Arbitrage betting since 2011
Free surebet calculator for arbitrage bettors
Surebet Monitor started in 2011 as a surebet scanner written by bettors for bettors. Today it is a free calculator that splits your stakes across two or three bets so every result pays the same, with stake tax, Asian lines and a catalog of nearly 20,000 ready-made combinations.
What the calculator does
Two or three bets
Match result, double chance, totals, handicaps and more: pick the bets that cover every result and the calculator finds the stakes.
Stake tax and tax-free bets
Set a stake tax such as Poland's 12%, mark the bets that are tax-free and see what every scenario really pays.
Nearly 20,000 combinations
Not sure which bets cover every result? Search the catalog of ready-made combinations or build one bet by bet.
A surebet in numbers
Two bookmakers disagree about one match: one pays 2.10 on over 2.5 goals, the other 2.05 on under 2.5 goals. 1/2.10 + 1/2.05 = 0.964, below 1, so the prices leave room for a profit.
| Bet | Stake | Returns |
|---|---|---|
| Over 2.5 goals at 2.10 | 49.40 | 103.74 |
| Under 2.5 goals at 2.05 | 50.60 | 103.73 |
| Total | 100.00 | a profit of 3.73 (3.7%) whatever the score |
Without stake tax. Prices move within minutes, and a surebet only exists while both of them do: place both bets before either one changes.
