Point Spread Calculator
All calculatorsThis calculator converts between a favorite win probability and a point spread, using a typical margin spread for each sport. It also shows the fair moneyline on both sides of the game.
What it does. It converts between a win probability and an estimated point spread, using a normal model tuned to each sport's usual margin of victory.
How to use it. Pick the sport, then enter a win probability to get the spread, or a spread to get the win probability. Change either box and the other updates.
Why it matters. It puts a moneyline and a spread on the same scale, so you can see which side of a game the market is pricing more generously. Treat it as an estimate, since real margins swing game to game.
Rough margin models: NFL 13.5, CFB 16, NBA 12, CBB 11, NHL 6.5, MLB 4.2 points of standard deviation. Estimates only.
