Baseball Slugging & OPS Calculator

In Major League Baseball (MLB), a league-average OPS is usually around .720 to .750. An OPS of .800 or higher is considered excellent, and an OPS of .900+ indicates an elite, MVP-caliber hitter.

Yes. The maximum possible slugging percentage is 4.000, which would happen if a player hit a home run in every single official At-Bat.

OPS stands for On-base Plus Slugging. It is a baseball statistic calculated by adding a player's On-Base Percentage (OBP) and Slugging Percentage (SLG). OPS provides a quick measure of a hitter's overall offensive production.

Slugging percentage (SLG) measures the power productivity of a batter. It is calculated by dividing total bases by at-bats. Unlike batting average, SLG weights extra-base hits more heavily.

On-base percentage (OBP) measures how frequently a batter reaches base safely. It is calculated as (H + BB + HBP) divided by (AB + BB + HBP + SF). OBP is considered more valuable than batting average for evaluating hitters.

Batting average (AVG) is calculated by dividing hits by at-bats. A .300 average is considered excellent in MLB. Batting average does not account for walks or extra-base hit value.

OPS = OBP + SLG. For example, if a player has a .350 OBP and .500 SLG, their OPS is .850. The formula combines on-base ability with power production into one number.

SLG = Total Bases / At Bats. Total Bases = Singles + (2 × Doubles) + (3 × Triples) + (4 × Home Runs). For example, 57 total bases in 100 at-bats gives a .570 SLG.

OBP = (Hits + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies). For example, (30 + 10 + 2) / (100 + 10 + 2) = .357 OBP.

In MLB, a league-average SLG is around .400-.420. A SLG of .500+ is above average, .600+ is excellent, and .700+ is elite. The maximum possible is 4.000.

In MLB, a league-average OBP is around .310-.320. An OBP of .370+ is above average, .400+ is excellent, and .450+ is elite among qualified hitters.

In MLB, a league-average batting average is around .250-.260. A .300+ average is considered excellent, and .350+ is elite. However, batting average alone does not fully measure offensive value.

Weighted On-Base Average (wOBA) is a more advanced metric that assigns different weights to each offensive event (singles, doubles, walks, etc.). It provides a more accurate picture of offensive production than OPS.

Weighted Runs Created Plus (wRC+) is an advanced metric that adjusts wOBA for ballpark and league effects. A wRC+ of 100 is league average; 150 means 50% better than average.

OPS+ adjusts OPS for ballpark and league effects. An OPS+ of 100 is league average. An OPS+ of 150 means the player produced 50% above league average after park adjustments.

Isolated Power (ISO) measures raw power by subtracting batting average from slugging percentage. ISO = SLG - AVG. An ISO of .200+ is above average; .300+ is elite power.

Total bases (TB) are the sum of all bases gained from hits: Singles × 1 + Doubles × 2 + Triples × 3 + Home Runs × 4. Total bases are used to calculate slugging percentage.

At-bats (AB) are plate appearances that do not result in a walk, hit by pitch, sacrifice fly, or catcher's interference. At-bats are the denominator in batting average and slugging percentage.

A walk (BB or base on balls) occurs when a pitcher throws four balls outside the strike zone. Walks count toward OBP but not toward batting average or slugging percentage.

A hit by pitch (HBP) occurs when a batter is struck by a pitch. HBPs count like walks for OBP purposes but do not count as at-bats or hits.

A sacrifice fly (SF) is a fly ball that allows a runner to score after tagging up. Sacrifice flies are excluded from at-bats but reduce OBP because they provide an extra plate appearance without a hit or walk.

A double is a hit that allows the batter to reach second base safely. Doubles are worth 2 total bases and are a key component of slugging percentage.

A triple is a hit that allows the batter to reach third base safely. Triples are worth 3 total bases and are relatively rare in modern baseball.

A home run is a hit that allows the batter to circle all bases and score. Home runs are worth 4 total bases and are the most impactful hit for slugging percentage.

