NHL playoffs: format and series odds
Enter the chance that a team wins one playoff game. The calculator below turns it into the chance to win a best-of-seven series, by series length.
Team A wins about 51 series in 100. With home ice going to Team B instead it would be 49.3% – home ice is worth 1.4 points here. The series goes the full 7 games 31.3% of the time.

How it is calculated
Each game is independent: Team A wins at home with the first chance and on the road with the second. Overtime in the playoffs goes on until a goal, so every game has a winner.
We follow every score from 0–0 to 4 wins, game by game, in the 2-2-1-1-1 order: chance of a score = chance of the score before × chance of the next game’s result.

Series chance from one game
P(series) = chance to win four games before the opponent wins four, summed over every possible series length
Example: A team that wins 55% of games wins the series 60.8% of the time and sweeps 9.2% of the time.
One game vs a whole series
| Matchup | Chance to win one game | Chance to win the series |
|---|---|---|
| Even teams | Coin flip | 50% |
| Small edge | 55% | 60.8% |
| Clear edge | 60% | 71.0% |
Small edges per game grow over a series. The more games are played, the more often the stronger team comes out ahead.
