What is WAR?
Wins Above Replacement (WAR) is a sabermetric designed to summarize a baseball player’s overall contribution to their team’s performance. It’s a useful metric to quickly assess a player’s value, helping teams make decisions on who should play to increase their chances of winning.
Strengths and Weaknesses of WAR
WAR is not standardized, and various sources offer slightly different formulas. Our calculator is based on the FanGraphs sabermetric, known for its reliability in baseball statistics. While not perfect, WAR provides a unique perspective on a player’s value.
How to Use the WAR Calculator
- Choose Player Type: Decide if you’re calculating WAR for a position player or a pitcher.
- Input Data: Enter relevant statistics based on player type, such as batting runs, base running hits, or league FIP.
- Get Results: Let the calculator process the information to provide the WAR value.
WAR Calculation Equations
- Position Players: WAR=(RunsPerWin)(BattingRuns+BaseRunningRuns+FieldingRuns+PositionalAdjustment+LeagueAdjustment+ReplacementRuns)
- Pitchers: WAR=9((League“FIP”–“FIP”)/(PitcherSpecificRunsPerWin+ReplacementLevel))×(InningsPitched)×(LeverageMultiplierforRelievers)+LeagueCorrection
For detailed component calculations, refer to FanGraphs’ sections on WAR for position players and pitchers.
Interpreting WAR Results
- 0 – 1 WAR: Scrub
- 1 – 2 WAR: Role Player
- 2 – 3 WAR: Solid Player
- 3 – 4 WAR: Good Player
- 4 – 5 WAR: All-Star

Keep in mind that WAR isn’t precise but helps group players by skill level.
