About Powerlifting Weight Class Calculator

The class is the lowest published bracket whose upper limit is not below the lifter's body weight, with the margin and the cut to the class below reported alongside. Sitting a kilogram under a limit is the strongest position in the sport, so knowing the cut required to drop a class is a strategic rather than cosmetic number.

Formulas

Class selection

Assumptions and limits

  • The result is derived only from the 2 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 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
