculations.

DUK
What arb percentage is profitable?
Any arb% below 100% (expressed as a decimal below 1.00) is profitable. Lower percentages yield higher guaranteed profit. Anything above 1.00 means no arb exists.
Do bookmakers allow arbitrage lažybos?
Most bookmakers restrict or limit sąskaitas identified as arbers. Arbing is legal but can lead to stake restrictions or sąskaita closures. Always check sąlygos.
Can this work for 3-way rinkas?
Yes, the principle extends to 3 outcomes: arb% = (1/o1 + 1/o2 + 1/o3). The surebet calculator on this site handles 3-way rinkas explicitly.
Why must I split stakes proportionally?
Proportional stakes ensure equal return regardless of outcome. Unequal stakes would mean one outcome returns more than another, creating exposure to loss.
What is the difference between arbitrage and a surebet?
They are the same concept. "Arbitražas" is the financial term; "surebet" is the sporto lažybos community term. Both refer to guaranteed profit from koeficientai discrepancies.
