How this instrument works
Football's energy cost swings enormously with intensity, which is why the 2024 Adult Compendium of Physical Activities gives it three distinct MET codes rather than one. Competitive soccer or football — the kind played at pace with real tactical pressure, the level a World Cup match is played at — sits at 9.5 METs, reflecting the constant sprinting, changes of direction, and high heart rate the format demands. Casual, recreational football drops to 7.0 METs, and walking football, a growing lower-impact format designed for older or less mobile players, sits at just 3.5 METs — a third of the competitive rate.
The calculator uses the standard kcal = MET x weight (kg) x duration (hours) formula, with duration entered in minutes and converted to hours internally. It defaults to 90 minutes, a regulation football match under IFAB's Laws of the Game (the body that sets the rules FIFA competitions play by), but works for any duration — a 20-minute training drill, a 60-minute five-a-side game, or a full 90-minute match with stoppage time approximated as part of the total.
Because the formula treats the whole session as one continuous intensity, it's a simplification of how a real match actually unfolds — players sprint, jog, and stand between plays rather than sustaining one constant effort. Picking the intensity option that best matches your average exertion across the whole game, rather than your peak sprint effort, gives the most representative total.
- Choose an intensity: competitive, casual/recreational, or walking football, each mapped to a Compendium MET code.
- Enter your body weight in kilograms — heavier players expend more energy covering the same pitch at the same intensity.
- Enter the match or session duration in minutes; it defaults to 90 for a full regulation match.
- Read the calories burned total, then compare competitive and casual intensity for the same match length.
Worked example — competitive match, 70 kg, 90 minutes
A 70 kg midfielder plays a full 90-minute competitive match at genuine match intensity — the Compendium's 9.5-MET competitive soccer code. Ninety minutes is 1.5 hours, so the calculation is 9.5 MET x 70 kg x 1.5 hours = 997.5 kcal for the full match.
The same player at the same weight and duration, but in a casual recreational game instead, drops to 7.0 METs: 7.0 x 70 x 1.5 = 735.0 kcal — 262.5 fewer calories across 90 minutes purely from playing at a lower gear, even covering roughly the same pitch.
Questions
How many calories does playing a full football match burn?
For a 70 kg player, a full 90-minute competitive match burns about 997.5 kcal (9.5 MET), a casual recreational game about 735 kcal (7.0 MET), and a 90-minute walking-football session around 367.5 kcal (3.5 MET). Heavier players burn proportionally more at every intensity, since the formula multiplies MET by body weight directly.
Why is competitive football rated so much higher than casual play?
Because match data shows elite and competitive players cover far more distance at high speed — repeated sprints, quick changes of direction, and sustained high heart rate across 90 minutes — compared with a casual kickabout, where play is slower and stoppages are more frequent. The Compendium's 9.5 MET competitive code reflects that measured intensity gap, not just a subjective 'harder game' label.
What is walking football and why does it burn so much less?
Walking football is a modified format, popular with older adults and players returning from injury, where running is not allowed and players must keep at least one foot in contact with the ground at walking pace. That rule change removes the sprinting and rapid direction changes that drive up competitive football's energy cost, which is why the Compendium codes it at just 3.5 METs — closer to a brisk walk than a match.
How long is a regulation football match?
A standard match runs two equal halves of 45 minutes each under IFAB's Laws of the Game, for 90 minutes of regulation play, plus a half-time interval and any stoppage time the referee adds for delays. This calculator defaults its duration field to 90 minutes for exactly that reason, though you can enter any length for training sessions, five-a-side games, or youth matches with shorter halves.
Does playing position change how many calories I burn?
Almost certainly, but the Compendium's football codes don't split by position — a central midfielder typically covers more total distance than a goalkeeper, for instance. Choosing the intensity option that reflects your actual average effort across the match, rather than the nominal 'competitive' label, is the best way to account for a lower-output position like goalkeeper.
Is this the same formula used for other team sports calculators?
Yes — every activity-based calculator in this MET-based series, from running to swimming to stair climbing, uses the identical kcal = MET x weight x duration formula from the 2024 Adult Compendium of Physical Activities. Only the MET value changes between activities and intensities; the underlying arithmetic is consistent across all of them.
