Arbitrage calculator

How much do I stake on each side?

+110 at one book and +105 at another is a 3.73% arbitrage on 1,000 staked:

Exact stakes493.98 / 506.02
Guaranteed37.35
Round stakes490 / 500
Guaranteed35.00
Cost of looking human2.35

A stake to the cent is the loudest fingerprint a risk desk reads. This solves for round stakes directly, because rounding a lock afterwards breaks it.

Where the number comes from

Everything above was computed by the same engine that prices bets, at the moment this page was built — not typed into a template. The build fails if a figure appears here and not in the engine's own output.
