wOBA Calculator
Weighted On-Base Average (wOBA) is a version of on-base percentage that accounts for how a player reached base—instead of simply considering whether a player reached base. It is scaled to look like OBP, where .320 is roughly average and .400 is elite.
Assumptions
This calculator uses generalized linear weights (approximately scaled to recent seasons): BB=0.69, HBP=0.72, 1B=0.88, 2B=1.23, 3B=1.55, HR=1.98. Actual MLB weights change slightly every season based on league-wide run environments.
