Free calculators for sports betting and fantasy leagues. Runs entirely in your browser — no account, no data sent anywhere.
The parlay calculator handles all major odds formats used globally — American moneylines used in the US, decimal odds used in Europe and Australia, fractional odds common in the UK, and implied probability which converts any format into the bookmaker's implied win percentage. Parlays combine multiple bets where all legs must win: the combined decimal odds equal the product of each leg's decimal odds, giving exponentially larger payouts but lower probability.
The fantasy points calculator covers three major sports leagues. NFL scoring varies significantly by format — full PPR leagues reward pass-catching running backs and slot receivers far more than standard formats. IPL Dream11 scoring rewards all-rounders who contribute across batting, bowling, and fielding, with significant bonus points for milestones (50-run half-centuries, 5-wicket hauls) and performance bonuses based on strike rate and economy rate.
