About this tool
Calories from swing count, bell weight, cadence and rest between sets, anchored on the measured oxygen cost of two-hand kettlebell swings.
This calculator estimates the energy cost of a kettlebell swing session from swing count, bell weight, cadence and rest between sets. It is anchored on the measured oxygen cost of continuous two-hand swings — about 9.8 METs with a 16 kg bell in Farrar, Mayhew and Koch's 2010 study — then scaled for how heavy your bell is relative to your own body mass and how fast you swing, and converted with the ACSM equation kcal/min = METs x 3.5 x kg / 200. Rest between sets is costed separately at 2 METs, because that is where most of the clock in a swing session actually goes.

Starts from a published oxygen-cost measurement of swings, not a generic weight-training MET.
Scales intensity by the bell-to-body-mass ratio instead of ignoring the load you chose.
Separates swinging minutes from resting minutes so a long-rest session is not overstated.
Roughly 46 kcal for an 80 kg person swinging a 16 kg bell continuously at 30 swings a minute, which is about 0.46 kcal a swing. Spread the same 100 swings across five sets with a minute of rest and the session total rises to about 60 kcal, but only because the clock is longer.
Yes — continuous two-hand swings have been measured at roughly 9.8 METs, comparable to running at about 8 to 9 km/h, with average heart rates around 165 bpm in the same study. That makes swings an unusually efficient way to combine a strength stimulus with a genuine cardiovascular one.
It does, but less than proportionally. Moving from a 16 kg to a 24 kg bell at 80 kg body weight raises the estimated intensity by roughly a fifth, not by half, because a large part of the effort is accelerating your own trunk and hips, which does not change with the bell.
Common programmes sit between 100 and 300 swings a session, built from sets of 10 to 20 with enough rest to keep the hip hinge sharp. Volume matters less than form: swings are a hip-hinge power movement, and once the back starts rounding the set is over regardless of the number on the plan.
