Swimming Calorie Calculator

Estimate calories burned during swimming based on your stroke style, body weight, and swim duration. The calculator uses MET values from the Compendium of Physical Activities to compare recreational and intense swimming, treading water, aqua jogging, and water aerobics.

Swimming Calorie Formula

Calories per minute follow (MET × weight in kg × 3.5) ÷ 200. Multiply by your swim duration in minutes for total calories burned. Higher-intensity strokes like butterfly and breaststroke have higher MET values than relaxed treading water.

Comparing Water Activities

Freestyle crawl at moderate effort burns more calories than water walking, while butterfly ranks among the highest. Pair results with the Running Calorie Calculator or Swimming Time Calculator to plan training sessions.

Frequently Asked Questions

How many calories does swimming burn per hour?

A 70 kg swimmer doing recreational freestyle burns roughly 350 to 450 kcal per hour. Intense butterfly can exceed 700 kcal per hour for the same weight.

Which swimming stroke burns the most calories?

Butterfly typically has the highest MET value, followed by intense breaststroke and crawl. Relaxed treading water burns the fewest calories per minute.

Does body weight affect swim calorie burn?

Yes. The MET formula multiplies by body weight in kilograms, so heavier swimmers burn more calories for the same stroke and duration.

Is swimming good for weight loss?

Swimming provides a full-body, low-impact workout that burns significant calories. Combine regular swim sessions with a balanced diet for sustainable weight management.
