Estimate calories and kilojoules burned playing squash, based on your body weight, session duration, and whether you were playing a relaxed general/recreational game or a genuinely competitive, vigorous match — one of the most physically demanding racquet sports played in Australian clubs.
Squash calorie burn depends heavily on how competitively it's played, captured here as two tiers: general/recreational play (MET 7.3) and competitive/vigorous match play (MET 12.0) — one of the highest MET values of any racquet sport on this site. The formula is calories = MET × body weight (kg) × session duration (hours). A 75 kg player on court for 45 minutes (0.75 hours) burns around 411 kcal (about 1,718 kJ) in general recreational play, and around 675 kcal (about 2,824 kJ) in a genuine competitive, vigorous match — a spread of roughly 64% between the two tiers for the exact same body and the exact same 45 minutes on the clock.
| Tier | MET | Calories | Kilojoules |

The calculation combines three inputs: a MET (Metabolic Equivalent of Task) value for how hard the session was actually contested, your body weight, and the time you spent on court. This calculator uses two MET tiers drawn from the squash activity codes in the 2024 Adult Compendium of Physical Activities — general/recreational squash (code 15652, MET 7.3) and competitive, vigorous match play (code 15650, Taylor Code 530, MET 12.0) — because squash's small, enclosed court and near-continuous rallying mean the gap between a relaxed hit-around and a genuinely competitive match is unusually large compared with most other sports on this site.
Squash is played inside a small, fully enclosed box of a court with no out-of-bounds — the ball simply keeps coming back off the walls, so a competitive rally rarely offers a natural break the way a wide tennis court or a stop-start badminton point often does. That confinement forces near-constant sprinting to the front corners, deep lunges to dig a low ball out of the back corner, and rapid changes of direction as you scramble back to the centre of the court (the "T") between shots, with only a split second of recovery before the next shot arrives. Stack that up over a genuinely contested game and it's easy to see why competitive, vigorous squash carries a MET value of 12.0 — one of the highest figures assigned to any racquet sport in the Compendium, and noticeably higher than the top competitive tiers used on this site for tennis or badminton.
It's worth being upfront, though, that a real squash match is not one unbroken 45-minute sprint. Genuine games include short breaks between games and points where a serve is being set up, and even elite matches have natural lulls in intensity. The MET value of 12.0 reflects the documented average effort of a competitive, vigorously contested game, so a full match that includes rest between games may still average out somewhat below what the peak-intensity feeling of the hardest rallies would suggest — treat it as a solid, honest estimate for a genuinely hard session rather than a claim that every single minute is run at that exact intensity.
General/recreational squash, by contrast, is what most casual and social players are actually doing most of the time: rallying to keep the ball going, mixed-ability hitting with a friend, or a relaxed game without serious competitive intent. It's still a solid, moderately vigorous workout — squash's small court means even a gentle game involves more movement than a relaxed hit in many other sports — but it's honest to say it doesn't come close to the physical demand of a hard-fought competitive match, even though both are unmistakably "playing squash" by any casual description.
| Body Weight | MET | Calories (45 min, competitive/vigorous) | Kilojoules |
|---|---|---|---|
| 55 kg | 12.0 | 495 kcal | 2,071 kJ |
| 65 kg | 12.0 | 585 kcal | 2,448 kJ |
| 75 kg | 12.0 | 675 kcal | 2,824 kJ |
| 85 kg | 12.0 | 765 kcal | 3,201 kJ |
| 95 kg | 12.0 | 855 kcal | 3,577 kJ |
This table holds the intensity constant at competitive/vigorous match play (MET 12.0) for a 45-minute session, so you can see how much body weight alone changes the total — a 95 kg player burns roughly 73% more than a 55 kg player in the identical session, purely because body weight is a straight multiplier in the formula.
