NinetyFree football calculators
Small tools that do one job: turn odds into probabilities, turn expected goals into match chances, and project a league total. They run in your browser and keep nothing.
Odds to probability
Turn 1X2 odds in decimal, fractional or American format into win, draw and loss probabilities, and strip out the bookmaker margin to see the fair numbers.
Match calculator (xG)
Enter each team’s expected goals and get win, draw and loss probabilities, expected points, the most likely scorelines and the chance of 3+ goals. Free, runs in your browser.
Points calculator
Enter a team’s record so far to see its points per game, projected final total and the points needed for a target such as 40 to stay up or 70 for Europe.
What these tools are for
Football numbers are easy to misread. A price of 2.10 looks like a number but is really a probability with a bookmaker’s margin hiding inside it. An expected goals figure of 1.6 looks like a forecast but says nothing about how likely a win is until you turn it into a distribution of scorelines. A team on 21 points after 13 games has a pace, but not a prediction. Each calculator here does one of those conversions in the open, shows its working and tells you where the maths stops being reliable.
They run entirely in your browser: nothing you type is sent anywhere or stored. They are not betting tools and carry no betting links. The explanations behind them are in the guides, and the live tables, fixtures and results they apply to are on the competition pages.
