Baseball Slugging Percentage Calculator
Calculate slugging percentage and OPS from a batter’s hit distribution.
About Baseball Slugging Percentage Calculator
Slugging weights hits by the bases they produce, so it captures power in a way batting average cannot. Isolated power strips out singles entirely to isolate extra-base hitting. OPS combines getting on base with power in a single number, and it correlates with run production far better than batting average does.
Formula

Slugging = total bases ÷ at bats, where a double counts two bases and a home run four
