Slugging Percentage Calculator

Slugging percentage (SLG) measures the total number of bases a player records per at-bat, heavily weighing extra-base hits like doubles, triples, and home runs over standard singles. The standard formula is expressed as: SLG = (Singles + (2 * Doubles) + (3 * Triples) + (4 * Home Runs)) / At Bats. Unlike batting average which treats all hits equally, slugging percentage accurately highlights a hitter's ability to drive the ball with power.

Imagine a player who records the following statistics over the course of a season: 400 at-bats, 80 singles, 30 doubles, 5 triples, and 20 home runs. First, calculate the total bases: (80 * 1) + (30 * 2) + (5 * 3) + (20 * 4) = 80 + 60 + 15 + 80 = 235 total bases. Next, divide this sum by the total at-bats: 235 / 400 = 0.5875. The player's slugging percentage is an impressive .588.

Always ensure your at-bat count excludes walks, hit-by-pitches, and sacrifice flies, as these do not technically count as official at-bats in traditional baseball statistics. Compare slugging percentages within the same league or era, as pitcher dominance and ballpark dimensions heavily influence offensive output. Pair this metric with on-base percentage (OBP) to get a complete picture of a hitter's true offensive value.
