Type two NBA team names into the boxes below (start typing and pick from the suggestions), choose which one is the home team, and press Calculate true odds.

You'll get each team's estimated chance of winning, the "fair" decimal odds and moneyline that chance implies, and their past head-to-head results.

If you've got odds from a sportsbook for the same game, pop them into the two boxes at the bottom of the results to see whether the price looks generous or stingy compared to this model.

The leaderboard further down shows current Elo ratings for all 30 teams, based on results through .

The button above fetches the current season's schedule directly from the sportsdataverse-data GitHub release and merges it in — one click, no download step. It needs an internet connection and can fail if the season file isn't published yet or your network blocks GitHub; if so, use the manual option below. Download a season's schedule CSV from github.com/sportsdataverse/sportsdataverse-data (release tag espn_nba_schedules, file named like nba_schedule_2027.csv) and drop it in here. This is a standard header-row CSV; the columns used are date, season_type, status_type_completed, home_abbreviation, home_score, away_abbreviation, away_score. New completed regular-season, play-in and playoff games merge in and duplicates are skipped automatically — ratings recalculate instantly in your browser. Nothing is uploaded anywhere; it's all processed locally on this page. Once you've merged new data, use your browser's Save Page As (Ctrl/Cmd+S) and choose "Webpage, HTML only" to save it as a new file with the update baked in — otherwise it's only good for this browser session and reverts to the built-in data on reopen.
