# Runs Created (RC) | Formula & Calculator

LAST UPDATE: September 24th, 2020

## Definition – What is Runs Created (RC)?

RC is estimates the number of runs created for a hitter. A higher number of runs created represents a batter who has contributed more to the runs made by their team.

Runs Created was invented by baseball statistician Bill James.

## Formula – 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.
