Clean Sheet and Goals Conceded Rate Calculator
Clean Sheet and Goals Conceded Rate Calculator
Clean 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.
Clean sheets and the concession rate
Clean sheets ÷ matches14 clean sheets in 38 matches, 38 goals conceded, 3,330 minutes played
Formula
Goals conceded per match = goals conceded ÷ matches played
Goals conceded per 90 = (goals conceded ÷ minutes played) × 90
- a substituted goalkeeper, where the two sources part
- Sofascore adds a condition: “For a goalkeeper to be credited with a clean sheet in their seasonal statistics they must have played the entirety of the match, completing all 90 minutes on the field.” The Premier League’s own Golden Glove page states no such condition anywhere, and the award is simply “the goalkeepers who have kept the most clean sheets”. So a competition and a statistics provider can disagree about the same goalkeeper’s season. Both are printed here rather than reconciled
- why the per-match and per-90 rows differ
- because minutes played and matches played are different counts. They agree exactly when the minutes are 90 times the matches and diverge the moment a goalkeeper is substituted, sent off, or on the pitch for part of a match. The 90 itself is Law 7 of the IFAB Laws of the Game: “A match lasts for two equal halves of 45 minutes.” See the goals per 90 minutes calculator for the same normalisation at the other end of the pitch
- the Premier League’s own use of this rate
- before 2013/14 the Golden Glove tie-break was, in the Premier League’s words, “the goalkeeper with highest ratio of clean sheets for matches played” — precisely the headline figure above. Since 2013/14 a tie is shared instead, and the Premier League records shared awards in 2013/14, 2021/22 at twenty clean sheets each, and 2024/25
- what no source publishes
- a benchmark. No published figure exists for a good clean sheet rate or a good concession rate, because both depend on the team in front of the goalkeeper far more than on the goalkeeper. None is invented here
Worked example
14 clean sheets in 38 matches, 38 goals conceded, 3,330 minutes played
14 ÷ 38 = 0.3684, so the clean sheet rate is 36.8%
38 − 14 = 24 matches in which a goal was conceded
38 ÷ 38 = 1.000 goals conceded per match
38 ÷ 3,330 × 90 = 1.027 goals conceded per 90 minutes — not the same figure, because 3,330 minutes is not 90 × 38
Set the minutes to 3,420, which is 90 × 38, and the two rates become identical at 1.000. That is the only condition under which they agree
3,330 ÷ 38 = 88 minutes per goal conceded, and 3,330 ÷ 90 = 37.00 full 90s across thirty-eight appearances
Halve the matches to 19 with the clean sheets unchanged and the rate doubles to 73.7%; double both to 28 in 76 and it does not move
Enter more clean sheets than matches, or zero matches, and the panel shows nothing rather than an impossible rate
Two published definitions of a clean sheet, and they disagree
| Source | What it says | Consequence for a substituted goalkeeper |
|---|---|---|
| Sofascore | “A clean sheet occurs when a player or team successfully prevents the opposing team from scoring throughout the entire duration of a match”, and for a goalkeeper’s season figure “they must have played the entirety of the match, completing all 90 minutes on the field” | No clean sheet. A goalkeeper who comes off at 80 minutes in a goalless match is not credited |
| Premier League | “Each season the Premier League rewards the goalkeepers who have kept the most clean sheets with the Golden Glove award.” The page states no minimum-minutes condition | Not addressed. Nothing on the page excludes a partial appearance |
| Premier League, before 2013/14 | A tie for the Golden Glove went to “the goalkeeper with highest ratio of clean sheets for matches played” | The competition’s own tie-break was this page’s headline rate |
| Premier League, since 2013/14 | “If more than one goalkeeper records the highest number of clean sheets, the award is shared” | Shared in 2013/14, in 2021/22 at twenty each, and in 2024/25 |
Where the per-match rate and the per-90 rate agree, and where they do not
| Matches | Minutes | Goals conceded | Per match | Per 90 | Minutes per goal |
|---|---|---|---|---|---|
| 38 | 3,420 | 38 | 1.000 | 1.000 | 90 |
| 38 | 3,330 | 38 | 1.000 | 1.027 | 88 |
| 38 | 3,420 | 60 | 1.579 | 1.579 | 57 |
| 19 | 1,710 | 19 | 1.000 | 1.000 | 90 |
| 36 | 3,100 | 30 | 0.833 | 0.871 | 103 |
| 38 | 3,420 | 0 | 0.000 | 0.000 | no answer — nothing was conceded |
A hit rate, a volume rate, and two definitions of the word
A clean sheet on this page means a clean sheet in association football — soccer — where a goalkeeper and ten outfield players defend one goal for two halves of 45 minutes. Shutouts in ice hockey and other codes are counted against different match lengths by different bodies and are not the same figure. A clean sheet count answers one question and a concession rate answers another, and a goalkeeper’s season needs both. Fourteen clean sheets in thirty-eight matches is a hit rate of 36.8%. Thirty-eight goals in thirty-eight matches is exactly one a game, and it is entirely compatible with those fourteen shut-outs, because goals arrive in clusters rather than one a week. Neither figure is more honest than the other; quoting only one of them is.
