Weighted Runs Created (wRC) Calculator

Weighted Runs Created is one of the most intuitive all-in-one statistics for estimating a hitter’s total offensive value.

By adjusting for league run environment and ballpark factors, it turns raw production into a scalable runs figure that aligns with real-life scoring.

Enter a player’s weighted on-base average, plate appearances, and league benchmarks below to see precisely how many runs their bat is projected to create, independent of team context overall.

Weighted Runs Created FAQ

What is wRC?

Weighted Runs Created (wRC) converts a player’s total offensive contribution into the number of runs they generated, adjusted for league and park effects.

Why does the calculator need league values?

League averages anchor the calculation so that a player’s production is measured against the current offensive environment instead of a fixed historical baseline.

What is the wOBA scale?

The wOBA scale is a yearly conversion factor that transforms weighted on-base average into runs.

It keeps the statistic aligned with how many runs are actually scored in a season.

Does wRC adjust for ballparks?

Full wRC plus (wRC+) accounts for park factors, but raw wRC shows how many runs a player created independent of where the games were played.

How accurate is this simplified calculator?

The tool follows the core FanGraphs formula and is precise when you provide up-to-date league inputs.

Minor rounding differences may appear compared with official leaderboards.
