What Is xG (Expected Goals)?

Expected Goals — almost always shortened to xG — is a single number that estimates how likely a shot was to result in a goal, based on everything about the situation it was taken from. Add up every shot's xG for a team across a match, and you get that team's total xG: a measure of the quality of chances it created, independent of whether the shots actually went in.

How it’s calculated

Each shot’s xG (a value between 0 and 1) is modelled from historical data on thousands of past shots with similar characteristics: distance and angle to goal, whether it was a header or hit with the foot, whether it followed a through ball, a cross, a rebound, or a set piece, and how many defenders and the goalkeeper were positioned between the shot and the goal. A tap-in from two yards out with an open net might carry an xG of 0.9; a speculative strike from 30 yards typically sits below 0.05.

How to read it

Compare a team’s xG to the goals it actually scored. A team that scores well above its xG is finishing clinically (or getting lucky); a team that scores well below it is wasteful in front of goal, missing the kind of chances a typical side would convert. Over a single match this gap is often just noise — over a season, it tends to reveal something real about a team or player’s finishing.

What xG doesn’t capture

xG is a pre-shot quality measure — it doesn’t know who’s taking the shot, how good the goalkeeper is, or the scoreline pressure in the moment. A single match’s xG total can be misleading in isolation; it’s most useful as one more data point alongside the actual score, not a replacement for it.
