Free sports betting calculators. Check the math first.
Calculate no-vig probabilities, Kelly stakes, arbitrage splits, order-book edge, and sharp-consensus fair value without signing up. These tools are for education and spot checks; outputs depend on the inputs and do not guarantee a profitable bet.
Enter prices from sharp books and exchanges to estimate a fair probability. This is the manual version of the consensus layer CLV.gg uses before it flags +EV, arbs, middles, low holds, and steam.
Compare a fair probability against a sportsbook or exchange price, then adjust for fees. Useful for checking whether a displayed price is still worth betting after costs.
Convert fair odds, offered odds, bankroll, and Kelly fraction into a stake size. Shows full Kelly, fractional Kelly, recommended stake, and edge.
Remove market vig from two-, three-, or four-outcome prices. Compare power, multiplicative, and additive no-vig probabilities side by side.
Check whether the best prices across every outcome create an arb, then calculate the stake split, payout balance, and arb percentage.
