Calculate arbitrage stake sizing, middle P/L, expected value, and no-vig fair lines. Same math we use in our live arb, middles, and +EV feeds. Free, no signup.
Every tool takes American odds and runs the calculation instantly. Use them to size a bet before you place it, sanity-check a price, or strip out the vig to find a fair line. The tools handle the math. Our live feeds find the bets across 20+ sportsbooks, exchanges, and prediction markets in real time.
Size stakes across two or three legs so payout matches. See guaranteed profit or when there is no arb.
Size both legs from leg 1 stake. See P/L if one side wins, profit if the middle hits, and the hold rate.
Compare offered odds to your fair line. Edge as EV% plus full and half Kelly stake.
Power-method no-vig fair prices for each side of a market. Same method as our feeds.