Here body weight is fixed at 75 kg and duration at a full hour, so you can compare how much the intensity tier alone changes the burn rate.
| Tier | MET | Calories/Hour | Calories/Minute |
|---|---|---|---|
| General / recreational play | 7.3 | 548 kcal/hr | 9.13 kcal/min |
| Competitive / vigorous match play | 12.0 | 900 kcal/hr | 15.00 kcal/min |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth seeing your session in the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 75 kg player in a 45-minute competitive/vigorous squash session burns about 675 kcal, which is roughly 2,824 kJ — useful if you want to weigh your session against the energy value printed on a post-match sports drink or snack.
How many calories does squash burn?
It depends heavily on how competitively the session was played. A 75 kg player on court for 45 minutes burns around 411 kcal in general recreational play (MET 7.3), and around 675 kcal in a genuine competitive, vigorous match (MET 12.0) — one of the highest MET values of any racquet sport on this site. Lighter or heavier players will see proportionally lower or higher numbers, so use the calculator above with your own weight and session length for a personalised estimate.
Why does squash burn so many more calories than most other racquet sports?
Squash is played in a small, fully enclosed court with no out-of-bounds and very short distances between shots, which means points tend to become near-continuous rallies of sprinting, lunging and rapid changes of direction with almost no natural break between shots. Sports played on larger courts, like tennis, or with more stop-start structure, like badminton, still involve real bursts of effort but typically allow slightly more recovery within a rally. That near-constant movement in a confined space is the most likely reason competitive squash's MET value of 12.0 sits at or above the top of the racquet-sport MET values used across this site.
Is squash safe for beginners given how intense it is?
Squash can be played at a genuinely gentle, exploratory pace when you're new to it, which is closer to the general/recreational tier used in this calculator than the competitive one. The main risks for beginners are usually more about collisions with the wall, the ball, or an opponent in a small shared space, and overuse strain from lunging on a hard court, rather than the cardiovascular demand itself. Building up gradually, wearing eye protection, and learning basic court etiquette and right-of-way rules are commonly recommended for new players — but this is general information, not a substitute for advice from a qualified instructor or health professional about your own situation.
Does squash doubles or racquetball-style scoring change the number?
Not in this calculator. The two MET values used here come from the Compendium's general squash codes rather than a format-specific figure, and squash doubles is far less common than singles in most Australian clubs. If you regularly play a doubles or racquetball-style variant, treat these figures as a reasonable approximation rather than an exact one, since court-sharing between partners would likely reduce individual ground covered somewhat, similar to the doubles-versus-singles gap seen in tennis and badminton.
How does squash compare to running for calorie burn?
Competitive, vigorous squash's MET of 12.0 sits above even a fast recreational run, putting it among the more demanding cardio activities tracked on this site pound-for-pound. General recreational squash at MET 7.3 is closer to a solid jogging pace. As with any comparison across very different activities, actual effort still depends heavily on your own pace, fitness level and how continuously you're moving, so treat this as a broad comparison rather than an exact equivalence.
Does this include time between points and games, or just active rallying?
The MET values are whole-session averages, so they already blend together the sprinting and lunging during rallies with the brief pauses between points and the short breaks between games. They're not a per-rally figure. A genuine match with several games and proper rest breaks between them will likely average out somewhat below the peak-intensity feeling of the most intense individual rallies, even though the overall session is still coded at the higher MET tier.
What if I only play squash socially and casually — should I use the general tier?
Yes. The general/recreational tier (MET 7.3) — which is also the calculator's default — is intended for exactly that kind of session: rallying to keep the ball going, mixed-ability hitting, or a relaxed game without serious competitive intent. Reserve the competitive/vigorous tier (MET 12.0) for genuinely hard-fought, high-intensity matches where you're sprinting and lunging for most points.
What are the limitations of this calorie estimate?
This calculator uses published MET values multiplied by your body weight and session time, which gives a solid population-level estimate rather than a personalised one. It doesn't account for your fitness level, how many of your rallies were genuinely intense versus how much time you spent recovering between points and games, your opponent's standard, or how the two tiers used here blur together in a real match that shifts in intensity from point to point. Use the result as a reasonable planning figure rather than an exact measurement.
