Calculate BA, OBP, SLG and more baseball statistics
This baseball batting statistics calculator computes the most important offensive metrics used to evaluate player performance. Enter your at-bats, hits, and hit types to instantly calculate batting average (BA), on-base percentage (OBP), slugging percentage (SLG), and OPS.
Perfect for players tracking their season stats, coaches evaluating performance, fantasy baseball managers, or fans analyzing their favorite players.
Batting average measures how often a batter gets a hit. It's the most traditional batting statistic.
A .300 batting average (getting a hit 30% of the time) is considered excellent. The MLB league average typically hovers around .250-.260.
On-base percentage measures how frequently a batter reaches base by any means (hits, walks, or hit by pitch).
OBP is often considered more valuable than batting average because it accounts for walks. A .400 OBP is excellent.
Slugging percentage measures the power of a hitter by calculating total bases per at-bat.
Total Bases = (1B × 1) + (2B × 2) + (3B × 3) + (HR × 4)
A .500 slugging percentage is considered very good, with elite power hitters reaching .600+.
OPS combines on-base percentage and slugging percentage into a single metric. It's one of the best quick measures of overall offensive value.
OPS benchmarks: .800+ is good, .900+ is excellent, 1.000+ is elite.
ISO measures a player's raw power by showing their extra-base hit ability.
An ISO of .200+ indicates strong power hitting.
Here's how batting statistics are typically evaluated at different competitive levels:
Standards vary significantly by age group and competition level. A .400 batting average in youth baseball might be good but not exceptional, while the same average in competitive high school ball would be outstanding.
Top college hitters typically produce batting lines around .330 BA / .420 OBP / .550 SLG, though this varies by conference strength.
Make sure your total hits equals the sum of singles, doubles, triples, and home runs. The calculator uses your total hits value for BA, so hit types must add up correctly.
No. Walks (bases on balls) do not count as official at-bats. They do count toward on-base percentage and plate appearances.
Batting average only counts hits divided by at-bats. OBP includes walks and hit-by-pitch, and uses plate appearances (which include walks, HBP, and sacrifice flies) as the denominator. OBP gives a more complete picture of how often a player reaches base.
In Major League Baseball, an OPS of .800 is considered good, .900 is excellent, and 1.000+ is elite. The league average is typically around .720-.750.
Keep a running total of all counting stats (at-bats, hits, walks, etc.) after each game. Simply add new numbers to your season totals and recalculate. This calculator works for single games, seasons, or careers.
No. Sacrifice flies do not count as at-bats, but they do reduce your on-base percentage because they count as a plate appearance without reaching base.
If you don't know hit types, you can still calculate batting average and on-base percentage. For slugging percentage, you'll need to know at least how many extra-base hits occurred. Without hit type breakdown, assume all hits are singles for a conservative SLG estimate.
Yes! The formulas for batting average, OBP, SLG, and OPS are identical in baseball and softball. Simply enter your softball statistics to calculate your hitting metrics.
