Squash is a fast-moving court sport that combines short sprints, lunges, and quick racket swings. The number of calories you burn in a 30-minute session depends primarily on your body weight and how hard you play — a relaxed rally burns far less than a competitive match. This calculator estimates your energy expenditure using the standard MET (metabolic equivalent) method.
Built for club players, weekend competitors, and fitness enthusiasts, this tool lets you enter your weight in kilograms or pounds, choose an intensity level, and adjust the session length. It returns estimated calories for your 30-minute window, along with a per-minute rate and projected hourly burn. Use it to compare sessions, plan post-match snacks, or understand how the sport contributes to your overall daily energy balance.

How It Works
This calculator uses the standard metabolic equivalent (MET) method recommended by exercise physiologists. A MET value expresses how many times more energy you burn during an activity compared with sitting quietly at rest. One MET is roughly 1 kcal per kilogram of body weight per hour. The formula is:
Calories burned = MET × 3.5 × weight (kg) × duration (minutes) ÷ 200
The 3.5 in the numerator represents the approximate oxygen cost of 1 MET in milliliters per kilogram per minute (3.5 mL/kg/min), and the 200 converts that to kilocalories per minute. Because squash involves stop-and-go sprinting, lunging, and rapid changes of direction, it earns a relatively high MET value compared with steady-paced walking. This tool applies the MET values published in the Compendium of Physical Activities: approximately 5.5 for social rally play, 7.3 for general play, and 12.3 for competitive match play.
How to Get the Best Estimate
- Weigh yourself in the morning or before the session and enter the figure in kilograms or pounds.
- Select the intensity that best matches your typical squash session. If you play mostly rallies with moderate effort, choose General play.
- Adjust the duration if you want to estimate a session longer or shorter than 30 minutes. The default is 30 minutes.
- Press Calculate Calories and review the breakdown. The main number is your estimated calorie expenditure for the full session.
- Use Reset to clear the form and try another weight or intensity.
For a more personalized number, wear a heart-rate monitor and compare its calorie reading with this estimate. Keep in mind that warm-up time, resting between games, and time spent retrieving the ball all lower the actual active calorie burn.
Worked Examples
Example 1: A 60 kg player enjoying a social rally for 30 minutes (MET 5.5): 5.5 × 3.5 × 60 ÷ 200 × 30 = 173 kcal.
Example 2: An 80 kg player in a general club match for 30 minutes (MET 7.3): 7.3 × 3.5 × 80 ÷ 200 × 30 = 307 kcal.
Example 3: A 75 kg competitor in an intense singles match for 30 minutes (MET 12.3): 12.3 × 3.5 × 75 ÷ 200 × 30 = 484 kcal.
Notice that doubling the MET value roughly doubles the calories burned, which is why competitive play makes such a difference in total energy expenditure.
Reference: MET Values for Squash
| Intensity | MET value | Approx. calories per 30 min (70 kg) |
|---|---|---|
| Social / light rally | 5.5 | 202 kcal |
| General play | 7.3 | 268 kcal |
| Competitive match | 12.3 | 452 kcal |
Values are rounded estimates; individual results vary with age, fitness, body composition, and effort.
Tips & Best Practices
- Weigh yourself consistently before exercise, ideally without shoes and heavy clothing, so your comparisons are meaningful.
- If a session includes lengthy breaks for coaching or chatting, reduce the duration accordingly rather than counting the whole time on court.
- Use the per-minute figure to compare squash with other activities. Per minute, competitive squash burns more than many steady-state cardio options.
- Don't use calorie estimates to justify unlimited snacks. Research suggests fitness trackers can overestimate expenditure by 20–30%, so treat the number as a guide.
- Combine the estimate with your maintenance calorie needs to see how squash sessions fit into your weekly energy balance.
For a low-impact off-court day, try the walking calories per hour calculator or the badminton 30-minute calculator to compare calorie burn across activities.
Frequently Asked Questions
How accurate is the MET formula?
MET values come from laboratory measurements of groups of people, so they are population averages rather than exact predictions for you. The formula typically predicts calorie burn within roughly 15–20% for most recreational exercisers. Your actual burn depends on muscle mass, skill level, ambient temperature, and how relentlessly you chase every drop shot.
Does playing doubles change the estimate?
Yes. Doubles keep you on court but involve longer rest and less court coverage. If you play doubles, choose the Social/light rally option or reduce your effective playing time by 10–20%.
Can I use this calculator for interval training?
Squash itself is an interval sport, and the MET values already account for the stop-and-go nature. If you deliberately train with drills and minimal rest, select Competitive match for a closer estimate.
Why is weight important?
Larger bodies require more energy to move around the court, so the formula multiplies by your weight in kilograms. This is why the same 30-minute match can produce very different calorie totals for a 55 kg player and a 95 kg player.
