wRC+ Calculator. 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 WHIP 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.
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. You might also find our Spin Movement Index — Baseball Spin Rate useful.
