Check whether decimal odds across mutually exclusive outcomes form an arbitrage and allocate a bankroll for equal gross returns.

About the Surebet Calculator
Check whether decimal odds across mutually exclusive outcomes form an arbitrage and allocate a bankroll for equal gross returns.
How the Surebet Calculator Works
Inverse decimal odds are summed, bankroll is divided in proportion to each inverse odd, and equalized return and guaranteed profit are reported only when the sum is below one.
Formula
Implied sum = sum(1/odds_i); stake_i = bankroll*(1/odds_i)/implied sum; arbitrage exists when implied sum < 1.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