The word itself has two published definitions and they do not agree. Sofascore states that a clean sheet is “when a player or team successfully prevents the opposing team from scoring throughout the entire duration of a match”, and then adds a condition for a goalkeeper’s season figures: “they must have played the entirety of the match, completing all 90 minutes on the field.” The Premier League’s own page about the Golden Glove, which is awarded to “the goalkeepers who have kept the most clean sheets”, states no minimum-minutes condition anywhere. So a goalkeeper substituted on 80 minutes of a goalless match has a clean sheet under one convention and not under the other, and over a season that can move a count. Both are printed above rather than reconciled.
The Premier League has used this page’s headline rate itself. Until 2013/14 a tie for the Golden Glove was broken, in its own words, by “the goalkeeper with highest ratio of clean sheets for matches played” — exactly the figure above. Since 2013/14 the award is simply shared, and the Premier League records shared awards in 2013/14, in 2021/22 at twenty clean sheets each, and in 2024/25. That is a competition deciding that a rate was the wrong tie-break and a raw count the right one, which is worth knowing before using either.
The two concession rates need separating too. Goals conceded per match divides by appearances; goals conceded per 90 minutes divides by minutes and scales to one match’s worth of football. They are the same number only when the minutes played are exactly 90 times the matches played, and a single substitution breaks that. There is no published benchmark for either rate, and none is invented here: a concession rate measures the team in front of the goalkeeper at least as much as the goalkeeper. For the shots that produced those goals from the other side, the shot conversion and shots on target calculator works the attacking end. No governing body publishes any of the figures on this page. Each one is a statistics provider’s definition, and a provider’s definition is a convention rather than a rule: two of them can watch the same match and count it differently, and neither is wrong. So take every number here from one source, say which source it was, and do not read a figure from one provider against a figure from another.
Frequently asked questions
What is a clean sheet in football?
A match in which a team or goalkeeper concedes no goals. Sofascore publishes it as preventing the opposition from scoring “throughout the entire duration of a match”. An own goal by a team-mate ends a clean sheet; a goal in a penalty shoot-out does not, because the shoot-out is not part of the match.
Does a substituted goalkeeper get a clean sheet?
It depends which source you use, and the two read for this page disagree. Sofascore requires the goalkeeper to have “played the entirety of the match, completing all 90 minutes on the field”. The Premier League’s Golden Glove page states no minimum-minutes condition at all. Pick a convention, say which, and apply it to everyone you compare.
How do you calculate a clean sheet percentage?
Divide the clean sheets by the matches played and multiply by 100 — fourteen in thirty-eight is 36.8%. The Premier League used exactly this rate as its Golden Glove tie-break before 2013/14, “the goalkeeper with highest ratio of clean sheets for matches played”, and shares the award instead now.
Why do goals conceded per match and per 90 minutes differ?
Because they divide by different things. Per match divides by appearances; per 90 divides by minutes and rescales to one match’s worth under Law 7’s two halves of 45 minutes. They agree only when the minutes are exactly 90 times the matches, so any substitution or part appearance separates them.
What is a good clean sheet rate?
No source publishes one and this page will not invent one. Both figures describe the whole defence rather than the goalkeeper. The honest use of either is comparing goalkeepers in the same competition over the same season, counted the same way.
