List of all-time NFL win–loss records

The National Football League (NFL) is a professional American football league, which as of the end of its 2024 season, consists of 32 teams. These teams are divided equally between the National Football Conference (NFC) and the American Football Conference (AFC), and both conferences contain four divisions with four teams each. Since its formation in 1920, as the American Professional Football Association (APFA), NFL game results have been recorded. Games in the NFL can either end with a winner and a loser, or the two teams can tie. The NFL officially counts ties in its standings; ties are registered as a half-win and a half-loss when calculating the win–loss percentage. However, this method of assessing ties in the win–loss percentage has only been in place since the 1972 season, meaning all ties prior do not affect a team's win percentage. One of only two charter members of the NFL still in existence, the Chicago Bears, have played the most games (1,486) and recorded the most ties (42) in NFL regular season history. Their NFC North divisional rivals, the Green Bay Packers have recorded the most wins (811) in NFL history. The league's other still-active charter member, the Arizona Cardinals, have recorded the most regular season losses (812), through the end of the 2024 season. The Baltimore Ravens hold the highest regular season win–loss percentage (.574), with a 268–199–1 record through the end of the 2024 season. The Tampa Bay Buccaneers maintain the lowest regular season win–loss percentage (.410), holding a 318–457–1 record through 2024. Being the most-recently founded franchise in the NFL, the Houston Texans have recorded the fewest regular season games played (338) and wins (142). The Ravens have recorded the fewest regular season losses (199). Through the end of the 2024 regular season, the Jacksonville Jaguars are the only team that has not yet recorded a tie. Following the regular season, teams that won their respective divisions, in addition to three wild card teams determined by a conference's next best three teams—regardless of division—qualify for the league's postseason, called the playoffs. Ties cannot occur in the playoffs. The Cowboys have played in the most playoff games (67), through the end of 2023–24 NFL Conference Championship games. The Patriots have the highest playoff win–loss percentage (.627), with a 37–22 record, as of the end of the same round. The San Francisco 49ers have the most post-season victories (39) in NFL playoff history, while the Minnesota Vikings have the most playoff losses (32). The Detroit Lions and Los Angeles Chargers both share the lowest playoff win–loss percentage of all-time, respectively holding records of 9–15 (.375) and 12–20 (.375). The Houston Texans have the fewest games played (12), wins (5), and losses (7) in NFL playoff history. The NFL officially counts and includes the statistical records logged by teams that played in the American Football League (AFL) and All-America Football Conference (AAFC). AFL statistics were incorporated upon the AFL–NFL merger in 1970; meanwhile, though the AAFC merged into the NFL in 1950, the NFL did not begin incorporating AAFC statistics and history into its own record books until April 1, 2025.
