Baseball OPS Calculator
Calculate a player's On-base Plus Slugging (OPS) and compare it against league benchmarks.
Calculate On-base Plus Slugging (OPS)
Use this **baseball OPS calculator** to determine a player's combined offensive value. OPS is a powerful metric that adds On-Base Percentage (OBP) and Slugging Percentage (SLG).
Total hits (singles, doubles, triples, home runs).
Total hits resulting in two bases.
Total hits resulting in three bases.
Total hits resulting in four bases (a home run).
Total bases on balls.
Total times hit by a pitch.
Official plate appearances (excludes walks, HBP, sacrifices).
Fly balls allowing a runner to score, not counting as an at-bat.
How This OPS Calculator Works
Our **Baseball OPS Calculator** provides a comprehensive measure of a player's offensive value by combining their ability to get on base with their power-hitting capabilities. Here's how it works:
- Input Player Statistics: Enter the required values for Hits (H), Doubles (2B), Triples (3B), Home Runs (HR), Walks (BB), Hit-by-Pitch (HBP), At-Bats (AB), and Sacrifice Flies (SF).
- Calculate OBP: The calculator first determines On-Base Percentage (OBP) using the formula: $(H + BB + HBP) \div (AB + BB + HBP + SF)$.
- Calculate SLG: Next, Slugging Percentage (SLG) is calculated using the formula: $(1B + 2 \times 2B + 3 \times 3B + 4 \times HR) \div AB$. (Note: Singles (1B) are derived from Total Hits minus 2B, 3B, and HR).
- Calculate OPS: Finally, OPS is derived by simply adding OBP and SLG: $OPS = OBP + SLG$.
- View Results & Comparison: The calculated OBP, SLG, and OPS are displayed, with OPS classified into performance tiers. A dynamic bar graph visually compares your OPS to simulated league averages.

This tool is invaluable for **baseball analysts**, **fantasy league participants**, and anyone keen on understanding advanced **baseball metrics**.
Understanding OPS: On-base Plus Slugging
OPS is a cornerstone of modern **baseball analytics**, providing a single number that encapsulates a hitter's overall offensive production.
On-Base Percentage (OBP)
Measures a player's ability to get on base through hits, walks, or hit-by-pitches. It's about avoiding outs.
Formula: $(H + BB + HBP) \div (AB + BB + HBP + SF)$
Slugging Percentage (SLG)
Measures a player's power by calculating the total bases per at-bat. It values extra-base hits more.
Formula: $(1B + 2 \times 2B + 3 \times 3B + 4 \times HR) \div AB$
On-base Plus Slugging (OPS)
The sum of OBP and SLG. It provides a quick, comprehensive view of a hitter's overall offensive production.
Formula: $OBP + SLG$
Frequently Asked Questions (FAQs) about OPS
OPS stands for **On-base Plus Slugging**. It's a key **baseball statistic** that combines two important offensive metrics: On-Base Percentage (OBP) and Slugging Percentage (SLG).
OBP measures a player's ability to avoid making an out and get on base (patience and contact). SLG measures a player's power and ability to hit for extra bases. By combining them, OPS gives a more complete and holistic picture of a hitter's overall offensive value than either statistic alone.
Yes, an OPS of .800 is generally considered **above average** to very good in modern baseball. Elite players often exceed 1.000 OPS. Our **OPS classification** table provides a detailed breakdown of what different OPS ranges signify.
In a live application, league average OPS would typically be fetched weekly or even daily from official MLB or reputable sports statistics APIs (like StatMuse). For this calculator, the league average OPS values are simulated for demonstration purposes.
OPS+ is an advanced version of OPS that adjusts for external factors such as the player's home ballpark and the overall league environment. An OPS+ of 100 is considered league average. A player with an OPS+ of 120 is 20% better than the league average offensively, while an OPS+ of 80 is 20% worse.
