About the Wilks Formula
Calculate your Wilks score to compare your powerlifting performance across different body weights and sexes. The Wilks formula provides a standardized way to evaluate strength.

The Wilks formula was developed by Robert Wilks to allow fair comparison of powerlifting performance across different body weights and sexes. It uses mathematical coefficients to normalize total weight lifted.

A higher Wilks score indicates better relative strength. Elite powerlifters typically score 500+ while beginners usually score under 300. The formula remains one of the most widely used powerlifting comparison tools.
