Swimming Calories Calculator
Estimate calories burned swimming by stroke and intensity.
About Swimming Calories Calculator
Swimming MET values vary widely by stroke, with butterfly more than double moderate freestyle. Water resistance means energy cost per hundred metres far exceeds the equivalent distance on land. Swimming burns more per unit distance than running but less per unit time at recreational intensity, because sustainable swimming speeds are much lower.
Formula
Swimming Calories
Calories per minute = MET × 3.5 × weight in kg ÷ 200
- MET
- Metabolic equivalent for the stroke and intensity
- butterfly
- The most demanding stroke at around 13.8 MET

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
- These figures are estimates based on population-average formulas and are intended for training and recreational planning only. They are not medical advice. Consult a qualified health professional before starting or changing an exercise programme, particularly if you have an existing medical condition.
- This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

Frequently Asked Questions
How is Swimming Calories calculated?
Calories per minute = MET × 3.5 × weight in kg ÷ 200 Swimming MET values vary widely by stroke, with butterfly more than double moderate freestyle. Water resistance means energy cost per hundred metres far exceeds the equivalent distance on land.
Why does Swimming Calories matter?
Swimming burns more per unit distance than running but less per unit time at recreational intensity, because sustainable swimming speeds are much lower.
What values do I need to enter?
This calculator takes 4 inputs: Body weight, Duration, Stroke, Distance covered. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
