Are these real betting odds?
No. This is a simplified teaching model based on goal difference and time remaining. Real bookmaker and analytics models use far more data, so treat these numbers as illustrative.

Goal Impact on Win Probability Calculator
Estimate how scoring (or conceding) a goal shifts win probability, using a simplified logistic model of goal difference and time remaining. Illustrative, not official odds.
P(win) ≈ logistic(k × goal_diff × time_weight) — illustrative model
Frequently asked questions
Why does the same goal matter more late in a game?
Because there is less time for the opponent to respond. The model weights time remaining, so a goal in the 85th minute swings the win probability more than one in the 20th.
What is a logistic curve and why use it?
It is an S-shaped function that keeps probabilities between 0 and 100% and changes fastest in the middle. It naturally captures how a tight game is more uncertain than a blowout.
Can I model conceding a goal?
Yes, choose 'against' and it lowers your goal difference, showing how much win probability you shed.
Why is this useful even if it is simplified?
It builds intuition for why teams defend leads differently late on, and why a single goal can feel decisive. The shape of the swing is realistic even though the exact numbers are not official.
