World Cup 2026 xG tool
World Cup 2026 xG to Odds Calculator
Use this World Cup 2026 xG to odds calculator to convert projected expected goals into fair probabilities for
1X2, over/under 2.5, BTTS and correct score markets.
Expected goals are not a prediction by themselves. They are an input. This calculator turns those inputs into
market-style probabilities so you can compare your model view with bookmaker prices.
Tournament note: World Cup 2026 uses a 48-team format with 104 matches, 12 groups and a Round of 32.
See FIFA’s format explainer and group qualification rules.
Enter projected expected goals for both teams and convert them into fair probabilities for 1X2, over/under 2.5, BTTS and top correct scores.
Add bookmaker odds for key markets to compare break-even probability with the model baseline.
Enter match assumptions
The calculator assumes 90-minute expected goals. For knockout matches, check whether the market settles in regulation time only or includes extra time.

What this xG to odds calculator does
The calculator starts with projected expected goals for both teams. It then estimates the probability of each
scoreline and converts that score matrix into betting markets.
- 1X2 probabilities: Team A win, draw and Team B win;
- over/under 2.5 goals probabilities;
- BTTS Yes and BTTS No probabilities;
- top correct score probabilities;
- fair decimal and American odds;
- basic edge comparison against bookmaker odds.
How xG becomes betting odds
A projected xG number estimates how many goals a team should score on average from its chance quality. To convert
xG into odds, the calculator estimates how often each team scores 0, 1, 2, 3 or more goals, then combines those
goal distributions into match outcomes.
| Output | How it is derived | Use case |
|---|---|---|
| 1X2 | All scorelines where Team A wins, draws or loses are summed. | Compare match result odds. |
| Over/under 2.5 | Total-goal probabilities are summed above or below 2.5 goals. | Check totals markets. |
| BTTS | The probability both teams score at least once is calculated from each team’s xG. | Check both-teams-to-score prices. |
| Correct score | Each exact scoreline receives its own probability. | Check high-variance exact-score markets. |
| Fair odds | Probability is converted into decimal or American odds. | Compare model price with bookmaker price. |
World Cup 2026 use cases
World Cup matches are not all priced the same way. A group-stage opener, a final group match and a knockout match
can have different tactical incentives even if the teams have similar strength ratings.
- Group-stage openers: use xG to compare cautious market pricing against attacking potential.
- Final group matches: adjust xG assumptions for qualification incentives.
- Knockout matches: check whether markets settle in 90 minutes or include extra time.
- Favourite vs underdog: separate win probability from over/under or BTTS probability.
- Low-total games: compare 0-0, 1-0, 0-1 and 1-1 score clusters.
- High-tempo games: compare over 2.5, BTTS Yes and correct-score alternatives together.
Why xG does not guarantee value
xG is a useful modelling input, but it is not automatically a betting edge. The bookmaker market may already
account for team strength, tactical style, injuries and expected match tempo.
Value only exists if your xG assumptions are more accurate than the market’s implied assumptions and the available
price is still better than your fair odds.

Important limitation
The calculator uses projected xG and a Poisson-style score model. Real matches are affected by red cards,
penalties, team news, tactical changes, weather, fatigue, travel and tournament incentives.
The output is only as reliable as the xG inputs. If the xG projection is wrong, the fair odds will also be wrong.
World Cup 2026 xG to odds FAQ
What does xG mean?
xG means expected goals. It estimates the number of goals a team should score on average based on the quality of
its chances.
Can xG be converted into betting odds?
Yes. A model can convert projected xG into score probabilities, then aggregate those scorelines into 1X2,
over/under, BTTS and correct-score probabilities.
Does this calculator include extra time?
No. The calculator is based on 90-minute expected goals. For knockout matches, check whether the bookmaker market
includes extra time or settles on regulation time only.
Is xG enough to find value bets?
No. xG is only one input. You still need to compare the model probability with no-vig market probability and check
whether your assumptions are better than the market’s assumptions.
Why do xG-based odds differ from bookmaker odds?
Bookmakers may use broader information than a simple xG model, including team news, market action, player ratings,
tactical expectations and risk management. Differences are a reason for investigation, not automatic value.
