 On-Base + Slugging Calculator
On-Base + Slugging (OPS) Formula: OBP + SLG = OPS

On-Base + Slugging (OPS) Definition
You don’t need to be in the majors to wonder how to calculate your OPS. Use our on-base + slugging (OPS) calculator to take the guess work out of this number.
You can calculate your own OPS, that of your teammates, or while watching your favorite baseball players in college or professional teams.

What is OPS?
OPS is the measure of your slugging percentage combined with your on-base percentage. Each of these numbers is calculated differently. The numbers are then added together to find your OPS.
Though both of the numbers used in calculating OPS are called percentages, the actual OPS is given as a decimal and not a percent. This is how our calculator presents your answer.

Information Used by the Calculator
To use the on-base + slugging calculator you need to know the following:
• Times at bat
• Hits
• Base on balls (walks)
• Number of times hit by pitches
• Sacrifice flies
• Singles
• Doubles
• Triples
• Home runs
What the Information Means
When you calculate your OPS, the number has less meaning than on-base percentage or slugging percentage alone. Most of the time this data is used to compare players, but high OPS numbers have correlated with some of baseball’s greatest players.
The average for MLB players in 2008 was .749, but players like Babe Ruth, Lou Gehrig, Barry Bonds, and Ted Williams had OPS of over 1.0.
