BB/K Calculator

Definition – What is Walk to Strikeout Ratio?

BB/K is a batting ratio that shows the ratio of walks for each strikeout.

A higher number is considered better, as it means that the batter can recognize pitches in and outside of the strike zone, as well as more likely to get on base.

It is the inverse of the hitting ratio strike to walk ratio (K/BB).

Formula – How to calculate BB/K

BB/K = Walks ÷ Strikeouts


If a batter has 56 walks and 77 strikeouts, then:
BB/K = 56 ÷ 77
BB/K = 0.72
On average, this batter is walked 0.72 times for each time they are struck out.
