# Runs Created (RC) Calculator (Baseball)

## What is Runs Created (RC)?

RC is a baseball metric created by baseball statistician Bill James to estimate the number of runs created by each hitter on a team.
While runs are the statistic in baseball that win games, it is difficult to figure out exactly who was responsible for each run as individual statistics add up to create runs. Runs created was developed to attempt to showcase individual run creation responsibility.

## How to calculate Runs Created

There are 4 variations of the Runs Created formula:
Runs Created – Basic = ((Hits + Walks) x Total Bases) / (At Bats + Walks)
Runs Created (Stolen Base Method) = ((Hits + Walks – Caught Stealing) x (Total Bases + (0.55 x Stolen Bases))) / (At Bats + Walks)
Runs Created (Technical Method) = ((Hits + Walks – Caught Stealing + Hit by Pitch – Ground into Double Play) x (Total Bases x (0.26 x (Walks – Intentional Walks + Hit by Pitch)) + (0.52 x (Sacrifice Hits + Sacrifice Flies + Stolen Bases)))) / (At Bats + Walks + Hit by Pitch + Sacrifice Hits + Sacrifice Flies)
Runs Created (2002 version):
A = Hits + Walks – Caught Stealing + Hit by Pitch – Ground Into Double Play
B = (1.125 x Singles) + (1.69 x Doubles) + (3.02 x Triples) + (3.73 x Home Runs) + (0.29 x (Walks – Intentional Walks + Hit by Pitch)) + (0.492 x (Sacrifice Hits + Sacrifice Flies + Stolen Bases)) – (0.4 x Strikeouts)
C = At Bats + Walks + Hit by Pitch + Sacrifice Hits + Sacrifice Flies
D = ((2.4 x C) + A) x ((3 x C) + B))
Runs Created (2002) = (D / (9 x C)) – (0.9 x C)

## Example

A batter has 164 hits, 22 walks, 255 total bases, and 520 at bats.
Using the Basic Runs created formula:
Runs Created (Basic) = ((164 + 22) x 255) / (520 + 22)
Runs Created (Basic) = (186 x 255) / 542
Runs Created (Basic) = 47430 / 542
Runs Created (Basic) = 88
Using the basic formula, the batter would have created 88 runs.
