OPS (On-Base Plus Slugging) Calculator

OPS (On-base Plus Slugging) is a statistic in baseball that allows us to analyze how well a player is playing for his team. There are three key elements used to measure a player's overall offensive effectiveness, which are these:

• OPS (On-base Plus Slugging) - This is a combination of OBP and SLG in a single number that provides a clear view of how well a player gets on-base and hits with power.
• OBP (On-base Percentage) - It tells us how often a player reaches base by hits, walks, and being hit by a pitch.
• SLG (Slugging Percentage) - This evaluates a player’s power by measuring how many total bases he earns from singles, doubles, triples, and home runs.

What is OPS (On-base Plus Slugging) — Formula with Example?

OPS is a key stat in baseball that combines OBP and SLG. We have already explained that it provides a complete picture of a player's offensive ability. Let's see the formula for OPS:

OPS = OBP + SLG

Here is the complete formula for calculating OPS:

Calculate OBP (On-Base Percentage):

• OBP = (Hits + Walks + Hit by Pitch) / (At Bats + Walks + Hit by Pitch + Sacrifice Flies)

Calculate SLG (Slugging Percentage):

• SLG = (Singles + (2 x Doubles) + (3 x Triples) + (4 x Home Runs)) / At Bats

Calculate OPS:

• OPS = OBP + SLG

Real-world example

Let's see an example with the player's stats:

• At Bats (AB): 500
• Hits (H): 150
• Doubles (2B): 35
• Triples (3B): 5
• Home Runs (HR): 20
• Walks (BB): 60
• Hit by Pitch (HBP): 5
• Sacrifice Flies (SF): 5

Step 1: Using formula to calculate OBP

• OBP = (150 + 60 + 5) / (500 + 60 + 5 + 5)
• OBP = 0.377

Step 2: Using SLG formula:

First, calculate singles:

• Singles = Hits – Doubles – Triples – Home Runs
• Singles = 150 – 35 – 5 – 20 = 90

Now implement the formula:

• SLG = (90 + (2 x 35) + (3 x 5) + (4 x 20)) / 500
• SLG = 0.510

Step 3: Apply the formula to calculate OPS

• OPS = 0.377 + 0.510 = 0.887

We calculated the player's OPS as 0.887, indicating excellent offensive skill and performance.

Why OPS Matters

OPS is considered a key performance measure of a player in baseball. It provides a complete picture of the hitter's skills and resolves queries such as:

• What is the performance of the hitter?
• Does the player get on base consistently?
• Does the player hit for power?

OPS is an easy measurement that helps analysts, coaches, and fans compare players’ performance.

What is OBP (On-Base Percentage)?

OBP stands for On-Base Percentage. In baseball, it is a statistic that shows how often a player successfully reaches base. It takes into account:

• Hits (H)
• Walks (BB)
• Hit-by-pitch (HBP)

OBP is considered one of the most accurate indicators of offensive consistency because it includes walks and hit-by-pitches. A higher OBP indicates that the player is performing well and creating scoring opportunities.

Are you wondering what the equation looks like? Here’s the OBP formula:

OBP = (H + BB + HBP) / (AB + BB + HBP + SF)

Where:

• H = Hits
• BB = Walks
• HBP = Hit by pitch
• AB = At bats
• SF = Sacrifice flies

What Is a Good OBP in Baseball?

Let’s consider these ranges, which show OBP scores and their categories:

• .400+ = elite
• .350 – .380 = excellent
• .320 – .340 = above average
• .300 = average
• Below .300 = below average

MLB players who achieve an OBP of .400 or higher are considered elite hitters.

What is SLG (Slugging Percentage)?

In baseball, SLG, or Slugging Percentage, is a statistic that shows how powerful a hitter is. It measures the average total bases a hitter earns per at-bat.

A higher SLG indicates that the player is hitting with more power. Here’s the formula:

SLG = (1B + 2×2B + 3×3B + 4×HR) / AB

Where:

• 1B = Singles
• 2B = Doubles
• 3B = Triples
• HR = Home runs
• AB = At-bats

Wondering what a good SLG is? Here are some common SLG ranges:

• .550+ = elite power hitter
• .500 = excellent
• .450 = above average
• .400 = average
• Below .400 = below average
