Isolated Power (ISO) Calculator

The formula for calculating ISO is: SLG - AVG. SLG is calculated as (singles + (2 * doubles) + (3 * triples) + (4 * homeRuns)) / atBats. AVG is calculated as hits / atBats. This formula essentially measures a player's raw power, or their ability to hit for extra bases.

ISO is a measure of a player's extra bases per at bat, calculated as slugging percentage minus batting average. This means that ISO rewards players for hitting doubles, triples, and home runs, rather than just singles.

ISO is an important statistic in baseball as it is a key component of many other statistics, such as slugging percentage and OPS. A high ISO means a player is not only getting hits, but they are getting hits that allow them to advance multiple bases.

Isolated Power (ISO) has been used as an official MLB statistic since the 1980s. It is a measure of a batter's raw power, that is, their ability to hit for extra bases.

ISO has been used in baseball since the 1980s and is a measure of a batter's power-hitting ability.

While ISO is a useful statistic, it does not take into account other aspects of a player's offensive performance, such as their ability to get on base.

If a player has 3 hits in 6 at bats, with 1 single, 1 double, 1 triple, and 1 home run, their ISO would be calculated as follows: ((1 (singles) + (2 * 1 (doubles)) + (3 * 1 (triples)) + (4 * 1 (homeRuns))) / 6 (atBats)) - (3 (hits) / 6 (atBats)).

Barry Bonds holds the record for the highest single-season ISO at .536 in 2001. Babe Ruth holds the record for the highest career ISO at .348.
