Goal Scoring Probability
Estimate the probability that a shot results in a goal based on distance, angle, body part, defensive pressure, goalkeeper position, and game state. Compare to league average and get a difficulty rating.
โฝ Why This Metric Matters
Why It Matters
Scoring probability helps analysts and fans quantify chance quality. It explains why some shots are "easier" than others and why conversion rates vary.
How It's Applied
Enter distance (m), angle (ยฐ), body part, pressure level, keeper position, and game state. The model outputs probability, vs league average, and difficulty (1โ10).
Key Insights
- โ~75% of goals come from inside the box.
- โDistance and angle are the strongest predictors.
- โHeaders convert at lower rates than foot shots.

~75% of goals come from inside the penalty area.
Penalties convert at ~76% in top leagues.
Shots from 6m at 60ยฐ convert at 30โ40%.
Goal scoring probability depends on distance, angle, body part, defensive pressure, goalkeeper position, and game state. P(goal) = 1/(1+e^logit). ~75% of goals come from inside the penalty area. Shots from 6m at 60ยฐ convert at 30โ40%; from 25m at 15ยฐ, under 5%. Penalties convert at ~76%.

Key Takeaways
- โข Distance and angle are the strongest predictors; closer and wider = higher probability.
- โข Defensive pressure reduces conversion; low pressure (e.g. counter) adds +0.2 to logit.
- โข Goalkeeper position matters: far from shot adds +0.15; near post reduces โ0.2.
- โข Headers convert at lower rates than foot shots from similar positions.
Did You Know?
How Does Scoring Probability Work?
Logistic Model
logit = 0.5รdistance โ 0.03รangle + pressure + keeper + gameState. P = 1/(1+e^logit). Distance hurts; angle helps.
Modifiers
Pressure: low +0.2, medium โ0.3, high โ0.6. Keeper: near โ0.2, far +0.15. Header โ0.4, other โ0.2.
Difficulty Rating
1โ10 scale: 1 = easiest (prob โฅ 0.5), 10 = hardest (prob < 0.015). Compare to league average 11%.

Probability by Zone
| Zone | Typical Probability |
|---|---|
| Penalty spot (11m, 90ยฐ) | ~65โ76% |
| Tap-in (3m, 75ยฐ) | 40โ50% |
| Edge of box (18m, 25ยฐ) | 5โ8% |
| Long range (28m, 15ยฐ) | 2โ4% |
Frequently Asked Questions
What is goal scoring probability?
The probability that a shot from a given position and context results in a goal. Factors include distance, angle, body part, defensive pressure, goalkeeper position, and game state. ~75% of goals come from inside the penalty area.
How does distance affect scoring probability?
Distance is the strongest predictor. Shots from 6m at a wide angle convert at 30โ40%; from 25m at a narrow angle, under 5%. Each meter further reduces probability in the logistic model.
What is shot difficulty rating?
A 1โ10 scale where 1 = easiest (e.g. tap-in, penalty) and 10 = hardest (long range, narrow angle, high pressure). Based on the computed probability vs league average.
How does goalkeeper position matter?
Keeper near post reduces probability (โ0.2); keeper far from shot adds +0.15 (open goal). Center position is baseline. Goalkeeper positioning is a key xG factor in advanced models.
What is league average conversion rate?
Top leagues average ~11% conversion (shots to goals). Penalties convert at ~76%. Chances inside 6m can exceed 40%. The calculator compares your shot to this 11% baseline.
Do headers have lower probability?
Yes. Headers typically convert at lower rates than foot shots from similar positions. The model applies a โ0.4 modifier for headers due to reduced control and power.
