A complete set of simple, accurate calculators for pitching and hitting stats — built for players, coaches, and parents who want fast answers without the math.
Calculate a pitcher's Earned Run Average for a single game or a full season. Supports 9, 7, and 6-inning formats for MLB, softball, college, high school, and youth ball, with a quality rating for every result.
Work the ERA math backwards. Find how many innings a pitcher needs, what ERA they must post, or how many earned runs they can allow to hit a target — perfect for chasing a season goal or a Cy Young pace.
Walks and hits per inning pitched — the stat coaches read alongside ERA to see how many base runners a pitcher really allows. Single-game or full-season, with a quality rating.
Fielding Independent Pitching strips out defense and luck to measure what a pitcher actually controls — home runs, walks, and strikeouts — on the ERA scale. Includes an editable FIP constant.
For youth baseball: enter a pitcher's age and pitches thrown to get the required rest days and next eligible date, plus a live in-game pitch counter. Based on Little League and PitchSmart rules.
Turn hits and at-bats into a clean batting average, for a single stretch or a full season, with benchmarks for what counts as good at each level.
On-base plus slugging in one number. Enter a hitter's line to get OBP, SLG, and OPS together — the quick modern measure of a hitter's total offensive value.
Baseball and softball stats look simple, but the math trips people up — partial innings, different game lengths, earned versus unearned runs, and which plate appearances count as at-bats all change the result. These tools handle the details for you so the number is right the first time.
Every tool here is free, works on your phone, and is built around the same goal: give you an accurate answer in seconds, then explain what it means. Start with the ERA Calculator if you're tracking pitching, or the batting average calculator for hitting. For benchmark guides on what counts as a good ERA at every level — from youth ball to college recruiting and softball — check the blog.
From quick everyday stats like ERA and batting average to advanced measures like FIP and OPS, plus a youth pitch-count safety tool, this is a complete set of calculators for players, coaches, and parents at every level of the game.
