Weighted Runs Created Plus (wRC+) is one of the most popular advanced batting metrics in baseball.
It not only estimates how many runs a hitter produces, it also scales the result so 100 equals league average and every point above or below represents one percent.
By adjusting for park and era, wRC+ makes it simple to compare players across seasons and stadiums.
Use this calculator to find any hitter’s value.
This allows fans and analysts to more accurately assess a player’s performance regardless of external factors.
For those looking to dive deeper into the concept, weighted runs created explained highlights how various elements like on-base percentage and slugging percentage are factored into the calculation.
Overall, wRC+ serves as a crucial tool for evaluating offensive contributions in a comprehensive manner.

Frequently Asked Questions
What does wRC+ measure?
wRC+ captures a hitter's total offensive value and scales it so 100 is league average.
Every point above or below 100 equals one percent better or worse than average run creation.
Why is 100 considered average?
The metric is normalized so 100 always represents league average production.
This scaling makes it easy to compare players across years and offensive environments.
What inputs do I need for the calculator?
You need the player's wOBA, plate appearances, the league's wOBA and runs per plate appearance, the current wOBA scale, and an optional park factor to adjust for ballpark effects.
How is park factor applied?
The calculator divides the raw result by the park factor expressed as a percentage.
A park factor above 100 lowers the score, while a factor below 100 raises it.
Can wRC+ be compared across eras?
Yes.
Because wRC+ adjusts for league run environment and park effects, a 130 from 1975 and a 130 from 2023 both signify production 30 percent better than league average.
