WAR Calculator (Wins Above Replacement)

Combine run contributions into Wins Above Replacement.

Batting runs

Baserunning runs

Fielding runs

Positional runs

Replacement runs

Runs per win

WAR 5

Formula: WAR = (sum of run components) ÷ runs per win

Step-by-step with your numbers:

1. Values used:

2. Batting runs = 20

3. Baserunning runs = 3

4. Fielding runs = 5

5. Positional runs = 2

6. Replacement runs = 20

7. Runs per win = 10

9. WAR = 5

Did we solve your problem today?

WAR sums a player's run contributions above a replacement-level player and converts them to wins.

The math behind it

Add the batting, baserunning, fielding, positional and replacement runs, then divide by runs per win (~10).

20+3+5+2+20 = 50 runs ÷ 10 → 5.0 WAR (an All-Star season).

What is replacement level?

The performance of a freely available minor-league/bench player.
