SharpOddsIQ

SharpOddsIQ is a free set of eight sports betting calculators built to work together. Calculate parlay payouts, convert odds between American, decimal and fractional formats, find hedge amounts, size bets with the Kelly Criterion, check expected value, spot arbitrage, and remove the vig to find fair odds. Every tool accepts any odds format and includes a worked example. The standout feature is a built-in bet slip: save calculations from any tool to one place that tracks your stake, payout, and running profit and loss across your whole session. No sign-up, no cost.
