Football Win Probability Calculator
This turns two team ratings into a win probability for football, using the Elo approach. Enter your team's rating and the opponent's.
Calculate football win probability
Fill in the fields and select Calculate.
What you'll need
To use the football win probability calculator, have these figures ready:
- Your team rating — for example, 1800.
- Opponent rating — for example, 1700.
The calculator then returns the win probability the moment you press calculate.
How it works
Win probability = 1 ÷ (1 + 10^((opponent rating − your rating) ÷ 400))
You enter the your team rating and opponent rating, and the calculator returns the win probability using the formula above.
When to Use
Use the football win probability calculator to estimate the likelihood of winning based on Elo ratings or historical performance. It is commonly used before matches for prediction, during matches for live win probability updates, and by sports analysts to evaluate team strength across different competitions and seasons.
What the result tells you
A win probability near half marks an even contest, while a figure in the 70s or above signals a clear favourite. Because football has so many draws, treat the number as the share of decisive outcomes that fall your way rather than a flat chance of victory. It also ignores home advantage and form, which you can weigh on top.
Benchmarks & Interpretation
Here is how typical results are categorized and interpreted:
| Value / Range | Rating | Description |
|---|---|---|
| Below 25% | Underdog | The team is not favoured. An upset would be needed. |
| 25 – 40% | Slight underdog | Competitive but facing a stronger team. |
| 40 – 60% | Even match | A closely matched contest where either team could win. |
| 60 – 75% | Favourite | The team is expected to win but the match is not one-sided. |
| 75%+ | Strong favourite | A dominant team facing weaker opposition. |
Pro Tips & Advice
Win probability models are useful for strategic planning but should not be taken as certainties. Home advantage typically adds 5-10 percentage points to a team's win probability. Current form, injuries, and tactical matchups are not always captured by Elo-based models. For betting or fantasy purposes, compare the model's win probability with bookmaker odds to identify potential value bets where the market disagrees with the model.
Step by step
- Enter the your team rating.
- Enter the opponent rating.
- Select Calculate to read the win probability.
Worked example
A team rated 1800 against one on 1700 has a win probability of about 64 percent before draws are considered.
Frequently asked questions
How is the football win probability worked out?
Win probability = 1 ÷ (1 + 10^((opponent rating − your rating) ÷ 400)). This turns two team ratings into a win probability for football, using the Elo approach. Enter your team's rating and t…
Does this allow for draws?
The basic Elo figure is a win versus not win probability. In football, where draws are common, treat it as the share of the non draw outcomes that fall your way.
How does the Elo rating system work in football?
Elo ratings assign each team a numerical rating that increases after wins and decreases after losses. The magnitude of the change depends on the result's unexpectedness — beating a higher-rated team earns more points than beating a lower-rated one.
Are Elo-based predictions accurate?
Over a large sample, Elo models predict match outcomes correctly about 50-55% of the time for the correct result (win/draw/loss). They are better at identifying favourites than predicting exact outcomes.
