Baseball Calculators

Calculate FIP — a pitching metric that removes fielding from evaluation. Enter K, BB, HBP, HR, and IP — get FIP with ERA comparison. Free.

Calculate xFIP (Expected Fielding Independent Pitching) using league-average HR/FB rate. Enter pitching stats — get xFIP for predictive pitcher evaluation. Free.

Estimate Wins Above Replacement for a hitter or pitcher. Enter key performance stats — get approximate WAR with positional adjustment. Free.

Calculate Batting Average on Balls In Play. Enter hits, HR, AB, K, and SF — get BABIP with luck indicator and expected regression. Free.

Analyze batted ball quality from launch angle and exit velocity. Enter both values — get expected hit type, xBA, and slugging probability. Free.

Calculate ERA+ — park and league-adjusted ERA. Enter ERA, league ERA, and park factor — get ERA+ with historical context. Free.

Calculate On-base Plus Slugging. Enter on-base percentage and slugging percentage — get OPS with performance tier classification. Free.

Calculate slugging percentage from raw batting stats. Enter singles, doubles, triples, HR, and AB — get SLG with league-average comparison. Free.

Calculate OBP from plate appearance data. Enter hits, walks, HBP, AB, and SF — get on-base percentage with league-average comparison. Free.

Calculate Walks plus Hits per Inning Pitched. Enter walks, hits, and innings pitched — get WHIP with performance rating and ERA correlation. Free.

Calculate pitcher strikeout rate (K%). Enter strikeouts and batters faced — get K% with swing-and-miss context and percentile ranking. Free.

Calculate pitcher walk rate (BB%). Enter walks and batters faced — get BB% with command rating and control percentile context. Free.

Calculate stolen base success rate and break-even point. Enter stolen bases and caught stealing — get success rate with break-even threshold. Free.

Calculate pitcher efficiency: pitches per inning, per batter, and quick outs. Enter pitching data — get efficiency score and deep game probability. Free.

Calculate barrel rate from batted ball data. Enter barrels and batted ball events — get barrel% with xSLG and hard-hit rate context. Free.

Calculate hard-hit rate (balls hit 95+ mph exit velocity). Enter hard-hit events and total batted balls — get hard-hit% with xBA and xSLG. Free.

Calculate batter or pitcher chase rate on pitches outside the strike zone. Enter chases and out-of-zone pitches — get chase% with discipline score. Free.

Calculate batter contact rate (Z-Contact%, O-Contact%, overall). Enter swings and contacts — get contact rates with plate discipline breakdown. Free.

Calculate ground ball%, fly ball%, and line drive% for pitchers or hitters. Enter batted ball totals — get GB/FB/LD breakdown with park-factor context. Free.

Calculate baseball sprint speed and base-running value. Enter 90-foot split times or Statcast feet-per-second — get sprint speed grade and positional context. Free.
