About

In high-stakes matches, the margin between victory and defeat often boils down to a penalty shootout. This tool utilizes binomial probability distributions to calculate the likelihood of a shootout being decided within the standard five rounds versus extending into sudden death. Analysts and enthusiasts use this data to evaluate the volatility of "clutch" moments, where the psychological pressure meets statistical variance. By inputting historical conversion rates, users can model scenarios similar to extended finals where consistency dictates the outcome.

Formulas

The probability of a specific scoreline after 5 rounds is derived from the Binomial Mass Function:

P(k) = nk p^k (1 − p)^n−k

Sudden death probability is the sum of probabilities where scores are equal after n=5 kicks.

Reference Data

Outcome	Formula Ref	Probability Range (Typ)
Decided in 5 Rounds	P(X ≠ Y)	0.75 - 0.90
Sudden Death	P(Tie @ 5)	0.10 - 0.25
Conversion Rate	p	0.70 - 0.85

Frequently Asked Questions

It relies on the Binomial Distribution, assuming each penalty kick is an independent event with a fixed probability of success (conversion rate) for each team.

If both teams have very high or very low conversion rates, the likelihood of a tie increases. If one team is significantly better, the match is more likely to end early.

This model is purely statistical based on conversion rates. It does not factor in psychological advantages of shooting first unless you manually adjust the conversion rates to reflect that bias.
