Soccer xG vs Actual Goals
Compare expected goals (xG) to actual goals (over/underperforming finisher).
Goals to xG = 9:7 (1 as decimal).
xG
Goals/xG > 1.0 = overperforming chances. Sustained 1.2+ over a season = elite finisher (Haaland, Mbappé). Below 0.85 = unlucky or wasteful.
Worked Example
18 Goals to 14 xG
- a
- 18
- b
- 14
- Result
- 9:7 (1.29)
18 / 14 = 1.29. Simplified: 9:7.

Frequently Asked Questions
How is the Soccer xG vs Actual Goals computed?
Goals divided by xG, plus a simplified ratio (e.g., 4:3) using greatest common divisor. Both decimal and ratio forms are useful in different contexts: decimal for math, ratio form for comparisons or recipe scaling.
What does Goals:xG mean?
It's a comparison: for every xG unit, you have a corresponding amount of Goals. Useful when the absolute numbers matter less than the proportion (e.g., reading 8:1 LTV/CAC immediately tells you the unit economics are healthy without needing the dollar amounts).
Why simplify the ratio?
4:3 is more readable than 200:150. The simplified form (using greatest common divisor) preserves the proportion while making it easier to interpret. Common simplified ratios: 16:9 (widescreen), 4:3 (legacy displays), 3:1 (LTV:CAC for SaaS).
When is a ratio more useful than the absolute values?
Comparison across scales. A $1B company and a $1M company can both have a 3:1 LTV:CAC; the ratio reveals comparable unit economics regardless of scale. Use ratios for benchmarking; use absolute numbers for budgeting.
