Balls hit hard (i.e. with a high [[exit velocity]]) in the [[sweet spot (sports)|sweet spot]] produce higher wOBA.<ref>{{cite news|first=Ben|last=Clemens|title=A Sweet Spot by Any Other Definition|date=February 25, 2020|work=FanGraphs|url=https://blogs.fangraphs.com/a-sweet-spot-by-any-other-definition/|access-date=March 14, 2024}}</ref>

=== 2019 Formula ===
Per [[Fangraphs]], the formula for wOBA in the 2019 season was:<ref name=":0" />
<math>wOBA=\frac{(0.69*NIBB) + (0.719*HBP) + (0.87*\mathit{1}B) + (1.217*\mathit{2}B) + (1.529*\mathit{3}B) + (1.94*HR)}{AB + BB - IBB + SF + HBP}
</math>
where:
* ''NIBB'' = ''<u>Non-intentional</u> [[Base on balls|bases on balls]]''
* ''HBP'' = ''[[Hit by pitch]]''
* ''1B'' = ''[[Single (baseball)|Single]]''
* ''2B'' = ''[[Double (baseball)|Double]]''
* ''3B'' = ''[[Triple (baseball)|Triple]]''

=== 2018 Formula ===
The formula for the 2018 season was:<ref name=":0" />
<math>wOBA=\frac{(0.69*NIBB) + (0.72*HBP) + (0.88*\mathit{1}B) + (1.247*\mathit{2}B) + (1.578*\mathit{3}B) + (2.031*HR)}{AB + BB - IBB + SF + HBP}