A single is a hit that allows the batter to reach first base safely. Singles are worth 1 total base and are the most common type of hit.

Slugging percentage measures a batter's power productivity. It is used to evaluate hitting ability, compare players across eras, and is a key component of OPS and advanced metrics.

On-base percentage measures a player's ability to reach base. It is considered the most important offensive statistic because getting on base creates scoring opportunities.

OPS combines on-base ability and power into one number. It provides a quick overall measure of offensive production and is widely used for player comparisons and evaluations.

Enter at-bats, hits, walks, hit by pitch, sacrifice flies, and hit types (singles, doubles, triples, home runs). The calculator computes AVG, SLG, OBP, and OPS.

Enter hits and at-bats. Batting average = hits / at-bats. For example, 30 hits in 100 at-bats = .300 batting average.

Enter total bases and at-bats. SLG = total bases / at-bats. For example, 57 total bases in 100 at-bats = .570 SLG.

Enter hits, walks, hit by pitch, at-bats, and sacrifice flies. OBP = (H + BB + HBP) / (AB + BB + HBP + SF).

OPS = OBP + SLG. The calculator computes OBP and SLG from your inputs, then adds them together.

Enter singles, doubles, triples, and home runs. Total bases = (1B × 1) + (2B × 2) + (3B × 3) + (HR × 4).

OPS combines the two most important offensive skills: getting on base and hitting for power. It provides a more complete picture than batting average alone.

Slugging percentage values extra-base hits more than singles. It measures a player's ability to drive the ball for extra bases, which creates more runs.

OBP measures a player's ability to avoid making outs. In baseball, where outs are limited, getting on base is the most valuable offensive skill.

Batting average treats all hits equally and ignores walks. A .300 hitter who only hits singles may be less valuable than a .280 hitter with power and walks.

OPS includes both on-base ability (OBP) and power (SLG), giving a more complete picture of offensive production than batting average alone.

OPS weights OBP and SLG equally, but OBP is actually more valuable. Advanced metrics like wOBA and wRC+ provide more accurate offensive evaluations.

Calculating stats helps evaluate player performance, compare players, make lineup decisions, and understand offensive contribution.

Teams value OBP because getting on base creates scoring opportunities. OBP is strongly correlated with run production and winning games.

Power hitting (SLG) drives in runs and creates extra-base opportunities. Teams value players who can hit for extra bases consistently.

OPS adds OBP and SLG. wOBA assigns different weights to each offensive event, providing a more accurate measure of offensive production.

OBP includes walks and hit by pitch; batting average only includes hits. OBP is a better measure of a player's ability to reach base.

SLG weights extra-base hits more heavily; batting average treats all hits equally. SLG measures power while batting average measures contact.

OPS is raw OBP + SLG. OPS+ adjusts for ballpark and league effects, making it better for comparing players across different environments.

ISO = SLG - AVG. ISO measures raw power by removing the contribution of singles. SLG includes all hits weighted by bases.

Hits count each hit equally. Total bases weight hits by type: singles = 1, doubles = 2, triples = 3, home runs = 4.

At-bats (AB) exclude walks, HBP, and sacrifices. Plate appearances (PA) include all trips to the plate. PA is used for OBP; AB is used for AVG and SLG.

Runs Created estimates total runs contributed. OPS measures on-base and power. Runs Created is more comprehensive but harder to calculate.

Both are park and league adjusted. wRC+ uses wOBA; OPS+ uses OPS. wRC+ is considered more accurate for measuring offensive production.

AVG only counts hits. OBP counts hits, walks, and HBP. OBP better reflects a player's ability to get on base and avoid outs.

Use when evaluating player performance, comparing hitters, constructing lineups, or analyzing offensive statistics.

OPS is most useful for quick player comparisons and evaluating overall offensive contribution. It is widely available in box scores and statistics pages.

SLG is most useful when evaluating power hitters and comparing extra-base hit production between players.

OBP is most useful when evaluating table-setters and leadoff hitters who need to get on base frequently.
