Swimming calories burned
190 calories
Energy above rest: about 150 kcal.
What do the numbers mean?
Total expenditure includes the energy your body would use at rest during the same time. Energy above rest subtracts that resting portion. Do not add exercise again if it is already included in your daily budget.

Log your activity in Calotank
Meals use your daily budget; logged activity adds calories to it. Manual logging is free.
1. Add activity
Open activity logging and enter the calories and an optional name. This example logs a walk at 400 kcal.
2. See the updated balance
Before logging, 1,400 kcal remains. After logging: 1,400 + 400 = 1,800 kcal. The orange portion shows calories added through activity.

Exercise calorie questions
Which swimming option matches my swim?
The options describe recreational breaststroke and slow or fast freestyle laps. They are not universal effort levels for every swimming stroke. Technique and actual effort can differ even within the same stroke.
What about rests at the pool edge?
Enter active swimming time. If a one-hour pool visit includes 15 minutes of long rests, use 45 minutes in this example. The calculator does not separately estimate rest periods or water-temperature effects.
Why does my smartwatch give a different number?
The calculator uses an average MET value, weight and time. A watch may also use heart rate and its own model. One number may include resting expenditure while the other counts only active calories. Both are estimates; compare the same duration and definition first.
Can I add exercise calories to my daily budget?
Activity logged manually in Calotank adds to your daily budget. Total expenditure includes calories you would use at rest, so it does not directly equal an extra budget. Even some expenditure above rest may already be included in your daily budget. Only account for additional exercise not already included, and avoid logging the same activity twice.
Does this calculate a full day’s expenditure?
This calculator estimates expenditure during a selected exercise session. Use the daily calorie needs calculator for a whole-day estimate based on resting metabolism and your usual activity. Open daily calorie needs →
How are calories burned calculated?
Total expenditure (kcal) = MET × weight (kg) × time (min) ÷ 60. Energy above rest = (MET − 1) × weight × time ÷ 60. One MET represents a standard resting expenditure of 1 kcal/kg/hour.
Example: 5.3 × 70 × 30 ÷ 60 = 185.5 kcal, or about 190 calories. Energy above rest is about 150 kcal.
Results are rounded to the nearest 10 kcal; values below 10 are shown as “< 10”. The source dataset covers adults aged 19–59. The estimate does not measure your own metabolism; fitness, technique, terrain and conditions affect expenditure. This is not a full-day calorie target.
