Enter a player's Weighted Runs Created (wRC), the league average wRC, and the park factor to calculate wRC+ — the park- and league-adjusted offensive metric where 100 equals league average. Every point above or below 100 means the player is that many percentage points better or worse than a league-average hitter. Also try the Slugging Percentage Calculator (SLG).

A wRC+ of 100 represents exactly league-average offensive production. Every point above 100 means the player is that percentage point better than average — so a wRC+ of 130 means the hitter is 30% better than a league-average hitter. See also our use the ERA+ Calculator.
wRC+ is calculated as (Player wRC / League Average wRC) / Park Factor × 100. This adjusts the raw wRC figure for the run-scoring environment of the player's home ballpark and the overall league average, putting all hitters on a common 100-point scale.
A park factor above 1.00 indicates a hitter-friendly ballpark (like Coors Field), so a player's raw wRC is deflated slightly when computing wRC+. Conversely, a park factor below 1.00 boosts the wRC+ of players who hit in pitcher-friendly parks, recognizing that their raw numbers understate their true offensive value.
Yes — that is one of wRC+'s key strengths. Because it normalizes performance to league average, a wRC+ of 150 means the same thing whether a player achieved it in the high-offense 1990s or the lower-offense 2010s. However, you should still be aware of other contextual differences between eras, such as changes in the quality of pitching and fielding. You might also find our WAR (Wins Above Replacement) useful.
No. wRC+ is a purely offensive metric designed to measure a hitter's plate contributions relative to league average. For evaluating pitchers, different stats such as ERA+, FIP, or xFIP are more appropriate.
In a small number of plate appearances, random variance can inflate or deflate a player's wRC significantly. A hitter may post a very high or very low wRC+ over 50 PAs simply due to luck. Larger samples — generally 300+ PAs — are needed for wRC+ to be a reliable indicator of true offensive talent.
Generally, a wRC+ of 140 or above is considered excellent and typical of All-Star-caliber hitters. A wRC+ of 160+ is elite and reflects MVP-level offensive production. Below 80 is considered well below average, while 80–95 is below average, and 95–105 is near league average.
Both wRC+ and OPS+ are park- and league-adjusted offensive metrics scaled to 100 for league average. The key difference is that wRC+ uses weighted values for each offensive outcome (based on run-expectancy research), making it more precise. OPS+ adds on-base percentage and slugging percentage together, which can over- or under-weight certain contributions.
