Built for the 2026 NFL Season
The 2026 NFL regular season runs 18 weeks from September 10, 2026 into early January 2027, followed by the 14-team playoffs. Our playoff predictor is built around that exact format: four division winners plus three wildcards per conference, seeds 1–7, one bye per side. Make your picks before Week 1 and the tool pulls the real standings — refreshed nightly — to score your prediction all season long.
Settle the quarterback arguments too
When the group chat starts arguing about whose quarterback had the better game, the passer rating calculator settles it with the league's official formula — enter completions, attempts, yards, touchdowns and interceptions from any box score and get the 0–158.3 rating instantly, with the four component scores shown so you can see exactly what dragged a rating down. A toggle switches to the NCAA passing efficiency formula for college games.
More before kickoff
This hub is new and growing — more NFL tools are planned before the season starts. If you also follow the European game, the same predict-then-track format powers our Premier League table predictor and its Bundesliga, La Liga and Serie A siblings.
