Every football (soccer) calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
16 calculators in this section
- Clean Sheet and Goals Conceded Rate CalculatorClean sheet percentage, goals conceded per match and goals conceded per 90 minutes in association football — and the two published definitions of a clean sheet, which do not agree about a substituted goalkeeper.
- Elo Rating Change CalculatorExpected score and the new rating after one association football match, from two Elo ratings, a K value and the result. K and the scale divisor are inputs, because no implementation's values are universal.
- Expected Goals (xG) Difference CalculatorxG difference, xG per shot, and the gap between goals and expected goals in an association football match — from your own provider's figures. This page does not model xG, because no provider's model is published.
- Goal Difference and Tie-Breaker InterpreterTwo teams in association football finish level on points — which one is ranked above? The answer depends on the competition, because the published tie-breaking sequences do not agree with each other. This runs three of them side by side.
- Goals Per 90 Minutes CalculatorGoals, assists and goal involvements per 90 minutes from minutes played in association football — the normalisation that lets a substitute be compared with a starter, and the small-sample problem it creates.
- League Table Points CalculatorTotal a team's league points in association football from its wins, draws and losses. The points per result are inputs, because three points for a win is a competition's rule with a date, not a property of the game.
- Offside Law InterpreterWas it offside? Law 11 of the IFAB Laws of the Game asks two separate questions — was the player in an offside position, and did the player then become involved in play — and only both together are an offence in association football.
- Pass Completion and Passing Accuracy CalculatorPass completion percentage in association football from completed and attempted passes, with passes per 90 minutes beside it. Opta publishes this definition in words, which is more than can be said for possession percentage.
- Penalty Shootout Sequence InterpreterIs the penalty shoot-out already over? Law 10 of the IFAB Laws of the Game stops it as soon as one side cannot be caught. Enter the state of an association football shoot-out and this works out whether any kicks are left.
- Pitch Dimensions and Markings InterpreterIs an association football pitch a legal field of play? Law 1 of the IFAB Laws of the Game sets a permitted range rather than a size, with a narrower range for internationals — so there is no standard pitch to check against.
- Points Needed for Safety or Title CalculatorHow many wins are still needed to reach a points target in an association football league, and whether the target is still mathematically reachable. The arithmetic is exact; the target is your number, because no body publishes one.
- Points Per Game and Projected Finish CalculatorPoints per match so far in an association football season, and the final total that rate would reach. The rate is exact; the projection assumes two things that are not true, and this page says which.
- Round Robin Fixture Count CalculatorHow many matches a round robin takes in association football: single or double, one group or many, with the matchdays and byes an odd entry needs and the knockout bracket the qualifiers imply.
- Shot Conversion and Shots on Target CalculatorShot conversion, shooting accuracy and shots per goal in association football — and the published definition of “on target”, under which a shot that hits the bar and stays out is not on target at all.
- Substitution and Squad Limits InterpreterCan this team make another substitution, and does it spend one of its windows? Law 3 of the IFAB Laws of the Game caps association football at five substitutes and three substitution opportunities, plus half-time.
- Two-Legged Tie and Away Goals CalculatorSettle a two-legged knockout tie in association football under both rules at once: the aggregate, the away goals, and the two different survivors they can produce. UEFA abolished the away goals rule on 24 June 2021.
