Poisson Distribution Formulas
The mathematics behind correct score calculation
Poisson Formula
λ = expected goals, k = actual goals, e = 2.71828
Score Probability
P(2-1) = P(Home=2) × P(Away=1)
Fair Odds
12.5% probability = 100/12.5 = 8.00 fair odds
xG Interpretation
1.5 xG = average 1.5 goals expected
How Correct Score Calculator Works
Enter Expected Goals
Input the xG (expected goals) for both home and away teams. Use data from sites like Understat, FBref, or bookmaker projections.
Poisson Calculation
The calculator applies Poisson distribution to each team's xG separately, calculating the probability of scoring 0, 1, 2, 3+ goals.
Score Matrix
Probabilities for each team are combined to create a full score matrix showing all possible score outcomes.
Fair Odds
Each score probability is converted to fair odds. Compare with bookmaker odds to find value betting opportunities.
Common xG Scenarios
Typical expected goals ranges for different match types
| Match Type | Home xG | Away xG | Most Likely |
|---|---|---|---|
| Low scoring (defensive) | 0.8 | 0.7 | 1-0 / 0-0 |
| Balanced match | 1.5 | 1.2 | 1-1 / 2-1 |
| Home dominant | 2.2 | 0.8 | 2-0 / 2-1 |
| High scoring | 2.5 | 2.0 | 2-2 / 3-2 |
| Away dominant | 0.9 | 1.8 | 0-2 / 1-2 |
Pro Tips
Use Recent xG Data
Use xG from the last 5-10 matches for accuracy. Season-long averages may not reflect current form.
Account for Home Advantage
Home teams typically score 0.2-0.3 more xG than away. Factor this into your xG inputs if using neutral data.
Compare Multiple Scorelines
Don't just bet the most likely score. Look for value across 3-4 probable scorelines for better coverage.
